He passed over the shoreline at a height of five hundred feet. There was a short stretch of sand, some woods, and then a long expanse of green that must be grass. He eased the control forward, then back again. The little ship came skimming down at two hundred miles an hour. Its skids touched the surface, and it bounded upward. Sam fought the controls to keep it from nosing over. Again it touched, jerking with deceleration. This time it seemed to have struck right. Then a hummock of ground caught against one skid. The craft slithered sideways and flipped over. Sam braced himself as the ship began coming to pieces around him. He pulled himself out, staring at the wreckage. It was a shame that it was ruined, he thought. But it couldn’t be made as strong as he was and still glide through the air.
He turned to study the world around him. The grass was knee-high, moving gently in the wind. Beyond it lay woods. Sam had seen only pictures of trees like that before. He moved toward them, noticing the thickness of the underbrush around them. Below them, the dirt was dark and moist. He lifted a pinch to his face, moving his smell receptors forward in his mouth slit. It was a rich smell, richer than the stuff in the hydroponic tanks. He lifted his head to look for the birds he expected, but he could see no sign of them. There were only insects, buzzing and humming.
The sun had already set, he noticed. Yet it was not yet dark. There was a paling of the light, and a soft diffusion. He shook his head. Above him, tiny twinkling spots began to appear. He had read that the stars twinkled, but he had thought it only fiction. He had never been under the open sky of Earth before.
Then a soft murmur of sound reached him. He started away, to be drawn back to it. Slowly he realized it was a sound like the description of that heard near the sea. He had never seen an ocean, either. And now one lay no more than a mile away.
He stumbled through the woods in the growing darkness. For some reason, he was reluctant to turn on his lights. Eventually, he learned to make his way through the brush and around the trees. The sound grew louder as he progressed.
It was dark when he reached the seashore, but there was a hint of faint light to the east. As he watched, it increased. A pale white arc appeared over the horizon and grew to a large circle. The Moon, he realized finally.
The waves rose and fell, booming into surf. And far out across the sea, the Moon seemed to ride on the waves, casting a silver road of light over the water.
Sam had remembered a word. Now for the first tune, he found an understanding of it. This was Beauty.
He sighed as he heaved himself from the sand and began heading along the shore in search of a road that would take him westward. No wonder men wanted to come back to defend a world where something like this could be seen.
The Moon rouse higher as he moved on, its light now bright enough to give him clear vision. He came over a small rise in the ground and spotted what seemed to be a road beyond it. Beside the road was a house. It was dark and quiet, but he swung aside, going through a copse of woods to reach it and search for any evidence of humanity.
The windows were mostly broken, he saw as he approached. And weeds had grown up around it. There was a detached building beside it that held a small car, by what he could see from the single dusty window. He skirted that and reached the door of the house; it opened at his touch, its hinges protesting rustily.
Inside, the moonlight shone through the broken windows on a jumble of furniture that was overturned and tossed about in no order Sam could see. And there were other things—white things that lay sprawled on the floor.
He recognized them from the pictures in the books—skeletons of human beings. Two smaller skeletons were tangled in one corner with their skulls bashed in. A large skeleton lay near them, with the rusty shape of a knife shoved through a scrap of clothing between two ribs. There was a revolver near one hand. Across the room, a skeleton in the tatters of a dress was a jumbled pile of bones, with a small hole in the skull that could have come from a bullet.
Sam backed out of the room. He knew the meaning of another word now. He had seen Madness.
Men had learned to build good machines. The car motor barely turned over after Sam had figured out the controls, but it caught and began running with only a slight sputtering. The tires were slightly soft, but they took the bumps of the rutted little trail. Later, when Sam found a better road, they lasted under the punishment of high speed. Most of the road was clear. There were few vehicles along its way, and most of those seemed to have drifted to the shoulder before they stopped or crashed.
The sun was just rising when Sam located the place where the factory and warehouse had served as a legitimate cover for the secret underground robot project. Fire and weather had left only gutted ruins and rusty things that had once been machines. But the section that housed the creche entrance now stood apart from the rest, almost unharmed.
Sam moved into it and to the metal door openly concealed among other such doors. He should probably not have known the combination, but men were often careless around robots, and he had been curious enough to note and remember the details. He bent to what seemed to be an ornamental grille and called out a series of numbers.
The door seemed to stick a little, but then it moved aside. Beyond lay the elevator,- and that operated smoothly at the combination he punched. Power was still on, at least. There was no light, but the bulbs sprang into Life as he found a switch.
He called out once, but he no longer expected to find men so easily. The place had the feel of abandonment. And while it could have protected its workers from almost anything, there had been only enough food and water stocked here for two weeks. There were a few signs that it had been used for a shelter, but most of it was in good order.
He moved back past offices and laboratories toward the rear. The real creche, with its playrooms and learning devices, was empty, he saw. No robots had been receiving postawakening training. Sam was not surprised. He knew that most of the work here had been devoted to exploring the possibilities of robots, with the actual construction only a necessary sideline. Usually, the brain complexes had been created and tested without bodies, and then extinguished before there had been a full awakening.
He started toward the educator computer out of his old habits. But it was only a machine that had programmed his progress from prepared tapes and memory circuits. It could not help him now.
Beyond the creche lay the heart of the whole affair.
Here the brain complexes were assembled from components according to Jfesoteric calculations or to meet previously recorded specifications. This was work that required a computer that was itself intelligent to some extent. It had to make sense out of the desirable options given it by men and then form the brain paths needed, either during construction or during the initial period before awakening. Everything that Sam had been before awakening had come from this, with only the selection of his characteristics chosen by men. That pattern would still be recorded, along with what the great computer had learned of him during his previous return here.
Sam moved toward the machine, gazing in surprise at the amount of work lying about. There were boxes of robot bodies crammed into every storage space. They could never have been assembled in such numbers here. And beyond lay shelves jammed with the components for the brain complexes. With such quantities, enough robots could be made to supply the Lunar Base needs for generations.
The computer itself was largely hidden far below, but its panel came to life at his touch. It waited.
“This is Robot Twelve, Mark One,” Sam said. “You have authorization on file.”
