to subdue a defenseless world—only to meet on was well above the average in height—but his body was thick and powerfully muscled. His skull was well-shaped and large his features The Orthan entered the narrow strip of trees and crossed to the wait for an Earthman or an Earthwoman to pass. His task now was to bring a native, intact if possible, back to the carefully buried space cruiser where his two fellows and himself would drain the creature's mentality of all its knowledge. In this way they could learn whether a planet was suited for colonization by later swarms of Orthans. time. The mighty muscles of the Orthan sent him hurtling across the of his subconscious. Yet he had Earthman to the metal deck-plates. "It is a male of the species that wears he might be Thig." "Thig will be this creature!" announced Torp. "With a psychic relay we will transfer the Earthman's memories and meager store of knowledge to the brain of Thig! He can then go out and scout this world without arousing suspicion. While he is gone, I will take Kam and explore the two inner planets." these clumsy sheathing upon his body. On Ortha we do not hamper the use you disguise yourself as an Earthman." "For the good of the Horde," Thig intoned almost piously as he lifted Terry's body and headed for the laboratory. Service for the Horde was all that the men of Ortha knew. Carefully cultured and brought to life in the laboratories of their Horde, they knew neither father nor mother. Affection and love were entirely lacking in their early training and later life. They were trained antlike from childhood that only the growth and power of the Horde robots of flesh and bone for the Horde. The Horde was their religion, their love-life, their everything! So it was that the bodies of the Earthman and the Orthan were strapped one another by the intricacies of the psychic relay, put upon their heads. completely. Twice, with subtle drugs they restored pseudo-life to his "There is nothing more to learn," he informed his impassive comrades. "Now, let us get on with the plastic surgery that is required. My new body must return to its barbaric household before undue attention is aroused. And when I return I will take along some of the gleaming baubles we found on the red planet—these people value them highly." An hour later, his scars and altered cartilage already healed and memories of this particular section of Long Island. Here was the place where Jake and Ted had helped him dig for the buried treasure that old 'Notch-ear' Beggs had told them so exactly about. Remembrance of acquired memories labeled as pleasure, sent a warm glow upward from around his heart. Then he saw the slender red-haired shape of a woman, the mate of the primitive impulses of barbarism so he was incapable of understanding the emotions that swept through his acquired memory. he acquired the knowledge of Terry that he found himself unconsciously adopting the thinking and mannerism of the other. All the better this way, he realized—more natural. chaos of his cool Orthan brain. including Ortha, was so well-favored and rich. An expeditionary force to wipe the grotesque civilizations of Earth out of existence would, of course, be necessary before the first units of new Hordes could be landed. And there Thig balked. Why must they destroy these people, Hordes? Thig tried to tell himself that it was the transmitted thoughts of the dead Earthman that made him feel so, but he was not too sure. For three months he had lived with people who loved, hated, wept and sacrificed for reasons that he had never known existed. He had learned the heady glory of thinking for himself and making his own decisions. He had experienced the primitive joy of matching his wits and tongue against The Orthan had come to question the sole devotion of the individual to the Horde to the exclusion of all other interests. What, he wondered, would one new world—or a hundred—populated by the Hordes add to the progress of humanity? For a hundred thousand years the Orthan mechanical hives. sapping the life from his own brain. He knew that the story would never So far had Thig the emotionless, robot-being from Ortha drifted from "I will recommend the conquest of this planet, 72-P-3 at once and the complete destruction of all biped life upon it. The mental aberrations of the barbaric natives might lead to endless complications if they were permitted to exist outside our ordered way of life. I imagine that three circuits of the planet about its primary should prove sufficient for the purposes of complete liquidation." "But why," asked Thig slowly, "could we not disarm all the natives and exile them on one of the less desirable continents, Antarctica for example or Siberia? They are primitive humans even as our race was once a race of primitives. It is not our duty to help to attain our own degree of knowledge and comfort?" race of feeble-witted beasts, such as these Earthmen, stand in the way of a superior race? We want their world, and so we will take it. The Law of the Horde states that all the universe is ours for the taking." There are forces at work upon Earth that we of Ortha have long forgotten." "Check the blood of Thig for disease, Kam," ordered Torp shortly. "His words are highly irrational. Some form of fever perhaps native to this world. While you examine him I will blast off for Ortha." stand between them! The Hordes of Ortha must find some other world, an empty world—this planet was not for them. woman there, helpless and alone, who needs me! The Horde does not need this planet." Kam eyed him coldly and lifted a shining hypodermic syringe from its case. He approached Thig warily, aware that disease often made a maniac of the finest members of the Horde. "No human being is more important than the Horde," he stated baldly. must eliminate for the good of the Horde." the Orthan's vital throat tubes. His fingers and thumb gouged deep into matter. Horror for what he had done—that he had slain one of his own ancestors at times but to that very bit of unconscious atavism he now owed his life. A cool-headed robot of an Orthan would have efficiently used the blaster to destroy any possibility of remaining life in his unconscious body. why he had been left until last. Perhaps Torp wished to take cultures of his blood and tissues to determine whether a disease was responsible for his sudden madness. The cases of fragile instruments were just above his head. Association The deadly attack of Thig his own violent avenging of Kam's death, and now the apparent return of the man he had killed come to life had all served to jolt his rigidly trained brain from its accustomed groove. The shock had been too much for the established thought-processes of the Orthan. He had saved a world's civilization from extinction! The thought Planet 72-P-3 unfit for colonization. Some pernicious disease that strikes at the brain centers and causes violent insanity is existent planet Ortha.

The sensation of free flight against his new body was strangely exhilerating and heady. It was the newest of the emotions he had experienced on Earth since that day, so many months before, when he had felt the warmness of Ellen's lips tight against his. regret in his mind that he was not returning to the planet of his first below. And there was a sickness within him when he fully realized that, despite his acquired memory and traits, he was an alien from outer space. He fingered the tiny scars that had completely obliterated the slight
