cattle."

      He panted. His chest muscles contracted with the rest, so that his breathing was interfered with. But Murgatroyd, who'd been made uneasy and uncomfortable before Calhoun noticed anything wrong, was now bright and frisky. Medication had desensitized his muscles to outside stimuli. He would be able to take a considerable electric shock without responding to it.

      But he could be killed by one that was strong enough.

      A savage anger filled Calhoun. Everything fitted together. Allison had put his hand convenient to his blaster when Calhoun mentioned Texia. It meant that Calhoun suspected what Allison knew to be true. A cattle-fence unit had been set up on Maya, and it was holding—like cattle—the people it had previously driven—like cattle. Calhoun could deduce with some precision exactly what had been done. The first experience of Maya with the cattle fence would have been very mild. It would have been low-power, causing just enough uneasiness to be noticed. It would have moved from west to east, slowly, and it would have reached a certain spot and there faded out. And it would have been a mystery and an uncomfortable thing, and nobody would understand it on Maya. In a week it would almost be forgotten. But then there'd come a stronger disturbance. And it would travel like the first one; down the length of the peninsula on which the colony lay, but stopping at the same spot as before, and then fading away to nothingness. And this also would have seemed mysterious. But nobody would suspect humans of causing it. There would be theorizing and much questioning, but it would be considered an unfamiliar natural event.

      Probably the third use of the cattle fence would be most disturbing. This time it would be acutely painful. But it would move into the cities and through them and past them, and it would go down the peninsula to where it had stopped and faded on two previous occasions.

      The people of Maya would be disturbed and scared. But they considered that they knew it began to the westward of Maya City, and moved toward the east at such-and-such a speed, and it went so far and no farther. And they would organize themselves to apply this carefully worked out information.

      It would not occur to any of them that they had learned how to be driven like cattle.

      Calhoun, of course, could only reason that this must have happened. But nothing else could have taken place. Perhaps there were more than three uses of the moving cattle fence to get the people prepared to move past the known place at which it always faded to nothingness. They might have been days apart, or weeks apart, or months. There might have been stronger manifestations followed by weaker ones and then stronger ones again.

      But there was an inductive cattle fence across the highway here. Calhoun had driven into it. Every two seconds the muscles of his body tensed. Sometimes his heart missed a beat at the time that his breathing stopped, and sometimes it pounded violently. It seemed that the symptoms became more and more unbearable.

      He got out his med kit, with hands that spasmodically jerked uncontrollably. He fumbled out the same medication he'd given Murgatroyd. He took two of the pellets.

      "In reason," he said coldly, "I ought to let you take what this damned thing would give you. But—here!"

      Allison had panicked. The idea of a cattle fence suggested discomfort, of course, but it did not imply danger. The experience of a cattle fence, designed for huge hoofed beasts instead of men, was terrifying. Allison gasped. He made convulsive movements. Calhoun himself moved erratically. For one and a half seconds 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?"
