And in the
first place, I will tell you that at the South Pole--probably not
precisely at the pole, but certainly within the sixth of a degree of
it--is a circular surface of absolutely white-hot, boiling lava, about
fifteen miles in diameter. This surface was, in ages past, as indicated
by surroundings, many times its present surface extent--say from seventy
to seventy-five miles across. No doubt the surface of the earth at the
Antarctic Pole had once cooled, and later become covered with water,
though with very shallow water--probably at some points by none, at
others by a depth of ten or fifteen feet. From some cause--and many
causes might be imagined--this earth-and-water surface of say two
hundred miles in circumference, sank into the interior of the earth, and
the boiling lava came to the surface. We can scarcely conceive of the
awful effect when the Antarctic Sea poured over the circumference of
this mass of boiling earth and metal.
"Now it must be considered that this boiling lava was not merely a great
surface of white-hot matter, in which case it would, relatively
speaking, soon have cooled. To flood its edges with an overflow of ten
feet of water would be comparable to running a film of water a hundredth
of an inch in depth over the top of a red-hot stove in which a large
fire continues to burn and constantly to renew the heat on its surface.
