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!"
