his wide, thin body, which constituted the knot at the middle. His neck was flat, too, arching out in another loop. Of all his features, only his head had appreciable thickness and it was crowned with a dozen long though narrower ribbons. Taphetta rattled the head fronds together in a surprisingly good imitation of speech. "Yes, I've heard the legend." "It's more than a legend," said Sam Halden, biologist. The reaction was not unexpected—non-humans tended to dismiss the data as convenient speculation and nothing more. "There are at least a hundred kinds of with a minimum of ten others ! That's more than a legend—one hell of a lot more!" "It is impressive," admitted Taphetta. "But I find it mildly feel that attraction to her? "Try Emmer," he suggested tiredly. "He'll find you irresistible, and "Is he?" She smiled enigmatically. "Maybe, in a biological sense. Too "That's because you're unique," said Halden. "Outside of your own that's true of all other creatures, intelligent or not, with the sole species." "Emmer, a Neanderthal type and our archeologist, is around the higher, she was as cruel to herself as she was to him. And yet he wanted her. "I do think I love you," she said. "And if love's enough, I may marry The racial disparity was great and she had provoked him, but it was not completely her fault. Besides.... Besides what? She had a beautiful body that could bear superior children—and they might be his. unbroken line of evolution that could be traced back a billion years." "You're thinking of Earth," said Halden. "Humans require a certain kind actually a manlike creature there. Naturally our early evolutionists stretched their theories to cover the facts they had. only the human race." about himself." It was easy to understand the attitude. Man was the most numerous though not always the most advanced—Ribboneers had a civilization as others—and humans were more than a little feared. If they ever got together—but they hadn't except in agreement as to their common origin. "As accurate as it can be with a million-plus body problem." "To the best of our knowledge," said Kelburn. "And whereas there are humans who are relatively near and not fertile, they can always mate !" "The adjacency mating principle. I've never seen it demonstrated," satisfies the calculations?" The evidence is sometimes contradictory, but we believe we've got the time right." Halden flushed the sarcasm wasn't necessary. It was true that Kelburn was the most advanced human type present, but while there were differences, biological and in the scale of intelligence, it wasn't as great as once was thought. Anyway, non-humans weren't trained in the fine distinctions that men made among themselves. And, higher or lower, he was as good a biologist as the other was a mathematician. And there was the matter of training respect. The Ribboneer shifted his attention. "Aside from the sudden illness of ability." Taphetta crinkled politely at the reference to his skill. "I had other profits from any discoveries we may make." "I'm complimented that you like our contract so well," said Taphetta, you all day—it's micro-printing. However, you needn't be afraid that I'm defrauding you. It's honored everywhere we go and we go nearly everywhere in this sector—places men have never been." There was no choice if they wanted him, and they did. Besides, the an equal lack of grace. He seemed to have difficulty in taking his eyes off Meredith, though, since he was a notch or so above her in the been inexplicably slow in developing and he wasn't completely aware of his place in the human hierarchy. long and beautiful a woman's legs could be. Her people had never given much thought to physical modesty and, with legs like that, it was easy to see why. less complex than Man. It was a paradox that some biologically higher humans hadn't developed as much as lower races and actually weren't were folded neatly around the arms and his head rested comfortably on the seat. The head ribbons, which were his hands and voice, were never quite still. it detects and avoids, even electronic traps." "Then you believe it changed mentally as well as physically, that it's "I'd say that, yes. It must be a fairly intelligent creature to be strong enough." "That's what I don't like," said Taphetta, curling. "Let me think it over while I ask questions." He turned to Emmer. "I'm curious about Emmer didn't look like the genius he was—a Neanderthal genius, but nonetheless a real one. In his field, he rated very high. He raised a stubble-flecked cheek from a large thick-fingered paw and ran shaggy hands through shaggier hair. "I can speak with some authority," he rumbled. "I was born on a world with the most extensive relics. As a child, I played in the ruins of their camp." "I don't question your authority," crinkled Taphetta. "To me, all humans—late or early and male or female—look remarkably alike. If you structures and that's how we can guess at their size. The doorways were forty feet high." "Very large," agreed Taphetta. It was difficult to tell whether he was "Who knows? Their mental processes were certainly far different from they visited so many of that type, yet different from it because they never stayed. They were pretty special people themselves, big and long-lived, and maybe they couldn't survive on any planet they found. Perhaps they had ways of determining there wasn't the kind of planet "We helped them," said Emmer. And they had, no matter who or what they were, biologically late or early, in the depths of the bronze age or the threshold of atomic—because they were human. That was sometimes a frightening thing for non-humans, that the race stuck together. They weren't actually aggressive, but their total number was great and they held themselves aloof. The unknown ancestor again. Who else had such an origin and, it was tacitly assumed, such a destiny? institutions that are backing you did so purely out of intellectual curiosity." "Cultural discoveries," rumbled Emmer. "How did our ancestors live? contract and the one we offered you? Our terms are more liberal." "To the individual, they are, but it won't matter if you discover as a minimum, but when you do use it, be vague. Don't try to imitate them that the bodies aren't flesh." exactly like the pests? And if not, will the pests be fooled?" marrying you." "Primitive," he said, alternately frozen and thawed, though he knew that, in relation to her, he was not advanced. "It's almost a curse, isn't it?" She laughed and took the curse away by Here we go again, he thought drearily, sliding his arm around her. To her, I'm merely a passionate savage. wasn't tall, only by Terran standards. Her legs were disproportionately long and well shaped and her face was somewhat bland and featureless, "Would it be wrong?" he asked. "I'm as intelligent as you. We wouldn't have subhuman monsters." "It would be a step up—for you." Under her calm, there was tension. The conflict was not new nor confined to them. In one form or another, it governed personal relations between races that were united against non-humans, but held sharp distinctions themselves. "I haven't asked you to marry me," he said bluntly. "Because you're afraid I'd refuse." It was true "Kelburn." It didn't sound like a name, the way she said it. "I don't like him and he wouldn't marry me." "He wouldn't, but he'd give you children if you were humble enough. There's a fifty per cent chance you might conceive."
