Close To Critical Part 12

"Who cares about just tomorrow? How you human beings ever achieved even the civilization you have is a mystery to me. Intelligent people plan ahead." "Intelligent people don't usually jump to conclusions, either," snapped the girl, in the first display of temper she had shown since the accident. "I'm not worried beyond tomorrow, because by the end of that day we'll be away from here. Please tell Mr. Sakiiro to have the shuttle ready to meet us." She turned her back and walked-stalked, rather-out of the field of view; and Aminadabarlee was too startled even to resent the discourtesy.

XII. CAPITULATION; OPERATION; ELEVATION.

EASY was awake again by the time Nick reached the bathyscaphe. He had had no trouble finding it; the glow from its lights was quite visible from the coast. The wind was blowing straight toward the light, but Nick and his friends knew nothing of the volcano at the tune and didn't have to worry about whether they were heading for the right light. They came ash.o.r.e, shouldered the raft, and headed for their beacon.

f.a.gin and the other four pupils had arrived before them; travel on foot was a good deal faster, even for the robot, than by the decidedly clumsy raft. Swift seemed to be in a very tolerant mood. He didn't actually greet the newcomers effusively, but he was talkative enough. He took for granted that they were his people-people who had gone a trifle astray, and didn't always know just how to behave, but who might be expected to grow up properly if given time. As long as they treated him as chief, it seemed likely that there would be no trouble.

Within a few minutes of the arrival of John, Nancy, Oliver, Dorothy, and the robot, he had demanded to be shown how to make a fire. Easy, with her two-second advantage in reaction time, told John to go ahead before Raeker even knew the order had been given. John, knowing that the person hi the bathyscaphe was one of his teacher's race, obeyed without question. He took out 176.

Capitulation; Operation; Elevation 177 his friction gear and had a blaze going in two or three minutes.

Swift then demanded to be shown how to work the device himself; and by the time Nick, Betsy, Jim and Jane arrived with the raft the chief had succeeded in lighting his own fire and was in the highest of spirits.

This was more than could be said for anyone on the Vindemiatrix. Aminadabarlee was more than ever convinced that human beings were an ugly-tempered, uncooperative lot; and just now he had more than the usual reason for his opinion. Every human being in the s.h.i.+p was furious with the Drommian, taking their lead from Easy Rich. A night's sleep had not restored her usual sunny temper; she was indignant at the alien's insults of the evening before, and not only refused to explain to Aminadabarlee her justification for saying she would escape within a Tenebran day, but would say nothing more about it to anyone for fear he would hear. It was a childish reaction, of course; but then, Easy was a child, for all her adult speech and mannerisms. Her father had been asked to persuade her to talk; he had stared at her imaged face in the screen for a moment, but no word was spoken. Something must have pa.s.sed between them, though, for after a moment he turned away and said, "Please have Mr. Sakiiro get the shuttle ready to meet the bathyscaphe. I understand it takes some time to install and adjust outside boosters." He promptly left the room, ignoring the questions hurled at him, and disappeared into his own quarters.

"What do we do?" The question was not in the least rhetorical; the geophysicist who put it was a close friend of the Rich family.

"What he says, I should think," answered another scientist. "Rich seems to be sure the kid knows what she's talking about."

"I know he's sure; but does she? He's her father; she's all the family he's had for ten years, and he's done a 178.

marvelous job of bringing her up, but he sometimes overestimates her. She convinced him, just then, that everything is all right; but I don't-we don't know. What do we do?"

"We do just what he asked," pointed out another. "Even if the kid's wrong, there's no harm hi having the shuttle ready. Why is everything so shaken up?"

"Because we know what will happen to Easy and her father if she's wrong," replied the geophysicist. "If she's been speaking from her own knowledge, fine; but if that ten-legged weasel made her lose her temper and shoot her mouth off so as to justify her actions-" He shook his head grimly. "She believes her own words now, all right, and so does her father. If they're disappointed-well, the kids have stayed alive down there so far because of the self-control of the Rich family." He ended the discussion by cutting in another phone circuit and transmitting Rich's request to the engineers.

Raeker had been eating and, occasionally, sleeping in the observation room; he'd forgotten by now how long he had been there. The robot was rather out of things, but he could still watch. His pupils seemed to have been re- absorbed into Swift's tribe, and were being told what to do alternately by the chief himself and by Easy in the bathyscaphe. n.o.body was asking f.a.gin what to do or how to do it, but in spite of this things were happening almost too fast for Raeker to keep track of them. He knew that Easy had had an argument with Aminadabar-lee, though he wasn't clear as to the details; he had been told about her promise to be off the ground the next day, but had no more idea than anyone else how she expected to do it. He had had his share of Aminadabarlee's temper, for the Drommian had not by any means been silenced by Easy's flare-up, and had spent some time pointing out to Raeker the foolishness of separating his pupils from their own culture, and how much more would have been learned about Tenebra if contact had been made with Capitulation; Operation; Elevation 179 Swift's people in the first place. Raeker had not actually been rude, but his answers had been rendered vague by his preoccupation with events on the ground, and he had thereby managed to offend the lutroid more than ever. He knew it, but couldn't bring himself to worry seriously about the prospect of severed relations between Sol and Dromm.

He knew in a general way what people were doing on the ground, but he couldn't understand all of it, and no one bothered to tell him. It never occurred to Raeker that this might have been at Easy's request; that she might be going to extremes to make sure that nothing like useful information got back to the Vindemiatrix and the being who had angered her so. He could only watch, photograph, record what conversation he could hear, and try to interpret what went on.

The raft was launched, and Nick and Betsey took Swift out on the surface of the pool to a point just out- side one of the bathyscaphe's observation ports. Raeker could see the meeting between Tenebrans and the s.h.i.+p's two occupants^ but could not hear their conversation- Easy was, of course, using the outside speakers, and the robot was too far away to hear these directly. The talk was long, and quite animated, for the gestures of all parties concerned could be seen-the port was large enough to let Raeker see fairly well into the 'scaphe even from the robot's vantage point. He tried to interpret the motions, but had no luck.

Conversation did not end until nearly night; then the raft returned to the sh.o.r.e, and everyone began to pack up. A dozen cave dwellers helped carry the raft, others helped pull the cart. For the first time, Swift paid attention to the robot; he ordered it to come along, using Nick as an interpreter. Raeker agreed briefly; the journey was obviously to escape the sea, which would presumably come at least as far inland tonight as it had before.

"Where will the big s.h.i.+p go tonight?" he asked, more 180.

CLOSE TO CRITICAL.

to secure a demonstration of the cave people's abilities than because the answer made any difference to him. He rather expected Swift would not bother to answer, but t.i.tle chief was in a very good humor- everything had been going just as he wanted it all day. Once the group was under way, he walked beside the robot and talked quite cheerfully. Nick relayed his words, and he described in great detail the country which they were approaching and the point to which he expected the bathyscaphe to be washed. He also explained his reasons for this opinion, and the geophysicists listened, took notes, and watched with motherly care the recorders which were storing the conversation. For the first hour or two of that night there was more general happiness than the region of Altair had experienced for decades. About the only people not sharing in it were Aminadabarlee and Raeker.

Swift stopped his cavalcade after a scant two hours of rather slow travel. Night had fallen, and the rain was starting to do likewise; he set everyone to work gathering firewood, and ordered Nick to place the guard fires for a camp. Nick and his fellows obeyed without argument; Raeker suspected that they were human enough to enjoy the chance to show off their knowledge. Cave dwellers were at each of the fire sites practicing with friction drills, and one by one the piles of fuel began to glow.

For sixteen years, the lighting of the evening fires had been a signal for a forty-eight-hour period of relaxation on the Vindemiatrix, since nothing but rain ever happened at night on Tenebra. Now that was changed; discussion, sometimes verging on argument, went on full tilt. The engineers were busy festooning the outside of the shuttle with hydroferron boosters and their control lines. The diplomats wouldn't have been speaking to each other if they had followed their personal inclinations, but pro- fessional pride kept them outwardly courteous. People who knew them, however, listened to their talk very uneasily, and thought of jammed reactor control rods.

Capitulation; Operation; Elevation 181 A few enthusiasts kept watch through the robot's eyes, partly in the hope that something would happen and partly to keep Raeker company. The biologist refused to leave the observation room; he felt sure that matters were building to some sort of climax, but couldn't guess just what sort. Even during the night this feeling grew worse -particularly at such times as he happened to see or hear one of the diplomats.

Actually, Raeker was suffering badly from a sudden lack of self-confidence; he was wondering how he could possibly teach his students to make the necessary repairs on the bathyscaphe, even if they chose to listen to him. If they wouldn't, or couldn't, he didn't want to see or hear of Rich or Aminadabarlee again; he had convinced himself, quite unjustly, that his own arguments had caused them to pin their faith in him and not undertake any other steps toward a rescue.

In spite of the anxiety which let him sleep only for moments at a time, he managed to get through the night. The departure of the shuttle distracted him for a few minutes-at one point he almost convinced himself that he should go along with it, but common sense prevailed. Several times incidents occurred at the camp, and were pictured on the robot's screen, which would have made him laugh under different circ.u.mstances. The cave dwellers were not at all used to fires yet, and had some odd ideas of their properties, uses, and limitations. Several times Nick or one of the other human-educated natives had to make a rescue as someone ran blithely into the dead-air zone of a boiled-away raindrop to relight a fire.

When they finally realized that a newly destroyed raindrop was like a newly boiled lake in the early morn- ing, some of them took to waiting a long time before venturing near the extinguished fires, so that the fuel cooled too far to let the blaze spring back to Me at the mere touch of a torch. Several of them grew worried about the fuel supply, which the experienced group had p.r.o.nounced sufficient, and kept trying to persuade Swift to organize 182 CLOSE TO CRITICAL.

wood-collecting parties. Raeker could not, of course, understand these requests, but he heard a couple of his own people commenting on them with something like contempt in their voices. This made him feel somewhat better; if his pupils felt that way about the cave dwellers, perhaps they still had some attachment for their teacher.

Morning finally came without any serious incident in camp or at the bathyscaphe; and once the hill on which the camp was located ceased to be an island-it had been surrounded by the usual rainfall, but not by ocean, as far as anyone could tell-the group headed for the spot where the bathyscaphe was expected to be. This meant a walk nearly as long as that of the previous night, since Swift and his people had expected little motion on the part of the stranded machine. Raeker didn't know whether Easy had reported any drifting; he hadn't heard her voice very often during the last forty-eight hours.

Raeker himself wasn't sure how far to believe the predictions of the natives, and wasn't sure how far he wanted to believe them. If they proved right, of course, it would mean a lot to the geophysicists; but it might also mean that Easy had some grounding for her optimism about the day's events. That was good only it it was solid grounding; and Raeker could not for the life of him imagine how the girl expected the machine to be either flown, blown, or carried up to a point where the shuttle could meet it. On the few occasions that he had dozed, his sleep had been troubled by wild nightmares involving volcanoes, floaters, and forms of sea life whose shapes never became quite clear.

There was no question of how the geophysicists felt when the predicted spot was reached and the bathyscaphe found to be absent. They buzzed like a swarm of bees, hurling hypotheses at each other with scarcely time to listen to their neighbors. Aminadabarlee fainted, and const.i.tuted an absorbing first aid problem for several minutes until he revived by himself, none of die men having the Capitulation; Operation; Elevation 183 slightest idea of what to do for him. Fortunately, the s.h.i.+p turned up after a quarter of an hour's search exactly where it had been left the night before, which made things easier on the fathers but left many human beings and quite a few Tenebrites rather at a loss for an explanation. The sea had certainly been there; Easy had reported as much. Apparently its transporting power had been lower than expected. Some of the scientists pointed out that this was obvious; this much farther from its natural bed, the sea would be correspondingly more diluted with water. It satisfied him and some of his friends, but Rae-ker wondered how a slightly greater dilution of something which must already have been pretty pure H2O, as pure water went on Tenebra, could make that much difference. He wondered what excuse Swift was using, but couldn't find out.

Nor could he find, except by guesswork, the nature of the plan that was being executed before the robot's eyes.

Hunting parties-judging from their armament-were sent out in great numbers, each one accompanied by one of f.a.gin's pupils with his axe. The raft made trips to the bathyscaphe, and Swift and several others examined its surface with great care; Easy seemed to be talking to them while this went on, but Raeker and his companions couldn't hear what she said. The natives were greatly interested in the hot area at the top of the vessel, where its refrigerators pumped back overboard the calories they had drawn from the living quarters; they started to climb up the hull, by means of the numerous handholds, to examine this more closely. This act, since the craft was circular in cross section and just barely not floating, started the whole vessel rolling toward the raft; the climbers dropped back hastily. One of them fell into the lake, lost consciousness before he could grasp the paddles thrust down to him, and had to be shoved clumsily into shallow oleum by his fellows lying on the raft above him. This brought the raft itself closer to the robot, and Raeker 184 CLOSE TO CRITICAL.

was able to hear Nick remark to Betsey, "This will save a lot of time. If the teachers inside don't mind, we can roll that thing over here where we can work on it."

"We may do it whether they mind or not, if Swift gets the idea," was the reply. "We'd better ask in English first."

"Right. Let's get back out there." The two slid the raft back into the pool and paddled back toward the stranded vessel. This time Raeker knew what the conversation was about even though he couldn't hear it, and he knew how it canie out-he could see Easy nod her head in a.s.sent. It was several seconds before a frightening thought struck him, and made him call the engineering department.

"Will turning that bathyscaphe over do any harm?" he asked without preamble. "The natives are planning to roll it out of that pool."

The men at the other end exchanged glances, and then shrugged at each other.

"Not as far as I can think at the moment," one of them said. "The s.h.i.+p was designed to fly, and it was a.s.sumed that inverted flight might be necessary. The kids may be b.u.mped around a bit, and anything they've left loose will tumble, but nothing vital should suffer."

"Thank goodness for that," Raeker said feelingly, and turned back to his screens. The raft was on its way back to sh.o.r.e, and Nick was calling something to Swift. Raeker could catch only a word or two, since the native language was being used, but he could tell easily enough what was being discussed. Swift got aboard as soon as the raft reached wading depth, loading it to capacity. Back at the bathyscaphe, he and Betsey seized the handholds on the hull and began carefully to climb, Nick staying on the raft to keep it out of the way. Raeker expected some more accidents, but the climbers showed surprising skill and co- ordination, keeping just above the liquid surface as the s.h.i.+p slowly rocked toward them. It was lucky that the handholds extended all over the hull; Raeker was sure Capitulation; Operation; Elevation 185 they hadn't checked this point before starting their stunt.

A quarter turn brough the hot "exhaust area" into contact with the pool, and set the oleum bubbling furiously- or as close to bubbling as anything could come under Tenebra's atmospheric pressure. There was enough disturbance to attract the attention of the natives on the s.h.i.+p, but not to be visible from sh.o.r.e.

Two full rolls brought her to wading depth, and robbed her of enough buoyancy to make another climber necessary. Three turns brought her right side up at the sh.o.r.e line. A slight complication arose when the climbers dropped off and she started to roll back, and for the first time Raeker was able to make himself heard and listened to; he gave some rapid advice about placing chocks, which Nick heeded. With the hull stable and the children staring out at the robot a few yards away, Raeker thought he might learn what was going on, and he used the machine's speaker.

"h.e.l.lo, Easy. We're finally together."

"h.e.l.lo, Doctor. Yes, your people are here. I thought we'd be able to do without them, but they've been a big help. Are you staying to watch the rest?"

The question startled the biologist, to put it mildly.

"Staying? We're just starting to work. I'll call the engineers and have them listen in while I explain the electrolysis circuits to Nick and the others; they'd be here now, only I didn't expect the s.h.i.+p to be available quite so quickly. We'll find whatever wires are corroded or disconnected, and-" Easy must have started talking before he got that far, but the transmission lag delayed his hearing her interruption.

"I'm sorry, Doctor, but I'd rather not have Nick fooling with the s.h.i.+p's wiring. I don't understand it myself, and I don't see how he possibly can keep from making mistakes. We're going up shortly, anyway, so please don't let him get into any of those inspection ports, if they're really open." The girl spoke as pleasantly as ever, but 186 CLOSE TO CRITICAL.

there was a note of firmness which no human being who heard her could mistake. Raeker was surprised, and then indignant.

"What do you mean, you'd 'rather not' have Nick work? Who else can? If you think he's ignorant of elec- tricity, what good will it do for you to take over-or Swift? This plan has been under way for weeks, and you can't-"

"I don't care how long it's been organized, and I can" replied the girl, still politely. "Swift will do what I ask, and Nick will do what Swift orders. We're going to try Swift's idea first; I'm sure it will work, but if it doesn't perhaps we'll think about yours again."

Raeker looked around helplessly; the kid was right. There was no way in the universe for him to enforce his will. Maybe her father-no; Rich was listening in the communication room, and the relay screen showed something like an expression of satisfaction on his face. The biologist surrendered.

"All right, Easy. Will you tell me what this plan of Swift's is? And how, if you don't trust me and Nick, you can possibly consider an ignorant savage like one of these cave dwellers worth listening to?"

"Your scientific friends do," Easy replied pointedly. "If I tell you, 'Mina's father will hear, and he 1.!! start thinking of things wrong with it, and that'll get Dad worried. You just watch; it won't be long now."

"How does your young friend feel about not telling his father?"

"He doesn't mind, do you, 'Mina?"

"No," piped the young Drommian. "Dad told me to do what Easy said, and besides, he was rude to her.

We'll show him!"

Raeker raised his eyebrows at this, and somehow felt a little happier about the whole matter. If someone was going to make a fool of Aminadabarlee . . .

And then Swift's plan became perfectly obvious. A Capitulation; Operation; Elevation 187 group of hunters reappeared, towing among them the helpless form of a floater. The dangerous tentacles of the creature had been removed-it was obvious now why an axeman had accompanied each group- and enough of its gas cells punctured so that it could be held down; but some were still intact, and their intended use could easily be seen.

The hydrogen cells of the bathyscaphe possessed, naturally, pressure-equalizing vents on the lower side of the hull. While these vents opened into the cells on the wrong side of the plastic membrane designed to prevent hydrogen and air from mixing, the other side also had a plastic tube extending down to the same vent, for relief if too much electrolytic hydrogen was run into the cell. This tube was normally held shut, or rather flat, by outside pressure; but it was perfectly possible to push another tube into it from outside, and run gas or liquid into the compartment. This the natives proceeded to do; Raeker wasn't sure of the nature of the tube, but there was nothing surprising in their being able to improvise one. There must have been a good deal of gas wasted in the transfer process, but this didn't seem to bother anyone. There were, after all, plenty of floaters, "I see," he said through the robot after a few minutes. "But I think I see a catch.'*

"What?" Easy snapped the question with a speed which suggested she had some doubts of her own.

"That s.h.i.+p was computed around the lift of hydrogen. How do you know that stuff you're using will lift you high enough for your boosters to work, even if an engineer gets aboard to-"

"What makes you think this gas isn't hydrogen?'*

"What makes you think it is?"

"What else is lighter than water, in the gas state, that's likely to be found on this planet?"

"Why, lots of things, I guess-I-I don't know; I 188.

CLOSE TO CRITICAL.

hadn't thought of that." Realization struck him. "You've been talking to the engineers!"

"Of course. I don't mean to be rude, but where else could I learn anything useful about this s.h.i.+p? I'll admit you know the planet, but that wasn't enough."

"I see," said Raeker slowly. "I hadn't thought as much as I should about the machine; but I did ask the engineers about its wiring-and say! won't you need that anyway? What are you going to do when they get enough gas into your cells to lift the s.h.i.+p out of their reach, but not enough to get you any higher?

Hadn't you better have them tie the s.h.i.+p down, at least? You'd better wait until we-"

He was interrupted by laughter. It didn't come from Easy, who had looked impressed for a moment, but from the scientists in the observation chamber. Raeker realized that they were laughing at him, and for a moment was furious; then he realized he had asked for it. He put the best face he could on the matter while one of them carefully explained a little elementary physics.

And that, really, was all. Nick put to use the knowledge he had picked up in balancing on the experimental float, and made sure there were always more forward cells full than after ones. When the s.h.i.+p lifted, it nat- urally rode the wind toward the volcano; and it rose so slowly at first that the children had a good look at the terrifying sight. They dipped frighteningly toward the glowing mountain as it entered warmer air, but recovered in ample time as the hydrogen in its cells also warmed up. Gradually the glow faded out below them, and Easy and her friend waited happily to meet the shuttle.

EPILOGUE: COOPERATION.

"I told you human beings were helpless and useless." Happy as he was, Aminadabarlee gave up his ideas with difficulty. "You spend weeks trying to rig a rescue, and then are outsmarted by a savage with less education than either of these children. You spend a decade or two training agents of your own on the planet, and learn more useful facts in a week from natives you never bothered to contact directly."

"Natives who would have tried to eat the robot if any such attempt had been made," Easy pointed out.

"Remember, 'Mina and I know Swift. He respected the, robot because it could talk and tell him things.

He'd have ignored it or destroyed it otherwise."

Aminadabarlee's eyes sought his son, who made a gesture of agreement. "Well, anyway, the natives with their own culture are a lot more use, and I'll prove it soon enough."

"How?" asked Raeker.

"I'll have a Drommian project here in three months. We can talk to Swift as well as you, and we'll see who learns more about geophysics in general and Tenebra in particular after that."

"Wouldn't it be more profitable to run the projects jointly, and exchange information?"

"You'd certainly have to say that," sneered the non-human. "I've had enough of cooperation with human beings, and so has the rest of Dromm, if my opinion's good for anything. You learned Swift's language, didn't you, son?"

"Yes, Dad, but-"

"Never mind the but. I know you like Easy, and I suppose she's a little less poisonous than most human beings after the time she spent with you, but I know what I'm talking about. Here-use the robot voice and 189.

**kl^^.

190 CLOSE TO CRITICAL call Swift over to it; you can say something to him for me."

"But I can't, Dad." Even the human beings could see that the youngster was uncomfortable.

"Can't? What do you mean? You just said you'd learned enough of their language-"

"Oh, I understand it well enough. I just can't speak it."

"You mean you just listened, and let that human girl do all the talking? I'm ashamed of you. You know perfectly well that no chance to learn the use of a new language should ever be missed."

"I didn't miss it, Dad." Aminadabarlee seemed to swell slightly.

"Then, in the name of both suns, tell me what you did do!" His voice came closer to a roar than anyone in the room had ever heard from him. Aminadorneldo looked a little helplessly at Easy.

"All right, 'Mina," the girl said. "We'll show him."

The two took their places before the microphone, which Easy snapped on. Then, keeping their eyes fixed on each other, they began to speak in unison. The sounds they produced were weird; sometimes both were together, sometimes the Drommian carried a high note alone, somtimes Easy took the deeper registers. A similar sound, which Raeker recognized perfectly well and understood slightly, came from the speaker; Easy started an answer, using her hands to guide her "little" companion on what words were coming next.

They had apparently worked out a fairly satisfactory deaf-mute code between them; and While they spoke much more slowly than Swift, they were obviously perfectly clear to the native.

"He's here, Councillor," Easy remarked after a moment. "What did you want to say to him? This particular translating team is ready to go to work. I do hope you'll forgive 'Mina for cooperating with a human being.

There really wasn't any other way, you know."

n.o.body laughed.
