<passage>:
He jumped into a bramble bush and scratched out both his eyes. And when he saw what he had done, with all his might and main when he arrived at the Hoffman Center that morning. Dorffman looked as though he'd been running all night. There were dark pouches under his eyes his heavy unshaven face seemed to sag at every crease. Lessing sniffing out with a sigh. "All right, Jack—what's wrong?" "This kid is driving me nuts," said Dorffman through clenched teeth. "He's gone completely hay-wire. Nobody's been able to get near him for three weeks, and now at six o'clock this morning he decides he's leaving the Farm. I talk to him, I sweat him down, I do everything but tie him to the bed, and I waste my time. He's leaving the Farm. Period." "So you bring him down here," said Lessing sourly. "The worst place he could be, if something's really wrong." He looked across at the boy. the trail will get somebody to listen to him! There was nothing singular about the boy's appearance. He was thin, grey monitor-helmet concealed a shock of sandy hair. He sat with a mute appeal in his large grey eyes as Lessing flipped the reader-switch and blinked in alarm at the wildly thrashing pattern on the tape. The boy was terrorized. He was literally pulsating with fear. Lessing sat back slowly. "Tell me about it, Tommy," he said gently. "I don't want to go back to the Farm," said the boy. "Why?" "I just don't. I hate it there." "Are you frightened?" The boy bit his lip and nodded slowly. "Then what?" Again the mute appeal in the boy's eyes. He groped for words, and none came. Finally he said, "If I could only take this off—" He fingered the grey plastic helmet. "You think that Lessing shook his head. "I don't think so, Tommy. You know what the monitor is for, don't you?" "It stops things from going out." "That's right. And it stops things from going in. It's an insulator. You need it badly. It would hurt you a great deal if you took it off, away from the Farm." The boy fought back tears. "But I don't want to go back there—" The fear-pattern was alive again on the tape. "I don't feel good there. I never want to go back." "Well, we'll see. You can stay here for a while." Lessing nodded at much of that up there." "I know, I know." Lessing chewed his lip. "I don't like it. We'd better set up a battery on him and try to spot the trouble. And I'm afraid "Get a pad, get a pencil! We've got work to do. And when we finish, I with unimaginable potential if it could only be unlocked, they had plunged eagerly into the search, and found themselves in a maddening bramble bush of contradictions and chaos. Nothing worked, and more they struggled, the thicker and more impenetrable the bramble bush became— through the afternoon sun. "I just finished the prelims. He's not cooperating." Lessing ground his teeth. "I should be running him now instead of Somewhere along the line as a child grows up, something happens. We don't know what. We do know that the child's psi-potential gradually withdraws deeper and deeper into his mind, burying itself farther and farther out of reach, just the way a tadpole's tail is absorbed deeper and deeper into the growing frog until there just isn't any tail any underground? What buries it so deeply that adult human beings can't get at it any more?" hard grey plastic material, with a network of wiring buried in the substance, connected to a simple pocket-sized power source. "The major problem," Lessing said, "has been to shield the children in a large room. "They're perfectly insulated from us," said Lessing. "A variety of place them together—they drew each other like magnets. One of our workers spent two weeks trying to find out why the instruments weren't jaw. "You think that it's adult psi-contact that drives the child's potential underground—that somehow adult contact acts like a damper, a sort of colossal candle-snuffer." "That's what I think," said Lessing. "How do you know those children didn't make you take off your monitor?" Lessing blinked. "Why should they?" "Maybe they enjoy the crash when the blocks fall down." Lessing and Dorffman rode back to the Hoffman Center in grim silence. At first Lessing pretended to work finally he snapped off the tape cut it off under him. Well, that's his worry, not yours." Dorffman's face was intense. "Scientifically, you're on unshakeable ground. Every grounds aren't right at all, in this case." Dorffman snorted. "Surely there's nothing wrong with theorizing—" "He wasn't objecting to the theory. He's afraid of what happens after the theory." "So it seems. But why?" "He seems to, you mean. And therefore, anything he says about it ." "But why shouldn't he?" "Because a man can't fight for his life and reputation and still keep his objectivity," said Lessing. "And what if he just happens to be helplessly. "He's sick, Doctor. He's sicker than we ever imagined." "What happened?" "Nothing exactly—happened. I don't quite know how to describe it." came in, but there was no flicker of recognition or pleasure on his pale face. The monitor helmet was still on his head. He just sat there, gripping a toy fire engine tightly in his hands. "Tommy!" Lessing reached out for the toy. The boy drew back in terror, clutching it to his chest. "Go away," he choked. "Go away, go away—" When Lessing persisted the boy bent over swiftly and bit him hard on the hand. Tommy's eyes shifted haltingly to Lessing's face. He nodded. "Go away." "Why are you afraid, Tommy?" "I hurt. My head hurts. I hurt all over. Go away." "Why do you hurt?" "I—can't get it—off," the boy said. The monitor , Lessing thought suddenly. Something had suddenly gone horribly wrong—could the boy really be sensing the source of the trouble? Lessing felt a cold knot gather in the pit of his stomach. He had felt it in his own mind, bursting from the child. Like a violent physical blow, the hate and fear and suspicion and cruelty buried and repressed in the adult mind, crushing suddenly into the raw receptors of the child's mind like a smothering fog—it was a fearful thing. A healthy youngster could survive it, even though the scar remained. But And yet an animal instinctively seeks its own protection . With trembling fingers Lessing reached out and opened the baffle-snap on the monitor. "Take it off, Tommy," he whispered. The boy blinked in amazement, and pulled the grey helmet from his head. Lessing felt the familiar prickly feeling run down his scalp as the boy stared at him. He could feel deep in his own mind the cold chill of terror radiating from the boy. Then, suddenly, it began to fade. A sense of warmth—peace and security and comfort—swept in as the fear faded from the boy's face. The fire engine clattered to the floor. Dorffman stared at it angrily. "It's obviously wrong," he grated. "It doesn't fit. Dave, it doesn't agree with anything "Of course," said Lessing. "According to the theory. The theory says that adult psi-contact is deadly to the growing child. It smothers
