before man appeared. But we see Jupiter is admirably suited
for those who have been developed somewhere else, and it would be an
awful shame if we allowed it to lie unimproved till it produces
appreciative inhabitants of its own, for we find more to admire in one
half-hour than its entire present population during its lifetime. Yet,
how magnificent this world is, and how superior in its natural state to
ours! The mountainous horns of these crescent-shaped continents
protect them and the ocean they enclose from the cold polar marine
currents, and in a measure from the icy winds; while the elevated
country on the horns near the equator might be a Garden of Eden, or
ideal resort. To be sure, the continents might support a larger
population, if more broken up, notwithstanding the advantage resulting
from the comparatively low mountains along the coasts, and the useful
winds. A greater subdivision of land and water, more great islands
connected by isthmuses, and more mediterraneans joined by straits,
would be a further advantage to commerce; but with the sources of power
at hand, the resistless winds and water-power, much increased in
effectiveness by their weight, the great tides when several moons are
on the same side, or opposite the sun, internal heat near the surface,
and abundant coal-supply doubtless already formed and also near the
surface, such small alterations could be made very easily, and would
serve merely to prevent our becoming rusty.

"As Jupiter's distance from the sun varies from 506,563,000 miles at
aphelion to only 460,013,000 at perihelion, this difference, in
connection with even the slight inclination of the axis, must make a
slight change in seasons, but as the inclination is practically
nothing, almost the entire change results from the difference in
distance. This means that the rise or fall in temperature is general
on every degree of latitude, all being warmed simultaneously, more or
less, as the planet approaches or departs from the sun. It means also
that about the same conditions that Secretary Deepwaters suggested as
desirable for the earth, prevail here, and that Jupiter represents,
therefore, about the acme of climate naturally provided. On account of
its rapid rotation and vast size, the winds have a tornado's strength,
but they are nothing at this distance from the sun to what they would
be if a planet with its present rate of rotation and size were where
Venus or even the earth
