"Doctor," said Dickson angrily, "don't be so blasted optimistic!" It seemed that there were to be no helpful ideas from either of them, and Wallis knew suddenly that it had been a mistake to stop and talk like this, that anything which gave them time to think too deeply about their predicament was a mistake. As the superior officer his display of indecision had not helped things, either. "We have seven more faucets and a practically unlimited supply of acetylene," he said firmly. "We must keep trying." Sometime later -- the doctor estimated it at between twenty and thirty hours, but Dickson, who had had nothing much to occupy him in his litter except holding torches and occasionally talking to Jenny, insisted that it was more like three days -- they had to stop trying through sheer fatigue. Despite recent practice each installation had begun to take more time. Radford fumbled his job with the plugs and staggered around the place as if he were half-drunk, and Wallis, through sheer carelessness, neglected to cover his face with the sacking mask and cowl, the result being a scalded forehead. It wasn't a very serious injury, but the cold made it sting. Back in the sick bay they found the two girls asleep and Dickson wide awake, his teeth clenched tightly, sweating and staring into the darkness above him. He did not look at them or reply when they spoke. Radford shook two tablets out of a bottle, hesitated, then made it four. He said, "You need to go to sleep, Mr. Dickson." To Wallis he said, "One good thing about all this is that we've been working so hard that we are going to go to sleep warm for a change." But Wallis did not go to sleep at once or, at first, completely. They had closed all taps and disconnected all the acetylene tanks before returning to the sick bay, but there was still an awful lot of bubbling and gurgling going on all over the ship. Wallis tried to tell himself that this was a good sign, but then he would contrast the total air space within the tanks with the relatively tiny amount by which they hoped to increase it and he would wonder if it was enough. He would argue then that the tanker had been drifting close to the surface for more than a week and if it was sinking only now, it must be sinking very slowly and that surely a minute increase in over-all buoyancy would tip the balance. But he did not know for certain, and while his mind argued wearily to itself it began to drift more and more frequently into sleep -- a sleep composed of a series of brief, terrifying nightmares in which his fear became reality and where the bubbling and gurgling noises became the sounds of their hull breaking up and a solid mass of water crashed down on them and they tore at the metal walls around them and at each other with their bare hands and screamed and screamed. . . . Eventually his body's weariness would not let him wake himself from these nightmares and somewhere along the way they changed. Wallis dreamed that he was on the bridge of a destroyer somewhere in the Med, to judge by the weather. It was a very pleasant dream, sheer wish-fulfillment. The sky was blue and cloudless, the sea calm with a slight swell, the sun was hot even through his whites, and a patch of sunburn on his forehead itched slightly just to remind him that this wasn't Heaven. Wallis would have been content to stay in that dream forever, but for some reason it began to change horribly, and fade. The sky darkened suddenly, in patches, as if it were a jigsaw puzzle and somebody was taking pieces away. It was much too cold, he realized, to be wearing tropical whites. And all at once the rail of the bridge felt like coarse sacking and the salt tang of the wind became a clammy, almost unbreathable poison which stank of sweat. But the dream did not fade completely. His forehead still itched, and below him the deck moved gently with the action of the waves. VIII In the Unthan flagship the problem, after twenty days of constant study and twice-daily discussions, seemed no nearer solution. Now it was the first discussion period of the twenty-first day and the engineer had just asked permission to speak. "Since two coolings will cause such mental degeneration as to make it impossible for us to operate the ship," the engineer said, "my suggestion is that we do not risk putting ourselves into Long Sleep until the process has been made safe." It was normal for their problem to be restated many times -- too many times -- during the course of these discussions, but his idea was so glaringly obvious that it must simply be a preface to a more important suggestion. And there was something about the engineer's manner, a peculiar air of tension which was foreign to him, which made Deslann listen carefully to every word. I have been wondering," the engineer went on, "if it is possible to correct the malfunction in the Long Sleep equipment or, alternatively, evolve a form of treatment or medication which would negate the equipment's effect on our minds. I realize that this would necessitate the use of an experimental, uh, subject of our species and that this subject might expect to sustain mental or physical injury or perhaps even death. At the same time the reputation and ability of Healer Hellahar, who is a specialist in this particular field, is such that I feel confident that if any harm befell me it would be necessary to the research and therefore unavoidable." There was a highly uncomfortable silence when the engineer finished speaking, and Deslann wondered why it was that in this sophisticated and perhaps degenerate age an act of bravery could give rise to as much embarrassment as it did respect. "Your confidence in me is flattering and perhaps misplaced," the healer said awkwardly when the silence had begun to drag. "We do not have the resources aboard ship to conduct such research, nor have I, in my opinion, the ability." "In any case," Gerrol said in a tone aimed at further dispelling the general embarrassment, "we could not spare you. Every single member of the crew will be required to guide in the main body of the fleet and to land this ship -- " "Then why not simply cool ourselves now," one of the computer team joined in, "and set the warm-up time so that we waken, say, a year before the calculated arrival date, putting everything on automatic. That way we would -- " "Get hopelessly lost," Gerrol finished for him. He went on, "We have insufficient reaction mass for large-scale maneuvering should we arrive wide of the target system. Our reserves are enough only for periodic and minor course corrections." Somewhere in the depths of Deslann's mind an idea stirred, stretched, then went back to sleep again. Perhaps the idea would be a useless one, but the captain thought that he should drag it out into the light and look at it just to make sure. Meanwhile the conversation was rolling on, drifting inexorably away from the subject which had almost given him an idea. He had to get them back onto the subject, but he didn't know which subject it was. "Let's go back a little, Gerrol," Deslann said quickly. "You said that everyone would be needed to land the ship and guide in the fleet. But that is not strictly true. You could do without one of the captains." Abruptly, he stopped. The answer was staring him in the face. And from the other side of the control room Hellahar said softly, "You could do without the healer, too, Gerrol. The captain might need a little help." Deslann knew then that Hellahar had seen the answer also, that the exchange between Gerrol and the engineer had given him the same idea and started his mind on the same train of thought as that followed by the captain. They stared intently at each other while Gerrol registered disapproval at his mentioning the other captain, and the rest of the crew talked and pretended the lapse had never occurred. Deslann had often felt impatience with the weird ideas and activities of the Board of Psychology, but one of their members would have been very useful to him just now. And in the years to come. When he had dismissed the crew with the exception of Hellahar, Deslann decided to test the healer's thinking. The truth was that his pride was a little hurt because Hellahar had found the answer as quickly as he himself had seen it, and while he realized this was sheer pettiness he couldn't help himself. And besides, the test might show that the healer had arrived at an entirely different, and perhaps easier, solution to their problem. Deslann said, "Since this is the flagship, the crew is the best available. Veritable geniuses of astrogators, engineers, computers, and communicators. Not to mention healers and captains, of course. But they, and we, are going to have to organize this highly specialized knowledge and break it down into easily digestible pieces. It will be a long time before we are able to cool them." "That aspect does not worry me," Hellahar replied. "They will realize the importance of what they have to do. The thing which concerns me is what we will do after they have been finally cooled. Do we pick for physical fitness, or heredity, or a combination of the two?" As he talked on there could be no doubt in Deslann's mind that Hellahar had arrived independently at the same answer. Briefly, it called for the existing crew with the exception of Hellahar and himself taking the Long Sleep once only, which would mean that the mental effects would be negligible, and being warmed shortly before the target system was reached. Before the cooling, however, they would have to prepare a written and taped record of their training, duties, and knowledge, this data to be broken down and simplified so that the basics would be within the mental grasp of a child. The children and the children's children, who in the generations to come would stand watch in the flagship and keep the great fleet together and on course, would be the responsibility of Hellahar, the captain, and two unfortunate females whose identities were as yet unknown. Even though the identities of the two were not known, Hellahar was already outlining their personalities by the simple process of eliminating traits which in his opinion were dangerous or otherwise undesirable. Not only had Hellahar got the idea, he was -- perhaps because of his specialty -- way ahead of the captain in some respects. Simply picking them at random was out for several reasons, Hellahar said. The choice might be physically or mentally unsuitable. Or if capable of withstanding the considerable shock of being told of the situation and her position in it, the female in question might already be mated and emotionally tied to another Long Sleeper and this would be a psychological barrier too difficult to overcome. Even as it was, warming two females and requesting that they mate with them because the safety of the fleet and the continuance of the race demanded it was not going to be easy. It was very rare to find a female whose thought processes were not colored and to some extent guided by emotional considerations, and they would be unlikely to find two of them who would be willing to accept logical argument as a form of courtship. . . . ". . . Fortunately for us," the healer went on, "there is a medical profile of each Long Sleeper attached to their tanks, and a great deal of psychological data can be gathered from a purely medical case history -- especially when the history gives endocrinological details and an outline of heredity factors. These data give, however, only a general idea of the personalities concerned, which is going to make our final choice a very uncertain business." As he had been speaking Hellahar's initial excitement had dwindled until now he sounded deadly serious, even afraid. "First," he continued grimly, "they will have to be in good physical condition. There must be no history of hereditary diseases. They must be psychologically stable, intelligent, and adaptable. At the same time there must be the widest possible difference in their generic background, because from the third generation on there will be the problem of inbreeding to consider -- " "Where," Deslann broke in quietly, "does er, uh, beauty place on this list of yours, Healer?" Hellahar stammered, fell silent, and gave the captain a long, searching look. Then he said, "With intelligence and stability and good health on the list, the other goes without saying. A physically efficient person is normally, uh, well-constructed -- it's a simple matter of good design. And it could be argued that a beautiful female is much more likely to be psychologically stable than an ugly one, so that we are forced to choose the former type. "Also," he went on, "since females are more susceptible to emotional rather than logical arguments, and since for the best results the emotion in question must be a two-way affair, in my opinion it is vital that we choose the sort of person we can feel emotional about. "There are many reasons," Hellahar concluded seriously, "why we should pick the best-looking ones." "I'm glad," said Deslann, just as seriously. They both laughed then, loudly and long and at the same time a little self-consciously because they both knew there was nothing at all to laugh at in the situation. They were two children laughing in the dark to show they weren't afraid of the Big Black Gobbler. It was a most uncomfortable, unsatisfying laugh, and it was the last they were going to have for a very long time. For there was nothing in the least amusing about Deslann's explanation of his idea to the rest of the crew, or the more detailed planning and subsequent orders which followed it. There was nothing funny about the responsibility he bore -- a little matter of the continued survival or the extinction of his whole race -- or about the many second thoughts he had. "Why can't we simply warm two couples?" he said to Hellahar some weeks later during one of his periods of self-doubt. "That would relieve us of the initial problem with the females." "Wouldn't work," replied the healer, respectfully but definitely. "We must teach the children, subject them to training and disciplines which will be harsh at times. We could not do that without interference if the children were not our own. Besides, there is still a lot to do before the problem of how best to woo our future mates comes up. . . ."
