segments. As soon as it was exposed, it began slowly shimmying away. Before it had gone two feet, it was crossed by a moving shadow. Guiding the shadow was a black wasp with an orange ring around the abdomen. It closed the gap between itself and the worm with a swift, smooth movement and straddled the dark body. Before the wasp could grasp the thick neck with its mandibles, the intended victim began rapidly rolling and unrolling and flinging itself from side to side. For a minute the delicate dancer above it could not succeed in clenching the neck. Its sharp jaws slid off the frenziedly jerking skin until the tiring creature paused for the chip of a second. Seizing opportunity and larva at the same time, the wasp stood high on its legs and pulled the worm's front end from the ground, exposing the yellowed band of the underpart. The attacker's abdomen curved beneath its own body; the stinger jabbed between two segments of the prey's jointed length. Instantly, the writhing stilled. A shudder, and the caterpillar became as inert as if it were dead. Jack had watched with an eye not completely clinical, feeling the sympathy of the hunted and the hounded for a fellow. His own struggles of the past few months had been as desperate, though not as hopeless, and ... He stopped thinking. His heart again took up the rib-thudding.

He put his hands against the weeds and pushed his body up. He looked into the silent mouth of a .38 automatic. It told him his running days were over. You didn't talk back to a mouth like that. II Jack was lucky. As one of the last to be herded into the truck, which had been once used for hauling cattle, he had more room to breathe than most of the others. He faced the rear bars. The vehicle was heading into the sun. Its rays were not as hard on him as on some of those who were so jam-packed they could not turn to get the hot yellow splotch out of their eyes. He looked through lowered lids at the youths on either side of him. For the last three days in the transie jungle, the one standing on his left had given signs of what was coming upon him, what had come upon so many of the transies. The muttering, the indifference to food, not
