15: ESSENCE

“It boils down to this,” Aucoin said from the head of the table. “We have the choice of sending down the barge, or not. If we don’t, the Kwembly and the two Mesklinites aboard her are lost, and Dondragmer and the rest of her crew are out of action until a rescue cruiser such as the Kalliff can reach them from the Settlement. Unfortunately, if we do try to land the barge there’s a good chance that it won’t help. We don’t know why the ground gave under the Kwembly, and have no assurance that the same thing won’t happen anywhere else in the vicinity. Losing the barge would be awkward. Even if we first landed near Dondragmer’s camp and transferred him and his crew to the cruiser, we might lose the barge and there is no assurance that the crew could repair the Kwembly. Beetchermarlf’s report makes me doubt it. He says he has found and sealed the major leaks, but he’s still getting oxygen inside the hull from time to time. Several of his life-support tanks have been poisoned by it. So far he has been able to clean them out each time and restock them from the others, but he can’t keep going forever unless he stops the last of these leaks. Also, neither he nor anyone else has made any concrete suggestion for getting that cruiser loose from the muck or whatever it’s stuck in.

“There is another good argument against landing the barge. If we use remote, live control, there is the sixty-second reaction lag, which would make handling anywhere near the ground really impossible. It would be possible to program its computer to handle a landing, but the risks of that were proved the hard way the first time anyone landed away from Earth. You might as well give the Mesklinites a quick lesson in flying the thing for themselves!”

“Don’t try to make that last sound too silly, Alan,” Easy pointed out gently. “The Kwembly is merely the first of the cruisers to get into what looks like final trouble. Dhrawn is a very big world, with very little known about it, and I suspect we’re going to run out of land-cruisers for rescue or any other purpose sooner or later. Also, even I know that the barge controls are computer-coupled, with push-the-way-you-want-to-go operators. I admit that even so, the chances are ten to one or worse that anyone trying a ground-to-ground flight with that machine on Dhrawn without previous experience would kill himself, but do Beetchermarlf and Takoorch have even that much chance of survival on any other basis?”

“I think they do,” replied Aucoin quietly.

“How, in the name of all that’s sensible?” snapped Mersereau. “Here all along we’ve—” Easy held up her hand, and either the gesture or the expression on her face caused Boyd to fall silent.

“What other procedure which you could conscientiously recommend would stand any real chance of saving either the Kwembly herself, or her two helmsmen, or the rest of Dondragmer’s crew?” she asked.

Aucoin had the grace to flush deeply, but he answered steadily enough.

“I mentioned it earlier, as Boyd remembers,” he said. “Sending the Kalliff from the Settlement to pick them up.

The words were followed by some seconds of silence, while expressions of amusement flitted across the faces around the table. Eventually Ib Hoffman spoke.

“Do you suppose Barlennan will approve?” he asked innocently.

“It boils down to this,” Dondragmer said to Kabremm. “We can stay here and do nothing while Barlennan sends a rescue bruiser from the Settlement. I assume he can think of some reason for sending one which won’t sound too queer, after he failed to do it for the Esket.”

“That would be easy enough,” returned the Esket’s first officer. “One of the human beings was against sending it, and the commander simply let him win the argument. This time he could be firmer.”

“As though the first time wouldn’t have made some of the other humans suspicious enough. But never mind that. If we wait, we don’t know how long it will be, since we don’t even know whether there’s a possible ground route from the Settlement to here. You came from the mines by air, and we floated part of the way.

“If we decide not to wait, we can do either of two things. One is to move by stages toward the Kwembly, carrying the life equipment as far as the suits will let us and then setting it up again to recharge them. We’d get there some time, I suppose. The other is to move the same way toward the Settlement to meet the rescue cruiser if one comes or get there on foot if it doesn’t. I suppose we’d even get there, eventually. Even if we reach the Kwembly, there is no certainty that we can repair her; if the human beings have relayed Beetchermarlf’s feelings at all adequately, it seems rather doubtful. I don’t like either choice because of the wasted time they both involve. There are better things to do than crawl over the surface of this world on foot.

“A better idea, to my way of thinking, is to use your dirigible either to rescue my helmsmen if it is decided to give up on the Kwembly, or to start ferrying my crew and equipment over to where she is.”

“But that—”

“That, of course, sinks the raft as far as the Esket act is concerned. Even using Reffel’s helicopter would do that; we couldn’t explain what happened to the vision set he was carrying without their seeing through it, no matter what lie you think up. I’m simply not sure that the trick is worth the deliberate sacrifice of those lives, though I admit it’s worth the risk, of course; I wouldn’t have gone along with it otherwise.”

“So I heard,” returned Kabremm. “No one has been able to make you see the risk of being completely dependent on beings who can’t possibly regard us as real people.”

“Quite right. Remember that some of them are as different from each other, as they are from us. I made up my mind about the aliens the time one of them answered my question about a differential hoist clearly and in detail, and threw in my first lesson in the use of mathematics in science, gratis. I realize the humans differ among themselves as we do; certainly the one who talked Ban out of sending help to the Esket must be as different as possible from Mrs. Hoffman or Charles Lackland — but I don’t and never will distrust them as a species the way you seem to. I don’t think Barlennan really does, either; he’s changed the subject more than once rather than argue the point with me, and that’s not Barlennan when he’s sure he’s right. I still think it would be a good idea to lower the sails on this act and ask directly for human help with the Kwembly. or at least take a chance on their finding out by using all three dirigibles there.”

“There aren’t three, any more.” Kabremm knew the point was irrelevant, but was rather glad of a chance to change the subject. “Karfrengin and four men have been missing in the Elsh for two of this world’s days.”

“That news hadn’t reached me, of course,” said Dondragmer. “How did the commander react to it? I should think that even he would be feeling the temptation to ask for human help, if we’re starting to lose personnel all over the map.

“He hasn’t heard about it, either. We’ve had ground parties out searching, using trucks we salvaged from the Esket, and we didn’t want to make a report until it could be a complete one.”

“How much more complete could it be? Karfrengin and his men must be dead by now. The dirigibles don’t carry life-support gear for two days.”

Kabremm gave the rippling equivalent of a shrug. “Take it up with Destigmet. I have troubles enough.”

“Why wasn’t your flyer used for the search?”

“It was, until this evening. There are other troubles at the mine, though. A sort of ice river is coming, very slowly, but it will soon cover the whole second settlement if it doesn’t stop. It’s already reached the Esket and started to tip it over; that’s why we were able to salvage the trucks so easily. Destigmet sent me to follow back up the glacier and try to find out whether it is likely to keep coming indefinitely, or was just a brief event. I really shouldn’t have come this far, but I couldn’t make myself stop. It’s this same river for the whole distance, sometimes solid and sometimes liquid along the way; it’s the weirdest thing I’ve seen yet on this weird world. There isn’t a chance of the ice’s stopping, and the Esket settlement is as good as done for.”

“And of course Barlennan hasn’t heard about this either.”

“There’s been no way to tell him. We only discovered the ice was moving just before dark. It was just a cliff a few dozen cables from the mine up to then.”

“In other words, we’ve lost not only my first officer and a helicopter but a dirigible with five men, and as an afterthought the whole Esket project, with my Kwembly probably on the same list. And you still think we shouldn’t end this trickery, tell the human beings the whole story, and get their help?”

“More than ever. If they learn we’re having this much trouble, they’ll probably decide we’re no more use to them and abandon us here.”

“Nonsense. No one just abandons an investment like this project; but never mind arguing; it’s a futile point anyway I wish—”

“What you really wish is that you had an excuse for leaking the whole barrel to your oxygen-breathing friends.”

“You know I wouldn’t do that. I’m quite ready to use my own judgment in the field, but I know enough history to be afraid of making spot-changes in basic policy.”

“Thank goodness. It’s all right to like some humans, but they’re not all like the Hoffman one. You admitted that yourself.”

“What it boils down to,” Barlennan said to Bendivence, “is that we were much too hasty in sending Deeslenver to the Esket with orders to shutter its vision sets. The whole Esket question seems to have quieted down, and that will bring it to life again. We’re not ready for the main act yet, and won’t be for a year on more. I wasn’t sorry for the chance to start the human beings thinking along the lines of a native-menace idea, but Destigmet’s crew won’t be able to play the part until they have a lot more home-made mechanical and electrical equipment, things that the humans know we don’t have. Certainly, unless the native menace seems real, the human beings aren’t very likely to take the steps we want.

“If there were any way to go after Dee now and cancel his orders, I’d do it. I wish I’d dared let you go ahead with radio experiments, and had a set on the Deedee right now.”

“It shouldn’t be too risky, and I’d be more than glad to work on it,” answered Bendivence. “The waves could be detected by the human beings, of course, but if we confined ourselves to brief and rare transmissions and used a simple off-on code they probably wouldn’t realize what the source was. However, it’s too late to get Deeslenver, anyway.

“True. I wish I knew why no one up there has said another word about Kabremm. The last time I talked to Mrs. Hoffman, I got the impression that she wasn’t quite as sure as before that she’d really seen him. Do you suppose she really made a mistake? Or are the human beings trying to test us, the way I wanted to do with them? Or has Dondragmer done something to get us off that reef. If she were really wrong, we’ll have to start thinking all over again…

“And what about that other report we’ve heard no more of, something sliding across the Esket’s floor?” countered the scientist. “Was that still another test? Or is something really happening there? Remember, we haven’t had any contact with that base for over a hundred and fifty hours. If the Esket is really being moved by something, we’re much too badly out of date to do anything sensible. You know, without saying anything against the Esket act, it’s an awful nuisance not to be able to trust your data.”

“If there’s real trouble at the Esket we’ll just have to trust Dee’s judgment,” said the commander, ignoring Bedivence’s closing sentence. “Actually, even that isn’t the chief problem. The real question is what to do about Dondragmer and the Kwembly. I suppose he had good reason to leave his ship and let her drift away, but the results have been very awkward. The fact that a couple of his men got left aboard makes it almost more so; if they hadn’t been, we could just forget about the cruiser and send out the Kalliff to pick up the people.”

“Why can’t we do that anyway? Didn’t the human Aucoin suggest it?”

“He did. I said I’d have to think it over.

“Why?”

“Because there is less than one chance in ten, and probably less than one in a hundred, that the Kalliff could get there in time to do those two men any good. The chances are small enough that she could get there at all. Remember that snow field the Kwembly crossed before her first flood? What do you suppose that area is like now? And how long do you think two men, competent men, but with no real technical or scientific training, are going to keep that leaking hull habitable?

“Of course, we could confess the whole act, tell the humans to get in touch with Destigmet through the watch he keeps at the Esket’s communicators; then they could tell him to send a rescue dirigible.”

“That would be wasting a tremendous amount of work, and ruining what still seems a promising operation,” Bendivence replied thoughtfully. “You don’t want to do that any more than I do; but of course we can’t abandon those two helmsmen.”

“We can’t,” Barlennan agreed slowly, “but I just wonder whether we’d be taking too much of a chance on them if we waited out one other possibility.”

“What’s that?”

“If the human beings were convinced that we could not possibly carry out the rescue, it’s just possible, especially with two Hoffmans to do the arguing, that they’d decide to do something about it themselves.”

“But what could they do? The ship they call the ‘barge’ will only land here at the Settlement by its automatic controls, as I understand Rescue Plan One. They certainly can’t fly it around on this world from out at the orbiting station; if it took them a whole minute to correct any mistake, they’d crash it right away. They certainly can’t fly it down personally. It’s set up to rescue us, with our air and temperature control, and besides Dhrawn’s gravity would paint a human being over the deck.”

“Don’t underestimate those aliens, Ben. They may not be exactly ingenious, but there’s been time for their ancestors to think up a lot of ready-made ideas we don’t know about yet. I wouldn’t do it if I felt there was a real chance of our getting there ourselves, but this way we’re not putting the helmsmen in any worse danger than they are already; I think that we’ll let the human beings get the idea of making the rescue themselves. It would be much better than giving up the plan.”

“What it boils down to,” said Beetchermarlf to Takoorch, “is that we somehow have to find time between plugging leaks and cleaning poison out of the air units to convince people that the Kwembly is worth salvaging.

“The best way would be to get her going ourselves, though I doubt very much that we can do it. It’s the cruiser that’s going to set the policy. Your life and mine don’t mean very much to the humans, except maybe to Benj, who isn’t running things up there. If the ship stays alive, if we can keep these tanks going to supply us with food and air, and incidentally keep from being poisoned by oxygen ourselves, and make real, reportable progress in repairing and freeing the cruiser, then maybe they’ll be convinced that a rescue trip is worth while. Even if they don’t, we’ll have to do all those things for our own sakes anyway; but if we can have the humans tell Barlennan that we have the Kwembly out and running, and will get her back to Dondragmer by ourselves, it should make quite a few people happy, especially the commander.”

“Do you think we can do it?” asked Takoorch.

“You and I are the first ones to convince,” replied the younger helmsman. “The rest of the world will be easier after that.”

“What it boils down to,” said Benj to his father, “is that we won’t risk the barge for two lives, even though that’s what it’s here for.”

“Not quite right on either count,” Ib Hoffman answered. “It’s a piece of emergency equipment, but it was planned for use if the whole project collapsed and we had to evacuate the Settlement. This was always a possibility; there was a lot that just couldn’t be properly tested in advance. For example, the trick of matching outside pressure in the cruisers and air-suits by using extra argon was perfectly reasonable, but we could not be sure there would be no side effects on the Mesklinites themselves; argon is inert by the usual standards, but so is xenon, which is an effective anaesthetic for human beings. Living systems are just too complicated for extrapolation ever to be safe, though the Mesklinites seem a lot simpler physiologically than we are. That may be one reason they can stand such a broad temperature range.

“But the point is, the barge is preset to home in on a beam transmitter near the Settlement; it won’t land itself anywhere else on Dhrawn. It can be handled by remote control, of course, but not at this range.

“We could, I suppose, alter its on-board computer program to make it set itself down in other places, at least, on any reasonably flat surface; but would you want to set it down anywhere near your friend either by a built-in, unchangeable program or by long-delayed remote control? Remember the barge uses proton jets, has a mass of twenty-seven thousand pounds, and must put up quite a splash soft-landing in forty gravities, especially since its jets are splayed to reduce cratering.” Benj frowned thoughtfully.

“But why can’t we get closer to Dhrawn, and cut down the remote-control lag?” he asked, after some moments’ thought. Ib looked at his son in surprise.

“You know why, or should. Dhrawn has a mass of 3,471 Earths, and a rotation period of just over fifteen hundred hours. A synchronous orbit to hold us above a constant longitude at the equator is therefore just over six million miles out. If you use an orbit a hundred miles above the surface you’d be traveling at better than ninety miles a second, and go around Dhrawn in something like forty minutes. You’d remain in sight of one spot on the surface for two or three minutes out of the forty. Since the planet has about eighty-seven times Earth’s surface area, how many control stations do you think would be needed to manage one landing or lift-off?”

Benj made a gesture of impatience.

“I know all that, but there is already a swarm of stations down there, the shadow satellites. Even I know that they all have relay equipment, since they’re all reporting constantly to the computers up here and at any given moment nearly half of them must be behind Dhrawn. Why can’t a controller riding one of these, or a ship at about the same height, tie into their relays and handle landing and lift-off from there? Delay shouldn’t be more than a second or so even from the opposite side of the world.”

“Because,” Ib started to answer, and then fell silent. He remained so for a full two minutes. Benj did not interrupt his thinking; the boy usually had a good idea of when he was ahead.

“There would have to be several minutes of interruption of neutrino data while the relays were being preempted,” Ib said finally.

“Out of the how many years that they’ve been integrating that material?” Benj was not usually sarcastic with either of his parents, but his feelings were once more growing warm. His father nodded silently, conceding the point, and continued to think.

It must have been five minutes later, though Benj would have sworn to a greater number, that the senior Hoffman got suddenly to his feet.

“Come on, son. You’re perfectly right. It will work for an initial space-to-surface landing, and for a surface-to-orbit lift-off, and that’s enough. For surface-to-surface flight even one second is too much control delay, but we can do without that.”

“Sure!” enthused Benj. “Lift off into orbit, get your breath, change the orbit to suit your landing spot. and go back down.”

“That would work, but don’t mention it. For one thing, if we made a habit of it there would be a significant interruption of neutrino data transmission. Besides, I’ve wanted an excuse for this almost ever since I joined this project. Now I have one, and I’m going to use it.”

“An excuse for what?”

“For doing exactly what I think Barlennan has been trying to maneuver us into doing all along: put Mesklinite pilots on the barge. I suppose he wants his own interstellar ship, some time, so that he can start leading the same life among the stars that he used to do on Mesklin’s oceans, but he’ll have to make do with one quantum jump at a time.”

“Is that what you think he’s been up to? Why should he care about having his own space pilots so much? And come to think of it, why wasn’t that a good idea in the first place, if the Mesklinites don’t learn how?”

“It was, and there’s no reason to doubt that they can.”

“Then why wasn’t it done that way all along?”

“I’d rather not lecture on that subject just now. I like to feel as much pride in my species as circumstances allow, and the explanation doesn’t reflect much credit either on man’s rationality or his emotional control.”

“I can guess, then,” replied Benj. “But in that case, what makes you think we can change it now?”

“Because now, at the trifling cost of descending to the same general level of emotional reasoning, we have a handle on some of man’s less generous drives. I’m going down to the planetology lab and filibuster. I’m going to ask those chemists why they don’t know what trapped the Kwembly, and when they say it’s because they don’t have any samples of the mud, I’m going to ask them why they don’t. I’m going to ask them why they’ve been making do with seismic and neutrino-shadow data when they might as well be analyzing mineral samples carted up here from every j spot where a Mesklinite cruiser has stopped for ten minutes. If you prefer not to descend to that level, and would rather work with mankind’s no-bier emotions, you be thinking of all the heart-rending remarks you could make about the horror and cruelty of leaving your friend Beetchermarlf to suffocate slowly on an alien world parsecs from his home. We could use that if we have to take this argument to a higher authority, like the general public. I don’t think we’ll really need to, but right now I’m in no mood to restrict myself to clean fighting and logical argument. he “If Alan Aucoin growls about the cost of operating the barge (I think has too much sense), I’m going to jump on him with both feet. Energy has been practically free ever since we’ve had fusion devices; what costs is personal skill. He’ll have to use Mesklinite crews anyway, so that investment is already made; and by letting the barge drift out here unused he’s wasting its cost. I know there’s a small hole in that logic, but if you point it out in Dr. Aucoin’s hearing I’ll paddle you for the first time since you were seven, and I don’t think the last decade has done too much to my arm. You let Aucoin do his own thinking.”

“You needn’t get annoyed with me, Dad.”

“I’m not. In fact, I’m not as much annoyed as I am scared.”

“Scared? Of what?”

“Of what may happen to Barlennan and his people on what your mother calls ‘that horrible planet.’

“But why? Why now, more than before?”

“Because I’m coming gradually to realize that Barlennan is an intelligent, forceful, thoughtful, ambitious, and reasonably well-educated being, just as my only son was six years ago; and I remember your homemade diving outfit much too well. Come on. We have an astronautics school to get organized, and a student body to collect.”
