Jules Verne: Twenty Thousand Leagues Under the Seas

SECOND PART CHAPTER 10: The Underwater Coalfields (continued)

I wasn't sure what to think, when a voice said to me:

"Is that you, professor?"

"Ah, Captain Nemo!" I replied. "Where are we?"

"Underground, professor."

"Underground!" I exclaimed. "And the Nautilus is still floating?"

"It always floats."

"But I don't understand!"

"Wait a little while. Our beacon is about to go on, and if you want some light on the subject, you'll be satisfied."

I set foot on the platform and waited. The darkness was so profound I couldn't see even Captain Nemo. However, looking at the zenith directly overhead, I thought I caught sight of a feeble glimmer, a sort of twilight filtering through a circular hole. Just then the beacon suddenly went on, and its intense brightness made that hazy light vanish.

This stream of electricity dazzled my eyes, and after momentarily shutting them, I looked around. The Nautilus was stationary. It was floating next to an embankment shaped like a wharf. As for the water now buoying the ship, it was a lake completely encircled by an inner wall about two miles in diameter, hence six miles around. Its level--as indicated by the pressure gauge--would be the same as the outside level, because some connection had to exist between this lake and the sea. Slanting inward over their base, these high walls converged to form a vault shaped like an immense upside-down funnel that measured 500 or 600 meters in height. At its summit there gaped the circular opening through which I had detected that faint glimmer, obviously daylight.

Before more carefully examining the interior features of this enormous cavern, and before deciding if it was the work of nature or humankind, I went over to Captain Nemo.

"Where are we?" I said.
