and eyes capable of seeing clearly with less light? Reasoning by analogy, we can come to
no other conclusion, unless their advent is anticipated by the arrival of ready-made
colonists from the more advanced earth, like ourselves. In that case man, by pursuing the
same destructive methods that he has pursued in regard to many other species, may
exterminate the intervening links, and so arrest evolution."
Before leaving Deepwaters Bay they secured a pail of its water, which they found, on
examination, contained a far larger percentage of salt and solid material than the oceans
on earth, while a thermometer that they immediately immersed in it soon registered
eighty-five degrees Fahrenheit; both of which discoveries confirmed them in what they
already knew, namely, that Jupiter had advanced comparatively little from the condition
in which the water on the surface is hot, in which state the earth once was.
They were soon beyond the estuary at which they had stopped to study the forms of life
and to make this test, and kept on due north for several days, occasionally rising above
the air. As their familiarity with their surroundings increased, they made notes of several
things. The mountains covered far more territory at their bases than the terrestrial
mountains, and they were in places very rugged and showed vast yawning chasms. They
were also wooded farther up their sides, and bore but little snow; but so far the travellers
had not found them much higher than those on earth, the greatest altitude being the thirty-
two thousand feet south of Deepwaters Bay, and one other ridge that was forty thousand;
so that, compared with the size of the planet and its continents, they seemed quite small,
and the continents themselves were comparatively level. They also noted that spray was
blown in vast sheets, till the ocean for miles was white as milk. The wind often attained
tornado strength, and the whole surface of the water, about what seemed to be the storm
centre, frequently moved with rapidity in the form of foam. Yet, notwithstanding this, the
waves were never as large as those to which they were accustomed on earth. This they
accounted for very easily by the fact that, while water weighed 2.55 times as much as on
earth, the pressure of air was but little more than half as much again, and consequently its
effect on all but the very surface of the heavy liquid was comparatively slight.
"Gravity is a useful factor here," observed Cortlandt, as they made a note of this; "for, in
addition to giving immunity from waves, it is most effective in checking the elevation of
high mountains or table-lands in the high latitudes, which we shall doubtless find
sufficiently cool, or even cold, while in tropical regions, which might otherwise be too
hot, it interferes with them least, on account of being partly neutralized by the rapid
rotation with which all four of the major planets are blessed."
At sunrise the following morning they saw they were approaching another great arm of
the sea. It was over a thousand miles wide at its mouth, and, had not the photographs
showed the contrary, they would have thought the Callisto had reached the northern end
of the continent. It extended into the land fifteen thousand miles, and, on account of the
shape of its mouth, they called it Funnel Bay. Rising to a height, they flew across, and
came to a great table-land peninsula, with a chain of mountains on either side. The
southern range was something over, and the northern something less than, five thousand
feet in height, while the table-land between sloped almost imperceptibly towards the
