The door of the shaft was removed, the car which had hung high above it was lowered to the mouth of the opening, and Roland stepped within it and seated himself. Above him and around him were placed geological tools and instruments of many kinds; a lantern, food and drink; everything, in fact, which he could possibly be presumed to need upon this extraordinary journey. A telephone was at his side by which he could communicate at any time with the surface of the earth. There were electric bells; there was everything to make his expedition safe and profitable. When he gave the word to start the engines, there were no ceremonies, and nothing was said out of the common. When the conical top of the car had descended below the surface, a steel grating, with orifices for the passage of the chains, was let down over the mouth of the shaft, and the downward journey was begun. In the floor of the car were grated openings, through which Clewe could look downward; but although the shaft below him was brilliantly illuminated by electric lights placed under the car, it did not frighten him or make him dizzy to look down, for the aperture did not appear to be very far below him. The upper part of the car was partially open, and bright lights shone upon the sides of the shaft. As he slowly descended, he could see the various strata appearing and disappearing in the order in which he knew them. Not far below the surface he passed cavities which he believed held water; but there was no water in them now. He had expected these, and had feared that upon their edges there might be loosened patches of rock or soil, but everything seemed tightly packed and hard. If anything had been loosened it had gone down already. Down, down he went until he came to the eternal rocks, where the inside of the shaft was polished as if it had been made of glass. It became warmer and warmer, but he knew that the heat would soon decrease. The character of the rocks changed, and he studied them as he went down, and continually made notes. After a time the polished rocky sides of the shaft grew to be of a solemn sameness. Clewe ceased to take notes; he lighted a cigar and smoked. He tried to quietly imagine what he would come to when he got to the bottom; it would be some sort of a cave into which his shell had made an opening. He wondered what sort of a cave it would be, and how high the roof of it was from the bottom. He wondered if his gardener had remembered what he had told him about the flower-beds in front of his house; he wanted certain changes made which Margaret had suggested. He tried to keep his mind on the flower-beds, but it drifted away to the cave below. He began to wonder if he would come to some underground body of water where he would be drowned; but he knew that was a silly thought. If the shaft had gone through subterranean reservoirs, the water of these would have run out, and before they reached the bottom of the shaft would have dissipated into mist.
