"And yet you talk of saving the race!" exclaimed the Frenchman with another bitter laugh.
"I do," replied Cosmo, "and it will be done."
"But how?"
"Through the re-emergence of land."
"That recalls our former conversation," put in Professor Abel Able. "It appears to me impossible that, when the earth is once covered with a universal ocean, it can ever disappear or materially lower its level. Geological ages would be required for the level of the water to be lowered even a few feet by the escape of vapor into space."
"No," returned Cosmo Versál, "I have demonstrated that that idea is wrong. Under the immense pressure of an ocean rising six miles above the ancient sea level the water will rapidly be forced into the interstices of the crust, and thus a material reduction of level will be produced within a few years—five at the most. That will give us a foothold. I have no doubt that even now the water around us is slightly lowering through that cause.
"But in itself that will not be sufficient. I have gone all over this ground in my original calculations. The intrusion of the immense mass of ocean water into the interior of the crust of the earth will result in a grand geological upheaval. The lands will re-emerge above the new sea level as they emerged above the former one through the internal stresses of the globe."
The scientific men present listened with breathless interest, but some of them with many incredulous shakings of the head.
"You must be aware," continued Cosmo, addressing them particularly, "that it has been demonstrated that the continents and the great mountain ranges are buoyed up, and, as it were, are floating somewhat like slags on the internal magma. The mean density of the crust is less under the land and the mountains than under the old sea-beds. This is especially true of the Himalayan region.
"That uplift is probably the most recent of all, and it is there, where at present the highest land of the globe exists, that I expect that the new upheaval will be most strongly manifested. It is for that reason, and not merely because it is now the highest part of the earth, that I am going with the Ark to Asia."
