up in neat rows like pins in a paper. Maybe we were so blind we missed the path altogether." "But the book is due! The Conference speech—" "I think we'll make some changes in the book," Lessing said slowly. "It'll be costly—but it might even be fun. It's a pretty dry, logical presentation of ideas, as it stands. Very austere and authoritarian. Dr. David Lessing found Jack Dorffman and the boy waiting in his office 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 appeal in his large grey eyes as Lessing flipped the reader-switch and blinked in alarm at the wildly thrashing pattern on the tape. "Of me? Of Dr. Dorffman?" "No. Oh, no!" "Then what?" "You think that would make you feel better?" "It would, I know it would." 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." "Well, we'll see. You can stay here for a while." Lessing nodded at "I'm afraid so. We thought it was just a temporary pattern—we see so 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 deal with this morning—the one who's threatening to upset the whole Conference next month with some crazy theories he's been playing with. I'll probably have to take him out to the Farm to shut him up." Lessing ran a hand through sparse grey hair. "See what you can do for the boy trouble I think he's in, we don't dare risk a chance of Adult Contact now. We could end up with a dead boy on our hands." Two letters were waiting on Lessing's desk that morning. The first was from Roberts Bros., announcing another shift of deadline on the book, and demanding the galley proofs two weeks earlier than scheduled. Lessing groaned. As director of psionic research at the Hoffman Medical Center, he had long since learned how administrative detail could suck up daytime hours. He knew that his real work was at the Farm—yet he hadn't even been to the Farm in over six weeks. And now, as the book approached publication date, Lessing wondered if he would ever really get back to work again. The other letter cheered him a bit more. It bore the letterhead of the International Psionics Conference: Dear Dr. Lessing: In recognition of your position as an authority on human Psionic behavior patterns, we would be gratified to schedule you as principle speaker at the Conference in Chicago on October 12th. A few remarks in discussion of your forthcoming book would be entirely in order— They were waiting for it, then! He ran the galley proofs into the title—concise, commanding, yet modest. They would read it, all right. And they would find it a light shining brightly in the darkness, a guide to the men who were floundering in the jungle of a strange and Lessing a bony hand, then flung himself into a chair as he stared about the office in awe. "I'm really overwhelmed," he said after a moment. "Within the Master in the trembling flesh!" Lessing frowned. "Dr. Melrose, I don't quite understand—" "Oh, it's just that I'm impressed," the young man said airily. "Of course, I've seen old dried-up Authorities before—but never before "If you've come here to be insulting," Lessing said coldly, "you're just wasting time." He reached for the intercom switch. "because I'm planning to take you apart at the Conference next month unless I like everything I see and hear down here today. And if you don't think I can do it, you're in for quite a dumping." Lessing sat back slowly. "Tell me—just what, exactly, do you want?" "I want to hear this fairy tale you're about to publish in the name of 'Theory'," Melrose said. "I want to see this famous Farm of yours up in true." "If the papers you've already published are a preview, we think it's Lessing slammed his fist down on the desk angrily. "Have you got the day to take a trip?" Lessing shouted for his girl. "Get Dorffman up here. We're going to the 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 Melrose grinned. "I've heard you have quite a place up here." "It's—unconventional, at any rate," Lessing snapped. Lessing glared at him. "When we began studying this psi-potential, we long, low building. "All right, young man—come along," said Lessing. "I think we can show you our answer." "Which may not be very far." Jack Dorffman burst in: "What Dr. Lessing is saying is that they seem effective for our purposes." "But you don't know why," added Melrose. Lessing smiled. "This is an isolated phenomenon—it doesn't hold for any other three children on the Farm. Nor did we make any effort to Moments later Lessing was back in the observation room, leaving the Lessing blinked. "Why should they?" "Maybe they enjoy the crash when the blocks fall down." Melrose paced down the narrow room. "This is very good," he said suddenly, his voice earnest. "You have fine facilities here, good workers. And in spite of my flippancy, Dr. Lessing, I have never imagined for a moment that you were not an acute observer and a professionally, discredit anything we did, cut us off cold." The tall man turned on him fiercely. "Are you blind, man? Can't you see what danger you're in? If you publish your book now, you will become an Authority in a field where the most devastating thing that could possibly happen would be— At first Lessing pretended to work finally he snapped off the tape great researcher has people like Melrose sniping at him. You just have to throw them off and keep going." Lessing shook his head. "Maybe. But this field of work is different 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 carries more weight than what anybody else says. Other workers follow his lead. He developes ideas, formulates theories—and then defends them for all he's worth ." "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 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. , 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 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 drying up there on the Farm, until the distortion was threatening the balance of his mind. Then he made an adult contact, and we saw how he bloomed." Lessing sank down to his desk wearily. "What are we going to "Didn't you see his face ?" Lessing burst out. "Didn't you see how he acted
