Jules Verne: Twenty Thousand Leagues Under the Seas

SECOND PART CHAPTER 7: The Mediterranean in Forty-Eight Hours (continued)

"But with all due respect to master," Conseil ventured to observe, "it's like an actual isthmus connecting Europe to Africa."

"Yes, my boy," I replied, "it cuts across the whole Strait of Sicily, and Smith's soundings prove that in the past, these two continents were genuinely connected between Cape Boeo and Cape Farina."

"I can easily believe it," Conseil said.

"I might add," I went on, "that there's a similar barrier between Gibraltar and Ceuta, and in prehistoric times it closed off the Mediterranean completely."

"Gracious!" Conseil put in. "Suppose one day some volcanic upheaval raises these two barriers back above the waves!"

"That's most unlikely, Conseil."

"If master will allow me to finish, I mean that if this phenomenon occurs, it might prove distressing to Mr. de Lesseps, who has gone to such pains to cut through his isthmus!"

"Agreed, but I repeat, Conseil: such a phenomenon won't occur. The intensity of these underground forces continues to diminish. Volcanoes were quite numerous in the world's early days, but they're going extinct one by one; the heat inside the earth is growing weaker, the temperature in the globe's lower strata is cooling appreciably every century, and to our globe's detriment, because its heat is its life."

"But the sun--"

"The sun isn't enough, Conseil. Can it restore heat to a corpse?"

"Not that I've heard."

"Well, my friend, someday the earth will be just such a cold corpse. Like the moon, which long ago lost its vital heat, our globe will become lifeless and unlivable."

"In how many centuries?" Conseil asked.

"In hundreds of thousands of years, my boy."
