A JOURNEY
IN OTHER WORLDS
A ROMANCE OF THE FUTURE

BY JOHN JACOB ASTOR




PREFACE.



The protracted struggle between science and the classics appears
to be drawing to a close, with victory about to perch on the
banner of science, as a perusal of almost any university or
college catalogue shows.  While a limited knowledge of both Greek
and Latin is important for the correct use of our own language,
the amount till recently required, in my judgment, has been
absurdly out of proportion to the intrinsic value of these
branches, or perhaps more correctly roots, of study.  The
classics have been thoroughly and painfully threshed out, and it
seems impossible that anything new can be unearthed.  We may
equal the performances of the past, but there is no opportunity
to surpass them or produce anything original.  Even the
much-vaunted "mental training" argument is beginning to pall; for
would not anything equally difficult give as good developing
results, while by learning a live matter we kill two birds with
one stone?  There can be no question that there are many forces
and influences in Nature whose existence we as yet little more
than suspect.  How much more interesting it would be if, instead
of reiterating our past achievements, the magazines and
literature of the period should devote their consideration to
what we do NOT know!  It is only through investigation and
research that inventions come; we may not find what we are in
search of, but may discover something of perhaps greater moment.
It is probable that the principal glories of the future will be
found in as yet but little trodden paths, and as Prof. Cortlandt
justly says at the close of his history, "Next to religion, we
have most to hope from science."

                           CHAPTER 1.

                            JUPITER.

    Jupiter--the magnificent planet with a diameter of 86,500
miles, having 119 times the surface and 1,300 times the volume of
the earth--lay beneath them.

They had often seen it in the terrestrial sky, emitting its
strong, steady ray, and had thought of that far-away planet,
about which till recently so little had been known, and a burning
desire had possessed them to go to it and explore its mysteries.
Now, thanks to APERGY, the force whose existence the ancients
suspected, but of which they knew so little, all things were
possible.

Ayrault manipulated the silk-covered glass handles, and the
Callisto moved on slowly in comparison  with its recent speed,
and all remained glued to their telescopes as they peered through
the rushing clouds, now forming and now dissolving before their
eyes.  What transports of delight, what ecstatic bliss, was
theirs!  Men had discovered and mastered the secret of apergy,
and now, "little lower than the angels," they could soar through
space, leaving even planets and comets behind.

"Is it not strange," said Dr. Cortlandt, "that though it has been
known for over a century that bodies charged with unlike
electricities attract one another, and those charged with like
repel, no one thought of utilizing the counterpart of
gravitation?  In the nineteenth century, savants and Indian
jugglers performed experiments with their disciples and masses of
inert matter, by causing them to remain without visible support
at some distance from the ground; and while many of these, of
course, were quacks, some were on the right track, though they
did not push their research."

President Bearwarden and Ayrault assented.  They were steering
for an apparently hard part of the planet's surface, about a
degree and a half north of its equator.

"Since Jupiter's axis is almost at right angles to  the plane of
its orbit," said the doctor, "being inclined only about one
degree and a half, instead of twenty-three and a half, as was the
earth's till nearly so recently, it will be possible for us to
have any climate we wish, from constantly warm at the equator to
constantly cool or cold as we approach the poles, without being
troubled by extremes of winter and summer."

Until the Callisto entered the planet's atmosphere, its five
moons appeared like silver shields against the black sky, but now
things were looking more terrestrial, and they began to feel at
home.  Bearwarden put down his note-book, and Ayrault returned a
photograph to his pocket, while all three gazed at their new
abode.  Beneath them was a vast continent variegated by chains of
lakes and rivers stretching away in all directions except toward
the equator, where lay a placid ocean as far as their telescopes
could pierce.  To the eastward were towering and massive
mountains, and along the southern border of the continent smoking
volcanoes, while toward the west they saw forests, gently rolling
plains, and table-lands that would have satisfied a poet or set
an agriculturist's heart at rest.  "How I should like to mine
those hills for copper, or drain the swamps to the south!"
exclaimed Col. Bearwarden.  "The Lake Superior mines and the
reclamation of the Florida Everglades would be nothing to this."

"Any inhabitants we may find here have so much land at their
disposal that they will not need to drain swamps on account of
pressure of population for some time," put in the doctor.

"I hope we may find some four-legged inhabitants," said Ayrault,
thinking of their explosive magazine rifles.  "If Jupiter is
passing through its Jurassic or Mesozoic period, there must be
any amount of some kind of game."  Just then a quiver shook the
Callisto, and glancing to the right they noticed one of the
volcanoes in violent eruption.  Smoke filled the air in clouds,
hot stones and then floods of lava poured from the crater, while
even the walls of the hermetically sealed Callisto could not
arrest the thunderous crashes that made the interior of the car
resound.

"Had we not better move on?" said Bearwarden, and accordingly
they went toward the woods they had first seen.  Finding a firm
strip of land between the forest and an arm of the sea, they
gently grounded the Callisto, and not being altogether sure how
the atmosphere of their new abode would suit terrestrial lungs,
or what its pressure to the square inch might be, they cautiously
opened a port-hole a crack, retaining their hold upon it with its
screw.  Instantly there was a rush and a whistling sound as of
escaping steam, while in a few moments their barometer stood at
thirty-six inches, whereupon they closed the opening.

"I fancy," said Dr. Cortlandt, "we had better wait now till we
become accustomed to this pressure.  I do not believe it will go
much higher, for the window made but little resistance when we
shut it."

Finding they were not inconvenienced by a pressure but little
greater than that of a deep coal-mine, they again opened the
port, whereupon their barometer showed a further rise to
forty-two, and then remained stationary.  Finding also that the
chemical composition of the air suited them, and that they had no
difficulty in breathing, the pressure being the same as that
sustained by a diver in fourteen feet of water, they opened a
door and emerged.  They knew fairly well what to expect, and were
not disturbed by their new conditions.  Though they had
apparently gained a good deal in weight as a result of their
ethereal journey, this did not incommode them; for though
Jupiter's volume is thirteen hundred times that of the earth, on
account of its lesser specific gravity, it has but three hundred
times the mass--i. e., it would weigh but three hundred times as
much.  Further, although a cubic foot of water or anything else
weighs 2.5 as much as on earth, objects near the equator, on
account of Jupiter's rapid rotation, weigh one fifth less than
they do at the poles, by reason of the centrifugal force.
Influenced by this fact, and also because they were 483,000,000
miles from the sun, instead of 92,000,000 as on earth, they had
steered for the northern limit of Jupiter's tropics.  And, in
addition to this, they could easily apply the apergetic power in
any degree to themselves when beyond the limits of the Callisto,
and so be attracted to any extent, from twice the pull they
receive from gravitation on earth to almost nothing.

Bearwarden and Ayrault shouldered their rifles, while Dr.
Cortlandt took a repeating shot-gun with No. 4 shot, and, having
also some hunting-knives and a sextant, all three set out in a
northwesterly direction.  The ground was rather soft, and a warm
vapor seemed to rise from it.  To the east the sky was veiled by
dense clouds of smoke from the towering volcanoes, while on their
left the forest seemed to extend without limit.  Clumps of huge
ferns were scattered about, and the ground was covered with
curious tracks.

"Jupiter is evidently passing through a Carboniferous or Devonian
period such as existed on earth, though, if consistent with its
size, it should be on a vastly larger scale," said the doctor.
"I never believed in the theory," he continued, "that the larger
the planet the smaller should be its inhabitants, and always
considered it a makeshift, put forward in the absence of definite
knowledge, the idea being apparently that the weight of very
large creatures would be too great for their strength.  Of the
fact that mastodons and creatures far larger than any now living
on earth existed there, we have absolute proof, though
gravitation must have been practically the same then as now."

Just here they came upon a number of huge bones, evidently the
remains of some saurian, and many times the size of a grown
crocodile.  On passing a growth of most luxuriant vegetation,
they saw a half-dozen sacklike objects, and drawing nearer
noticed that the tops began to swell, and at the same time became
lighter in colour.  Just as the doctor was about to investigate
one of them with his duck-shot, the enormously inflated tops of
the creatures collapsed with a loud report, and the entire group
soared away.  When about to alight, forty yards off, they
distended membranous folds in the manner of wings, which checked
their descent, and on touching the ground remained where they
were without rebound.

"We expected to find all kinds of reptiles and birds," exclaimed
the doctor.  "But I do not know  how we should class those
creatures.  They seem to have pneumatic feet and legs, for their
motion was certainly not produced like that of frogs."

When the party came up with them the heads again began to swell.

"I will perforate the air-chamber of one," said Col. Bearwarden,
withdrawing the explosive cartridge from the barrel of his rifle
and substituting one with a solid ball.  "This will doubtless
disable one so that we can examine it."

Just as they were about to rise, he shot the largest through the
neck.  All but the wounded one, soared off, while Bearwarden,
Ayrault, and Cortlandt approached to examine it more closely.

"You see," said Cortlandt, "this vertebrate--for that is as
definitely as we can yet describe it--forces a great pressure of
air into its head and neck, which, by the action of valves, it
must allow to rush into its very rudimentary lower extremities,
distending them with such violence that the body is shot upward
and forward.  You may have noticed the tightly inflated portion
underneath as they left the ground."

While speaking he had moved rather near, when suddenly a
partially concealed mouth opened, showing the unmistakable tongue
and fangs of a serpent.  It emitted a hissing sound, and the
small eyes gleamed maliciously.

"Do you believe it is a poisonous species?" asked Ayrault.

"I suspect it is," replied the doctor; "for, though it is
doubtless able to leap with great accuracy upon its prey, we saw
it took some time to recharge the upper air-chamber, so that,
were it not armed with poison glands, it would fall an easy
victim to its more powerful and swifter contemporaries, and would
soon become extinct."

"As it will be unable to spring for some time," said Bearwarden,
"we might as well save it the disappointment of trying," and,
snapping the used shell from his rifle, he fired an explosive
ball into the reptile, whereupon about half the body disappeared,
while a sickening odour arose.  Although the sun was still far
above the horizon, the rapidity with which it was descending
showed that the short night of less than five hours would soon be
upon them; and though short it might be very dark, for they were
in the tropics, and the sun, going down perpendicularly, must
also pass completely around the globe, instead of, as in northern
latitudes on earth in summer, approaching the horizon obliquely,
and not going far below it.  A slight and diffused sound here
seemed to rise from the ground all about them, for which they
could not account.  Presently it became louder, and as the sun
touched the horizon, it poured forth in prolonged strains.  The
large trumpet-shaped lilies, reeds, and heliotropes seemed fairly
to throb as they raised their anthem to the sky and the setting
sun, while the air grew dark with clouds of birds that gradually
alighted on the ground, until, as the chorus grew fainter and
gradually ceased, they flew back to their nests.  The three
companions had stood astonished while this act was played.  The
doctor then spoke:

"This is the most marvellous  development of Nature I have seen,
for its wonderful divergence from, and yet analogy to, what takes
place on earth.  You know our flowers offer honey, as it were, as
bait to insects, that in eating or collecting it they may catch
the pollen on their legs and so carry it to other flowers,
perhaps of the opposite sex.  Here flowers evidently appeal to
the sense of hearing instead of taste, and make use of birds, of
which there are enormous numbers, instead of winged insects, of
which I have seen none, one being perhaps the natural result of
the other.  The flowers have become singers by long practice, or
else, those that were most musical having had the best chance to
reproduce, we have a neat illustration of the 'survival of the
fittest.'  The sound is doubtless produced by a shrinking of the
fibres as the sun withdraws its heat, in which case we may expect
another song at sunrise, when the same result will be effected by
their expanding."

Searching for a camping-place in which to pass the coming hours,
they saw lights flitting about like will-o'-the-wisps, but
brighter and intermittent.

"They seem to be as bright as sixteen-candle-power lamps, but the
light is yellower, and appears to emanate from a comparatively
large surface, certainly nine or ten inches square," said the
doctor.

They soon gave up the chase, however, for the lights were
continually moving and frequently went out.  While groping in the
growing darkness, they came upon a brown object about the size of
a small dog and close to the ground.  It flew off with a humming
insect sound, and as it did so it showed the brilliant
phosphorescent glow they had observed.

"That is a good-sized fire-fly," said Bearwarden.  "Evidently the
insects here are on the same scale as everything else.  They are
like the fire-flies in Cuba, which the Cubans are said to put
into a glass box and get light enough from to read by.  Here they
would need only one, if it could be induced to give its light
continuously."

Having found an open space on high ground, they sat down, and
Bearwarden struck his repeater, which, for convenience, had been
arranged for Jupiter time, dividing the day into ten hours,
beginning at noon, midnight being therefore five o'clock.

"Twenty minutes past four," said he, "which would correspond to
about a quarter to eleven on earth.  As the sun rises at
half-past seven, it will be dark about three hours, for the time
between dawn and daylight will, of course, be as short as that we
have just experienced between sunset and night."

"If we stay here long," said the doctor, "I suppose we shall
become accustomed, like sailors, to taking our four, or in this
case five, hours on duty, and five hours off."

"Or," added Ayrault, "we can sleep ten consecutive hours and take
the next ten for exploring and hunting, having the sun for one
half the time and the moons for the other."

Bearwarden and Cortlandt now rolled themselves in their blankets
and were soon asleep, while Ayrault, whose turn it was to watch
till the moons rose--for they had not yet enough confidence in
their new domain to sleep in darkness simultaneously--leaned his
back against a rock and lighted his pipe.  In the distance he saw
the torrents of fiery lava from the volcanoes reflected in the
sky, and faintly heard their thunderous crashes, while the
fire-flies twinkled unconcernedly in the hollow, and the night
winds swayed the fernlike branches.  Then he gazed at the earth,
which, but little above the horizon, shone with a faint but
steady ray, and his mind's eye ran beyond his natural vision
while he pictured to himself the girl of his heart, wishing that
by some communion of spirits he might convey his thoughts to her,
and receive hers.  It was now the first week of January on earth.
He could almost see her house and the snow-clad trees in the
park, and knew that at that hour she was dressing for dinner, and
hoped and believed that he was in her heart.  While he thus
mused, one moon after another rose, each at a different phase,
till three were at once in the sky.  Adjusting the electric
protection- wires that were to paralyze any creature that
attempted to come within the circle, and would arouse them by
ringing a bell, he knocked the ashes from his pipe, rolled
himself in a blanket, and was soon asleep beside his friends.



                           CHAPTER II.


                          ANTECEDENTAL.

"Come in!" sounded a voice, as Dr. Cortlandt and Dick Ayrault
tapped at the door of the President of the Terrestrial Axis
Straightening Company's private office on the morning of the 21st
of June, A. D. 2000.  Col. Bearwarden sat at his capacious desk,
the shadows passing over his face as April clouds flit across the
sun.  He was a handsome man, and young for the important post he
filled--being scarcely forty--a graduate of West Point, with
great executive ability, and a wonderful engineer.  "Sit down,
chappies," said he; "we have still a half hour before I begin to
read the report I am to make to the stockholders and
representatives of all the governments, which is now ready.  I
know YOU smoke," passing a box of Havanas to the professor.

Prof. Cortlandt, LL. D., United States Government expert,
appointed to examine the company's calculations, was about fifty,
with a high forehead, greyish hair, and quick, grey eyes, a
geologist and astronomer, and altogether as able a man, in his
own way, as Col. Bearwarden in his.  Richard Ayrault, a large
stockholder and one of the honorary vice-presidents in the
company, was about thirty, a university man, by nature a
scientist, and engaged to one of the prettiest society girls, who
was then a student at Vassar, in the beautiful town of
Poughkeepsie.

"Knowing the way you carry things in your mind, and the
difficulty of rattling you," said Cortlandt, "we have dropped in
on our way to hear the speech that I would not miss for a
fortune.  Let us know if we bother you."

"Impossible, dear boy," replied the president genially.  "Since I
survived your official investigations, I think I deserve some of
your attention informally."

"Here are my final examinations," said Cortlandt, handing
Bearwarden a roll of papers.  "I have been over all your figures,
and testify to their accuracy in the appendix I have added."

So they sat and chatted about the enterprise that interested
Cortlandt and Ayrault almost as much as Bearwarden himself.  As
the clock struck eleven, the president of the company put on his
hat, and, saying au revoir to his friends, crossed the street to
the Opera House, in which he was to read a report that would be
copied in all the great journals and heard over thousands of
miles of wire in every part of the globe.  When he arrived, the
vast building was already filled with a distinguished company,
representing the greatest intelligence, wealth, and powers of the
world.  Bearwarden went in by the stage entrance, exchanging
greetings as he did so with officers of the company and directors
who had come to hear him.  Cortlandt and Ayrault entered by the
regular door, the former going to the Government representatives'
box, the latter to join his fiancee, Sylvia Preston, who was
there with her mother.  Bearwarden had a roll of manuscript at
hand, but so well did he know his speech that he scarcely glanced
at it.  After being introduced by the chairman of the meeting,
and seeing that his audience was all attention, he began, holding
himself erect, his clear, powerful voice making every part of the
building ring.



                          CHAPTER III.

                 PRESIDENT BEARWARDEN'S SPEECH.

"To the Bondholders and Stockholders of the Terrestrial Axis
Straightening Company and Representatives of Earthly Governments.

"GENTLEMEN:  You know that the objects of this company are, to
straighten the axis of the earth, to combine the extreme heat of
summer with the intense cold of winter and produce a uniform
temperature for each degree of latitude the year round.  At
present the earth's axis--that is, the line passing through its
centre and the two poles--is inclined to the ecliptic about
twenty-three and a half degrees.  Our summer is produced by the
northern hemisphere's leaning at that angle towards the sun, and
our winter by its turning that much from it.  In one case the
sun's rays are caused to shine more perpendicularly, and in the
other more obliquely.  This wabbling, like that of a top, is the
sole cause of the seasons; since, owing to the eccentricity of
our orbit, the earth is actually fifteen hundred thousand miles
nearer the sun during our winter, in the northern hemisphere,
than in summer.  That there is no limit to a planet's
inclination, and that inclination is not essential, we have
astronomical proof.  Venus's axis is inclined to the plane of her
orbit seventy-five degrees, so that the arctic circle comes
within fifteen degrees of the equator, and the tropics also
extend to latitude seventy-five degrees, or within fifteen
degrees of the poles, producing great extremes of heat and cold.

"Venus is made still more difficult of habitation by the fact
that she rotates on her axis in the same time that she revolves
about the sun, in the same way that the moon does about the
earth, so that one side must be perpetually frozen while the
other is parched.

"In Uranus we see the axis tilted still further, so that the
arctic circle descends to the equator.  The most varied climate
must therefore prevail during its year, whose length exceeds
eighty-one of ours.

The axis of Mars is inclined about twenty-eight and two thirds
degrees to the plane of its orbit; consequently its seasons must
be very similar to ours, the extremes of heat and cold being
somewhat greater.

"In Jupiter we have an illustration of a planet whose axis is
almost at right angles to the plane of its orbit, being inclined
but about a degree and a half.  The hypothetical inhabitants of
this majestic planet must therefore have perpetual summer at the
equator, eternal winter at the poles, and in the temperate
regions everlasting spring.  On account of the straightness of
the axis, however, even the polar inhabitants--if there are
any--are not oppressed by a six months' night, for all except
those at the VERY pole have a sunrise and a sunset every ten
hours--the exact day being nine hours, fifty five minutes, and
twenty-eight seconds.  The warmth of the tropics is also tempered
by the high winds that must result from the rapid whirl on its
axis, every object at the equator being carried around by this at
the rate of 27,600 miles an hour, or over three thousand miles
farther than the earth's equator moves in twenty-four hours.

"The inclination of the axis of our own planet has also
frequently considerably exceeded that of Mars, and again has been
but little greater than Jupiter's at least, this is by all odds
the most reasonable explanation of the numerous Glacial periods
through which our globe has passed, and of the recurring mild
spells, probably lasting thousands of years, in which elephants,
mastodons, and other semi-tropical vertebrates roamed in Siberia,
some of which died so recently that their flesh, preserved by the
cold, has been devoured by the dogs of modern explorers.

"It is not to be supposed that the inclining of the axes of
Jupiter, Venus, the Earth, and the other planets, is now fixed;
in some cases it is known to be changing.  As long ago as 1890,
Major-Gen. A. W. Drayson, of the British Army, showed, in a work
entitled Untrodden Ground in Astronomy and Geology, that, as a
result of the second rotation of the earth, the inclination of
its axis was changing, it having been 23@ 28' 23" on January 1,
1750, 23@ 27' 55.3" on January 1, 1800, and 23@ 27' 30.9" on
January 1, 1850; and by calculation one hundred and ten years ago
showed that in 1900 (one hundred years ago) it would be 23@ 27'
08.8".  This natural straightening is, of course, going on, and
we are merely about to anticipate it.  When this improvement was
mooted, all agreed that the EXTREMES of heat and cold could well
be spared.  'Balance those of summer against those of winter by
partially straightening the axis; reduce the inclination from
twenty-three degrees, thirty minutes, to about fifteen degrees,
but let us stop there,' many said.  Before we had gone far,
however, we found it would be best to make the work complete.
This will reclaim and make productive the vast areas of Siberia
and the northern part of this continent, and will do much for the
antarctic regions; but there will still be change in temperature;
a wind blowing towards the equator will always be colder than one
blowing from it, while the slight eccentricity of the orbit will
supply enough change to awaken recollections of seasons in our
eternal spring.

"The way to accomplish this is to increase the weight of the pole
leaving the sun, by increasing the amount of material there for
the sun to attract, and to lighten the pole approaching or
turning towards the sun, by removing some heavy substance from
it, and putting it preferably at the opposite pole.  This
shifting of ballast is most easily accomplished, as you will
readily perceive, by confining and removing water, which is
easily moved and has a considerable weight.  How we purpose to
apply these aqueous brakes to check the wabbling of the earth, by
means of the attraction of the sun, you will now see.

"From Commander Fillmore, of the Arctic Shade and the Committee
on Bulkheads and Dams, I have just received the following by
cable telephone: 'The Arctic Ocean is now in condition to be
pumped out in summer and to have its average depth increased one
hundred feet by the dams in winter.  We have already fifty
million square yards of windmill turbine surface in position and
ready to move.  The cables bringing us currents from the dynamos
at Niagara Falls are connected with our motors, and those from
the tidal dynamos at the Bay of Fundy will be in contact when
this reaches you, at which moment the pumps will begin.  In
several of the landlocked gulfs and bays our system of confining
is so complete, that the surface of the water can be raised two
hundred feet above sea- level.  The polar bears will soon have to
use artificial ice.  Perhaps the cheers now ringing without may
reach you over the telephone.'"

The audience became greatly interested, and when the end of the
telephone was applied to a microphone the room fairly rang with
exultant cheers, and those looking through a kintograph (visual
telegraph) terminating in a camera obscura on the shores of
Baffin Bay were able to see engineers and workmen waving and
throwing up their caps and falling into one another's arms in
ecstasies of delight.  When the excitement subsided, the
president continued:

"Chairman Wetmore, of the Committee on Excavations and
Embankments in Wilkesland and the Antarctic Continent, reports:
'Two hundred and fifty thousand square miles are now hollowed out
and enclosed sufficiently to hold water to an average depth of
four hundred feet.  Every summer, when the basin is allowed to
drain, we can, if necessary, extend our reservoir, and shall have
the best season of the year for doing work until the earth has
permanent spring.  Though we have comparatively little water or
tidal power, the earth's crust is so thin at this latitude, on
account of the flattening, that by sinking our tubular boilers
and pipes to a depth of a few thousand feet we have secured so
terrific a volume of superheated steam that, in connection with
our wind turbines, we shall have no difficulty in raising half a
cubic mile of water a minute to our enclosure, which is but
little above sea-level, and into which, till the pressure
increases, we can fan or blow the water, so that it can be full
three weeks after our longest day, or, since the present
unimproved arrangement gives the indigenes but one day and night
a year, I will add the 21st day of December.

"'We shall be able to find use for much of the potential energy
of the water in the reservoir when we allow it to escape in June,
in melting some of the accumulated polar ice-cap, thereby
decreasing still further the weight of this pole, in lighting and
warming ourselves until we get the sun's light and heat, in
extending the excavations, and in charging the storage batteries
of the ships at this end of the line.  Everything will be ready
when you signal "Raise water."'"

"Let me add parenthetically," said Bearwarden, "that this means
of obtaining power by steam boilers sunk to a great depth is much
to be commended; for, though the amount of heat we can withdraw
is too small to have much effect, the farther towards the centre
our globe can be cooled the deeper will the water of the oceans
be able to penetrate--since it is its conversion into steam that
prevents the water from working its way in farther--and the more
dry land we shall have."

"You see," the president continued, "the storage capacity at the
south pole is not quite as great as at the north, because it is
more difficult to excavate a basin than to close the exits of one
that already exists, which is what we have done in the arctic.
The work is also not so nearly complete, since it will not be
necessary to use the southern reservoir for storing weight for
six months, or until the south pole, which is now at its maximum
declination from the sun, is turned towards it and begins to move
away; then, by increasing the amount of matter there, and at the
same time lightening the north pole, and reversing the process
every six months, we decrease the speed at which the departing
pole leaves the sun and at which the approaching pole advances.
The north pole, we see, will be a somewhat more powerful lever
than the south for working the globe to a straight position, but
we may be sure that the latter, in connection with the former,
will be able to hold up its end."

[The building here fairly shook with applause, so that, had the
arctic workers used the microphone, they might have heard in the
enthusiastic uproar a good counterpart of their own period.]

"I only regret," the president continued, "that when we began
this work the most marvellous force yet discovered--apergy--was
not sufficiently understood to be utilized, for it would have
eased our labours to the point of almost eliminating them.  But
we have this consolation: it was in connection with our work that
its applicability was discovered, so that had we and all others
postponed our great undertaking on the pretext of waiting for a
new force, apergy might have continued to lie dormant for
centuries.  With this force, obtained by simply blending negative
and positive electricity with electricity of the third element or
state, and charging a body sufficiently with this fluid,
gravitation is nullified or partly reversed, and the earth repels
the body with the same or greater power than that with which it
still attracts or attracted it, so that it may be suspended or
caused to move away into space.  Sic itur ad astra, we may say.
With this force and everlasting spring before us, what may we not
achieve?  We may some day be able to visit the planets, though
many may say that, since the axes of most of those we have
considered are more inclined than ours, they would rather stay
here.  'Blessed are they that shall inherit the earth,'" he went
on, turning a four-foot globe with its axis set vertically and at
right angles to a yellow globe labelled "Sun"; and again waxing
eloquent, he added:  "We are the instruments destined to bring
about the accomplishment of that prophecy, for never in the
history of the world has man reared so splendid a monument to his
own genius as he will in straightening the axis of the planet.

"No one need henceforth be troubled by sudden change, and every
man can have perpetually the climate he desires.  Northern Europe
will again luxuriate in a climate that favoured the elephants
that roamed in northern Asia and Switzerland.  To produce these
animals and the food they need, it is not necessary to have great
heat, but merely to prevent great cold, half the summer's sun
being absorbed in melting the winter's accumulation of ice.

"When the axis has reached a point at which it inclines but about
twelve degrees, it will become necessary to fill the antarctic
reservoir in June and the Arctic Ocean in December, in order to
check the straightening, since otherwise it might get beyond the
perpendicular and swing the other way.  When this motion is
completely arrested, I suggest that we blow up the Aleutian Isles
and enlarge Bering Strait, so as to allow what corresponds to the
Atlantic Gulf Stream in the Pacific to enter the Arctic
Archipelago, which I have calculated will raise the average
temperature of that entire region about thirty degrees, thereby
still further increasing the amount of available land.

"Ocean currents, being the result of the prevailing winds, which
will be more regular than at present, can be counted upon to
continue practically as they are.  It may not be plain to you why
the trade winds do not blow towards the equator due south and
north, since the equator has much the same effect on air that a
stove has in the centre of a room, causing an ascending current
towards the ceiling, which moves off in straight lines in all
directions on reaching it, its place being taken by cold currents
moving in opposite directions along the floor.  Picture to
yourselves the ascending currents at the equator moving off to
the poles from which they came.  As they move north they are
continually coming to parts of the globe having smaller circles
of latitude than those they have left, and therefore not moved
forward as rapidly by the earth's daily rotation as the latitudes
nearer the equator.  The winds consequently run ahead of the
surface, and so move east of north--the earth turning towards the
east--while the heavier colder surface currents, rushing towards
the equator to take the place of the ascending column, coming
from regions where the surface whirls comparatively slowly to
those where it is rotating faster, are continually left behind,
and so move southwest; while south of the equator a corresponding
motion results.  Though this is not the most exact explanation,
it may serve to make the action clear.  I will add, that if any
one prefers a colder or a warmer climate than that of the place
in which he lives, he need only go north or south for an hour;
or, if he prefers his own latitude, he can rise a few thousand
feet in the air, or descend to one of the worked-out coal-mines
which are now used as sanitariums, and secure his object by a
slight change of altitude.  Let us speed the departure of racking
changes and extremes of climate, and prepare to welcome what we
believe prevails in paradise--namely, everlasting spring."

Appended to the address was the report of the Government
Examining Committee, which ran:  "We have critically examined the
Terrestrial Axis Straightening Company's figures and
calculations, also its statements involving natural philosophy,
physics, and astronomy, all of which we find correct, and hereby
approve.

                           CHAPTER IV.

   PROF. CORTLANDT'S HISTORICAL SKETCH OF THE WORLD

               IN A. D. 2000.


Prof. Cortlandt, preparing a history of the times at the
beginning of the great terrestrial and astronomical change, wrote
as follows:  "This period--A.D. 2000--is by far the most
wonderful the world has as yet seen.  The advance in scientific
knowledge and attainment within the memory, of the present
generation has been so stupendous that it completely overshadows
all that has preceded.  All times in history and all periods of
the world have been remarkable for some distinctive or
characteristic trait.  The feature of the period of Louis XIV was
the splendour of the court and the centralization of power in
Paris.  The year 1789 marked the decline of the power of courts
and the evolution of government by the people.  So, by the spread
of republican ideas and the great advance in science, education
has become universal, for women as well as for men, and this is
more than ever a mechanical age.

"With increased knowledge we are constantly coming to realize how
little we really know, and are also continually finding
manifestations of forces that at first seem like exceptions to
established laws.  This is, of course, brought about by the
modifying influence of some other natural law, though many of
these we have not yet discovered.

"Electricity in its varied forms does all work, having superseded
animal and manual labour in everything, and man has only to
direct.  The greatest ingenuity next to finding new uses for this
almost omnipotent fluid has been displayed in inducing the forces
of Nature, and even the sun, to produce it.  Before describing
the features of this perfection of civilization, let us review
the steps by which society and the political world reached their
present state.

"At the close of the Franco-Prussian War, in 1871, Continental
Europe entered upon the condition of an armed camp, which lasted
for nearly half a century.  The primary cause of this was the
mutual dislike and jealousy of France and Germany, each of which
strove to have a larger and better equipped national defence than
the other.  There were also many other causes, as the ambition of
the Russian Czar, supported by his country's vast though
imperfectly developed resources and practically unlimited supply
of men, one phase of which was the constant ferment in the Balkan
Peninsula, and another Russia's schemes for extension in Asia;
another was the general desire for colonies in Africa, in which
one Continental power pretty effectually blocked another, and the
latent distrust inside the Triple Alliance.  England, meanwhile,
preserved a wise and profitable neutrality.

"These tremendous sacrifices for armaments, both on land and
water, had far-reaching results, and, as we see it now, were
clouds with silver linings.  The demand for hardened steel
projectiles, nickel-steel plates, and light and almost
unbreakable machinery, was a great incentive to improvement in
metallurgy while the necessity for compact and safely carried
ammunition greatly stimulated chemical research, and led to the
discovery of explosives whose powers no obstacle can resist, and
incidentally to other more useful things.

"Further mechanical and scientific progress, however, such as
flying machines provided with these high explosives, and
asphyxiating bombs containing compressed gas that could be fired
from guns or dropped from the air, intervened.  The former would
have laid every city in the dust, and the latter might have
almost exterminated the race.  These discoveries providentially
prevented hostilities, so that the 'Great War,' so long expected,
never came, and the rival nations had their pains for nothing,
or, rather, for others than themselves.

"Let us now  examine the political and ethnological results.
Hundreds of thousands, of the flower of Continental Europe were
killed by overwork and short rations, and millions of desirable
and often--unfortunately for us--undesirable people were driven
to emigration, nearly all of whom came to English-speaking
territory, greatly increasing our productiveness and power.  As,
we have seen, the jealousy of the Continental powers for one
another effectually prevented their extending their influence or
protectorates to other continents, which jealousy was
considerably aided by the small but destructive wars that did
take place.  High taxes also made it more difficult for the
moneyed men to invest in colonizing or development companies,
which are so often the forerunners of absorption; while the
United States, with her coal--of which the Mediterranean states
have scarcely any--other resources, and low taxes, which, though
necessary, can be nothing but an evil, has been able to expand
naturally as no other nation ever has before.

"This has given the English-speakers, especially the United
States, a free hand, rendering enforcement of the Monroe doctrine
easy, and started English a long way towards becoming the
universal language, while all formerly unoccupied land is now
owned by those speaking it.

"At the close of our civil war, in 1865, we had but 3,000,000
square miles, and a population of 34,000,000.  The country
staggered beneath a colossal debt of over  $4,000,000,000, had an
expensive but essentially perishable navy, and there was an
ominous feeling between the sections.  The purchase of Alaska in
1867, by which we added over half a million square miles to our
territory, marked the resumption of the forward march of the
United States.  Twenty-five years later, at the presidential
campaign of 1892, the debt had been reduced to $900,000,000,
deducting the sinking fund, and the charge for pensions had about
reached its maximum and soon began to decrease, though no one
objected to any amount of reward for bona fide soldiers who had
helped to save the country.  The country's wealth had also
enormously increased, while the population had grown to
65,000,000.  Our ancestors had, completed or in building, a navy
of which no nation need be ashamed; and, though occasionally
marred by hard times, there was general prosperity.

"Gradually the different States of Canada--or provinces, as they
were then called--came to realize that their future would be far
grander and more glorious in union with the United States than
separated from it; and also that their sympathy was far stronger
for their nearest neighbours than for any one else.  One by one
these Northern States made known their desire for consolidation
with the Union, retaining complete control of their local
affairs, as have the older States.  They were gladly welcomed by
our Government and people, and possible rivals became the best of
friends.  Preceding and also following this, the States of
Mexico, Central America, and parts of South America, tiring of
the incessant revolutions and difficulties among themselves,
which had pretty constantly looked upon us as a big brother on
account of our maintenance of the Monroe doctrine, began to
agitate for annexation, knowing they would retain control of
their local affairs.  In this they were vigorously supported by
the American residents and property-holders, who knew that their
possessions would double in value the day the United States
Constitution was signed.

"Thus, in the first place, by the encouragement of our people,
and latterly, apparently, by its own volition, the Union has
increased enormously in power, till it now embraces 10,000,000
square miles, and has a free and enlightened population of
300,000,000.  Though the Union established by Washington and his
contemporaries has attained such tremendous proportions, its
growth is by no means finished; and as a result of modern
improvements, it is less of a journey now to go from Alaska to
the Orinoco than it was for the Father of his Country to travel
from New York or Philadelphia to the site of the city named in
his honour.


"Adequate and really rapid transportation facilities have done
much to bind the different parts of the country together, and to
rub off the edges of local prejudice.  Though we always favour
peace, no nation would think of opposing the expressed wishes of
the United States, and our moral power for good is tremendous.
The name Japhet means enlargement, and the prophecy seems about
to be literally fulfilled by these his descendants.  The bankrupt
suffering of so many European Continental powers had also other
results.  It enabled the socialists--who have never been able to
see beyond themselves--to force their governments into selling
their colonies in the Eastern hemisphere to England, and their
islands in the Western to us, in order to realize upon them.
With the addition of Canada to the United States and its loss to
the British Empire, the land possessions of the two powers became
about equal, our Union being a trifle the larger.  All danger of
war being removed by the Canadian change, a healthful and
friendly competition took its place, the nations competing in
their growth on different hemispheres.  England easily added
large areas in Asia and Africa, while the United States grew as
we have seen.  The race is still, in a sense, neck-and-neck, and
the English-speakers together possess nearly half the globe.  The
world's recent rate of progress would have been impossible
without this approximation to a universal language.  The causes
that checkmated the Continental powers have ceased to exist.
Many millions of men whose principal thought had been to destroy
other members of the race became producers, but it was then too
late, for the heavy armaments had done their work.

"Let us now glance at the times as they are, and see how the
business of life is transacted.  Manhattan Island has something
over 2,500,000 inhabitants, and is surrounded by a belt of
population, several miles wide, of 12,000,000 more, of which it
is the focus, so that the entire city contains more than
14,500,000 souls.  The several hundred square miles of land and
water forming greater New York are perfectly united by numerous
bridges, tunnels, and electric ferries, while the city's great
natural advantages have been enhanced and beautified by every
ingenious device.  No main avenue in the newer sections is less
than two hundred feet wide, containing shade and fruit trees, a
bridle-path, broad sidewalks, and open spaces for carriages and
bicycles.  Several fine diagonal streets and breathing-squares
have also been provided in the older sections, and the existing
parks have been supplemented by intermediate ones, all being
connected by parkways to form continuous chains.

"The hollow masts of our ships--to glance at another phase en
passant--carry windmills instead of sails, through which the wind
performs the work, of storing a great part of the energy required
to run them at sea, while they are discharging or loading cargo
in port; and it can, of course, work to better advantage while
they are stationary than when they are running before it.  These
turbines are made entirely of light metal, and fold when not in
use, so that only the frames are visible.  Sometimes these also
fold and are housed, or wholly disappear within the mast.
Steam-boilers are also placed at the foci of huge concave
mirrors, often a hundred feet in diameter, the required heat
being supplied by the sun, without smoke, instead of by bulky and
dirty coal.  This discovery gave commercial value to Sahara and
other tropical deserts, which are now desirable for mill-sites
and for generating power, on account of the directness with which
they receive the sun's rays and their freedom from clouds.  Mile
after mile Africa has been won for the uses of civilization, till
great stretches that were considered impassible are as productive
as gardens.  Our condensers, which compress, cool, and rarefy
air, enabling travellers to obtain water and even ice from the
atmosphere, are great aids in desert exploration, removing
absolutely the principal distress of the ancient caravan.  The
erstwhile 'Dark Continent' has a larger white population now than
North America had a hundred years ago, and has this advantage for
the future, that it contains 11,600,000 square miles, while North
America has less than 9,000,000.  Every part of the globe will
soon sustain about as large and prosperous a population as the
amount of energy it receives from the sun and other sources will
warrant; public debts and the efficiency of the governments being
the variable elements.

"The rabbits in Australia, and the far more objectionable
poisonous snakes in South America and India, have been
exterminated by the capture of a few dozen of the creatures in
the infested districts, their inoculation with the virus similar
to the murus tiphi, tuberculosis or any other contagious-germ
complaint to which the species treated was particularly
susceptible, and the release of these individuals when the
disease was seen to be taking hold.  The rabbits and serpents
released at once returned to their old haunts, carrying the
plague far and wide.  The unfortunate rabbits were greatly
commiserated even by the medicos that wielded the death-dealing
syringe; but, fortunately for themselves, they died easily.  The
reptiles, perhaps on account of the wider distribution of the
nerve centres, had more lingering but not painful deaths, often,
while in articulo mortis, leaving the holes with which they
seemed to connect their discomfort, and making a final struggle
along the ground, only to die more quickly as a result of their
exertions.  We have applied this also to the potato-bug, locust,
and other insect pests, no victim being too small for the
ubiquitous, subtle germ, which, properly cultivated and utilized,
has become one of man's best friends.

"We have microbe tests that show us as unmistakably whether the
germs of any particular disease--like malaria, typhoid, or
scarlet fever--are present in the air, as litmus-paper shows
alkalinity of a solution.  We also inoculate as a preventive
against these and almost all other germ diseases, with the same
success that we vaccinate for smallpox.

"The medicinal properties of all articles of food are so well
understood also, that most cures are brought about simply by
dieting.  This, reminds me of the mistakes perpetrated on a
friend of mine who called in Dr. Grave-Powders, one of the
old-school physicians, to be treated for insomnia and dyspepsia.
This old numskull restricted his diet, gave him huge doses of
medicine, and decided most learnedly that he was daily growing
worse.  Concluding that he had but a short time to live, my
friend threw away the nauseating medicines, ate whatever he had a
natural desire for, and was soon as well as ever--the obvious
moral of which is, that we can get whatever treatment we need
most beneficially from our food.  Our physicians are most serious
and thoughtful men.  They never claim to be infallible, but study
scientifically to increase their knowledge and improve the
methods of treatment.  As a result of this, fresh air, regular
exercise for both sexes, with better conditions, and the
preservation of the lives of children that formerly died by
thousands from preventable causes, the physique, especially of
women, is wonderfully improved, and the average longevity is
already over sixty.

"Our social structure, to be brief, is based on science, or the
conservation of energy, as the Greek philosophers predicted.  It
was known to them that a certain amount of power would produce
only a certain amount of work--that is, the weight of a clock in
descending or a spring in uncoiling returns theoretically the
amount of work expended in raising or coiling it, and in no
possible way can it do more.  In practice, on account of
friction, etc., we know it does less.  This law, being
invariable, of course limits us, as it did Archimedes and
Pythagoras; we have simply utilized sources of power that their
clumsy workmen allowed to escape.  Of the four principal
sources--food, fuel, wind, and tide--including harnessed
waterfalls, the last two do by far the most work.  Much of the
electrical energy in every thunderstorm is also captured and
condensed in our capacious storage batteries, as natural hygeia
in the form of rain was and is still caught in our country
cisterns.  Every exposed place is crowned by a cluster of huge
windmills that lift water to some pond or reservoir placed as
high as possible.  Every stiff breeze, therefore, raises millions
of tons of water which  operate hydraulic turbines as required.
Incidentally these storage reservoirs, by increasing the surface
exposed to evaporation and the consequent rainfall, have a very
beneficial effect on the dry regions in the interior of the
continent, and in some cases have almost superseded irrigation.
The windmill and dynamo thus utilize bleak mountain-tops that,
till their discovery, seemed to be but indifferent successes in
Dame Nature's domain.  The electricity generated by these, in
connection with that obtained by waterfalls, tidal dynamos,
thunderstorms, chemical action, and slow-moving
quadruple-expansion steam engines, provides the power required to
run our electric ships and water-spiders, railways, and
stationary and portable motors, for heating the cables laid along
the bottom of our canals to prevent their freezing in winter, and
for almost every conceivable purpose.  Sometimes a man has a
windmill on his roof for light and heat; then, the harder the
wintry blasts may blow the brighter and warmer becomes the house,
the current passing through a storage battery to make it more
steady.  The operation of our ordinary electric railways is very
simple: the current is taken from an overhead, side, or
underneath wire, directly through the air, without the
intervention of a trolley, and the fast cars, for they are no
longer run in trains, make five miles a minute.  The entire
weight of each car being used for its own traction, it can ascend
very steep grades, and can attain high speed or stop very
quickly.

"Another form is the magnetic railway, on which the cars are
wedge-shaped at both ends, and moved by huge magnets weighing
four thousand tons each, placed fifty miles apart.  On passing a
magnet, the nature of the electricity charging a car is
automatically changed from positive to negative, or vice versa,
to that of the magnet just passed, so that it repels while the
next attracts.  The successive magnets are charged oppositely,
the sections being divided halfway between by insulators, the
nature of the electricity in each section being governed by the
charge in the magnet.  To prevent one kind of electricity from
uniting with and neutralizing that in the next section by passing
through the car at the moment of transit, there is a "dead
stretch" of fifty yards with rails not charged at all between the
sections.  This change in the nature of the electricity is
repeated automatically every fifty miles, and obviates the
necessity of revolving machinery, the rails aiding communication.

"Magnetism being practically as instantaneous as gravitation, the
only limitations to speed are the electrical pressure at the
magnets, the resistance of the air, and the danger of the wheels
bursting from centrifugal force.  The first can seemingly be
increased without limit; the atmospheric resistance is about to
be reduced by running the cars hermetically sealed through a
partial vacuum in a steel and toughened glass tube; while the
third has been removed indefinitely by the use of galvanized
aluminum, which bears about the same relation to ordinary
aluminum that steel does to iron, and which has twice the tensile
strength and but one third the weight of steel.  In some cases
the rails are made turned in, so that it would be impossible for
a car to leave the track without the road-bed's being totally
demolished; but in most cases this is found to be unnecessary,
for no through line has a curve on its vast stretches with a
radius of less than half a mile.  Rails, one hundred and sixty
pounds to the yard, are set in grooved steel ties, which in turn
are held by a concrete road-bed consisting of broken stone and
cement, making spreading rails and loose ballast impossible.  A
large increase in capital was necessary for these improvements,
the elimination of curves being the most laborious part,
requiring bridges, cuttings, and embankments that dwarf the
Pyramids and would have made the ancient Pharaohs open their
eyes; but with the low rate of interest on bonds, the slight cost
of power, and great increase in business, the venture was a
success, and we are now in sight of further advances that will
enable a traveller in a high latitude moving west to keep pace
with the sun, and, should he wish it, to have unending day."



                           CHAPTER V.

               DR. CORTLANDT'S HISTORY CONTINUED.

"In marine transportation we have two methods, one for freight
and another for passengers.  The old-fashioned deeply immersed
ship has not changed radically from the steam and sailing vessels
of the last century, except that electricity has superseded all
other motive powers.  Steamers gradually passed through the five
hundred-, six hundred-, and seven hundred-foot-long class, with
other dimensions in proportion, till their length exceeded one
thousand feet.  These were very fast ships, crossing the Atlantic
in four and a half days, and were almost as steady as houses, in
even the roughest weather.

"Ships at this period of their development had also passed
through the twin and triple screw stage to the quadruple, all
four together developing one hundred and forty thousand indicated
horse-power, and being driven by steam.  This, of course,
involved sacrificing the best part of the ship to her engines,
and a very heavy idle investment while in port.  Storage
batteries, with plates composed of lead or iron, constantly
increasing in size, had reached a fair state of development by
the close of the nineteenth century.

"During the second decade of the twentieth century the engineers
decided to try the plan of running half of a transatlantic
liner's screws by electricity generated by the engines for
driving the others while the ship was in port, this having been a
success already on a smaller scale.  For a time this plan gave
great satisfaction, since it diminished the amount of coal to be
carried and the consequent change of displacement at sea, and
enabled the ship to be worked with a smaller number of men.  The
batteries could also, of course, be distributed along the entire
length, and placed where space was least valuable.

"The construction of such huge vessels called for much
governmental river and harbour dredging, and a ship drawing
thirty-five feet can now enter New York at any state of the tide.
For ocean bars, the old system of taking the material out to sea
and discharging it still survives, though a jet of water from
force-pumps directed against the obstruction is also often
employed with quick results.  For river work we have discovered a
better method.  All the mud is run back, sometimes over a mile
from the river bank, where it is used as a fertilizer, by means
of wire railways strung from poles.  These wire cables combine in
themselves the functions of trolley wire and steel rail, and
carry the suspended cars, which empty themselves and return
around the loop for another load.  Often the removed material
entirely fills small, saucer-shaped valleys or low places, in
which case it cannot wash back.  This improvement has ended the
necessity of building jetties.

"The next improvement in sea travelling was the 'marine spider.'
As the name shows, this is built on the principle of an insect.
It is well known that a body can be carried over the water much
faster than through it.  With this in mind, builders at first
constructed light framework decks on large water-tight wheels or
drums, having paddles on their circumferences to provide a hold
on the water.  These they caused to revolve by means of machinery
on the deck, but soon found that the resistance offered to the
barrel wheels themselves was too great.  They therefore made them
more like centipeds with large, bell-shaped feet, connected with
a superstructural deck by ankle-jointed pipes, through which,
when necessary, a pressure of air can be forced down upon the
enclosed surface of water.  Ordinarily, however, they go at great
speed without this, the weight of the water displaced by the bell
feet being as great as that resting upon them.  Thus they swing
along like a pacing horse, except that there are four rows of
feet instead of two, each foot being taken out of the water as it
is swung forward, the first and fourth and second and third rows
being worked together.  Although, on account of their size, which
covers several acres, they can go in any water, they give the
best results on Mediterraneans and lakes that are free from ocean
rollers, and, under favourable conditions, make better speed than
the nineteenth-century express trains, and, of course, going
straight as the crow flies, and without stopping, they reach a
destination in considerably shorter time.

Some passengers and express packages still cross the Atlantic on
'spiders,' but most of these light cargoes go in a far pleasanter
and more rapid way.  The deep-displacement vessels, for heavy
freight, make little better speed than was made by the same class
a hundred years ago.  But they are also run entirely by
electricity, largely supplied by wind, and by the tide turning
their motors, which become dynamos while at anchor in any stream.
They therefore need no bulky boilers, engines, sails, or
coal-bunkers, and consequently can carry unprecedentedly large
cargoes with comparatively small crews.  The officers on the
bridge and the men in the crow's nest--the way to which is by a
ladder INSIDE the mast, to protect the climber from the
weather--are about all that is needed; while disablement is made
practically impossible, by having four screws, each with its own
set of automatically lubricating motors.

"This change, like other labour-saving appliances, at first
resulted in laying off a good many men, the least satisfactory
being the first to go; but the increase in business was so great
that the intelligent men were soon reemployed as officers at
higher rates of pay and more interesting work than before, while
they as consumers were benefited as much as any one else by the
decreased cost of production and transportation.

"With a view to facilitating interchange still further, our
Government has gradually completed the double coast-line that
Nature gave us in part.  This was done by connecting islands
separated from shore by navigable water, and leaving openings for
ingress and exit but a few hundred yards wide.  The breakwaters
required to do this were built with cribbing of incorrodible
metal, affixed to deeply driven metallic piles, and filled with
stones along coasts where they were found in abundance or excess.
This, while clearing many fields and improving them for
cultivation, provided just the needed material; since irregular
stones bind together firmly, and, while also insoluble, combine
considerable bulk with weight.  South of Hatteras, where stones
are scarce, the sand dredged from parts of the channel was filled
into the crib, the surface of which has a concave metallic cover,
a trough of still water being often the best barrier against the
passage of waves.  This double coast-line has been a great
benefit, and propelled vessels of moderate draught can range in
smooth water, carrying very full loads, from Labrador to the
Orinoco.  The exits are, of course, protected by a line of
cribbing a few hundred feet to seaward.

"The rocks have been removed from all channels about New York and
other commercial centres, while the shallow places have been
dredged to a uniform depth.  This diminishes the dangers of
navigation and considerably decreases the speed with which the
tides rush through.  Where the obstructions consisted of reefs
surrounded by deep water, their removal with explosives was easy,
the shattered fragments being allowed to sink to the bottom and
remain there beneath the danger line.

"Many other great works have also been completed.  The canals at
Nicaragua have been in operation many years, it having been found
best to have several sizes of locks, and to use the large ones
only for the passage of large vessels.  The improved Erie and
Champlain Canals also enable ships four hundred feet long to
reach New York from the Great Lakes via the Hudson River.

"For flying, we have an aeroplane that came in when we devised a
suitable motor power.  This is obtained from very light
paper-cell batteries that combine some qualities of the primary
and secondary type, since they must first be charged from a
dynamo, after which they can supply full currents for one hundred
hours--enough to take them around the globe--while partly
consuming the elements in the cells.  The power is applied
through turbine screws, half of which are capable of propelling
the flat deck in its inclined position at sufficient speed to
prevent its falling.  The moving parts have ball bearings and
friction rollers, lubrication being secured automatically, when
required, by a supply of vaseline that melts if any part becomes
hot.  All the framing is of thin but very durable galvanized
aluminum, which has superseded steel for every purpose in which
weight is not an advantage, as in the permanent way on railways.
The air ships, whose length varies from fifty to five hundred
feet, have rudders for giving a vertical or a horizontal motion,
and several strengthening keels that prevent leeway when turning.
They are entirely on the principle of birds, maintaining
themselves mechanically, and differing thus from the unwieldy
balloon.  Starting as if on a circular railway, against the wind,
they rise to a considerable height, and then, shutting off the
batteries, coast down the aerial slope at a rate that sometimes
touches five hundred miles an hour.  When near the ground the
helmsman directs the prow upward, and, again turning on full
current, rushes up the slope at a speed that far exceeds the
eagle's, each drop of two miles serving to take the machine
twenty or thirty; though, if the pilot does not wish to soar, or
if there is a fair wind at a given height, he can remain in that
stratum of the atmosphere by moving horizontally.  He can also
maintain his elevation when moving very slowly, and though the
headway be entirely stopped, the descent is gradual on account of
the aeroplane's great spread, the batteries and motors being
secured to the under side of the deck.

"The motors are so light that they develop two horse power for
every pound of their weight; while, to keep the frames thin, the
necessary power is obtained by terrific speed of the moving
parts, as though a steam engine, to avoid great pressure in its
cylinders, had a long stroke and ran at great piston speed,
which, however, is no disadvantage to the rotary motion of the
electric motor, there being no reciprocating cranks, etc., that
must be started and stopped at each revolution.

"To obviate the necessity of gearing to reduce the number of
revolutions to those possible for a large screw, this member is
made very small, and allowed to revolve three thousand times a
minute, so that the requisite power is obtained with great
simplicity of mechanism, which further decreases friction.  The
shafts, and even the wires connecting the batteries with the
motors, are made large and hollow.  Though the primary battery
pure and simple, as the result of great recent advances in
chemistry, seems to be again coming up, the best aeroplane
batteries are still of the combination- storage type.  These have
been so perfected that eight ounces of battery yield one horse
power for six hours, so that two pounds of battery will supply a
horse power for twenty-four hours; a small fifty-horse-power
aeroplane being therefore able to fly four days with a battery
weight of but four hundred pounds.

"Limestone and clarified acid are the principal parts of these
batteries.  It was known long ago that there was about as much
imprisoned solar energy in limestone as in coal, but it was only
recently that we discovered this way of releasing and using it.

"Common salt plays an important part in many of our chemical
reactions.  By combining it with limestone, and treating this
with acid jelly, we also get good results on raising to the
boiling-point.

"However enjoyable the manly sport of yachting is on water, how
vastly more interesting and fascinating it is for a man to have a
yacht in which he can fly to Europe in one day, and with which
the exploration of tropical Africa or the regions about the poles
is mere child's play, while giving him so magnificent a
bird's-eye view!  Many seemingly insoluble problems are solved by
the advent of these birds.  Having as their halo the enforcement
of peace, they have in truth taken us a long step towards heaven,
and to the co-operation and higher civilization that followed we
shall owe much of the success of the great experiment on Mother
Earth now about to be tried.

"Another change that came in with a rush upon the discovery of a
battery with insignificant weight, compact form, and great
capacity, was the substitution of electricity for animal power
for the movement of all vehicles.  This, of necessity brought in
good roads, the results obtainable on such being so much greater
than on bad ones that a universal demand for them arose.  This
was in a sense cumulative, since the better the streets and roads
became, the greater the inducement to have an electric carriage.
The work of opening up the country far and near, by straightening
and improving existing roads, and laying out new ones that
combine the solidity of the Appian Way with the smoothness of
modern asphalt, was largely done by convicts, working under the
direction of State and Government engineers.  Every State
contained a horde of these unprofitable boarders, who, as they
formerly worked, interfered with honest labour, and when idle got
into trouble.  City streets had been paved by the municipality;
country roads attended to by the farmers, usually very
unscientifically.  Here was a field in which convict labour would
not compete, and an important work could be done.  When once this
was made the law, every year showed improvement, while the
convicts had useful and healthful occupation.

"The electric phaetons, as those for high speed are called, have
three and four wheels, and weigh, including battery and motor,
five hundred to four thousand pounds.  With hollow but immensely
strong galvanically treated aluminum frames and pneumatic or
cushion tires, they run at thirty-five and forty miles an hour on
country roads, and attain a speed over forty on city streets, and
can maintain this rate without recharging for several days.  They
can therefore roam over the roads of the entire hemisphere, from
the fertile valley of the Peace and grey shores of Hudson Bay, to
beautiful Lake Nicaragua, the River Plate, and Patagonia,
improving man by bringing him close to Nature, while they combine
the sensations of coasting with the interest of seeing the
country well.

"To recharge the batteries, which can be done in almost every
town and village, two copper pins attached to insulated copper
wires are shoved into smooth-bored holes.  These drop out of
themselves by fusing a small lead ribbon, owing to the increased
resistance, when the acid in the batteries begins to 'boil,'
though there is, of course, but little heat in this, the function
of charging being merely to bring about the condition in which
part of the limestone can be consumed, the batteries themselves,
when in constant use, requiring to be renewed about once a month.
A handle at the box seat turns on any part of the attainable
current, for either going ahead or reversing, there being six or
eight degrees of speed for both directions, while the steering is
done with a small wheel.

"Light but powerful batteries and motors have also been fitted on
bicycles, which can act either as auxiliaries for hill-climbing
or in case of head wind, or they can propel the machine
altogether.

"Gradually the width of the streets became insufficient for the
traffic, although the elimination of horses and the consequent
increase in speed greatly augmented their carrying capacity,
until recently a new system came in.  The whole width of the
avenues and streets in the business parts of the city, including
the former sidewalks, is given up to wheel traffic, an iron ridge
extending along the exact centre to compel vehicles to keep to
the right.  Strips of nickel painted white, and showing a bright
phosphorescence at night, are let into the metal pavement flush
with the surface, and run parallel to this ridge at distances of
ten to fifteen feet, dividing each half of the avenue into four
or five sections, their width increasing as they approach the
middle.  All trucks or drays moving at less than seven miles an
hour are obliged to keep in the section nearest the building
line, those running between seven and fifteen in the next,
fifteen to twenty-five in the third, twenty-five to thirty-five
in the fourth, and everything faster than that in the section
next the ridge, unless the avenue or street is wide enough for
further subdivisions.  If it is wide enough for only four or
less, the fastest vehicles must keep next the middle, and limit
their speed to the rate allowed in that section, which is marked
at every crossing in white letters sufficiently large for him
that runs to read.  It is therefore only in the wide
thoroughfares that very high speed can be attained.  In addition
to the crank that corresponds to a throttle, there is a gauge on
every vehicle, which shows its exact speed in miles per hour, by
gearing operated by the revolutions of the wheels.

"The policemen on duty also have instantaneous kodaks mounted on
tripods, which show the position of any carriage at half- and
quarter-second intervals, by which it is easy to ascertain the
exact speed, should the officers be unable to judge it by the
eye; so there is no danger of a vehicle's speed exceeding that
allowed in the section in which it happens to be; neither can a
slow one remain on the fast lines.

"Of course, to make such high speed for ordinary carriages
possible, a perfect pavement became a sine qua non.  We have
secured this by the half-inch sheet of steel spread over a
carefully laid surface of asphalt, with but little bevel; and
though this might be slippery for horses' feet, it never
seriously affects our wheels.  There being nothing harder than
the rubber ties of comparatively light drays upon it--for the
heavy traffic is carried by electric railways under ground--it
will practically never wear out.

"With the application of steel to the entire surface, car-tracks
became unnecessary, ordinary wheels answering as well as those
with flanges, so that no new tracks were laid, and finally the
car companies tore up the existing ones, selling them in many
instances to the municipalities as old iron.  Our streets also
need but little cleaning; neither is the surface continually
indented, as the old cobble-stones and Belgian blocks were, by
the pounding of the horses' feet, so that the substitution of
electricity for animal power has done much to solve the problem
of attractive streets.

"Scarcely a ton of coal comes to Manhattan Island or its vicinity
in a year.  Very little of it leaves the mines, at the mouths of
which it is converted into electricity and sent to the points of
consumption by wire, where it is employed for all uses to which
fuel was put, and many others.  Consequently there is no smoke,
and the streets are not encumbered with coal-carts; the entire
width being given up to carriages, etc.  The ground floors in the
business parts are used for large warehouses, trucks running in
to load and unload.  Pedestrians therefore have sidewalks level
with the second story, consisting of glass floors let into
aluminum frames, while all street crossings are made on bridges.
Private houses have a front door opening on the  sidewalk, and
another on the ground level, so that ladies paying visits or
leaving cards can do so in carriages.  In business streets the
second story is used for shops.  In place of steel covering,
country roads have a thick coating of cement and asphalt over a
foundation of crushed stone, giving a capital surface, and have a
width of thirty-three feet (two rods) in thinly settled
districts, to sixty-six feet (four rods) where the population is
greater.  All are planted with shade and fruit trees, while the
wide driveways have one or two broad sidewalks.  The same rule of
making the slow-moving vehicles keep near the outside prevails,
though the rate of increase in speed on approaching the middle is
more rapid than in cities, and there is usually no dividing
ridge.  On reaching the top of a long and steep hill, if we do
not wish to coast, we convert the motors into dynamos, while
running at full speed, and so change the kinetic energy of the
descent into potential in our batteries.  This twentieth-century
stage-coaching is one of the delights to which we are heirs,
though horses are still used by those that prefer them.

We have been much aided in our material progress by the facility
with which we obtain the metals.  It was observed, some time ago,
that when artesian and oil wells had reached a considerable
depth, what appeared to be drops of lead and antimony came up
with the stream.  It finally occurred to a well-borer that if he
could make his drill hard enough and get it down far enough,
keeping it cool by solidified carbonic acid during the
proceeding, he would reach a point at which most of the metals
would be viscous, if not actually molten, and on being freed from
the pressure of the crust they would expand, and reach the
surface in a stream.  This experiment he performed near the hot
geysers in Yellowstone Park, and what was his delight, on
reaching a depth scarcely half a mile beyond his usual stopping-
place, to be rewarded by a stream of metal that heralded its
approach by a loud explosion and a great rush of superheated
steam!  It ran for a month, completely filling the bed of a
small, dried-up river, and when it did stop there were ten
million tons in sight.  This proved the feasibility of the
scheme, and, though many subsequent attempts were less
successful, we have learned by experience where it is best to
drill, and can now obtain almost any metal we wish.

"'Magnetic eyes' are of great use to miners and Civil engineers.
These instruments are something like the mariner's compass, with
the sensitiveness enormously increased by galvanic currents.  The
'eye,' as it were, sees what substances are underground, and at
what distances.  It also shows how many people are in an
adjoining room--through the magnetic properties of the iron in
their blood--whether they are moving, and in what directions and
at what speed they go.  In connection with the phonograph and
concealed by draperies, it is useful to detectives, who, through
a registering attachment, can obtain a record of everything said
and done.

"Our political system remains with but little change.  Each State
has still two United States Senators, though the population
represented by each representative has been greatly increased, so
that the Senate has grown numerically much more than the House.
It is the duty of each member of Congress to understand the
conditions existing in every other member's State or district,
and the country's interest always precedes that of party.  We
have a comprehensive examination system in the civil service, and
every officeholder, except members of the Cabinet, retains his
office while efficiently performing his duty, without regard to
politics.  The President can also be re-elected any number of
times.  The Cabinet members, as formerly, usually remain in
office while he does, and appear regularly in Congress to defend
their measures.

"The really rapid transit lines in New York are underground, and
have six tracks, two being used for freight.  At all stations the
local tracks rise several feet towards the street and slope off
in both directions, while the express tracks do this only at
stations at which the faster trains stop.  This gives the
passengers a shorter distance to descend or rise in the
elevators, and the ascent before the stations aids the brakes in
stopping, while the drop helps the motors to start the trains
quickly in getting away.

"Photography has also made great strides, and there is now no
difficulty in reproducing exactly the colours of the object
taken.

"Telephones have been so improved that one person can speak in
his natural voice with another in any part of the globe, the wire
that enables him to hear also showing him the face of the speaker
though he be at the antipodes.  All telephone wires being
underground and kept by themselves, they are not interfered with
by any high-tension electric-light or power wires, thunderstorms,
or anything else.

"Rain-making is another subject removed from the uncertainties,
and has become an absolute science.  We produce clouds by
explosions in the atmosphere's heights and by surface air forced
by blowers through large pipes up the side of a mountain or
natural elevation and there discharged through an opening in the
top of a tower built on the highest part.  The aeriduct is
incased in a poor heat-conductor, so that the air retains its
warmth until discharged, when it is cooled by expansion and the
surrounding cold air.  Condensation takes place and soon serves
to start a rain.

"Yet, until the earth's axis is straightened, we must be more or
less dependent on the eccentricities of the weather, with
extremes of heat and cold, droughts and floods, which last are of
course largely the result of several months' moisture held on the
ground in the form of snow, the congestion being relieved
suddenly by the warm spring rains.

"Medicine and surgery have kept pace with other
improvements--inoculation and antiseptics, as already seen,
rendering most of the germ diseases and formerly dreaded
epidemics impotent; while through the potency of electrical
affinity we form wholesome food-products rapidly, instead of
having to wait for their production by Nature's slow processes.

"The metric system, now universal, superseded the old-fashioned
arbitrary standards, so prolific of mistakes and confusion, about
a century ago.

"English, as we have seen, is already the language of 600,000,000
people, and the number is constantly increasing through its
adoption by the numerous races of India, where, even before the
close of the last century, it was about as important as Latin
during the greatness of Rome, and by the fact that the Spanish
and Portuguese elements in Mexico and Central and South America
show a constant tendency to die out, much as the population of
Spain fell from 30,000,000 to 17,000,000 during the nineteenth
century.  As this goes on, in the Western hemisphere, the places
left vacant are gradually filled by the more progressive
Anglo-Saxons, so that it looks as if the study of ethnology in
the future would be very simple.

"The people with cultivation and leisure, whose number is
increasing relatively to the population at each generation, spend
much more of their year in the country than formerly, where they
have large and well-cultivated country seats, parts of which are
also preserved for game.  This growing custom on the part of
society, in addition to being of great advantage to the
out-of-town districts, has done much to save the forests and
preserve some forms of game that would otherwise, like the
buffalo, have become extinct.

"In astronomy we have also made tremendous strides.  The
old-fashioned double-convex lens used in telescopes became so
heavy as its size grew, that it bent perceptibly from its own
weight, when pointed at the zenith, distorting the vision; while
when it was used upon a star near the horizon, though the glass
on edge kept its shape, there was too much atmosphere between it
and the observed object for successful study.  Our recent
telescopes have, therefore, concave plate-glass mirrors, twenty
metres in diameter, like those used for converging the sun's rays
in solar engines, but with curves more mathematically exact,
which collect an immense amount of light and focus it on a
sensitive plate or on the eye of the observer, whose back is
turned to the object he is studying.  An electrical field also
plays an important part, the electricity being as great an aid to
light as in the telephone it is to sound.  With these placed
generally on high mountain peaks, beyond the reach of clouds, we
have enormously increased the number of visible stars, though
there are still probably boundless regions that we cannot see.
These telescopes have several hundred times the power of the
largest lenses of the nineteenth century, and apparently bring
Mars and Jupiter, when in opposition, within one thousand and ten
thousand miles, respectively, so that we study their physical
geography and topography; and we have good maps of Jupiter, and
even of Saturn, notwithstanding their distance and atmospheric
envelopes, and we are able to see the disks of third-magnitude
stars.

"It seems as if, when we wish any particular discovery or
invention, in whatever field, we had but to turn our efforts in
its direction to obtain our desire.  We seem, in fact, to have
awakened in the scenes of the Arabian Nights; yet the mysterious
genius which we control, and which dims Aladdin's lamp, is the
gift of no fairy godmother sustained by the haze of dreams, but
shines as the child of science with fadeless and growing
splendour, and may yet bring us and our little planet much closer
to God.

"We should indeed be happy, living as we do at this apex of
attained civilization, with the boundless possibilities of the
future unfolding before us, on the horizon of which we may fairly
be said to stand.

"We are freed from the rattling granite pavement of only a
century ago, which made the occupant of an omnibus feel like a
fly inside of a drum; from the domination of our local politics
by ignorant foreigners; and from country roads that either filled
the eyes, lungs, and hair of the unfortunates travelling upon
them with dust, or, resembling ploughed and fertilized fields,
saturated and plastered them with mud.  These miseries, together
with sea-sickness in ocean travelling, are forever passed, and we
feel that 'Excelsior!' is indeed our motto.  Our new and
increasing sources of power have so stimulated production and
manufacturing that poverty or want is scarcely known; while the
development of the popular demand, as a result of the supplied
need, is so great that there is no visible limit to the
diversification of industry or the possibilities of the arts.

"It may seem strange to some that apparently so disproportionate
a number of inventions have been made in the last century.  There
are several reasons.  Since every discovery or advance in
knowledge increases our chance of obtaining more, it becomes
cumulative, and our progress is in geometric instead of
arithmetical ratio.  Public interest and general appreciation of
the value of time have also effectively assisted progress.  At
the beginning of each year the President, the Governors of the
States, and the Mayors of cities publish a prospectus of the
great improvements needed, contemplated, and under way within
their jurisdiction--it may be planning a new boulevard, a new
park, or an improved system of sewers; and at the year's end they
issue a resume of everything completed, and the progress in
everything else; and though there is usually a great difference
between the results hoped for and those attained, the effect is
good.  The newspapers publish at length the recommendations of
the Executives, and also the results obtained, and keep up public
interest in all important matters.

"Free to delve in the allurement and fascination of science,
emancipated man goes on subduing Nature, as his Maker said he
should, and turning her giant forces to his service in his
constant struggle to rise and become more like Him who gave the
commandments and showed him how he should go.

"Notwithstanding our strides in material progress,  we are not
entirely content.  As the requirements of the animal become fully
supplied, we feel a need for something else.  Some say this is
like a child that cries for the moon, but others believe it the
awakening and craving of our souls.  The historian narrates but
the signs of the times, and strives to efface himself; yet there
is clearly a void, becoming yearly more apparent, which
materialism cannot fill.  Is it some new subtle force for which
we sigh, or would we commune with spirits?  There is, so far as
we can see, no limit to our journey, and I will add, in closing,
that, with the exception of religion, we have most to hope from
science."


                           CHAPTER VI.

                       FAR-REACHING PLANS.

Knowing that the rectification of the earth's axis was
satisfactorily begun, and that each year would show an increasing
improvement in climate, many of the delegates, after hearing
Bearwarden's speech, set out for their homes.  Those from the
valley of the Amazon and the eastern coast of South America
boarded a lightning express that rushed them to Key West at the
rate of three hundred miles an hour.  The railroad had six
tracks, two for through passengers, two for locals, and two for
freight.  There they took a "water-spider," six hundred feet long
by three hundred in width, the deck of which was one hundred feet
above the surface, which carried them over the water at the rate
of a mile a minute, around the eastern end of Cuba, through
Windward Passage, and so to the South American mainland, where
they continued their journey by rail.

The Siberian and Russian delegates, who, of course, felt a keen
interest in the company's proceedings, took a magnetic
double-ender car to Bering Strait.  It was eighteen feet high,
one hundred and fifty feet long, and had two stories.  The upper,
with a toughened glass dome running the entire length, descended
to within three feet of the floor, and afforded an unobstructed
view of the rushing scenery.  The rails on which it ran were ten
feet apart, the wheels being beyond the sides, like those of a
carriage, and fitted with ball bearings to ridged axles.  The
car's flexibility allowed it to follow slight irregularities in
the track, while the free, independent wheels gave it a great
advantage in rounding curves over cars with wheels and axle in
one casting, in which one must slip while traversing a greater or
smaller arc than the other, except when the slope of the tread
and the centrifugal force happen to correspond exactly.  The fact
of having its supports outside instead of underneath, while
increasing its stability, also enabled the lower floor to come
much nearer the ground, while still the wheels were large.
Arriving in just twenty hours, they ran across on an electric
ferry-boat, capable of carrying several dozen cars, to East Cape,
Siberia, and then, by running as far north as possible, had a
short cut to Europe.

The Patagonians went by the all-rail Intercontinental Line,
without change of cars, making the run of ten thousand miles in
forty hours.  The Australians entered a flying machine, and were
soon out of sight; while the Central Americans and members from
other States of the Union returned for the most part in their
mechanical phaetons.

"A prospective improvement in travelling," said Bearwarden, as he
and his friends watched the crowd disperse, "will be when we can
rise beyond the limits of the atmosphere, wait till the earth
revolves beneath us, and descend in twelve hours on the other
side."

"True," said Cortlandt, "but then we can travel westward only,
and shall have to make a complete circuit when we wish to go
east."

A few days later there was a knock at President Bearwarden's
door, while he was seated at his desk looking over some papers
and other matters.  Taking his foot from a partly opened desk
drawer where it had been resting, he placed it upon the handle of
a handsome brass-mounted bellows, which proved to be
articulating, for, as he pressed, it called lustily, "Come in!"
The door opened, and in walked Secretary of State Stillman,
Secretary of the Navy Deepwaters, who was himself an old sailor,
Dr. Cortlandt, Ayrault.  Vice-President Dumby, of the T. A. S.
Co., and two of the company's directors.

"Good-morning," said Bearwarden, as he shook hands with his
visitors.  "Charmed to see you."

"That's a great invention," said Secretary Stillman, examining
the bellows.  "We must get Congress to make an appropriation for
its introduction in the department buildings in Washington.  You
have no idea how it dries my throat to be all the time shouting,
'Come in!'"

"Do you know, Bearwarden," said Secretary Deepwaters, "I'm afraid
when we have this millennium of climate every one will be so well
satisfied that our friend here (pointing to Secretary Stillman
with his thumb) will have nothing to do."

"I have sometimes thought some of the excitement will be gone,
and the struggle of the 'survival of the fittest' will become
less problematical," said Bearwarden.

"The earth seems destined to have a calm old age," said
Cortlandt, "unless we can look to the Cabinet to prevent it."

"This world will soon be a dull place.  I wish we could leave it
for a change," said Ayrault.  "I don't mean forever, of course,
but just as people have grown tired of remaining like plants in
the places in which they grew.  Alan has been a caterpillar for
untold ages; can he not become the butterfly?"

"Since we have found out how to straighten the axis," said
Deepwaters, "might we not go one better, and improve the orbit as
well?--increase the difference between aphelion and perihelion,
and give those that still like a changing climate a chance, while
incidentally we should see more of the world--I mean the solar
system--and, by enlarging the parallax, be able to measure the
distance of a greater number of fixed stars.  Put your helm hard
down and shout 'Hard-a-lee!'  You see, there is nothing simpler.
You keep her off now, and six months hence you let her luff."

"That's an idea!" said Bearwarden.  "Our orbit could be enough
like that of a comet to cross the orbits of both Venus and Mars;
and the climatic extremes would not be inconvenient.  The whole
earth being simultaneously warmed or cooled, there would be no
equinoctials or storms resulting from changes on one part of the
surface from intense heat to intense cold; every part would have
a twelve-hour day and night, and none would be turned towards or
from the sun for six months at a time; for, however eccentric the
orbit, we should keep the axis absolutely straight.  At
perihelion there would simply be increased evaporation and clouds
near the equator, which would shield those regions from the sun,
only to disappear again as the earth receded.

"The only trouble," said Cortlandt, "is that we should have no
fulcrum.  Straightening the axis is simple enough, for we have
the attraction of the sun with which to work, and we have but to
increase it at one end while decreasing it at the other, and
change this as the poles change their inclination towards the
sun, to bring it about.  If a comet with a sufficiently large
head would but come along and retard us, or opportunely give us a
pull, or if we could increase the attraction of the other planets
for us, or decrease it at times, it might be done.  If the force,
the control of which was discovered too late to help us
straighten the axis, could be applied on a sufficiently large
scale; if apergy----"

"I have it!" exclaimed Ayrault, jumping up.  "Apergy will do it.
We can build an airtight projectile, hermetically seal ourselves
within, and charge it in such a way that it will be repelled by
the magnetism of the earth, and it will be forced from it with
equal or greater violence than that with which it is ordinarily
attracted.  I believe the earth has but the same relation to
space that the individual molecule has to any solid, liquid, or
gaseous matter we know; and that, just as molecules strive to fly
apart on the application of heat, this earth will repel that
projectile when electricity, which we are coming to look upon as
another form of heat, is properly applied.  It must be so, and it
is the manifest destiny of the race to improve it.  Man is a
spirit cursed with a mortal body, which glues him to the earth,
and his yearning to rise, which is innate, is, I believe, only a
part of his probation and trial."

"Show us how it can be done," shouted his listeners in chorus.

"Apergy is and must be able to do it," Ayrault continued.
"Throughout Nature we find a system of compensation.  The
centripetal force is offset by the centrifugal; and when,
according to the fable, the crystal complained of its hard lot in
being unable to move, while the eagle could soar through the
upper air and see all the glories of the world, the bird replied,
'My life is but for a moment, while you, set in the rock, will
live forever, and will see the last sunrise that flashes upon the
earth.'

"We know that Christ, while walking on the waves, did not sink,
and that he and Elijah were carried up into heaven.  What became
of their material bodies we cannot  tell, but they were certainly
superior to the force of gravitation.  We have no reason to
believe that in miracles any natural law was broken, or even set
aside, but simply that some other law, whose workings we do not
understand, became operative and modified the law that otherwise
would have had things its own way.  In apergy we undoubtedly have
the counterpart of gravitation, which must exist, or Nature's
system of compensation is broken.  May we not believe that in
Christ's transfiguration on the mount, and in the appearance of
Moses and Elias with him--doubtless in the flesh, since otherwise
mortal eyes could not have seen them--apergy came into play and
upheld them; that otherwise, and if no other modification had
intervened, they would have fallen to the ground; and that apergy
was, in other words, the working principle of those miracles?"

"May we not also believe," added Cortlandt, "that in the
transfiguration Christ's companions took the substance of their
material bodies--the oxygen, hydrogen, nitrogen, and carbon--from
the air and the moisture it contained; for, though spiritual
bodies, be their activity magnetic or any other, could of course
pass the absolute cold and void of space without being affected,
no mortal body could; and that in the same manner Elijah's body
dissolved into air without the usual intervention of
decomposition; for we know that, though matter can easily change
its form, it can never be destroyed."

All assented to this, and Ayrault continued:  "If apergy can
annul gravitation, I do not see why it should not do more, for to
annul it the repulsion of the earth that it produces must be as
great as its attraction, unless we suppose gravitation for the
time being to be suspended; but whether it is or not, does not
affect the result in this case, for, after the apergetic
repulsion is brought to the degree at which a body does not fall,
any increase in the current's strength will cause it to rise, and
in the case of electro-magnets we know that the attraction or
repulsion has practically no limit.  This will be of great
advantage to us," he continued, "for if a projectile could move
away from the earth with no more rapid acceleration than that
with which it approaches, it would take too long to reach the
nearest planet, but the maximum repulsion being at the start by
reason of its proximity to the earth--for apergy, being the
counterpart of gravitation, is subject to Newton's and Kepler's
laws--the acceleration of a body apergetically charged will be
greatest at first.  Two inclined planes may have the same fall,
but a ball will reach the bottom of one that is steepest near the
top in less time than on any other, because the maximum
acceleration is at the start.  We are all tired of being stuck to
this cosmical speck, with its monotonous ocean, leaden sky, and
single moon that is useless more than half the time, while its
size is so microscopic compared with the universe that we can
traverse its great circle in four days.  Its possibilities are
exhausted; and just as Greece became too small for the
civilization of the Greeks, and as reproduction is growth beyond
the individual, so it seems to me that the future glory of the
human race lies in exploring at least the solar system, without
waiting to become shades."

"Should you propose to go to Mars or Venus?" asked Cortlandt.

"No," replied Ayrault, "we know all about Mars; it is but one
seventh the size of the earth, and as the axis is inclined more
than ours, it would be a less comfortable globe than this; while,
as our president here told us in his T. A. S. Company's report,
the axis of Venus is inclined to such a degree that it would be
almost uninhabitable for us.  It would be as if colonists tried
to settle Greenland, or had come to North America during its
Glacial period.  Neither Venus nor Mars would be a good place
now."

"Where should you propose to go?" asked Stillman.

"To Jupiter, and, if possible, after that to Saturn," replied
Ayrault; "the former's mean distance from the sun is 480,000,000
miles; but, as our president showed us, its axis is so nearly
straight that I think, with its internal warmth, there will be
nothing to fear from cold.  Though, on account of the planet's
vast size, objects on its surface weigh more than twice as much
as here, if I am able to reach it by means of apergy, the same
force will enable me to regulate my weight.  Will any one go with
me?"

"Splendid!" said Bearwarden.  "If Mr. Dumby, our vice-president,
will temporarily assume my office, nothing will give me greater
pleasure."

"So will I go, if there is room for me," said Cortlandt.  "I will
at once resign my place as Government expert, and consider it the
grandest event of my life."

"If I were not afraid of leaving Stillman here to his own
devices, I'd ask for a berth as well," said Deepwaters.

"I am afraid," said Stillman, "if you take any more, you will be
overcrowded."

"Modesty forbids his saying," said Deepwaters, "that it wouldn't
do for the country to have all its eggs in one basket."

"Are you not afraid you will find the surface hot, or even
molten?" asked Vice-President Dumby.  "With its eighty-six
thousand five hundred mile diameter, the amount of original
internal heat must have been terrific."

"No, said Cortlandt, "it cannot be molten, or even in the least
degree luminous, for, if it were, its satellites would be visible
when they enter its shadow, whereas they entirely disappear."

"I do not believe Jupiter's surface is even perceptibly warm,"
said Bearwarden.  "We know that Algol, known to the ancients as
the 'Demon Star,' and several other variable stars, are
accompanied by a dark companion, with which they revolve about a
common centre, and which periodically obscures part of their
light.  Now, some of these non-luminaries are nearly as large as
our sun, and, of course, many hundred times the size of Jupiter.
If these bodies have lost enough heat to be invisible, Jupiter's
surface at least must be nearly cold."

"In the phosphorescence of seawater," said Cortlandt, "and in
other instances in Nature, we find light without heat, and we may
soon be able to produce it in the arts by oxidizing coal without
the intervention of the steam engine; but we never find any
considerable heat without light."

"I am convinced," said Bearwarden, "that we shall find Jupiter
habitable for intelligent beings who have been developed on a
more advanced sphere than itself, though I do not believe it has
progressed far enough in its evolution to produce them.  I expect
to find it in its Palaeozoic or Mesozoic period, while over a
hundred years ago the English astronomer, Chambers, thought that
on Saturn there was good reason for suspecting the presence of
snow."

"What sort of spaceship do you propose to have?" asked the
vice-president.

"As you have to pass through but little air," said Deepwaters, "I
should suggest a short-stroke cylinder of large diameter, with a
flat base and dome roof, composed of aluminum, or, still better,
of glucinum or beryllium as it is sometimes called, which is
twice as good a conductor of electricity as aluminum, four times
as strong, and is the lightest of all known metals, having a
specific gravity of only two, which last property will be of
great use to you, for of course the more weight you have to
propel the more apergetic repulsion you will have to develop."

"I will get some drawing-paper I left outside in my trap," said
Ayrault, "when with your ideas we may arrive at something
definite," saying which, he left the room.

"He seems very cynical in his ideas of life and the world in
general," said Secretary Stillman, "for a man of his age, and one
that is engaged."

"You see," replied Bearwarden, "his fiancee is not yet a senior,
being in the class of two thousand and one at Vassar, and so
cannot marry him for a year.  Not till next June can this sweet
girl graduate come forth with her mortar-board and sheepskin to
enlighten the world and make him happy.  That is, I suspect, one
reason why he proposed this trip."



                          CHAPTER VII.

                          HARD AT WORK.


In a few moments Ayrault returned with pencils, a pair of
compasses, and paper.

"Let us see, in the first place," said Deepwaters, "how long the
journey will take.  Since a stone falls 16.09 feet the first
second, and 64+ feet the next, it is easy to calculate at what
rate your speed would increase with the repulsion twice that of
the ordinary traction.  But I think this would be too slow.  It
will be best to treble or quadruple the apergetic charge, which
can easily be done, in which case your speed will exceed the
muzzle-velocity of a projectile from a long-range gun, in a few
seconds.  As the earth's repulsion decreases, the attraction of
mars and Jupiter will increase, and, there being no resistance,
your gait will become more and more rapid till it is necessary to
reverse the charge to avoid being dashed to pieces or being
consumed like a falling star by the friction in passing through
Jupiter's atmosphere.  You can be on the safe side by checking
your speed in advance.  You must, of course, be careful to avoid
collisions with meteors and asteroids but if you do, they will be
of use to you, for by attracting or repelling them you can change
your course to suit yourself, and also theirs in inverse ratio to
their masses.  Jupiter's moons will be like head and stern lines
in enabling you to choose the part of the surface on which you
wish to land.  With apergy it is as essential to have some heavy
body on which to work, within range, as to have water about a
ship's propellers.  Whether, when apergy is developed,
gravitation is temporarily annulled, or reversed like the late
attraction of a magnet when the current is changed, or whether it
is merely overpowered, in which case your motion will be the
resultant of the two, is an unsettled and not very important
point; for, though we know but little more of the nature of
electricity than was known a hundred years ago, this does not
prevent our producing and using it."

"Jupiter, when in opposition," he continued, "is about
380,000,000 miles from us, and it takes light, which travels at
the rate of 190,000 miles a second, just thirty-four minutes to
reach the earth from Jupiter.  If we suppose the average speed of
your ship to be one- five-hundredth as great, it will take you
just eleven days, nineteen hours and twenty minutes to make the
journey.  You will have a fine view of Mars and the asteroids,
and when 1,169,000 miles from Jupiter, will cross the orbit of
Callisto, the fifth moon in distance from the giant planet.  That
will be your best point to steer by."

"I think," said Ayrault, "as that will be the first member of
Jupiter's system we pass, and as it will guide us into port, it
would be a good name for our ship, and you must christen her if
we have her launched."

"No, no," said Deepwaters, "Miss Preston must do that; but we
certainly should have a launch, for you might have to land in the
water, and you must be sure the ship is tight."

"Talking of tight ships," said Bearwarden, passing a decanter of
claret to Stillman, "may remind us that it is time to splice the
'main brace.'  There's a bottle of whisky and some water just
behind you," he added to Deepwaters, "while three minutes after I
ring this bell," he said, pressing a button and jerking a handle
marked '8,' "the champagne cocktails will be on the desk."

"I see you know his ways," said Stillman to Bearwarden, drooping
his eyes in Deepwaters's direction.

"Oh, yes, I've been here before," replied Deepwaters.  "You see,
we navy men have to hustle now-a-days, and can't pass our time in
a high-backed chair, talking platitudes."

At this moment there was a slight rumbling, and eight champagne
cocktails, with the froth still on, and straws on a separate
plate, shot in and landed on a corner of the desk.

"Help yourselves, gentlemen," said Bearwarden, placing them on a
table; "I hope we shall find them cold."

"Do you know," said Deepwaters to Ayrault, while rapidly making
his cocktail disappear, "the Callisto's cost with its outfit will
be very great, especially if you use glucinum, which, though the
ideal metal for the purpose, comes pretty high?  I suggest that
you apply to Congress for an appropriation.  This experiment
comes under the 'Promotion of Science Act,' and any bill for it
would certainly pass."

"No, indeed," replied Ayrault; "the Callisto trip will be a
privilege and glory I would not miss, and building her will be a
part of it.  I shall put in everything conducive to success, but
will come to the Government only for advice."

"I will send a letter to all our ambassadors and consuls," said
Stillman, "to telegraph the department anything they may know or
learn that will be of use in adjusting the batteries, controlling
the machine, or anything else, and will turn over to you in a
succinct form all information that may be relevant, for without
such sorting you would be overwhelmed."

"And I," said Deepwaters, "will order the commanders of our
vessels to give you a farewell salute at starting, and to pick
you up in case you fail.  When you have demonstrated the
suitability of apergy," he continued, "and the habitability of
Jupiter and Saturn--,which, with their five and eight moons,
respectively, and rings thrown in, must both be vastly superior
to our little second-rate globe--we will see what can be done
towards changing our orbit, and if we cannot swing a little
nearer to our new world or worlds.  Then we'll lower, or rather
raise, the boats in the shape of numerous Callistos, and have a
landing-party ready at each opposition, while a man or two can be
placed in charge of each projectile to bring it back in ballast.
Thus we may soon have regular interplanetary lines."

"As every place seems to have been settled from some other," said
Cortlandt, "I do not see why, with increased scientific
facilities, history should not repeat itself, and this be the
point from which to colonize the solar system; for, for the
present at least, it would seem that we could not get beyond
that."

"As it will be quite an undertaking to change the orbit, said
Deepwaters, "we shall have time meanwhile to absorb or run out
all inferior races, so that we shall not make the mistake of
extending the Tower of Babel."

"He is putting on his war-paint," said Stillman, "and will soon
want a planet to himself."

"I see no necessity for even changing the orbit," said
Bearwarden, "except for the benefit of those that remain.  If
this attempt succeeds, it can doubtless be repeated.  An increase
in eccentricity would merely shorten the journey, if aphelion
always coincided with opposition, which it would not."

"Let us know how you are getting on," said Deepwaters to Ayrault,
"and be sure you have the Callisto properly christened.  Step
lively there, landlubbers!" he called to Stillman; "I have an
appointment at Washington at one, and it is now twenty minutes
past twelve.  We can lunch on the way."

Ayrault immediately advertised for bids for the construction of a
glucinum cylinder twenty-five feet in diameter, fifteen feet high
at the sides, with a domed roof, bringing up the total height to
twenty-one feet, and with a small gutter about it to catch the
rain on Jupiter or any other planet they might visit.  The sides,
roof, and floor were to consist of two sheets, each one third of
an inch thick and six inches apart, the space between to be
filled with mineral wool, as a protection against the intense
cold of space.  There were also to be several keels and supports
underneath, on which the car should rest.  Large, toughened
plate-glass windows were to be let into the roof and sides, and
smaller ones in the floor, all to be furnished with thick shades
and curtains.  Ayrault also decided to have it divided into two
stories, with ceilings six and a half to seven and a half feet
high, respectively, with a sort of crow's nest or observatory at
the top; the floors to be lattice- work, like those in the
engine-room of a steamer, so that when the carpets were rolled up
they should not greatly obstruct the view.  The wide, flat base
and the low centre of gravity would, he saw, be of use in
withstanding the high winds that he knew often prevailed on
Jupiter.

As soon as possible he awarded the contract, and then entering
his smart electric trap, steered for Vassar University along what
was the old post-road--though its builders would not have
recognized it with its asphalt surface, straightened curves, and
easy grades--to ask his idol to christen the Callisto when it
should be finished.

Starting from the upper end of Central Park, he stopped to buy
her a bunch of violets, and then ran to Poughkeepsie in two
hours.

Sylvia Preston was a lovely girl, with blue eyes, brown hair, and
perfect figure, clear white skin, and just twenty.  She was
delighted to see him, and said she would love to christen the
Callisto or do anything else that he wished.  "But I am so sorry
you are going away," she went on.  "I hate to lose you for so
long, and we shall not even be able to write."

"Why couldn't we be married now," he asked, "and go to Jupiter
for our honeymoon?"

"I'm afraid, dear," she answered, "you would be sorry a few years
hence if I didn't take my degree; and, besides, as you have asked
those other men, there wouldn't be room for me."

"We could have made other arrangements," he replied, "had I been
able to persuade you to go."

"Won't you dine with us at Delmonico's this evening, and go to
the play?" she asked.  "Papa has taken a box."

"Of course I will," he said, brightening up.  "What are you going
to wear?"

"Oh, I suppose something light and cool, for it's so hot," she
answered.

"I'll go now, so as to be ready," he said, getting up and going
towards the door to which Sylvia followed him.

A man in livery stood at the step of the phaeton.  Ayrault got in
and turned on the current, and his man climbed up behind.

On turning into the main road Ayrault was about to increase his
speed, when Sylvia, who had taken a short cut appeared at the
wayside carrying her hat in one hand and her gloves in the other.

"I couldn't let you go all by yourself," she said.  "The fact is,
I wanted to be with you."

"You are the sweetest thing that ever lived, and I'll love you
all my days," he said, getting down and helping Sylvia to the
seat beside him.  "What a nuisance this fellow behind is!" he
continued--referring to the groom-- "for, though he is a Russian,
and speaks but little English, it is unpleasant to feel he is
there."

"You'll have to write your sweet nothings, instead of saying
them," Sylvia replied.

"For you to leave around for other girls to see," answered
Ayrault with a smile.

"I don't know what your other girls do," she returned, "but with
me you are safe."

Ayrault fairly made his phaeton spin, going up the grades like a
shot and down like a bird.  On reaching New York, he left Sylvia
at her house, then ran his machine to a florist's, where he
ordered some lilies and roses, and then steered his way to his
club, where he dressed for dinner.  Shortly before the time he
repaired to Delmonico's--which name had become historical, though
the founders themselves were long dead--and sat guard at a table
till Sylvia, wearing his flowers and looking more beautiful than
any of them, arrived with her mother and father, and Bearwarden,
whom they knew very well.

"How are the exams getting on, Miss Preston?" Bearwarden asked.

"Pretty well," she replied, with a smile.  "We had English
literature yesterday, and natural history the day before.  Next
week we have chemistry and philosophy."

"What are you taking in natural history?" asked Bearwarden, with
interest.

"Oh, principally physical geography, geology, and meteorology,"
she replied.  "I think them entrancing."

"It must be a consolation," said Ayrault, "when your best hat is
spoiled by rain, to know the reason why.  Your average," he
continued, addressing Sylvia, "was ninety in the semi-annuals,
and I haven't a doubt that the finals will maintain your record
for the year."

"Don't be too sure," she replied.  "I have been loafing awfully,
and had to engage a 'grind' as a coach."

After dinner they went to the play, where they saw a presentation
of Society at the Close of the Twentieth Century, which Sylvia
and Ayrault enjoyed immensely.

A few days after the Delmonico dinner, while Bearwarden,
Cortlandt, and Ayrault sat together discussing their plans, the
servant announced Ayrault's family physician, Dr. Tubercle
Germiny, who had been requested to call.

"Delighted to see you, doctor," said Ayrault, shaking hands.
"You know Col. Bearwarden, our President, and Dr. Cortlandt--an
LL. D., however, and not a medico."

"I have had the pleasure," replied Dr. Germiny, shaking hands
with both.

"As you may be aware, doctor," said Ayrault, when they were
seated, "we are about to take a short trip to Jupiter, and, if
time allows, to Saturn.  We have come to you, as one familiar
with every known germ, for a few precautionary suggestions and
advice concerning our medicine-chest."

"Indeed!" replied Dr. Germiny, "a thorough knowledge of
bacteriology is the groundwork of therapeutics.  It is
practically admitted that every ailment, with the exception of
mechanical injuries, is the direct result of a specific germ; and
even in accidents and simple fractures, no matter what may be the
nature of the bruise, a micro-organism soon announces its
presence, so that if not the parent, it is the inseparable
companion, in fact the shadow, of disease.  Now, though not the
first cause in this instance, it has been indubitably proved,
that much of the effect, the fever and pain, are produced and
continued by the active, omnipresent, sleepless sperm.  Either
kill the micrococcus or heal the wound, and you are free from
both.  It being, therefore, granted that the ills of life are in
the air, we have but to find the peculiar nature of the case in
hand, its habits, tastes, and constitution, in order to destroy
it.  Impoverish the soil on which it thrives, before its arrival,
if you can foresee the nature of the inoculation to which you
will be exposed, by a dilute solution of itself, and supply it
only with what it particularly dislikes.  For an already
established tubercle requiring rapid action of the blood, such as
may well exist among the birds and vertebrates of Jupiter and
Saturn, I suggest a hypodermic rattlesnake injection, while
hydrocyanic acid and tarantula saliva may also come in well.  The
combinations that so long destroyed us have already become our
panacea."

"I see you have these poisons at your fingers' ends," said
Ayrault, "and we shall feel the utmost confidence in the remedies
and directions you prescribe."

They found that, in addition to their medicine-chest, they would
have to make room for the following articles, and also many more:
six shot-guns (three double-barrel 12-bores, three magazine
10-bores,) three rifles, three revolvers; a large supply of
ammunition (explosive and solid balls), hunting-knives,
fishing-tackle, compass, sextant, geometrical instruments, canned
food for forty days, appliance for renewing air, clothing, rubber
boots, apergetic apparatus, protection-wires, aneroid barometer,
and kodaks.


                          CHAPTER VIII.

                            GOOD-BYE.

At last the preparations were completed, and it was arranged that
the Callisto should begin its journey at eleven o'clock A. M.,
December 21st--the northern hemisphere's shortest day.

Though six months' operations could hardly be expected to have
produced much change in the inclination of the earth's axis, the
autumn held on wonderfully, and December was pronounced very
mild.  Fully a million people were in and about Van Cortlandt
Park hours before the time announced for the start, and those
near looked inquiringly at the trim little air-ship, that, having
done well on the trial trip, rested on her longitudinal and
transverse keels, with a battery of chemicals alongside, to make
sure of a full power supply.

The President and his Cabinet--including, of course, the shining
lights of the State and Navy Departments--came from Washington.
These, together with Mr. and Mrs. Preston, and a number of people
with passes, occupied seats arranged at the sides of the
platform; while sightseers and scientists assembled from every
part of the world.

"There's a ship for you!" said Secretary Stillman to the
Secretary of the Navy.  "She'll not have to be dry-docked for
barnacles, neither will the least breeze make the passengers
sick."

"That's all you landlubbers think of," replied Deepwaters.  "I
remember one of the kings over in Europe said to me, as he
introduced me to the queen:  'Your Secretary of State is a great
man, but why does he always part his hair in the middle?'

"'So that it shall not turn his head,' I replied.

"'But with so gallant and handsome an officer as you to lean
upon,' he answered, 'I should think he could look down on all the
world.'  Whereupon I asked him what he'd take to drink."

"Your apology is accepted," replied Secretary Stillman.

Cortlandt also came from Washington, where, as chief of the
Government's Expert Examiners Board, he had temporary quarters.
Bearwarden sailed over the spectators' heads in one of the
Terrestrial Axis Straightening Company's flying machines, while
Ayrault, to avoid the crowd, had come to the Callisto early, and
was showing the interior arrangements to Sylvia, who had
accompanied him.  She was somewhat piqued because at the last
moment he had not absolutely insisted on carrying her off, or
offered, if necessary, to displace his presidential and
Doctor-of-Laws friends in order to make room.

"You will have an ideal trip," she said, looking over some
astronomical star-charts and photographic maps of Jupiter and
Saturn that lay on the table, with a pair of compasses, "and I
hope you won't lose your way."

"I shall need no compass to find my way back," replied Ayrault,
"if I ever succeed in leaving this planet; neither will
star-charts be necessary, for you will be a magnet stronger than
any compass, and, compared with my star, all others are dim."

"You should write a book," said Sylvia, "and put some of those
things in it."  She was wearing a bunch of forget-me-nots and
violets that she had cut from a small flower-garden of potted
plants Ayrault had sent her, which she had placed in her father's
conservatory.

At this moment the small chime clock set in the Callisto's
wood-work rang out quarter to eleven.  As the sounds died away,
Sylvia became very pale, and began to regret in her womanly way
that she had allowed her hero to attempt this experiment.

"Oh," she said, clinging to his arm, "it was very wrong of me to
let you begin this.  I was so dazzled by the splendour of your
scheme when I heard it, and so anxious that you should have the
glory of being the first to surpass Columbus, that I did not
realize the full meaning.  I thought, also, you seemed rather
ready to leave me," she added gently, "and so said little; you do
not know how it almost breaks my heart now that I am about to
lose you.  It was quixotic to let you undertake this journey."

"An undertaker would have given me his kind offices for one even
longer, had I remained here," replied Ayrault.  "I cannot live in
this humdrum world without you.  The most sustained excitement
cannot even palliate what seems to me like unrequited love."

"O Dick!" she exclaimed, giving him a reproachful glance, "you
mustn't say that.  You know you have often told me my reason for
staying and taking my degree was good.  My lot will be very much
harder than yours, for you will forget me in the excitement of
discovery and adventure; but I--what can I do in the midst of all
the old associations?"

"Never mind, sweetheart," he said, kissing her hand, "I have
seemed on the verge of despair all the time."

Seeing that their separation must shortly begin, Ayrault tried to
assume a cheerful look; but as Sylvia turned her eyes away they
were suspiciously moist.

Just one minute before the starting-time Ayrault took Sylvia back
to her mother, and, after pressing her hand and having one last
long look into her--or, as he considered them, HIS--deep-sea
eyes, he returned to the Callisto, and was standing at the foot
of the telescopic aluminum ladder when his friends arrived.  As
all baggage and impedimenta bad been sent aboard and properly
stowed the day before, the travellers had not to do but climb to
and enter by the second-story window.  It distressed Bearwarden
that the north pole's exact declination on the 21st day of
December, when the axis was most inclined, could not be figured
out by the hour at which they were to start, so as to show what
change, if any, had already been brought about, but the
astronomers were working industriously, and promised that, if it
were finished by midnight, they would telegraph the result into
space by flash-light code.

Raising his hat to his fiancee and his prospective
parents-in-law, Ayrault followed them up.  To draw in and fold
the ladder was but the work of a moment.  As the clocks in the
neighbouring steeples began to strike eleven, Ayrault touched the
switch that would correspond to the throttle of an engine, and
the motors began to work at rapidly increasing speed.  Slowly the
Callisto left her resting-place as a Galatea might her pedestal,
only, instead of coming down, she rose still higher.

A large American flag hanging from the window, which, as they
started, fluttered as in a southern zephyr, soon began to flap as
in a stiff breeze as the car's speed increased.  With a final
wave, at which a battery of twenty-one field-pieces made the air
ring with a salute, and the multitude raised a mighty cheer, they
drew it in and closed the window, sealing it hermetically in
order to keep in the air that, had an opening remained, would
soon have become rarefied.

Sylvia had waved her handkerchief with the utmost enthusiasm, in
spite of the sadness at her heart.  But she now had other use for
it in trying to hide her tears.  The Callisto was still going
straight up, with a speed already as great as a cannon ball's,
and was almost out of sight.  The multitude then began to
disperse, and Sylvia returned to her home.

Let us now follow the Callisto.  The earth and Jupiter not being
exactly in opposition, as they would be if the sun, the earth,
and Jupiter were in line, with the earth between the two, but
rather as shown in the diagram, the Callisto's journey was
considerably more than 380,000,000 miles, the mean opposition
distance.  As they wished to start by daylight--i. e., from the
side of the earth turned towards the sun--they could not steer
immediately for Jupiter, but were obliged to go a few hundred
miles in the direction of the sun, then change their course to
something like a tangent to the earth, and get their final right
direction in swinging near the moon, since they must be
comparatively near some material object to bring apergy into
play.

The maximum power being turned on, the projectile shot from the
earth with tremendous and rapidly increasing speed, by the
shortest course--i. e., a straight line--so that for the present
it was not necessary to steer.  Until beyond the limits of the
atmosphere they kept the greatest apergetic repulsion focused on
the upper part of their cylinder, so that its point went first,
and they encountered least possible  resistance.  Looking through
the floor windows, therefore, the travellers had a most superb
view.  The air being clear, the eastern border of North America
and the Atlantic were outlined as on a map, the blue of the ocean
and brownish colour of the land, with white snow- patches on the
elevations, being very marked.  The Hudson and the Sound appeared
as clearly  defined blue ribbons, and between and around the two
they could see New York.  They also saw the ocean dotted for
miles with points in which they recognized the marine spiders and
cruisers of the North Atlantic squadron, and the ships on the
home station, which they knew were watching them through their
glasses.

"I see," said Cortlandt, "that Deepwaters has been as good as his
word, and has his ships on the watch to rescue us in case we
fail."

"Yes," replied Bearwarden, "he is the right sort.  When he gave
that promise I knew his men would be there."

They soon perceived that they had reached the void of space, for,
though the sun blazed with a splendour they had never before
seen, the firmament was intensely black, and the stars shone as
at midnight.  Here they began to change their course to a curve
beginning with a spiral, by charging the Callisto apergetically,
and directing the current towards the moon, to act as an aid to
the lunar attraction, while still allowing the earth to repel,
and their motion gradually became the resultant of the two
forces, the change from a straight line being so gradual,
however, that for some minutes they scarcely perceived it.  The
coronal streamers about the sun, such as are visible on earth
during a total eclipse, shone with a halo against the
ultra-Cimmerian background, bursting forth to a height of twenty
or thirty thousand miles above the surface in vast cyclonic
storms, producing so rapid a motion that a column of incandescent
gas may move ten thousand miles in less than ten minutes.
Whether these great streaks were in part electrical phenomena
similar to the aurora borealis, or entirely of intensely heated
material thrown up by explosions within the sun's mass, they
could not tell even from their point of vantage.

"I believe," said Cortlandt, pointing to the streamers, "that
they are masses of gas thrown beyond the sun's atmosphere, which
expand enormously when the pressure to which they are subjected
in the sun is removed--for only in space freed from resistance
could they move at such velocities, and that their brilliancy is
increased by great electrical disturbance.  If they were entirely
the play of electrical forces, their change of place would be
practically instantaneous, which, however rapid their movement,
is not the case."


                            BOOK II.


                           CHAPTER I.

                     THE LAST OF THE EARTH.

Finding that they were rapidly swinging towards their proper
course, and that the earth in its journey about the sun would
move out of their way, they divided their power between repelling
the body they had left and increasing the attraction of the moon,
and then set about getting their house in order.

Bearwarden, having the largest appetite, was elected cook, the
others sagely divining that labour so largely for himself would
be no trial.  Their small but business- like-looking electric
range was therefore soon in full blast, with Bearwarden in
command.  It had enough current to provide heat for cooking for
four hundred hours, which was an ample margin, and it had this
advantage, that, no matter how much it was used, it could not
exhaust the air as any other form of heat would.

There were also a number of sixteen-candle-power incandescent
lamps, so that when passing through the shadow of a planet, or at
night after their arrival on Jupiter, their car would be brightly
illuminated.  They had also a good search-light for examining the
dark side of a satellite, or exploring the spaces in Saturn's
rings.  Having lunched sumptuously on canned chicken  soup, beef
a la jardiniere, and pheasant that had been sent them by some of
their admirers that morning, they put the bones and the glass can
that had contained the soup into the double-doored partition or
vestibule, placing a large sheet of cardboard to act as a wad
between the scraps and the outside door.  By pressing a button
they unfastened the outside door, and the articles to be disposed
of were shot off by the expansion of the air between the
cardboard disk and the inside door; after which the outside door
was drawn back to its place by a current sent through a magnet,
but little power being required to reclose it with no resisting
atmospheric pressure.  As the electricity ran along a wire
passing through a hermetically sealed opening in the floor, there
was no way by which more air than that in the vestibule could
escape; and as the somewhat flat space between the doors
contained less than one cubic foot, the air- pressure inside the
Callisto could not be materially lessened by a few openings.

"By filling the vestibule as full as possible," said Bearwarden,
"and so displacing most of its air, we shall be able to open the
outside door oftener without danger of rarefaction."

The things they had discharged flew off with considerable speed
and were soon out of sight; but it was not necessary for them to
move fast, provided they moved at all, for, the resistance being
nil, they would be sure to go beyond the range of vision,
provided enough time was allowed, even if the Callisto's speed
was not being increased by apergy, in which case articles outside
and not affected would be quickly left behind.

The earth, which at first had filled nearly half their sky, was
rapidly growing smaller.  Being almost between themselves and the
sun, it looked like a crescent moon; and when it was only about
twenty times the size of the moon they calculated they must have
come nearly two hundred thousand miles.  The moon was now on what
a sailor would call the starboard bow--i. e., to the right and
ahead.  Being a little more than three quarters full, and only
about fifty thousand miles off, it presented a splendid sight,
brilliant as polished silver, and about twenty-five times as
large as they had ever before seen it with the unaided eye.

It was just ten hours since they had started, and at that moment
9 A. M. in New York; but, though it was night there, the Callisto
was bathed in a flood of sunlight such as never shines on earth.
The only night they would have was on the side of the Callisto
turned away from the sun, unless they passed through some shadow,
which they intended to avoid on account of the danger of
colliding with a meteor in the dark.  The moon and the Callisto
were moving on converging lines, the curve on which they had
entered having swung them to the side nearest the earth; but they
saw that their own tremendous and increasing speed would carry
them in front of the moon in its nearly circular orbit.  Wishing
to change the direction of their flight by the moon's attraction,
they shut off the power driving them from the earth, whereupon
the Callisto turned its heavy base towards the moon.  They were
already moving at such speed that their momentum alone would
carry them hundreds of thousands of miles into space, and were
then almost abreast of the earth's satellite, which was but a few
thousand miles away.  The spectacle was magnificent.  As they
looked at it through their field glasses or with the unaided eye,
the great cracks and craters showed with the utmost clearness,
sweeping past them almost as the landscape flies past a railway
train.  There was something awe-inspiring in the vast antiquity
of that furrowed lunar surface, by far the oldest thing that
mortal eye can see, since, while observing the ceaseless
political or geological changes on earth, the face of this dead
satellite, on account of the absence of air and water and
consequent erosion, has remained unchanged for bygone ages, as it
doubtless will for many more.

They closely watched the Callisto's course.  At first it did not
seem to deflect from a straight line, and they stood ready to
turn on the apergetic force again, when the car very slowly began
to show the effect of the moon's near pull; but not till they had
so far passed it that the dark side was towards them were they
heading straight for Jupiter.  Then they again turned on full
power and got a send-off shove on the moon and earth combined,
which increased their speed so rapidly that they felt they could
soon shut off the current altogether and save their supply.

"We must be ready to watch the signals from the arctic circle,"
said Bearwarden.  "At midnight, if the calculations are finished,
the result will be flashed by the searchlight."  It was then ten
minutes to twelve, and the earth was already over four hundred
thousand miles away.  Focusing their glasses upon the region near
the north pole, which, being turned from the sun, was towards
them and in darkness, they waited.

"In this blaze of sunlight," said Cortlandt, "I am afraid we can
see nothing."

Fortunately, at this moment the Callisto entered the moon's
tapering shadow.

"This," said Ayrault, "is good luck.  We could of course have
gone into the shadow; but to change our course would have delayed
us, and we might have lost part of the chance of increasing our
speed."

"There will be no danger from, meteors or sub-satellites here,"
said Bearwarden, "for anything revolving about the moon at this
distance would be caught by the earth."

The sun had apparently set behind the moon, and they were
eclipsed.  The stars shone with the utmost splendour against the
dead-black sky, and the earth appeared as a large crescent, still
considerably larger than the satellite to which they were
accustomed.  Exactly at midnight a faint phosphorescent light,
like that of a glow-worm, appeared in the region of Greenland on
the planet they had left.  It gradually increased its strength
till it shone like a long white beam projected from a lighthouse,
and in this they beheld the work of the greatest search-light
ever made by man, receiving for a few moments all the electricity
generated by the available dynamos at Niagara and the Bay of
Fundy, the steam engines, and other sources of power in the
northern hemisphere.  The beam lasted with growing intensity for
one minute; it then spelled out with clean-cut intervals,
according to the Cable Code:  "23@ no' 6".  The southern
hemisphere pumps are now raising and storing water at full blast.
We have already begun to lower the Arctic Ocean."

"Victory!" shouted Bearwarden, in an ecstasy of delight.  "Nearly
half a degree in six months, with but one pole working.  If we
can add at this rate each time to the speed of straightening
already acquired, we can reverse our engines in five years, and
in five more the earth will be at rest and right."

"Look!" said Ayrault, "they are sending something else."  The
flashes came in rapid succession, reaching far into space.  With
their glasses fixed upon them, they made out these sentences:
"Our telescopes, in whatever part of the earth was turned towards
you, have followed you since you started, and did not lose sight
of you till you entered the moon's shadow.  On your present
course you will be in darkness till 12.16, when we shall see you
again."

On receiving this last earthly message, the travellers sprang to
their searchlight, and, using its full power, telegraphed back
the following:  "Many thanks to you for good news about earth,
and to Secretary Deepwaters for lending us the navy.  Result of
work most glorious.  Remember us to everybody.  Shadow's edge
approaching."

This was read by the men in the great observatories, who
evidently telephoned to the arctic Signal Light immediately, for
it flashed back:  "Got your message perfectly.  Wish you greatest
luck.  The T. A. S. Co. has decked the Callisto's pedestal with
flowers, and has ordered a tablet set up on the site to
commemorate your celestial journey."

At that moment the shadow swept by, and they were in the full
blaze of cloudless day.  The change was so great that for a
moment they were obliged to close their eyes.  The polished sides
of the Callisto shone so brightly that they knew they were easily
seen.  The power temporarily diverted in sending them the message
then returned to the work of draining the Arctic Ocean, which, as
the north pole was now returning to the sun, was the thing to do,
and the travellers resumed their study of the heavenly bodies.



                           CHAPTER II.

                         SPACE AND MARS.

Never before had the travellers observed the stars and planets
under such favourable conditions.  No air or clouds intervened,
and as the Callisto did not revolve on its axis there was no
necessity for changing the direction of the glasses.  After an
hour of this interesting work, however, as it was already late at
the longitude they had left on earth, and as they knew they had
many days in space before them, they prepared to go to bed.  When
ready, they had only to pull down the shades; for, as apergy was
not applied to them, but only to the Callisto, they still looked
upon the floor as down, and closed the heavy curtains to have
night or darkness.  They found that the side of the Callisto
turned constantly towards the sun was becoming very warm, the
double-toughened glass windows making it like a greenhouse; but
they consoled themselves with the thought that the sun's power on
them was hourly becoming less, and they felt sure the double
walls and thick upholstery would protect them almost anywhere
within the solar system from the intense cold of space.

"We could easily have arranged," said Ayrault, for night and day
on alternate sides of the Callisto by having strips of metal
arranged spirally on the outside as on the end of an arrow.
These would have started us turning as slowly as we like, since
we passed through the atmosphere at a comparatively low rate of
speed."

"I am afraid," said Cortlandt, "the motion, however slow, would
have made us dizzy.  It would be confusing to see the heavens
turning about us, and it would interfere with using the glasses."

The base and one side of the Callisto had constant sunshine,
while the other side and the dome were in the blackest night.
This dome, on account of its shape, sky windows, and the
completeness with which it could be isolated, was an ideal
observatory, and there was seldom a time during their waking
hours for the rest of the journey when it was not occupied by
one, two, or all the observers.

"There is something marvellous," said Cortlandt, "about the
condition of space.  Its absolute cold is appalling, apparently
because there is nothing to absorb heat; yet we find the base of
this material projectile uncomfortably warm, though, should we
expose a thermometer in the shade in front, we know it would show
a temperature of three hundred to four hundred degrees below
zero--were the instrument capable of recording it."

Artificial darkness having been obtained, the travellers were
soon asleep, Bearwarden's dreams being regaled with thoughts of
his company's triumph; Ayrault's, naturally, with visions of
Sylvia; while Cortlandt frequently started up, thinking he had
already made some great astronomical discovery.

About 9 A. M., according to seventy-fifth meridian time, the
explorers awoke feeling greatly refreshed.  The tank in which the
liquefied oxygen was kept automatically gave off its gas so
evenly that the air remained normal, while the lime contained in
cups absorbed the carbon dioxide as fast as they exhaled it.
They had darkened those windows through which the sun was
actually pouring, for, on account of the emptiness of the
surrounding ether and consequent absence of diffusion of light,
nothing but the inky blackness of space and the bright stars
looked in at the rest.  On raising the shades they got an idea of
their speed.  A small crescent, smaller than the familiar moon,
accompanied by one still tinier, was all that could be seen of
the earth and its satellite.

"We must," said Bearwarden, "be moving at the rate of nearly a
million miles an hour, from the way we have travelled."

"We must be doing fully a million," replied Cortlandt, "for by
this time we are pretty well in motion, having got a tremendous
start when so near the moon, with it and the earth in line."

By steering straight for Jupiter, instead of for the place it
would occupy ten days later, they knew they would swing past, for
the giant planet, being in rapid motion, would advance; but they
did not object to this, since it would give them a chance to
examine their new world in case they wished to do so before
alighting; while, if they preferred to land at once, they could
easily change their course by means of the moons, the fourth,
from which their car was named, being the one that they knew
would be of most use.  Their tremendous speed showed them they
should have time for exploration on their arrival, and that they
would reach their destination sooner than they had expected.  The
apergetic force being applied, as we have seen, only to the
Callisto, just as power in starting is exerted on a carriage or
railway car and only through it to the passengers, Ayrault and
his companions had no unusual sensation except loss of weight,
for, when they were so far from the earth, its attraction was
very slight, and no other planet was near enough to take its
place.  After breakfast, wishing to reach the dome, and realizing
that it would be unnecessary to climb, each in turn gave a slight
spring and was obliged to put up his hands to avoid striking the
roof.  In the cool quiet of the dark dome it was difficult to
believe that only twenty feet away the sun was shining with such
intensity upon the metal base as to make it too hot on the inside
to touch without gloves.

The first thing that attracted their attention was the size and
brilliance of Mars.  Although this red planet was over forty
million miles from the earth when they started, they calculated
that it was less than thirty million miles from them now, or five
millions nearer than it had ever been to them before.  This
reduction in distance, and the clearness of the void through
which they saw it, made it a splendid sight, its disk showing
clearly.  From hour to hour its size and brightness increased,
till towards evening it looked like a small, full moon, the sun
shining squarely upon it.  They calculated that on the course
they were moving they should pass about nine hundred thousand
miles to the right or behind it, since it was moving towards
their left.  They were interested to see what effect the mass of
Mars would have on the Callisto, and saw here a chance of still
further increasing their speed.  Notwithstanding its tremendous
rate, they expected to see the Callisto swerve from its straight
line and move towards Mars, whose orbital speed of nine hundred
miles a minute they thought would take it out of the Callisto's
way, so that no actual collision would occur even if their
air-ship were left to her own devices.

Towards evening they noticed through their glasses that several
apparently island peaks in the southern hemisphere, which was
turned towards them, became white, from which they concluded that
a snow-storm was in progress.  The south polar region was also
markedly glaciated, though the icecap was not as extensive as
either of those at the poles of the earth.

"As the Martian winters must be fully as severe as ours," said
Cortlandt, "on account of their length, the planet's distance
from the sun, and the twenty-seven and a half degrees inclination
of its axis, we can account for the smallness of its ice-caps
only by the fact that its oceans cover but one fourth of its
surface instead of three quarters, as on the earth, and there is
consequently a smaller evaporation and rain and snow-fall."

They were too much interested to think of sleeping that night,
and so, after dining comfortably returned to their observatory.
When within four million miles of Mars the Callisto began to
swerve perceptibly, its curve, as when near the moon beginning
with a spiral.  They swung on unconcernedly, however, knowing
they could check their approach at any time.  Soon Mars appeared
to have a diameter ten times as great as that of the moon, and
promised shortly to occupy almost one side of their sky.

"We must be on the lookout for the satellites," said Cortlandt;
"a collision with either would be worse than a wreck on a desert
island."

They therefore turned their glasses in the direction of the
satellites.

"Until Prof. Hall, at Washington, discovered the two satellites
in 1877," he continued, "Mars was supposed to be without moons.
The outer one, Deimos, is but six miles in diameter, and revolves
about its primary in thirty hours and eighteen minutes, at a
distance of fourteen thousand six hundred miles.  As it takes but
little longer to complete a revolution than Mars does to rotate
on its axis, it remains in the Martial sky one hundred and
thirty-two hours between rising and setting, passing through all
the phases from new moon to full and back again four times; that
is, it swings four times around Mars before going below the
horizon.  It is one of the smallest bodies discovered with a
telescope.  The inner one, Phobos, is considerably larger, having
a diameter of about twenty miles.  It is but twenty-seven hundred
miles from Mars's surface, and completes its revolution in seven
hours and thirty-eight minutes, which is shorter than any other
known period, Jupiter's nearest moon being the next, with eleven
hours and fifty- nine minutes.  It thus revolves in less than a
third of the time Mars takes to rotate, and must consequently
rise in the west and set in the east, as it is continually
running ahead of the surface of the planet, though the sun and
all the other stars rise and set on Mars in the same way as on
the earth."

When about fifteen thousand miles from Mars, they sighted Deimos
directly ahead, and saw that they should pass on its left--i. e.,
behind--for it was moving across them.  The sun poured directly
upon it, making it appear full and showing all its features.
There were small unevennesses on the surface, apparently seventy
or a hundred feet high, which were the nearest approach to
mountains, and they ran in ridges or chains.  There were also
unmistakable signs of volcanic action, the craters being large
compared with the size of the planet, but shallow.  They saw no
signs of water, and the blackness of the shadows convinced them
there was no air.  They secured two instantaneous photographs of
the little satellite as the Callisto swept by, and resumed their
inspection of Mars.  They noticed red and brownish patches on the
peaks that had that morning turned white, from which they
concluded that the show had begun to melt under the warm spring
sun.  This strengthened the belief they had already formed, that
on account of its twenty-seven and a half degrees inclination the
changes in temperature on Mars must be great and sudden.  So
interested were they with this, that they did not at first see a
large and bright body moving rapidly on a course that converged
with theirs.

"We must be ready to repel boarders," said Bearwarden, observing
it for the first time and fixing his glass upon it.  "That must
be Phobos."

Not ten miles off they beheld Mars's inner moon, and though their
own speed caused them to overtake and rush by it like a
whirlwind, the satellite's rapid motion in its orbit, in a course
temporarily almost parallel with theirs, served to give them a
chance the better to examine it.  Here the mountain ranges were
considerably more conspicuous than on Deimos, and there were
boulders and loose stones upon their slopes, which looked as if
there might at some time have been frost and water on its
surface; but it was all dry now, neither was there any air.  The
evidences of volcanic action were also plainly visible, while a
noticeable flattening at the poles showed that the little body
had once rotated rapidly on its axis, though whether it did so
still they had not time to ascertain.  When abreast of it they
were less than two miles distant, and they secured several
instantaneous impressions, which they put aside to develop later.
As the radius of Phobos's circle was far shorter than that of the
parabolic curve they were making, it began to draw away, and was
rapidly left behind.  Applying the full apergetic force to Mars
and the larger moon, they shot away like an arrow, having had
their speed increased by the planet's attraction while
approaching it, and subsequently by repulsion.

"Either of those," said Bearwarden, looking back at the little
satellites, "would be a nice yacht for a man to explore space on.
He would also, of course, need a sun to warm him, if he wished to
go beyond this system, but that would not have to be a large
affair--in fact, it might be smaller than the planet, and could
revolve about it like a moon."

"Though a sun of that size," replied Cortlandt, "might retain its
heat for the time you wished to use it, the planet part would be
nothing like as comfortable as what we have here, for it would be
very difficult to get enough air-pressure to breathe on so small
a body, since, with its slight gravitation-pull, to secure
fifteen pounds to the square inch, or anything like it, the
atmosphere would have to extend thousands of miles into space, so
that on a cloudy day you would be in darkness.  It would be
better, therefore, to have such a sun as you describe and
accompany it in a yacht or private car like this, well stocked
with oxygen and provisions.  When passing through meteoric swarms
or masses of solid matter, collision with which is the most
serious risk we run, the car could follow behind its sun instead
of revolving around it, and be kept from falling into it by
partially reversing the attraction.  As the gravitation of so
small a sun would be slight, counteracting it for even a
considerable time would take but little from the batteries."

"There are known to be several unclaimed masses," added Ayrault,
"with diameters of a few hundred yards, revolving about the earth
inside the orbit of the moon.  If in some way two of these could
be brought into sufficiently violent collision, they would become
luminous and answer very well; the increase in bulk as a result
of the consolidation, and the subsequent heat, about serving to
bring them to the required size.  Whenever this sun showed spots
and indications of cooling, it could be made to collide with the
solid head of some comet, or small asteroid, till its temperature
was again right; while if, as a result of these accretions, it
became unwieldy, it could be caused to rotate with sufficient
rapidity on its axis to split, and we should have two suns
instead of one."

"Bravo!" said Bearwarden.  "There is no limit to what can be
done.  The idea of our present trip would have seemed more
chimerical to people a hundred years ago than this new scheme
appears now."

Thus they sat and talked, or studied maps and star- charts, or
the stars themselves, while the hours quickly passed and they
shot through space.  They had now a straight stretch of over
three hundred million miles, and had to cross the orbits of
innumerable asteroids on the way.  The apparent size of the sun
had by this time considerably decreased, and the interior of the
Callisto was no longer uncomfortably warm.  They divided the day
into twenty-four hours from force of habit, and drew the shades
tightly during what they considered night, while Bearwarden
distinguished himself as a cook.



                          CHAPTER III.

                        HEAVENLY BODIES.

The following day, while in their observatory, they saw something
not many miles ahead.  They watched it for hours, and in fact all
day, but notwithstanding their tremendous speed they came but
little nearer.

"They say a stern chase is a long one," said Bearwarden; but that
beats anything I have ever seen."

After a while, however, they found they WERE nearer, the time
taken having been in part due to the deceptive distance, which
was greater than they supposed.

"A comet!" exclaimed Cortlandt excitedly.  "We shall really be
able to examine it near."

"It's going in our direction," said Ayrault, "and at almost
exactly our speed."

While the sun shone full upon it they brought their camera into
play, and again succeeded in photographing a heavenly body at
close range.  The nucleus or head was of course turned towards
the sun; while the tail, which they could see faintly, preceded
it, as the comet was receding towards the cold and dark depths of
space.  The head was only a few miles in diameter, for it was a
small comet, and was composed of grains and masses of stone and
meteoric iron.  Many of the grains were no larger than peas or
mustard-seeds; no mass was more than four feet in diameter, and
all of them had very irregular shapes.  The space between the
particles was never less than one hundred times their masses.

"We can move about within it," said Ayrault, as the Callisto
entered the aggregation of particles, and moved slowly forward
among them.

The windows in the dome, being made of toughened glass, set
somewhat slantingly so as to deflect anything touching them, and
having, moreover, the pressure of the inside air to sustain them,
were fairly safe, while the windows in the sides and base were
but little exposed.  Whenever a large mass seemed dangerously
near the glass, they applied an apergetic shock to it and sent it
kiting among its fellows.  At these times the Callisto recoiled
slightly also, the resulting motion in either being in inverse
ratio to its weight.  There was constant and incessant movement
among the individual fragments, but it was not rotary.  Nothing
seemed to be revolving about anything else; all were moving,
apparently swinging back and forth, but no collisions took place.
When the separate particles got more than a certain distance
apart they reapproached one another, but when seemingly within
about one hundred diameters of each other they swung off in some
other direction.  The motion was like that of innumerable
harp-strings, which may approach but never strike one another.
After a time the Callisto seemed to become endowed with the same
property that the fragments possessed; for it and they repelled
one another, on a near approach, after which nothing came very
near.

Much of the material was like slag from a furnace, having
evidently been partly fused.  Whether this heat was the result of
collision or of its near approach to the sun at perihelion, they
could not tell, though the latter explanation seemed most simple
and probable.  When at about the centre of the nucleus they were
in semi-darkness--not twilight, for any ray that succeeded in
penetrating was dazzlingly brilliant, and the shadows, their own
included, were inky black.  As they approached the farther side
and the sunlight decreased, they found that a diffused luminosity
pervaded everything.  It was sufficiently bright to enable them
to see the dark side of the meteoric masses, and, on emerging
from the nucleus in total darkness, they found the shadow
stretching thousands of miles before them into space.

"I now understand," said Bearwarden, "why stars of the sixth and
seventh magnitude can be seen through thousands of miles of a
comet's tail.  It is simply because there is nothing in it.  The
reason ANY stars are obscured is because the light in the tail,
however faint, is brighter than they, and that light is all that
the caudal appendage consists of, though what produces it I
confess I am unable to explain.  I also see why the tail always
stretches away from the sun, because near by it is overwhelmed by
the more powerful light; in fact, I suspect it is principally in
the comet's shadow that the tail is visible.  It is strange that
no one ever thought of that before, or that any one feared the
earth's passing through the tail of a comet.  It is obvious to me
now that if there were any material substance, any gas, however
rarefied, in this hairlike[1] accompaniment, it would immediately
fall to the comparatively heavy head,
and surround that as a centre."

[1]  Comet means literally a hair.


"How, then," asked Cortlandt, "do you account for the spaces
between those stones?  However slight gravitation might be
between some of the grains, if it existed at all, or was
unopposed by some other force, with sufficient time--and they
have eternity--every comet would come together like a planet into
one solid mass.  Perhaps some similar force maintains gases in
the distended tail, though I know of no such, or even any
analogous manifestation on earth.  If the law on which we have
been brought up, that 'every atom in the universe attracts every
other atom,' were without exceptions or modifications, that comet
could not continue to exist in its present form.  Until we get
some additional illustration, however, we shall be short of data
with which to formulate any iconoclastic hypothesis.  The source
of the light, I must admit, also puzzles me greatly.  There is
certainly no heat to which we can attribute it."

Having gone beyond the fragments, they applied a strong repulsion
charge to the comet, creating thereby a perfect whirlpool among
its particles, and quickly left it.  Half an hour later they
again shut off the current, as the Callisto's speed was
sufficient.

For some time they had been in the belt of asteroids, but as yet
they had seen none near.  The morning following their experience
with the comet, however, they went to their observatory after
breakfast as usual, and, on pointing their glasses forward,
espied a comparatively large body before them, a little to their
right.

"That must be Pallas," said Cortlandt, scrutinizing it closely.
"It was discovered by Olbers, in 1802, and was the second
asteroid found, Ceres having been the first, in 1801.  It has a
diameter of about three hundred miles, being one of the largest
of these small planets.  The most wonderful thing about it is the
inclination of its orbit--thirty-five degrees--to the plane of
the ecliptic; which means that at each revolution in its orbit,
it swings that much above and below the imaginary plane cutting
the sun at its equator, from which the earth and other larger
planets vary but little.  This no doubt is due to the near
approach and disturbing attraction of some large comet, or else
it was flung above or below the ordinary plane in the catastrophe
that we think befell the large planet that doubtless formerly
existed where we now find this swarm.  You can see that its path
makes a considerable angle to the plane of the ecliptic, and that
it is now about crossing the line."

It soon presented the phase of a half moon, but the waviness of
the straight line, as in the case of Venus and Mercury, showed
that the size of the mountains must be tremendous compared with
the mass of the body, some of them being obviously fifteen miles
high.  The intense blackness of the shadows, as on the moon,
convinced them there was no trace of atmosphere.

"There being no air," said Cortlandt, "it is safe to assume there
is no water, which helps to account for the great inequalities on
the body's surface, since the mountains will seem higher when
surrounded by dry ocean- bottom than they would if water came
halfway up their sides.  Undoubtedly, however, the main cause of
their height is the slight effect of gravitation on an asteroid,
and the fact that the shrinking of the interior, and consequent
folding of the crust in ridges, may have continued for a time
after there was no longer water on the surface to cut them down.

"The temperature and condition of a body," continued Cortlandt,
"seem to depend entirely on its size.  In the sun we have an
incandescent, gaseous star, though its spots and the colour of
its rays show that it is becoming aged, or, to be more accurate,
advanced in its evolutionary development.  Then comes a great
jump, for Jupiter has but about one fourteen-hundredth of the
mass of the sun, and we expect to find on it a firm crust, and
that the planet itself is at about the fourth or fifth  period of
development, described by Moses as days.  Saturn is doubtless
somewhat more advanced.  The earth we know has been habitable
many hundreds of thousands or millions of years, though three
fourths of its surface is still covered by water.  In Mars we see
a further step, three fourths of its surface being land.  In
Mercury, could we study it better, or in the larger satellites of
Jupiter or Saturn, we might find a stepping-stone from Mars to
the moon, perhaps with no water, but still having air, and being
habitable in all other respects.  In our own satellite we see a
world that has died, though its death from an astronomical point
of view is comparatively recent, while this little Pallas has
been dead longer, being probably chilled through and through.
From this I conclude that all bodies in the solar system had one
genesis, and were part of the same nebulous mass.  But this does
not include the other systems and nebulae; for, compared with
them, our sun, as we have seen, is itself advanced and small
beside such stars as Sirius having diameters of twelve million
miles."

As they left Pallas between themselves and the sun, it became a
crescent and finally disappeared.

Two days later they sighted another asteroid exactly ahead.  They
examined it closely, and concluded it must be Hilda, put down in
the astronomies as No. 153, and having almost the greatest mean
distance of any of these small bodies from the sun.

When they were so near that the disk was plainly visible to the
unaided eye, Hilda passed between them and Jupiter, eclipsing it.
To their surprise, the light was not instantly shut off, as when
the moon occults a star, but there was evident refraction.

"By George!" said Bearwarden, "here is an asteroid that HAS an
atmosphere."

There was no mistaking it.  They soon discovered a small ice-cap
at one pole, and then made out oceans and continents, with
mountains, forests, rivers, and green fields.  The sight lasted
but a few moments before they swept by, but they secured several
photographs, and carried a vivid impression in their minds.
Hilda appeared to be about two hundred miles in diameter.

"How do you account for that living world," Bearwarden asked
Cortlandt, "on your theory of size and longevity?"

"There are two explanations," replied Cortlandt, "if the theory,
as I still believe, is correct.  Hilda has either been brought to
this system from some other less matured, in the train of a
comet, and been captured by the immense power of "Jupiter, which
might account for the eccentricity of its orbit, or some accident
has happened to rejuvenate it here.  A collision with another
minor planet moving in an orbit that crossed its own, or with the
head of a large comet, would have reconverted it into a star,
perhaps after it had long been cold.  A comet may first have so
changed the course of one of two small bodies as to make them
collide.  This seems to me the most plausible theory.  Over a
hundred years ago the English astronomer, Chambers, wrote of
having found traces of atmosphere in some of these minor planets,
but it was generally thought he was mistaken.  One reason we know
so little about this great swarm of minor planets is, that till
recently none of them showed a disk to the telescope.  Inasmuch
as only their light was visible, they were indistinguishable from
stars, except by their slow motion.  A hundred years ago only
three hundred and fifty had been discovered; our photographic
star-charts have since then shown the number recorded to exceed
one thousand."


                           CHAPTER IV.

                      PREPARING TO ALIGHT.

That afternoon Ayrault brought out some statistical tables he had
compiled from a great number of books, and also a diagram of the
comparative sizes of the planets.  "I have been not a little
puzzled at the discrepancies between even the best authors," he
said, "scarcely any two being exactly alike, while every decade
has seen accepted theories radically changed."  Saying which, he
spread out the result of his labours (shown on the following
pages), which the three friends then studied.

"You see," Ayrault explained, "on Jupiter we shall need our
apergetic outfits to enable us to make long marches, while on
Saturn they will not be necessary, the increase in our weight as
a result of that planet's size being considerably less than the
usual load carried by the Roman soldier."

"I do not imagine," said Cortlandt, "we should long be troubled
by gravitation without our apergetic outfits even on Jupiter,
for, though our weight will be more than doubled, we can take off
one quarter of the whole by remaining near the equator, their
rapid rotation having apparently been given providentially to all
the large planets.  Nature will adapt herself to this change, as
to all others, very readily.  Although the reclamation of the
vast areas of the North American Arctic Archipelago, Alaska,
Siberia, and Antarctic Wilkes Land, from the death-grip of the
ice in which they have been held will relieve the pressure of
population for another century, at the end of that time it will
surely be felt again; it is therefore a consolation to feel that
the mighty planets Jupiter and Saturn, which we are coming to
look upon as our heritage, will not crush the life out of any
human beings by their own weight that may alight upon them."

Before going to bed that evening they decided to be up early the
next day, to study Jupiter, which was already a brilliant object.

The following morning, on awakening, they went at once to their
observatory, and found that Jupiter's disk was plainly visible to
the naked eye, and before night it seemed as large as the full
moon.

They then prepared to check the Callisto's headlong speed, which
Jupiter's attraction was beginning to increase.  When about two
million miles from the great planet, which was considerably on
their left, they espied Callisto ahead and slightly on their
right, as Deepwaters had calculated it would be.  Applying a mild
repulsion to this--which was itself quite a world, with its
diameter of over three thousand miles, though evidently as cold
and dead as the earth's old moon--they retarded their forward
rush, knowing that the resulting motion towards Jupiter would be
helped by the giant's pull.  Wishing to be in good condition for
their landing, they divided the remainder of the night into
watches, two going to sleep at a time, the man on duty standing
by to control the course and to get photographic negatives, on
which, when they were developed, they found two crescent-shaped
continents, a speckled region, and a number of islands.  By 7 A.
M., according to Eastern standard time, they were but fifty
thousand miles from Jupiter's surface, the gigantic globe filling
nearly one side of the sky.  In preparation for a sally, they got
their guns and accoutrements ready, and then gave a parting
glance at the car.  Their charge of electricity for developing
the repulsion seemed scarcely touched, and they had still an
abundant supply of oxygen and provisions.  The barometer
registered twenty-nine inches, showing that they had not lost
much air in the numerous openings of the vestibule.  The pressure
was about what would be found at an altitude of a few hundred
feet, part of the rarefaction being no doubt due to the fact that
they did not close the windows until at a considerable height
above Van Cortlandt Park.

They saw they should alight in a longitude on which the sun had
just risen, the rocky tops of the great mountains shining like
helmets in its rays.  Soon they felt a sharp checking of their
forward motion, and saw, from the changed appearance of the stars
and the sun, that they had entered the atmosphere of their new
home.

Not even did Columbus, standing at the prow of the Santa Maria,
with the New World before him, feel the exultation and delight
experienced by these latter-day explorers of the twenty-first
century.  Their first adventures on landing the reader already
knows.



                           CHAPTER V.

                   EXPLORATION AND EXCITEMENT.

When they awoke, the flowers were singing with the volume of a
cathedral organ, the chant rising from all around them, and the
sun was already above the horizon.  Finding a deep natural
spring, in which the water was at about blood-heat, they prepared
for breakfast by taking a bath, and then found they had brought
nothing to eat.

"It was stupid of us not to think of it," said Bearwarden, "yet
it will be too much out of our way to return to the Callisto."

"We have two rifles and a gun," said Ayrault, "and have also
plenty of water, and wood for a fire.  All we need is game."

"The old excuse, that it has been already shot out, cannot hold
here," said Cortlandt.

"Seeing that we have neither wings nor pneumatic legs, and not
knowing the advantage given us by our rifles," added Bearwarden,
"it should not be shy either.  So far," he continued, "we have
seen nothing edible, though just now we should not be too
particular; but near a spring like this that kind must exist."

"The question is," said the professor, "whether the game like
warm water.  If we can follow this stream till it has been on the
surface for some time, or till it spreads out, we shall doubtless
find a huntsman's paradise."

"A bright idea," said Bearwarden.  "Let's have our guns ready,
and, as old Deepwaters would say, keep our weather eye open."

The stream flowed off in a southeasterly direction, so that by
following it they went towards the volcanoes.

"It is hard to realize," said the professor, "that those
mountains must be several hundred miles away, for the reason that
they are almost entirely above the horizon.  This apparent
flatness and wide range of vision is of course the result of
Jupiter's vast size.  With sufficiently keen sight, or aided by a
good glass, there is no reason why one should not see at least
five hundred miles, with but a slight elevation."

"It is surprising," said Ayrault, "that in what is evidently
Jupiter's Carboniferous period the atmosphere should be so clear.
Our idea has been that at that time on earth the air was heavy
and dense."

"So it was, and doubtless is here," replied Cortlandt; "but you
must remember that both those qualities would be given it by
carbonic-acid gas, which is entirely invisible and transparent.
No gas that would be likely to remain in the air would interfere
with sight; water vapour is the only thing that could; and though
the crust of this planet, even near the surface, is still hot,
the sun being so distant, the vapour would not be, raised much.
By avoiding low places near hot springs, we shall doubtless have
very nearly as clear an atmosphere as on earth.  What does
surprise me is the ease with which we breathe.  I can account for
it only by supposing that, the Carboniferous period being already
well advanced, most of the carbonic acid is already locked up in
the forests or in Jupiter's coal-beds."

"How, asked Bearwarden, "do you account for the 'great red spot'
that appeared here in 1878, lasted several years, and then
gradually faded?  It was taken as unmistakable evidence that
Jupiter's atmosphere was filled with impenetrable banks of cloud.
In fact, you remember many of the old books said we had probably
never seen the surface."

"That has puzzled me very much," replied Cortlandt, "but I never
believed the explanation then given was correct.  The
Carboniferous period is essentially one of  great forest growth;
so there would be nothing out of the way in supposing the spot,
notwithstanding its length of twenty-seven thousand miles and its
breadth of eight thousand miles, to have been forest.  It
occurred in what would correspond to the temperate region on
earth.  Now, though the axis of this planet is practically
straight, the winds of course change their direction, and so the
temperature does vary from day to day.  What is more probable
than that, owing perhaps to a prolonged norther or cold spell, a
long strip of forest lying near the frost line was brought a few
degrees below it, so that the leaves changed their colours as
they do on earth?  It would, it seems to me, be enough to give
the surface a distinct colour; and the fact that the spot's
greatest length was east and west, or along the lines of
latitude, so that the whole of that region might have been
exposed to the same conditions of temperature, strengthens this
hypothesis.  The strongest objection is, that the spot is said to
have moved; but the motion--five seconds--was so slight that it
might easily have been an error in observation, or the first area
affected by the cold may have been enlarged on one side.  It
seems to me that the stability the spot DID have would make the
cloud theory impossible on earth, and much more so here, with the
far more rapid rotation and more violent winds.  It may also have
been a cloud of smoke from a volcano in eruption, such as we saw
on our arrival, though it is doubtful whether in that case it
would have remained nearly stationary while going through its
greatest intensity and fading, which would look as though the
turned leaves had fallen off and been gradually replaced by new
ones; and, in addition to this, the spot since it was first
noticed has never entirely disappeared, which might mean a
volcanic region constantly emitting smoke, or that the surface,
doubtless from some covering whose colour can change, is normally
of a different shade from the surrounding region.  In any case,
we have as yet seen nothing that would indicate a permanently
clouded atmosphere."

Though they had walked a considerable distance, the water was not
much cooled; and though the stream's descent was so slight that
on earth its current would have been very slow, here it rushed
along like a mountain torrent, the reason, of course, being that
a given amount of water on Jupiter would depress a spring balance
2.55 times as much as on the earth.

"It is strange," said Ayrault, "that, notwithstanding its great
speed, the water remains so hot; you would think its motion would
cool it."

"So it does," answered the professor.  "It of course cools
considerably more in a given period--as, for instance, one
minute--than if it were moving more slowly, but on account of its
speed it has been exposed to the air but a very short time since
leaving the spring."

Just before them the stream now widened into a narrow lake, which
they could see was straight for some distance.

"The fact is," said Bearwarden, "this water seems in such haste
to reach the ocean that it turns neither to right nor to left,
and does not even seem to wish to widen out."

As the huge ferns and palms grew to the water's edge, they
concluded the best way to traverse the lake would be on a raft.
Accordingly, choosing a large overhanging palm, Bearwarden and
Ayrault fired each an explosive ball into its trunk, about
eighteen inches from the ground.  One round was enough to put it
in the water, each explosion removing several cubic feet of wood.
By repeating this process on other trees they soon had enough
large timber for buoyancy, so that they had but to superimpose
lighter cross-logs and bind the whole together with pliable
branches and creepers to form a substantial raft.  The doctor
climbed on, after which Bearwarden and Ayrault cast off, having
prepared long poles for navigating.  With a little care they kept
their bark from catching on projecting roots, and as the stream
continued to widen till it was about one hundred yards across,
their work became easy.  Carried along at a speed of two or three
miles an hour, they now saw that the water and the banks they
passed were literally alive with reptiles and all sorts of
amphibious creatures, while winged lizards sailed from every
overhanging branch into the water as they approached.  They
noticed also many birds similar to storks and cranes, about the
size of ostriches, standing on logs in the water, whose bills
were provided with teeth.

"We might almost think we were on earth," said Ayrault, "from the
looks of those storks standing on one leg, with the other drawn
up, were it not for their size."

"How do you suppose they defend themselves," asked Bearwarden,
"from the snakes with which the water is filled?"

"I suspect they can give a pretty good account of themselves,"
replied Cortlandt, "with those teeth.  Besides, with only one leg
exposed, there is but a very small object for a snake to strike
at.  For their number and size, I should say their struggle for
existence was comparatively mild.  Doubtless non-poisonous, or,
for that matter, poisonous snakes, form a great part of their
diet."

On passing the bend in the lake they noticed that the banks were
slightly higher, while palms, pine-trees, and rubber plants
succeeded the ferns.  In the distance they now heard a tremendous
crashing, which grew louder as the seconds passed.  It finally
sounded like an earthquake.  Involuntarily they held their breath
and grasped their weapons.  Finally, at some distance in the
woods they saw a dark mass moving rapidly and approaching the
river obliquely.  Palms and pine-trees went down before it like
straws, while its head was continually among the upper branches.
As the monster neared the lake, the water at the edges quivered,
showing how its weight shook the banks at each stride, while
stumps and tree-trunks on which it stepped were pressed out of
sight in the ground.  A general exodus of the other inhabitants
from his line of march began; the moccasins slid into the water
with a low splash, while the boa-constrictors and the tree-snakes
moved off along the ground when they felt it tremble, and a
number of night birds retreated into the denser woods with loud
cries at being so rudely disturbed.  The huge beast did not stop
till he reached the bank, where lie switched his tail, raised his
proboscis, and sniffed the air uneasily, his height being fully
thirty feet and his length about fifty.  On seeing the raft and
its occupants, he looked at them stupidly and threw back his
head.

"He seems to be turning up his nose at us," said Bearwarden.
"All the same, he will do well for breakfast."

As the creature moved, his chest struck a huge overhanging palm,
tearing it off as though it had been a reed.  Brushing it aside
with his trunk, he was about to continue his march, when two
rifle reports rang out together, rousing the echoes and a number
of birds that screeched loudly.



                           CHAPTER VI.

                 MASTODON AND WILL-O'-THE WISPS.

Bearwarden's bullet struck the mammoth in the shoulder, while
Ayrault's aim was farther back.  As the balls exploded, a
half-barrelful of flesh and hide was shot from each, leaving two
gaping holes.  Instantly he rushed among the trees, making his
course known for some time by his roars.  As he turned,
Bearwarden fired again, but the hall flew over him, blowing off
the top of a tree.

"Now for the chase!" said Ayrault.  "There would be no excuse for
losing him."

Quickly pushing their raft to shore and securing it to the bank,
the three jumped off.  Thanks to their rubber boots and galvanic
outfits which automatically kept them charged, they were as spry
as they would have been on earth.  The ground all about them, and
in a strip twelve feet wide where the mammoth had gone, was torn
up, and the vegetation trodden down.  Following this trail, they
struck back into the woods, where in places the gloom cast by the
thick foliage was so dense that there was a mere twilight,
startling as they went numbers of birds of grey and sombre
plumage, whose necks and heads, and the sounds they uttered, were
so reptilian that the three terrestrials believed they must also
possess poison fangs.

"The most highly developed things we have seen here," said
Bearwarden, "are the flowers and fireflies, most of the birds and
amphibians being simply loathsome."

As they proceeded they found tracks of blood, which were rapidly
attracting swarms of the reptile birds and snakes, which,
however, as a rule, fled at their approach.

"I wonder what can have caused that mammoth to move so fast, and
to have seemed so ill at ease?" said the doctor.  "His motive
certainly was not thirst, for he did not approach the water in a
direct line, neither did he drink on reaching it.  One would
think nothing short of an earthquake or a land-slide could
trouble him."

"There can be no land-slide here," said Ayrault, for the country
is too flat."

"And after yesterday's eruptions," added Bearwarden, "it would
seem as though the volcanoes could have scarcely enough steam
left to make trouble."

The blood-tracks, continuing to become fresher, showed them they
were nearing the game, when suddenly the trail took a sharp turn
to the right, even returning towards the lake.  A little farther
it took another sharp turn, then followed a series of doublings,
while still farther the ground was completely denuded of trees,
its torn-up and trampled condition and the enormous amount of
still warm blood showing how terrific a battle had just taken
place.

While they looked about they saw what appeared to be the trunk of
a tree about four feet in diameter and six feet long, with a
slight crook.  On coming closer, they recognized in it one of the
forefeet of the mammoth, cut as cleanly as though with a knife
from the leg just above the ankle, and still warm.  A little
farther they found the huge trunk cut to slivers, and, just
beyond, the body of the unfortunate beast with three of its feet
gone, and the thick hide cut and slashed like so much paper.  It
still breathed, and Ayrault, who had a tender heart, sent an
explosive ball into its skull, which ended its suffering.

The three hunters then surveyed the scene.  The largest and most
powerful beast they had believed could exist lay before them
dead, not from the bite of a snake or any other poison, but from
mechanical injuries of which those they had inflicted formed but
a very small part, and literally cut to pieces.

"I am curious to see the animal," said Cortlandt, "capable of
doing this, though nothing short of dynamite bombs would protect
us from him."

"As he has not stopped to eat his victim," said Bearwarden, "it
is fair to suppose he is not carnivorous, and so must have had
some other motive than hunger in making the attack; unless we can
suppose that our approach frightened him away, which, with such
power as he must possess, seems unlikely.  Let us see," he
continued, "parts of two legs remain unaccounted for.  Perhaps,
on account of their shape, he has been able the more easily to
carry or roll them off, for we know that elephant foot makes a
capital dish."

"From the way you talk," said Cortlandt, "one would suppose you
attributed this to men.  The Goliath we picture to ourselves
would be a child compared to the man that could cut through these
legs, though the necessity of believing him to have merely great
size does not disprove his existence here.  I think it probable
we shall find this is the work of some animal with incisors of
such power as it is difficult for us to conceive of."

"There is no indication here of teeth," said Bearwarden, "each
foot being taken off with a clean cut.  Besides, we are coming to
believe that man existed on earth during the greater part, if not
the whole, of our Carboniferous period."

"We must reserve our decision pending further evidence," said
Cortlandt.

"I vote we take the heart," said Ayrault, "and cook it, since
otherwise the mammoth will be devoured before our eyes."

While Bearwarden and Ayrault delved for this, Cortlandt, with
some difficulty, parted the mammoth's lips and examined the
teeth.  "From the conical projections on the molars," said he,
"this should be classed rather as a mastodon than as a mammoth."

When the huge heart was secured, Bearwarden arranged slices on
sharpened sticks, while Ayrault set about starting a fire.  He
had to use Cortlandt's gun to clear the dry wood of snakes,
which, attracted doubtless by the dead mastodon, came in such
numbers that they covered the ground, while huge pterodactyls,
more venomous-looking than the reptiles, hovered about the
opening above.

Arranging a double line of electric wires in a circle about the
mastodon and themselves, they sat down and did justice to the
meal, with appetites that might have dismayed the waiting throng.
Whenever a snake's head came in contact with one wire, while his
tail touched the other, he gave a spasmodic leap and fell back
dead.  If he happened to fall across the wires, lie immediately
began to sizzle, a cloud of smoke arose, and lie was reduced to
ashes.

"Any time that we are short of mastodon or other good game," said
Ayrault, "we need not hunger if we are not above grilled snake."

All laughed at this, and Bearwarden, drawing a whiskey-flask from
his pocket, passed it to his friends.

"When we rig our fishing-tackle," he continued, "and have fresh
fish for dinner, an entree of rattlesnake, roast mastodon for the
piece de resistance, and begin the whole with turtle soup and
clams, of which there must be plenty on the ocean beach, we shall
want to stay here the rest of our lives."

"I suspect we shall have to," replied Ayrault "for we shall
become so like Thanksgiving turkeys that the Callisto's door will
be too small for us."

While they sat and talked, the flowers and plants about them
softly began their song, and, as a visual accompaniment, the
fire-flies they had not before noticed twinkled through the
forest.

"My goodness! " exclaimed Cortlandt, "how time goes here!  We
started to get breakfast, and now it's growing dark."

Hastily cutting some thick but tender slices from the mastodon,
and impaling them with the remains of the heart on a sharpened
stake, they took up the wires, and the battery that had been
supplying the current, and retraced their steps by the way they
had come.  Their rubber-lined cowhide boots protected them from
all but the largest snakes, and as these were for the most part
already enjoying their gorge, they trampled with impunity on
those that remained in their path.  When they had covered about
half the distance to the raft, a huge boa-constrictor, which they
had mistaken for a branch, fell upon Cortlandt, pinioning his
arms and bearing him to the ground.  Dropping their loads,
Bearwarden and Ayrault threw themselves upon the monster with
their hunting-knives with such vim that in a few seconds it beat
a hasty retreat, leaving, as it did so, a wake of phosphorescent
light.

"Are you hurt?" asked Bearwarden, helping him up.

"Not in the least," replied Cortlandt.  "What surprises me is
that I am not.  The weight of that boa-constrictor would be very
great on earth, and here I should think it would be simply
crushing."

Groping their way through the rapidly growing darkness, they
reached the raft without further adventure, and, once on the
lake, had plenty of light.  Two moons, one at three quarters and
the other full, shone brightly, while the water was alive with
gymnotuses and other luminous creatures.  Sitting and living upon
the cross-timbers, they looked up at the sky.  The Great Bear and
the north star had exactly the same relation to each other as
when seen from the earth, while the other constellations and the
Milky Way looked identically as when they had so often gazed at
them before, and some idea of the immensity of space was conveyed
to them.  Here was no change; though they had travelled three
hundred and eighty million miles, there was no more perceptible
difference than if the
