He made his way to the bench, and collected three of the wound wire coils, which he dropped to the floor. With a cutting tool that he found he managed to get a length of wire from the large roll. The tool was very heavy. Next, he crawled to the corner, and selected a number of small pieces of metal. He rested for a while, studying the light bulb which hung in the center of the room. From the light it gave and the size of the filament, he roughly estimated the power of the current. Then, with a graphite writing instrument that he had found, he drew a diagram on the floor. He took a very long time doing this, and labeled it carefully. When he had finished, the little window at the end of the room showed that dawn was breaking outside. Hurriedly then, he set to work with the metal, the coils, and the wire,--twisting, winding, connecting and cross-connecting--constantly glancing at his diagram and at the window. Finally, when it was broad daylight outside, he gave a sigh of satisfaction. He had achieved an ugly, jumbled apparatus, vaguely cylindrical in shape with a point of metal at one end. He laid it on the floor; and making his way to the bench, secured two more lengths of wire. He crawled under the bench to where the power line for the light ran down the wall, and there connected them. Then, securing his cup of water, he dipped into it the ends of his two wires, and observed them for a moment. Satisfied, he carried them to his cylindrical apparatus, and connected one of them at the end opposite the metal point. The other he did not immediately connect. CHAPTER IV. The Circus He was breathing hard now, and his face was flushed. For a long time he sat very still and listened, but he heard no sound. At last, moving very slowly, he carried his cylinder to the door. He raised it, and placed the point against the metal lock, under the knob. He pressed his lips tightly together, and set his jaw.... With the end of the wire which he had not connected he touched a point on the cylinder. There was no sound. There was no movement of the cylinder. Yet the metal lock dissolved, and daylight shot through the place where it had been. A cloud of light grey dust drifted lazily to the floor. He disconnected the wires. Carefully he hid the thing under the cushions of his bed. Then he pushed open the door, and crawled out into the sunlight. The sun felt warm and pleasant on his back. He heard a cry, and looked up fearfully. One of the men of Toon was running towards him carrying a dish. It was the man that brought his food. His throat was tight, and he was trembling. He knew that this was the supreme moment. He nodded his head and smiled. He raised one hand, palm upward. The man stopped directly in front of him, and growled--then raised an arm, pointing at the door of his prison.
