I say seventy-five fathoms, though I had no instrument by which to judge the distance. But I knew that even in the clearest waters the solar rays could not penetrate further. And accordingly the darkness deepened. At ten paces not an object was visible. I was groping my way, when I suddenly saw a brilliant white light. Captain Nemo had just put his electric apparatus into use; his companion did the same, and Conseil and I followed their example. By turning a screw I established a communication between the wire and the spiral glass, and the sea, lit by our four lanterns, was illuminated for a circle of thirty-six yards. Captain Nemo was still plunging into the dark depths of the forest, whose trees were getting scarcer at every step. I noticed that vegetable life disappeared sooner than animal life. The medusæ had already abandoned the arid soil, from which a great number of animals, zoophytes, articulata, molluscs, and fishes, still obtained sustenance. As we walked, I thought the light of our Ruhmkorff apparatus could not fail to draw some inhabitant from its dark couch. But if they did approach us, they at least kept at a respectful distance from the hunters. Several times I saw Captain Nemo stop, put his gun to his shoulder, and after some moments drop it and walk on. At last, after about four hours, this marvellous excursion came to an end. A wall of superb rocks, in an imposing mass, rose before us, a heap of gigantic blocks, an enormous, steep granite shore, forming dark grottos, but which presented no practicable slope; it was the prop of the Island of Crespo. It was the earth! Captain Nemo stopped suddenly. A gesture of his brought us all to a halt, and, however desirous I might be to scale the wall, I was obliged to stop. Here ended Captain Nemo’s domains. And he would not go beyond them. Further on was a portion of the globe he might not trample upon.
