“I agree with you; but I repeat, Conseil, this phenomenon will never happen. The violence of subterranean force is ever diminishing. Volcanoes, so plentiful in the first days of the world, are being extinguished by degrees; the internal heat is weakened, the temperature of the lower strata of the globe is lowered by a perceptible quantity every century to the detriment of our globe, for its heat is its life.”
“But the sun?”
“The sun is not sufficient, Conseil. Can it give heat to a dead body?”
“Not that I know of.”
“Well, my friend, this earth will one day be that cold corpse; it will become uninhabitable and uninhabited like the moon, which has long since lost all its vital heat.”
“In how many centuries?”
“In some hundreds of thousands of years, my boy.”
“Then,” said Conseil, “we shall have time to finish our journey—that is, if Ned Land does not interfere with it.”
And Conseil, reassured, returned to the study of the bank, which the Nautilus was skirting at a moderate speed.
During the night of the 16th and 17th February we had entered the second Mediterranean basin, the greatest depth of which was 1,450 fathoms. The Nautilus, by the action of its crew, slid down the inclined planes and buried itself in the lowest depths of the sea.
