pies only about one eighth of the surface, we
know, from the experience of the other planets, that this is bound to
increase; so that, if the human race can perpetuate itself on Jupiter
long enough, it will undoubtedly have one fourth or a larger proportion
for occupation, though the land already upheaved comprises fully forty
times the area of our entire globe, which, as we know, is still
three-fourths water."

"Since we have reached what we might call the end of Jupiter, and still
have time," continued Ayrault, "let us proceed to Saturn, where we may
find even stranger things than here. I hoped we could investigate the
great red spot, but am convinced we have seen the beginning of one in
Twentieth Century Archipelago, and what, under favourable conditions,
will be recognized as such on earth."

It was just six terrestrial weeks since they had set out, and therefore
February 2d on earth.

"It would be best, in any case, to start from Jupiter's equator," said
Cortlandt, "for the straight line we should make from the surface here
would be at right angles to Saturn. We shall probably, in spite of
ourselves, swing a few degrees beyond the line, and so can get a
bird's-eye view of some portion of the southern hemisphere."

"All aboard for Saturn!" cried Bearwarden enthusiastically, in his
jovial way. "This will be a journey."

CHAPTER XIV.

THE SCENE SHIFTS.

Having returned the rugs to the Callisto, they applied the maximum
power of the batteries to rising, closed all openings when the
barometer registered thirty, and moved off into space. When Several
thousand miles above the pole, they diverted part of the power to
attracting the nearest moon that was in the plane of Jupiter's equator,
and by the time their upward motion had ceased were moving well in its
direction. Their rapid motion aided the work of resisting gravity,
since their car had in fact become a small moon, revolving, like those
of Uranus or that of Neptune, in an orbit varying greatly from the
plane of the ecliptic. As they flew south at a height ranging from two
thousand to three thousand miles, the planet revolved before them, and
they had a chance of obtaining a thorough view. There were but a few
scattered islands on the side of the Northern hemisphere opposite to
that over which they had reached the pole, and in the varying colours
of the water, which they attributed to temperature or
