"Yes, Axel; and judging by these ridges of foam, you may observe that the sea will rise about twelve feet."
"This is wonderful," I said.
"No; it is quite natural."
"You may say so, uncle; but to me it is most extraordinary, and I can hardly believe my eyes. Who would ever have imagined, under this terrestrial crust, an ocean with ebbing and flowing tides, with winds and storms?"
"Well," replied my uncle, "is there any scientific reason against it?"
"No; I see none, as soon as the theory of central heat is given up." "So then, thus far," he answered, "the theory of Sir Humphry Davy is confirmed."
"Evidently it is; and now there is no reason why there should not be seas and continents in the interior of the earth."
"No doubt," said my uncle; "and inhabited too."
"To be sure," said I; "and why should not these waters yield to us fishes of unknown species?"
"At any rate," he replied, "we have not seen any yet."
