The seafloor kept sinking, and its significantly steeper slope took us to greater depths. It must have been nearly three o’clock when we reached a narrow valley gouged between high, vertical walls and located 150 meters down. Thanks to the perfection of our equipment, we had thus gone ninety meters below the limit that nature had, until then, set on man’s underwater excursions. I say 150 meters, although I had no instruments for estimating this distance. But I knew that the sun’s rays, even in the clearest seas, could reach no deeper. So at precisely this point the darkness became profound. Not a single object was visible past ten paces. Consequently, I had begun to grope my way when suddenly I saw the glow of an intense white light. Captain Nemo had just activated his electric device. His companion did likewise. Conseil and I followed suit. By turning a switch, I established contact between the induction coil and the glass spiral, and the sea, lit up by our four lanterns, was illuminated for a radius of twenty-five meters. Captain Nemo continued to plummet into the dark depths of this forest, whose shrubbery grew ever more sparse. I observed that vegetable life was disappearing more quickly than animal life. The open-sea plants had already left behind the increasingly arid seafloor, where a prodigious number of animals were still swarming: zoophytes, articulates, mollusks, and fish. While we were walking, I thought the lights of our Ruhmkorff devices would automatically attract some inhabitants of these dark strata. But if they did approach us, at least they kept at a distance regrettable from the hunter’s standpoint. Several times I saw Captain Nemo stop and take aim with his rifle; then, after sighting down its barrel for a few seconds, he would straighten up and resume his walk. Finally, at around four o’clock, this marvelous excursion came to an end. A wall of superb rocks stood before us, imposing in its sheer mass: a pile of gigantic stone blocks, an enormous granite cliffside pitted with dark caves but not offering a single gradient we could climb up. This was the underpinning of Crespo Island. This was land. The captain stopped suddenly. A gesture from him brought us to a halt, and however much I wanted to clear this wall, I had to stop. Here ended the domains of Captain Nemo. He had no desire to pass beyond them. Farther on lay a part of the globe he would no longer tread underfoot.
