“It’s about this way you plan to back off the rock, Don,” she began. “We don’t have the whole picture here, of course, but there are two things bothering our engineers. One is the fact that your forward truck will run off the stone while you still have ten feet or more of hull, including some of your bridge, over it. Have you measured to see whether there’s any risk of bare hull slamming down on the stone as the truck rolls off? Also, toward the end of the maneuver, you’ll have your hull supported almost entirely at the ends. The pneumatic undercarriage may distribute the load but my friend here isn’t sure it will; further, if you get the bare hull instead of the mattress taking half the Kwembly’s weight, Dhrawn’s gravity is going to make a very respectable effort to break your land-ship in half. Have you checked those points?” Dondragmer had to admit to himself that he had not and that he had better do so before the project went much further. He conceded this on the radio, thanked Easy and her friend, and headed for the main lock, long since cleared for use. Outside, the current had dropped to the point where lifelines were no longer necessary. Water depth was down to about seven feet, measured from the average level of the smallest boulders. The water line was, indeed, at about the most inconvenient possible level for seeing the whole picture. He had to climb part way up the rock, a difficult task in itself, though helped by the fact that he had some buoyancy; from there he had to follow the forward trucks to a point where he could compare the curvature of the big boulder and that of the Kwembly’s lower bow. He could not be completely sure, since moving the hull backward would change its pitch, but he did not like what he saw. The human engineer was probably right. Not only was there risk of hull damage, but the steering bar came through the hull just ahead of the mattress by means of a nearly air-tight mechanical seal backed by a liquid trap and made its key connections with the maze of tiller-ropes. Serious damage to the bar would not actually cripple the vehicle, since there was a duplicate aft, but it was not a risk to be taken casually. The answer to the whole situation was staring him in the face by that time but he was another hour or more in seeing it. A human psychologist, when he heard about this later, was very annoyed. He had been looking for significant differences between human and Mesklinite minds, and was finding what he considered an undue number of points of similarity. The solution involved work, of course. Even the smallest boulders were heavy. Still, they were numerous, and it was not necessary to go far for a plentiful supply. With the entire crew of the Kwembly at the job except for Beetchermarlf and those still helping him with the trucks, a ramp of piled stones grew with fair speed from the stern of the trapped vehicle toward the key rock. It was a help to Beetchermarlf. As fast as he readied a damaged bearing unit for service, he found himself able to get at new installation sites which had been out of reach before. He and the stone-carriers finished almost together, allowing for four trucks which he had been unable to repair because of missing parts. He had made thrifty use of these, cannibalizing them for the needs of some of the others, and had spotted the unavoidable gaps in traction widely enough to keep the cruiser’s weight reasonably well distributed. To work on Row 5, practically buried in the river bottom, he had had to deflate that part of the mattress. Pumping it up again when the two trucks were replaced caused the hull to shift slightly, to the alarm of Dondragmer and several workers underneath; fortunately the motion was insignificant. The captain had spent most of the time shuttling between the radio, where he kept hoping for a reliable prediction of the next flood, and the work site, where he divided his attention between the progress of the ramp and the view upstream. By the time the ramp was complete the water was less than a yard deep, and the current had ceased entirely; they were in a pool rather than a stream. It was now full night; the sun had been gone for nearly a hundred hours. The weather had cleared completely, and workers outside could see the violently twinkling stars. Their own sun was not visible; it was barely so at the best of times this deep in Dhrawn’s heavy atmosphere, and at the moment was too close to the horizon. Not even Dondragmer knew offhand whether it was slightly above or slightly below. Sol and Fomalhaut, which even the least informed of the crew knew to be indicators of south, glowed and wavered over a low eminence a few miles in that direction. The imaginary line connecting the two had tilted less than twenty degrees, human scale, since dark; the Mesklinite navigators would have said less than four. Outside the range of the Kwembly’s own lights it was almost totally black. Dhrawn is moonless; the stars provide no more illumination than they do on Earth or Mesklin. Temperature was nearly the same. Dondragmer’s scientists had been measuring the environment as completely as their knowledge and equipment allowed, then sending the results to the station above. The captain had been quietly hoping for some useful information in return, though he realized that the human beings didn’t owe him any. The reports, after all, were simply part of the job the Mesklinites had engaged to do in the first place. He had also suggested to his own men that they try some independent thinking. Borndender’s answer to what he regarded as sarcasm had been to the effect that if the human beings would supply him with reports from other parts of Dhrawn and with computer time with which to correlate them, he would be glad to try. The captain had not intended sarcasm; he knew perfectly well the vast difference between explaining why a ship floats on water or ammonia and explaining why 2.3 millicables of 60–20 rain fell at the Settlement between Hour 40 and Hour 100 of Day 2. He suspected that his researcher’s misinterpretation had been deliberate; Mesklinites were often quite human when in search of excuses and Borndender was currently feeling annoyed with his own lack of usefulness. Without bringing this aspect of the matter into the open, the captain merely repeated that useful ideas would be welcome, and left the lab. Even the scientists were ordered outside when the time finally came to use the ramp. Borndender was irritated at this and muttered something as he went about the academic nature of the difference between being inside the Kwemb/y and outside her if anything drastic happened. Dondragmer, however, had not made a suggestion; he had issued an order, and not even the scientists denied either his right or his competence to do so. Only the captain himself, Beetchermarlf, and a technician named Kensnee in the life-support compartment were to be aboard when the start was made. Dondragmer had considered acting as his own helmsman and taking a chance on the life equipment but reflected that Beetchermarlf knew the tiller cable layout better and was more likely to sense anything going wrong in that department. Inside power was not directly concerned with motion, but if any slip or collapse of the ramp caused trouble with the life-support system it was better to have someone on hand. This support system was even more important than the cruiser: in an emergency the crew could conceivably walk back to the Settlement carrying their air equipment even if the cruiser were ruined. The reasoning behind the evacuation order should have left Beetchermarlf and Kensnee as the only ones aboard, with even the captain watching from outside. Dondragmer was not prepared to be so reasonable. He had stayed aboard. Tension in the crowd of caterpillarlike beings gathered outside the monster hull mounted as the drivers took up the slack in their treads. Because Dondragmer could not see the tense crowd from the bridge, he was calm; Beetchermarlf could feel their mood and was perturbed. The human watchers, observing by way of a set which had been taken from the life-support room and secured on a rock projecting from the water a hundred yards from the land-cruiser, could see nothing until the cruiser actually started to move. They were all calm except Easy and Benj. The boy was paying little attention to the outside view, instead he was watching the bridge screen on which part of Beetchermarlf was visible. He had one set of chelae on the tiller, holding it fast; the other three sets were darting with almost invisible speed among the grips of the engine control lines, trying to equalize the pull of the different trucks. He had made no attempt to power more than the usual ten; the cords which normally cross-connected them, so that a single line would work them all, had been realigned for individual control. Beetchermarlf was very, very busy. As the K
wembly began to inch backward, one of the human beings commented explosively. “Why in blazes didn’t they put remote controls, or at least torque and thrust indicators, on that bridge? That poor bug is going crazy. I don’t see how he can tell when a particular set of tracks is even gripping, let alone how it responds to his handling.”
“If he had fancy indicators he probably couldn’t,” replied Mersereau. “Barlennan wanted no more sophisticated gear on those vehicles than his people could repair on the spot, except where there was really no choice. I agreed with him, and so did the rest of the planning board. Look — she’s sliding off, smooth as ice.” A chorus of expressive hoots came from the speaker, muffled by the fact that most of the beings emitting them were under water. For a long moment, a score or so of the ’midship trucks were hanging free as the stern of the Kwembly came off the ramp and moved back over the river bed. The engineer who had been afraid of the bridge effect crossed his fingers and rolled his eyes upward. Then the bow dipped as the forward trucks came down onto the ramp in their turn, and weight was once more decently distributed. The twisting stress, which no one had considered seriously, lessened as the cruiser eased onto the relatively level cobbling of the river bed and came to a halt. The crew divided and poured around bow and stern to get to the main lock, no one thinking to pick up the communicator. Easy thought of reminding the captain, but decided that it would be more tactful to wait. Dondragmer had not forgotten the instrument. As the first members of the crew emerged from the inner surface of the lock pool, his voice echoed through the speaking tubes. “Kervenser! Reffel! Take the scout fliers out at once. Reffel, pick up the communicator outside; make sure the shutter is in the flier before you start; then make a ten-minute sweep north to east and back. Kervenser, sweep west and around to south for the same time. Borndender, report when all your measuring equipment is aboard. Beetchermarlf and Takoorch, outside and realign the engine control cords to normal.? His communicator at the bridge had the sound on, so Easy heard and translated these orders, though the reference to a shutter meant nothing to any of them. She and her colleagues watched the screen of the outside set with interest as the two tiny helicopters rose from the upper lock, one of them sweeping toward the pickup and presumably settling outside its field of view. The other was still climbing as it left the screen, heading west. The picture rocked as the set was picked up by Reffel and wrestled into its space aboard the flier. Easy flicked a switch absent-mindedly to record the scenes for future map work as the viewpoint lifted from the ground. Dondragmer would have appreciated being able to watch the same screen but could only wait for a relayed verbal report from Reffel or a delayed but direct one from Kervenser. Actually, Reffel did not bother to relay. The ten-minute flights produced no information demanding speedy delivery. What it amounted to, as Dondragmer reported to the human audience, was that the Kwembly was in a valley some fifteen miles wide, with walls of bare rock quite steep by Dhrawn’s standards. The pilots estimated the slope at twenty to thirty degrees. They were also remarkably high, fully forty feet. To the west there had been no sign of a new flood as far as Kervenser had flown. He noted that the boulders strewing the valley floor gave way to bare rock within a mile or two and there were numerous pools like the one in which the Kwembly was now standing. To the east, the stones and pools continued as far as Reffel had gone. Dondragmer pondered these data for a while after relaying this information to the satellite, then ordered one of the fliers back to work. “Kerv, get back aloft. The helmsmen won’t be done for hours yet. Go as far west along the valley as you can in an hour and check as closely as your lights will allow for any sign of more water starting down. Make that three hours, unless you have a positive finding, of course, or have to turn back because of bad visibility. I’m going off watch. Tell Stakendee to take the bridge before you leave.” Even Mesklinites get tired but Dondragmer’s thought that this was the right time to get some rest was unfortunate, as Barlennan pointed out to him later. When the captain insisted that there would have been nothing for him to do even if he had been fully alert, his superior gave the Mesklinite equivalent of a snort of contempt. “You’d have managed to find something. You did later.” Dondragmer refrained from pointing out that this proved that his omission was not a serious error; but he had to admit to himself that it had appeared so at the time. It was almost eight hours after Kervenser’s departure that a crewman hooted outside the door of the captain?s quarters. When Dondragmer responded, the other squeezed the situation into a single sentence. “Sir, Kervenser and the helmsmen are still outside, and the pool of water we’re in has frozen.”
6: POLICY
Impatience and irritation were noticeable in the Planning Laboratory but so far no tempers had actually been lost. Ib Hoffman, back for less than two hours from a month-long errand to Earth and Dromm, had said practically nothing except to ask for information. Easy, sitting beside him, had said nothing at all so far, but she could see that something would have to be done shortly to turn the conversation into constructive channels. Changing the Project’s basic policy might be a good idea, it often was. But right now, it was futile for the people at this end of the table to spend time blaming each other for the present one. Still less useful was the scientists’ bickering at the other end. They were still wondering why a lake should freeze when the temperature had been rising. A useful answer might lead to some useful action but to Easy it seemed a question for the laboratory rather than for a conference room. If her husband didn’t take a hand in the other discussion soon, she would have to do something herself, she decided. “I’ve heard all about that side of it before, and I still don’t buy it!” snapped Mersereau. “Up to a point it’s good common sense, but I think we’re way past that point. I realize that the more complex the equipment, the fewer people you need to run it; but you also need more specialized apparatus and specially trained personnel to maintain and repair it. If the land-cruisers had been as fully automated as some people wanted, we could have gotten along with a hundred Mesklinites on Dhrawn instead of a couple of thousand at first; but the chances are that every one of these machines would be out by now because we couldn’t possibly have landed all the backup equipment and personnel they’d need. There aren’t enough technically trained Mesklinites in existence yet, for one thing. I agreed with that, Barlennan agreed with it; it was common sense, as I said. “But you, and for some reason Barlennan, went even farther. He was against including helicopters. I know there were some characters in the Project who assumed you could never teach a Mesklinite to fly, and maybe it was racial acrophobia that was motivating Barlennan; but at least he was able to realize that without air scouting the land-cruisers wouldn?t dare travel more than a few miles an hour over new ground, and it would take roughly forever to cover even Low Alpha at that rate. We did convince him on that basis. “But there was a lot of stuff we’d have been glad to provide, which would have been useful and have paid its way, which he talked us out of using. No weapons; I agree they’d probably have been futile. But no short-range radio equipment? No intercoms in the Settlement? It’s dithering nonsense for Dondragmer to have to call us, six million miles away, and ask us to relay his reports to Barlennan at the Settlement. It’s usually not critical, since Barl couldn’t help him physically and the time delay doesn’t mean much, but it’s silly at the best of times. It is critical now, though, when Don’s first mate has disappeared, presumably within a hundred miles of the Kwembly and possibly less than ten, and there’s no way in the galaxy to get in touch with him either from here or from the cruiser. Why was Barl against radios, Alan? And why are you?”
“The same reason you’ve just given,” Aucoin answered with just a trace of acerbity. “The maintenance problem.”
“You’re dithering. There isn’t any maintenance problem on a simple voice, or even a vision, communicator. There were four of them, as I understand it, being carried around on Mesklin with Barlennan’s first outside-sponsored trip fifty years or so ago, and not one of them gave the slightest
trouble. There are sixty on Dhrawn right now, with not a blip of a problem from any of them in the year and a half they’ve been there. Barlennan must know that, and you certainly do. Furthermore, why do we relay what messages they do send by voice? We could do it automatically instead of having a batch of interpreters hashing things up (sorry, Easy) and you can’t tell me there’d be a maintenance problem for a relay unit in this station. Who’s trying to kid whom?” Easy stirred; this was perilously close to feud material. Her husband, however, sensed the motion and touched her arm in a gesture she understood. He would take care of it. However, he let Aucoin make his own answer. “Nobody’s trying to kid anyone. I don’t mean equipment maintenance, and I admit it was a poor choice of words. I should have said morale. The Mesklinites are a competent and highly self-reliant species, at least the representatives we’ve seen the most of. They sail over thousands of miles of ocean on these ridiculous groups of rafts, completely out of touch with home and help for months at a time, just as human beings did a few centuries ago. It was our opinion that making communication too easy would tend to undermine that self-confidence. I admit that this is not certain; Mesklinites are not human, though their minds resemble ours in many ways, and there’s one major factor whose effect we can’t evaluate and may never be able to. We don’t know their normal life spans, though they are clearly a good deal longer than ours. Still, Barlennan agreed with us about the radio question — as you said, it was he who brought it up — and he has never complained about the communication difficulty.”
“To us.” Ib cut in at this point. Aucoin looked surprised, then puzzled. “Yes, Alan, that’s what I said. He hasn’t complained to us. What he thinks about it privately none of us knows.”
