"The sea around us began to rise, and then suddenly the rise ceased. After studying the matter I concluded that a batholite was rising under this region, and that there was a chance that we might escape submergence through its influence."

"Pardon me," interrupted King Richard, "but Mr. Versál has already spoken of a 'batholite.' What does that mean?"

"I imagine," replied the professor, smiling, "that neither Mr. Versál nor I have used the term in a strictly technical sense. At least we have vastly extended and modified its meaning in order to meet the circumstances of our case.

"Batholite is a word of the old geology, derived, from a language which was once widely cultivated, Greek, and meaning, in substance, stone, or rock, 'from the depths.'

"The conception underlying it is that of an immense mass of plastic rock rising under the effects of pressure from the interior of the globe, forcing, and in part melting its way to the surface, or lifting up the superincumbent crust.

"Geologists had discovered the existence of many great batholites that had risen in former ages, and there were some gigantic ones known in this part of America."

"That," interposed Cosmo, "was the basis of my idea that the continents would rise again, only I supposed that the rise would first manifest itself in the Himalayan region.

"However, since it has resulted in the saving of so many lives here, I cannot say that my disappointment goes beyond the natural mortification of a man of science upon discovering that he has been in error."

"I believe," said Professor Pludder, "that at least a million have survived here in the heart of the continent through the uprising of the crust. We have made explorations in many directions, and have found that through all the Coloradan region people have succeeded in escaping to the heights.

"Since the water, although it began to rise again after the first arrest of the advance of the sea, never attained a greater elevation than about 7,500 feet as measured from the old sea-level contours, there must be millions of acres, not to say square miles, that are still habitable.
