out of two, he could control his muscles. For half a second at a time, he could not. But he poked a pill into Allison's mouth.
"Swallow it!" he commanded. "Swallow!"
The ground-car rested tranquilly on the highway, which here went on for a mile and then dipped in a gentle incline and then rose once more. The totally level fields to right and left came to an end here. Native trees grew, trailing preposterously with long fronds. Brushwood hid much of the ground. That looked normal. But the lower, ground-covering vegetation was wilted and rotting.
Allison choked upon the pellet. Calhoun forced a second upon him. Murgatroyd looked inquisitively at first one and then the other of the two men. He said:
"Chee? Chee?"
Calhoun lay back in his seat, breathing carefully to keep alive. But he couldn't do anything about his heartbeat. The sun shone brightly, though now it was low, toward the horizon. There were clouds in the reddened sky. A gentle breeze blew. Everything, to outward appearance, was peaceful and tranquil and commonplace upon this small world.
But in the area that human beings had taken over there were cities which were still and silent and deserted, and somewhere—somewhere!—the population of the planet waited uneasily for the latest of a series of increasingly terrifying phenomena to come to an end. Up to this time the strange, creeping, universal affliction had begun at one place, and moved slowly to another, and then diminished and ceased to be. But this was the greatest and worst of the torments. And it hadn't ended. It hadn't diminished. After three days it continued at full strength at the place where previously it had stopped and died away.
The people of Maya were frightened. They couldn't return to their homes. They couldn't go anywhere. They hadn't prepared for an emergency to last for days. They hadn't brought supplies of food.
It began to look as if they were going to starve.

Calhoun was in very bad shape when the sports car came to the end of the highway.
First, all the multiple roadways of the route that had brought him here were joined by triple ribbons of road-surface from the north. For a space there were twenty-four lanes available to traffic. They flowed together, and then there were twelve. Here there was evidence of an enormous traffic concentration at some time now past. Brush and small trees were crushed and broken where cars had been forced to travel off the hard-surface roadways and through undergrowth. The twelve lanes dwindled to six, and the unpaved area on either side showed that innumerable cars had been forced to travel off the highway altogether. Then there were three lanes, and then two, and finally only a single ribbon of pavement where no more than two cars could run side by side. The devastation on either hand was astounding. All visible vegetation for half a mile to right and left was crushed and tangled. And then the narrow surfaced road ceased to be completely straight. It curved around a hillock—and here the ground was no longer perfectly flat—and came to an end.
And Calhoun saw all the ground-cars of the planet gathered and parked together.
There were no buildings. There were no streets. There was nothing of civilization but tens and scores of thousands of ground-cars. They were extraordinary to look at, stopped at random, their fronts pointed in all directions, their air-column tubes thrusting into the ground so that there might be trouble getting them clear again.
Parked bumper to bumper in closely placed lines, in theory twenty-five thousand cars could be parked on a square mile of ground. But there were very many times that number of cars here, and some places were unsuitable for parking, and there were lanes placed at random and there'd been no special effort to put the maximum number of cars in the smallest place. So the surface transportation system of the planet Maya spread out over some fifty sprawling square miles. Here, cars were crowded closely. There, there was much room between them. But it seemed that as far as one could see in the twilight there were glistening vehicles gathered confusedly, so there was nothing else to be seen but an occasional large tree rising from among them.
Calhoun came to the end of the surfaced road. He'd waited for the pellets he'd taken and given to Allison to have the effect they'd had on Murgatroyd. That had come about. He'd driven on. But the strength of the inductor field had increased to the intolerable. When he stopped the sports car he showed the effects of what he'd been through.
Figures on foot converged upon him instantly. There were eager calls.
"It's stopped? You got through? We can go back?"
Calhoun shook his head. It was just past sunset and many brilliant colorings showed in the western sky, but they couldn't put color into Calhoun's face. His cheeks were grayish and his eyes were deep-sunk, and he looked like someone in the last stages of exhaustion. He said heavily:
"It's still there. We came through. I'm Med Service. Have you got a government here? I need to talk to somebody who can give orders."

If he'd asked two days earlier there would have been no answer, because the fugitives were only waiting for a disaster to come to an end. One day earlier, he might have found men with authority busily trying to arrange for drinking water for something like two millions of people, in the entire absence of wells or pumps or ways of making either. And if he'd been a day later, it is rather likely that he'd have found savage disorder. But he arrived at sundown three days after the flight from the cities. There was no food to speak of, and water was drastically short, and the fugitives were only beginning to suspect that they would never be able to leave this place—and that they might die here.
Men left the growing crowd about the sports car to find individuals who could give orders. Calhoun stayed in the car, resting from the unbearable strain he'd undergone. The ground-inductor cattle fence had been ten miles deep. One mile was not bad. Only Murgatroyd had noticed it. After two miles Calhoun and Allison suffered; but the medication strengthened them to take it. But there'd been a long, long way in the center of the induction-field in which existence was pure torment. Calhoun's muscles defied him for part of every two-second cycle, and his heart and lungs seemed constantly about to give up even the pretense of working. In that part of the cattle-fence field, he'd hardly dared drive faster than a crawl, in order to keep control of the car when his own body was uncontrollable. But presently the field strength lessened and ultimately ended.
Now Murgatroyd looked cordially at the figures who clustered about the car. He'd hardly suffered at all. He'd had half as much of the medication as Calhoun himself, and his body weight was only a tenth of Calhoun's. He'd made out all right. Now he looked expectantly at what became a jammed mass of crowding men about the vehicle that had come through the invisible barrier across the highway. They hoped desperately for news to produce hope. But Murgatroyd waited zestfully for somebody to welcome him and offer him cakes and sweets, and undoubtedly presently a cup of coffee.
But nobody did.
It was a long time before there was a stirring at the edge of the crowd. Night had fully fallen then, and for miles and miles in all directions lights in the ground cars of Maya's inhabitants glowed brightly. They drew upon broadcast power, naturally, for their motors and their lights. Off to one side someone shouted. Calhoun turned on his headlights for a guide. More shoutings. A knot of men struggled to get through the crowd. With difficulty, presently, they reached the car.
"They say you got through," panted a tall man, "but you can't get back. They say—"
