He was cunning and wary, and a man of infinite resource. It was not long before he found out that the polar discovery had not been announced, but he also discovered from listening to the conversations of some of the workmen in the village, which he frequently visited in a guise very unlike his ordinary appearance, that something extraordinary had taken place in the Sardis Works, of which he had never heard. A great shaft had been sunk, the people said, by accident; Mr. Clewe had gone down it in a car, and it had taken him nearly three hours to get to the bottom. Nobody yet knew what he had discovered, but it was supposed to be something very wonderful.
The night after Rovinski heard this surprising news he was in the building which had contained the automatic shell. As active as a cat, he had entered by an upper window.
Rovinski spent the night in that building. He had with him a dark lantern, and he made the most thorough examination of the machinery at the mouth of the shaft. He was a man of great mechanical ability and an expert in applied electricity. He understood that machinery, with all its complicated arrangements and appliances, as well as if he had built it himself. In fact, while examining it, he thought of some very valuable improvements which might have been made in it. He knew that it was an apparatus for lowering the car to a great depth, and, climbing into the car, he examined everything it contained. Coming down, he noticed the grating, and he knew what it was for. He looked over the engines and calculated the strength of the chains on the windlasses. He took an impression of the lock of the trap-door, and when he went away in the very early hours of the morning he understood the apparatus which was intended to lower the car as well as any person who had managed it. He knew nothing about the shaft under the great door, but this he intended to investigate as thoroughly as he had investigated the machinery.
The next night he entered the building very soon after Cunningham had gone his rounds, and he immediately set to work to prepare for his descent into the shaft. He disconnected one of the engines, for he sneeringly said to himself that the other one was more than sufficient to lower and raise the car. He charged and arranged all the batteries and put in perfect working order the mechanism by which Clewe had established a connection between the car and the engines, using one of the chains as a conductor, so that he could himself check or start the engines if an emergency should render it necessary.
Then Rovinski, bounding around like a wild animal in a cage, took out a key he had brought with him, opened the trap-door, lifted it back, and gazed down. He could see a beautifully cut well, but that was all. But no matter how deep it was, he intended to go down to the bottom of it.
He started the engine and lowered the car to the ground. Then he looked up at a grating which hung above it and determined to make use of this protection. He could not lower it in the ordinary way after he had entered the car, but in fifteen minutes he had arranged a pulley and rope by which, after the car had gone below the surface, he could lower the grating to its place. He got in, started down into the dark hole, stopped the engine, lowered the grating, went down a little farther, and turned on the electric lights.
The descent of Rovinski was a succession of the wildest sensations of amazed delight. Stratum after stratum passed before his astonished eyes, and, when he had gone down low enough, he allowed himself the most extravagant expressions of ecstasy. His progress was not so regular and steady as that of Roland Clewe had been. He found that he had perfect control of the engine and car, and sometimes he went down rapidly, sometimes slowly, and frequently he stopped. As he continued to descend, his amazement at the wonderful depth of the shaft became greater and greater and his mind was totally unable to appreciate the situation. Still he was not frightened, and went on down.
At last Rovinski emerged into the cave of light. There he stopped, the car hanging some twenty or thirty feet above the bottom. He looked out, he saw the shell, he saw the vast expanse of lighted nothingness, he tried to imagine what it was that that mass of iron rested upon. If he had not seen it, he would have thought he had come out into the upper air of some bottomless cavern. But a great iron machine nearly twenty feet long could not rest upon air! He thought he might be dreaming; he sat up and shut his eyes; in a few minutes he would open them and see if he still saw the same incomprehensible things.
The downward passage of Rovinski had occupied a great deal more time than he had calculated for. He had stopped so much, and had been so careful to examine the walls of the shaft, that morning had now arrived in the upper world, and it was at this moment, as he sat with his eyes closed, that William Cunningham looked down into the mouth of the shaft.
Cunningham was an observing man, and that morning he had picked up a pin and stuck it in the lapel of his rough coat, but he had done this hastily and carelessly. The pin was of a recently invented kind, being of a light, elastic metal, with its head of steel. As Cunningham leaned forward the pin slipped out of his coat; it fell through one of the openings in the grating, and descended the shaft head downward.
