Niobe—a perfect name for this wet little world. The Bureau of Extraterrestrial Exploration couldn't have picked a better, but the funny thing about it was that they hadn't picked it in the first place. was irresistible temptation to Niobe's bloodsucking insects. Many of He looked at Kron squatting beside the trail and envied him. It was too bad that Earthmen weren't as naturally repellent to insects as the dominant native life. Like all Niobians, the native guide wore no Kron, Lanceford reflected, was a good example of the manner in which Kron resembled humanity—but there were differences. Squatting, the peculiar shape of Kron's torso and the odd flexibility things they apparently enjoyed. Tastes differed—enormously so between Earthmen and Niobians. There was no doubt that the native was intelligent, yet he, like the rest of his race, was a technological moron. It was strange that a race which had a well-developed philosophy and an amazing comprehension of semantics could be so backward in mechanics. Even the simpler of the BEE's mechanisms left the natives confused. It was possible that they could learn about machinery, but Lanceford was certain that it would and as he did so, Kron stood up, rising to his five-foot height with a curious flexible grace. Standing, he looked something like a Lanceford looked at Kron inquiringly. "You have a place in mind where airless rooms filled with natives. He sighed wearily as he followed Kron along the dim path through the his eyes to become accustomed to the gloom within, but his nose told him even before his eyes that the house was occupied. The natives, he thought wryly, must be born with no sense of smell, otherwise they'd perish from sheer propinquity. One could never honestly say that familiarity with the odor of a Niobian bred contempt—nausea was the above the flames. Kron was already in the ring, talking earnestly to were almost painfully polite. Although Earthmen were still enough of a curiosity to draw attention, one searching look was all their customs allowed. Thereafter, they minded their own business. In some ways, Lanceford reflected, native customs had undeniable merit. Presently Kron rose from his place beside the fire and pointed out two Weariness flowed over him. He awoke to the gentle pressure of Kron's hand squeezing his own. "The system could handle the unsavory mess, but his taste buds shrank from the forthcoming assault. What the natives classed as a delicate and elusive flavor was sheer torture to an Earthman. Possibly there was some connection between their inefficient olfactory apparatus and their odd ideas of flavor, but whatever the physical explanation might be, it didn't affect the fact that eating native considered worthy of the name unless a generous helping of vorkum started it off. An entree like that could ruin the most rugged human appetite, but Kron offered. The Niobian never seemed to learn. At every meal they had eaten during their past month of travel on Niobe, Kron had persistently offered him samples of the mess. With equal persistence, he had refused. After all, there were limits. delicacy of vorkum. But it was a known fact that the ways of Earthmen were strange and unaccountable. a week ago had sensitized him. He was developing an anaphylactic reaction—a severe one, judging from the swelling. That was the trouble with exploration one occasionally forgot that a world was alien. Occasionally danger tended to recede into a background He sighed and lay back. There wasn't anything more to do now. All he could do was wait and see if the anti-allergen worked. The Bureau of Extraterrestrial Exploration had discovered Niobe barely three years ago, yet already the planet was famous not only for its peculiar climate, but also for the number of men who had died upon its watery surface. Knowledge of this planet was bought with life, grim payment to decrease the lag between discovery and the day men could live and work on Niobe without having to hide beneath domes or behind It was the source of a complex of alkaloids known as gerontin, and gerontin had the property of tripling or quadrupling the normal life right conditions existed in very few places in the explored galaxy. Despite the fact that most life is based on carbon, oxygen and water, there is still very little free water in the Galaxy. Most planets of blank check and spurred on by a government which, in turn, was being spurred on by the people who composed it. The exploration of Niobe Seemed rather silly—a Class VII civilization using techniques that were old during the Dark Ages before the Atomic Revolution, sending foot parties to explore a world in the chance that they might discover something that the search mechs missed—anything that would shorten the from Kron. Despite his intelligence, the native could no more assemble pad. But it was difficult to write. Painful, too. Better get Kron over "Kron! Come here! I need you!" Kron looked down compassionately at the swollen features of the Earthman. He had seen the kef effect before, among the young of his reacted like his own people. had denied his help for weeks, and Niobians simply didn't disregard another's wishes. Kron scowled, the action lending a ferocious cast to his doglike face. Tolerance was a custom hallowed by ages of practice. Kron buried his long-snouted head in his hands, a gesture that held in The human was apparently resolved to die. He had told Kron his last wishes, which didn't include a request for help, but merely to get his pack back to the others in their glass dome. It was astonishing that such an obviously intelligent species should have so little flexibility. They didn't understand the first principles of adaptation. Always and forever, they held to their own ways, trying with insensate stubbornness to mold nature to their will—and when nature overcome their artificial defenses, they died, stubborn, unregenerate, inflexible to the end. They were odd, these humans—odd and a little Kron nodded, but then belatedly realized that the human was muttering dying murmurings, something that might explain their reasons for being here and their strange driving haste that cared nothing for life. "You don't want to die!" Kron exploded. that Kron was nearby. This might well destroy the Imperturbable "Do you mind if I help you?" Kron asked diffidently. "I think I can Kron's eyes were brilliant. He hummed softly under his breath, the endure the night rain than be present when the alien died. Kron was thankful that they were gone, for what he was about to do would shock Lanceford was dimly conscious of Kron prying his swollen jaws apart Kron had given him apparently had some anesthetic properties. He felt dimly grateful, even though the primitive native nostrum would probably do no good other than to ease the pain. He couldn't see Kron—the muscles that moved his eyes were as paralyzed He was aware of the incredible complexity and richness of Kron's thoughts, of oddly sardonic laughter, of pity and regret that such a little thing as understanding should cause death and suffering through its lack, of bewildered admiration for the grim persistence of the alien Earthmen, mixed with a wondering curiosity about what kept them here—what the true reasons were for their death-defying persistence and stubbornness—of an ironic native paraphrase for the Terran saying, "Every man to his own taste," and a profound speculation upon what fruits might occur from true understanding between his own race and the explorer's isolated mind, a flash that passed almost as soon as it had come, as though an invisible door had closed upon it. But one thing in that briefly shocking contact stood out with great in Kron's mind that he was thinking not only for himself but for
