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 gl
