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.

Down, down he went. He looked at his watch; he had been in that car only an hour and a half. Was that possible? He had supposed he was almost at the bottom. Suddenly he thought of the people above, and of the telephone. Why had not some of them spoken to him? It was shameful! He instantly called Bryce, and his heart leaped with joy when he heard the familiar voice in his ear. Now he talked steadily on for more than an hour. He had his gardener called, and he told him all that he wanted done in the flower-beds. He gave many directions in regard to the various operations of the Works. Things had been put back a great deal of late. He hoped soon to have everything going on in the ordinary way. There were two or three inventions in which he took particular interest, and of these he talked at great length with Mr. Bryce. Suddenly, in the midst of some talk about hollow steel rods, he told Bryce to let the engines move faster; there was no reason why the car should go so slowly.

The windlasses moved with a little more rapidity, and Clewe now turned and looked at an indicator which was placed on the side of the car, a little over his head. This instrument showed the depth to which he had descended, but he had not looked at it before, for if there should be anything which would make him nervous it would be the continual consideration of the depth to which he had descended.

The indicator showed that he had gone down fourteen and one eighth miles. Clewe turned and sat stiffly in his seat. He glanced down and saw beneath him only an illuminated hole, fading away at the bottom. Then he turned to speak to Bryce, but to his surprise he could think of nothing to say. After that he lighted another cigar and sat quietly.

Some minutes passed—he did not know how many—and he looked down through the gratings at the floor of the car. The electric light streamed downward through a deep orifice, which did not fade away and end in nothing; it ended in something dark and glittering. Then, as he came nearer and nearer to this glittering thing, he saw that it was his automatic shell, lying on its side, but he could see only a part of it through the opening of the bottom of the shaft which he was descending. In an instant, as it seemed to him, the car emerged from the narrow shaft, and he seemed to be hanging in the air-at least there was nothing he could see except that great shell, lying some forty feet below him. But it was impossible that the shell should be lying on the air! He rang to stop the car.

“Anything the matter?” cried Bryce, almost at the same instant.

“Nothing at all,” Clewe replied. “It's all right, I am near the bottom.”

In a state of the highest nervous excitement, Clewe gazed about him. He was no longer in a shaft; but where was he? Look out on what side he would, he saw nothing but the light going out from his lamps, but which seemed to extend indefinitely all about him. There seemed to be no limit to his vision in any direction. Then he leaned over the side of his car and looked downward. There was the great shell directly under him, but under it and around it, extending as far beneath it as it extended in every other direction, was the light from his own lamps, and yet that great shell, weighing many tons, lay as if it rested upon the solid ground!
