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
