We find analogous views about the origin of rivers. It is thought
that the water is raised by the sun and descends in rain and gathers
below the earth and so flows from a great reservoir, all the rivers
from one, or each from a different one. No water at all is generated,
but the volume of the rivers consists of the water that is gathered
into such reservoirs in winter. Hence rivers are always fuller in
winter than in summer, and some are perennial, others not. Rivers
are perennial where the reservoir is large and so enough water has
collected in it to last out and not be used up before the winter rain
returns. Where the reservoirs are smaller there is less water in the
rivers, and they are dried up and their vessel empty before the fresh
rain comes on.

But if any one will picture to himself a reservoir adequate to the
water that is continuously flowing day by day, and consider the amount
of the water, it is obvious that a receptacle that is to contain all
the water that flows in the year would be larger than the earth, or,
at any rate, not much smaller.

Though it is evident that many reservoirs of this kind do exist in
many parts of the earth, yet it is unreasonable for any one to refuse
to admit that air becomes water in the earth for the same reason as
it does above it. If the cold causes the vaporous air to condense
into water above the earth we must suppose the cold in the earth to
produce this same effect, and recognize that there not only exists
in it and flows out of it actually formed water, but that water is
continually forming in it too.
