In a moment, the room was cleared. Rikud stood alone. He cleared his throat and listened to the sound, all by itself in the stillness. What would have happened if they hadn't retired? But they always did things punctually like that, whenever the buzzer sounded. They ate with the buzzer, bathed in the health-rays with it, slept with it. What would they do if the buzzer stopped buzzing? This frightened Rikud, although he didn't know why. He'd like it, though. Maybe then he could take them outside with him to the big garden of the two viewports. And then he wouldn't be afraid because he could huddle close to them and he wouldn't be alone. * * * * * Rikud heard the throbbing again as he stood in the room of the machinery. For a long time he watched the wheels and cogs and gears spinning and humming. He watched for he knew not how long. And then he began to wonder. If he destroyed the wheels and the cogs and the gears, would the buzzer stop? It probably would, because, as Rikud saw it, he was clearly an "unauthorized person." He had heard the voice again upon entering the room. He found a metal rod, bright and shiny, three feet long and half as wide as his arm. He tugged at it and it came loose from the wires that held it in place. He hefted it carefully for a moment, and then he swung the bar into the mass of metal. Each time he heard a grinding, crashing sound. He looked as the gears and cogs and wheels crumbled under his blows, shattered by the strength of his arm. Almost casually he strode about the room, but his blows were not casual. Soon his easy strides had given way to frenzied running. Rikud smashed everything in sight. When the lights winked out, he stopped. Anyway, by that time the room was a shambles of twisted, broken metal. He laughed, softly at first, but presently he was roaring, and the sound doubled and redoubled in his ears because now the throbbing had stopped. He opened the door and ran through the little corridor to the smaller viewport. Outside he could see the stars, and, dimly, the terrain beneath them. But everything was so dark that only the stars shone clearly. All else was bathed in a shadow of unreality. Rikud never wanted to do anything more than he wanted to open that door. But his hands trembled too much when he touched it, and once, when he pressed his face close against the viewport, there in the darkness, something bright flashed briefly through the sky and was gone. Whimpering, he fled. * * * * * All around Rikud were darkness and hunger and thirst. The buzzer did not sound because Rikud had silenced it forever. And no one went to eat or drink. Rikud himself had fumbled through the blackness and the whimpering to the dining room, his tongue dry and swollen, but the smooth belt that flowed with water and with savory dishes did not run any more. The machinery, Rikud realized, also was responsible for food.
