If this world were empty, he must face it alone. He must feed himself and defend himself and find shelter for himself and, in time to come, contrive some way in which to clothe himself.
He lit a cigarette and tried to think, but all that he could think about was that he must go easy on the cigarettes, for the half pack was all he had and when those were gone, there would be no more.
An alien land — but not entirely alien, for it was Earth again, the old familiar Earth unscarred by the tools of Man. It had the air of Earth and the grass and sky of Earth, and even the wolves and buffalo were the same as old Earth had borne. Perhaps it was Earth. It looked for all the world like the primal Earth might have looked before it lay beneath Man's hand, before Man had caught and tamed it and bound it to his will, before Man had stripped and gutted it and torn all its treasures from it.
It was no alien land — no alien dimension into which the top had flung him, although, of course, it had not been the top at all. The top hadn't had anything to do with it. The top was simply something on which one focused one's attention, simply a hypnotic device to aid the mind in the job which it must do. The top had helped him come into this land, but it had been his mind and that strange otherness that was his which had enabled him to travel from old familiar Earth to this strange, primal place.
There was something he had heard or read…
He went searching for it, digging back into his brain with frantic mental fingers.
A new story, perhaps. Or something he had heard. Or something he had seen on television.
It came to him finally — the story about the man in Boston — a Dr. Aldridge, he seemed to remember, who had said that there might be more worlds than one, that there might be a world a second ahead of ours and one a second behind ours and another a second behind that and still another and another and another, a long string of worlds whirling one behind the other, like men walking in the snow, one man putting his foot into the other's track and the one behind him putting his foot in the same track and so on down the line.
An endless chain of worlds, one behind the other. A ring around the Sun.
He hadn't finished reading the story, he remembered; something had distracted him and he'd laid the paper down. Smoking the cigarette down to its final shred, he wished that he had read it all. For Aldridge might have been right. This might be the next world after the old, familiar Earth, the next link on an endless chain of earths.
He tried to puzzle out the logic of such a ring of worlds, but he gave it up, for he had no idea of why it should be so.
Say, then, that this was Earth No. Two, the next earth behind the original Earth which he had left behind. Say, then, that in topographical features the earths would resemble one another, not exactly like one another perhaps, but very close in their topography, with little differences here and there, each magnified in turn until probably a matter of ten earths back the change would become noticeable. But this was only the second earth and perhaps its features were but little changed, and on old Earth he had been somewhere in Illinois and this, he told himself, was the kind of land the ancient Illinois would have been.
As a boy of eight he had gone into a land where there had been a garden and a house in a grove of trees and maybe this was the very earth he had visited then. If that were so, the house might still be there. And in later years he had walked an enchanted valley and it, too, might have been this earth, and if that were true, then there was another Preston house on this very earth, exactly like the one which stood so proudly in the Earth of his childhood.
There was a chance, he told himself. A slim chance, but the only chance he had…
He'd head for the Preston house, toward the northwest, retracing on foot the many miles he had driven since leaving his boyhood home. He knew there was little reason to believe there'd be any Preston house, little reason to think anything other than that he was trapped in an empty, lonely world. But he shut his mind to reason, for this was the only hope he had.
He checked the sun and saw that it had climbed higher in the sky, and that meant that it was morning and not afternoon and by that he knew which was west, and that was all he needed.
He set off, striding down the hill, heading for the north-west, toward the one hope he had in all the world.
CHAPTER THIRTY-ONE
WELL before dark, he picked a camping site, a grove through which ran a stream.
He took off his shirt and tied it to the stick to form a crude seine, then went down to a small pool in the creek and after some experimenting found how to use the seine to the best advantage. At the end of an hour, he had five good-sized fish.
He cleaned the fish with his pocket knife and lit the fire with a single match and congratulated himself upon his woodsmanship.
He cooked one of the fish and ate it. It was not an easy thing to eat, for he had no salt and the cooking was very far from expert — part of the fish was singed by flame, part of the rest was raw. But he was ravenous and it didn't taste too bad until the edge was off his hunger. After that it was a hard job choking down the rest, but he forced himself to do it, for he knew that he faced hard days ahead and to get through them he must keep his belly filled.
By this time darkness had fallen and he huddled beside the fire. He tried to think, but he was too tired for thinking. He caught himself dozing as he sat.
He slept, awoke to find the fire almost out and the night still dark, built up the fire with cold sweat breaking out on him. The fire was for protection as well as warmth and cooking and on the day's march he had seen not only wolves, but bear as well, and once a tawny shape had run through one of the groves as he passed through, moving too fast for him to make out what it was.
He woke again and dawn was in the sky. He built up the fire and cooked the rest of the fish. He ate one and then part of another, tucked the others, messy as they were, into his pocket. He would need food, he knew, throughout the day, and he did not want to waste the time to stop and make a fire.
He hunted around the grove and found a stout, straight stick, tested it with his weight and knew that it was sound. It would serve him for a walking staff and might be of some use as a club if he were called upon to defend himself. He checked his pockets to see that he was leaving nothing behind. He had his pocket knife and the matches and they were the important things. He wrapped the matches carefully in his handkerchief, then took off his undershirt and added it to the handkerchief. If he were caught in rain or fell in crossing a creek, the wrappings might help to keep the matches dry. And he needed those matches. He doubted very seriously that he could make fire with struck flint or by the Boy Scout bow and arrow method.
He was off before the sun was up, slogging northwestward, but going slower than he had gone the day before, for now he realized that it was not speed, but stamina that counted. To wear himself out in these first few days of hiking would be silly.
He lost some time making a wide detour in the afternoon around a fair-sized herd of buffalo. He camped that night in another grove, having stopped an hour or so earlier beside a stream to catch another supply of fish with his shirt-and-staff seine. In the grove he found a few bushes of dewberries, with some fruit still on them, so he had dessert as well as fish.
The sun came up and he moved on again. The sun descended.
And another day began and he went on. And another and another.
He caught fish. He found berries. He found a deer that had been freshly killed, no doubt by some animal that his appearance had scared off. Hacking away with his pocket knife, he cut as many ragged hunks of venison as he could carry. Even without salt, the meat was a welcome change from fish. He even learned to eat a little of it raw, hacking off a mouthful and chewing it methodically as he walked along. He had to discard the last of the meat when it got so high that be couldn't live with it.
He lost track of time. He had no idea how many miles he had covered, now how far he might be from the place where he was heading, nor even if he could find it at
all.
His shoes broke open and he stuffed them with dried grass and bound them together with strips cut off his trouser legs.
One day he knelt to drink at a pool and in the glass-clear water saw a strange face staring back at him. With a shock he realized that it was his own face, that of a bearded man, ragged and dirty and with the lines of fatigue upon him.
The days came and went. He moved ahead, northwestward. He kept putting first one foot out and then the other, moving almost automatically. The sun burned him at first and the burn turned to a tan. He crossed a wide, deep river on a log. It took a long time to get across and once the log almost spun and spilled him, but he made it.
He kept going on. There was nothing else to do.
He walked through an empty land, with no sign of habitation, although it was a land that was well suited for human occupation. The soil was rich and the grass grew tall and thick and the trees, which sprang skyward from groves along the watercourses, were straight and towered high into the sky.
Then one day, just before sunset, he topped a rise and saw the land fall away beneath his feet, sweeping downward toward the far-off ribbon of a river that he thought he recognized.
But it was not the river which held his attention, but the flash of setting sun on metal, on a large area of metal far down the sloping land.
He put up his hand and shielded his eyes against the sunlight and tried to make out what it was, but it was too far far away and it shone too brightly.
Climbing down the slope, not knowing whether to be glad or frightened, Vickers kept a close watch on the gleam of far-off metal. At times he lost sight of it when he dipped into the swales, but it was always there when he topped the rise again, so he knew that it was real.
Finally he was able to make out that what he saw were buildings — metallic buildings glinting in the sun, and now he saw that strange shapes came and went in the air above them and that there was a stir of life around them.
But it was not a city or a town. For one thing, it was too metallic. And for another, there were no roads leading into it.
As he came nearer, he made out more and more of the detail of the place and finally, when he was only a mile or two away, he stopped and looked at it and knew what it was.
It was not a city, but a factory, a giant, sprawling factory and to it came, continually, the strange flying things that probably were planes, but looked more like flying boxcars. The most of them came from the north and west and they came flying low, not too fast, dipping down to land in an area behind a screen of buildings that stood between him and the landing field.
And the creatures that moved about among the buildings were not men — or did not seem to be men, but something else, metallic things that flashed in the last rays of the sun.
All about the buildings, standing on great towers, were cup-shaped discs many feet across and all the faces of the discs were turned toward the sun and the faces of the discs glowed as if there were fires inside of them.
He walked slowly toward the buildings and as he came closer to them he realized for the first time the sheer vastness of them. They covered acre after acre and they towered for many stories high and the things that ran among them on their strange and many errands were not men, nor anything like men, but self-propelled machines.
Some of the machines he could identify, but most of them he couldn't. He saw a carrying machine rush past with a load of lumber clutched within its belly and a great crane lumbered past at thirty miles an hour with its steel jaws swinging. But there were others that looked like mechanistic nightmares and all of them went scurrying about, as if each of them were in a terrific hurry.
He found a street, or if not a street, an open space between two buildings, and went along it, keeping close to the side of one of the buildings, for it would have been what one's life was worth to walk down the center, where the machines might run one down.
He came to an opening in the building, from which a ramp led out to the street, and he cautiously climbed the ramp and looked inside. The interior was lighted, although he could not see where the light came from, and he looked down long avenues of machinery, busily at work. But there was no noise — that, he knew now, was the thing that bothered him. Here was a factory and there was no noise. The place was utterly silent except for the sound of metal on the earth as the self-propelled machines flashed along the Street.
He left the ramp and went down the street, hugging the building, and came out on the edge of the airfield where the aerial boxcars were landing and taking off.
He watched the machines land and disgorge their freight, great piles of shining, newly-sawed lumber, which was at once snatched up by the carrying machines and hustled off in all directions; great gouts of raw ore, more than likely iron, dumped into the maw of other carrying machines that looked, or so Vickers thought, like so many pelicans.
Once the boxcar had unloaded it took off again — took off without a single sound, as if a wind had seized and wafted it into the upper air.
The flying things came in endless streams, disgorging their endless round of cargo, which was taken care of almost immediately. Nothing was left piled up. By the time the machine had lifted into the air, the cargo it had carried had been rushed off somewhere.
Like men, thought Vickers — those machines act just like men. Their operation was not automatic, for to have been automatic each operation must have been performed at a certain place and at a regular time — and each ship did not land in exactly the same place, nor was the time of their arrival spaced regularly. But each time that a ship landed the appropriate carrying machine would be on hand to take charge of the cargo.
Like intelligent beings, Vickers thought, and even as he thought of it, he knew that that was exactly what they were.
Here, he knew, were robots, each one designed to take care of its own particular task. Not the man-like robots of one's imagination, but practical machines with intelligence and purpose.
The sun had set and as he stood at the corner of the building he looked up at the towers which had faced the sun. The discs atop the towers, he saw, were slowly turning back toward east, so that when the sun came up next morning they would be facing it.
Solar power, thought Vickers — and where else had he heard of solar power? Why, in the mutant houses! The dapper little salesman had explained to him and Ann how, when you had solar plant, you could dispense with public utilities.
And here again was solar power. Here, too, were frictionless machines that ran without the faintest noise. Like the Forever car that would not wear out, but would last through many generations.
The machines paid no attention to him. It was as if they did not see him, did not suspect he was there. Not a single one of them faltered as they rushed past him, not a single one had moved out of its way to give him a wider berth. Nor had any made a threatening motion toward him.
With the going of the sun, the area was lighted, but once again he could not determine the source of the light. The fall of night did not halt the work. The flying boxcars, great, angular, box-like contraptions, still came flying in, unloaded and flew off again. The machines kept up their scurrying. The long lines of machines within the buildings kept up their soundless labor.
The flying boxcars, he wondered, were they robots, too? And the answer seemed to be that they probably were.
He wandered about, hugging the building to keep out of the way.
He found a mighty loading platform, where the boxes were piled high, carried there by machines, loaded into the flying boxcars by machines, steadily going out to their destination, wherever it might be. He edged his way onto the platform and looked at some of the boxes closely, trying to determine what it was they held, but the only designations on them were stenciled code letters and numerals. He thought of prying some of them open, but he had no tools to do it, and he was just a bit afraid to do it, for while the machines continued to pay no attention to him, they might pay disastrous attention if he interfe
red.
Hours later he came out on the other side of the sprawling factory area and walked away from it, then turned back and looked at it and saw it glowing with its strange light and sensed the bustle of it.
He looked at the factory and wondered what was made there and thought he could guess. Probably razor blades and lighters and maybe light bulbs and perhaps the houses and the Forever cars. Maybe all of them.
For this, he felt certain, was the factory, or at least one of the factories, that Crawford and North American Research had been looking for and had failed to find.
No wonder, he thought, that they had failed to find it.
CHAPTER THIRTY-TWO
HE came to the river late in the afternoon, a river filled with tree-covered, grape-vined islands, clogged with sandbars and filled with wicked gurgling and the hiss of shifting sands and it could be, he was sure, no other stream than the Wisconsin River, flowing through its lower reaches to join the Mississippi. And if that were so, he knew where he was going. From here he could reach the place where he was going.
Now he feared he would not find the place he sought, that in this land there was no Preston house. Rather, he had fallen upon a strange land where there were no men, but robots, a complex robotic civilization in which Man played no part. There were no men connected with the factory, he was sure, for the place had been too self-sufficient, too sure of its purpose to need the hand or the brain of Man.
As the last daylight faded, he camped on the river's shore, and sat for a long time before he went to sleep, staring out over the silvered mirror of the moonlit water, feeling the loneliness strike into him, a deeper, more bitter loneliness than he'd ever known before.
When morning came, he'd go on; he'd tread the trail to its dusty end. He'd find the place where the Preston house should stand and when he found that there was no house — what would he do then?
