Heavy Planet Part 20

Alert once more to his surroundings, he noticed that the water line around the bridge seemed just a trifle lower. Ten minutes' careful watching convinced him that this was so. The river was falling.

Part way through the ten minutes he had, of course, been queried about his sudden silence by Benj, and had given the reason. The boy had immediately notified McDevitt, so that by the time Beetchermarlf was sure about the changing water level there were several interested human beings on hand above to hear about it. The helmsman reported briefly to them on the radio and only then did he call through the speaking tubes for Dondragmer.

The captain was far aft, behind the laboratory section and just forward of the compartment containing the pressure bladder, when the call came. There was a pause after the helmsman finished speaking, and Beetchermarlf expected the captain to come bursting through the bridge hatchway after a few seconds; but Dondragmer did not yield to the temptation. The ports in the rest of the hull, including the compartment where he was, were much too small to permit a clear estimate of the water level, so he had to accept his helmsman's judgment. Dondragmer was willing to do this, rather to the young sailor's surprise.

"Keep track as exactly as you can of the rate of fall, until you are relieved," was his order. "Let me and the human beings know the rate as soon as you can guess it reliably; tell us thereafter whenever you change your estimate."

Beetchermarlf acknowledged the order and clambered across the bridge to a point where he could mark the water line with a scratch on one of the window stanchions. Reporting the action to the captain and the human listeners, he returned to his station keeping his eyes fixed on the mark. The ripples in the liquid were several inches high, settling down only at rare intervals, hence it was some time before he could be at all sure of the change in depth. There were two or three impatient queries from above, which he answered politely in the best he could muster of his limited human language, before Benj reported that he was once more alone except for nonent.i.ties watching other cruisers. Most of the time thereafter until Takoorch arrived as bridge relief was spent by the two in describing their home worlds, correcting each other's misconceptions about Earth and Mesklin by way of language practice and, though neither was fully aware of it, developing a warm personal friendship.

Beetchermarlf returned six hours later to let Takoorch go (actually the interval was twenty-four days by Mesklinite reckoning, a standard watch length) and found that the water was down nearly a foot from his reference mark. Takoorch informed him that the human Benj had just returned from a rest period. The younger helmsman wondered privately just how soon after Tak's arrival the other had found it was time to take a rest. Naturally he could not ask such a question, but as he settled back into his station he sent a call radiating upward.

"I'm back on, Benj. I don't know how recently Tak made a report to you, but the water is down over half a body length and the current seems much slower. The wind is nearly calm. Have your scientists anything to report?"

He had time during the answer delay to realize that the last question had been rather pointless, since the princ.i.p.al news wanted from the human scientists was the probable duration of the river, but there was nothing to be done about it now. Besides, maybe they did have something of value.

"Your friend Takoorch did tell us about the water and wind, among a good many other things," Benj's voice announced. "It's good to have you back, Beetch. I haven't heard anything from the labs, but it seems to me from what you've said about the way you're tipped and the rate the water's been dropping, and from what I can judge from the cruiser model I have here, that another sixty or seventy hours should leave you dry. That's if the water keeps dropping at the same rate, of course. It might do that if it's flowing away through a nice smooth channel but I wouldn't count on that. I hate to sound pessimistic but my guess is that it will slow down before all the liquid is gone."

"You may be right," agreed Beetchermarlf. "On the other hand, with the current easing off we can probably work outside safely enough before it's all gone." This was a prophetic remark. It was still on its way to the station when a speaking tube hooted for attention.

"Beetchermarlf! Inform the human beings that you will be relieved immediately by Kervenser, and report at once to the starboard after emergency lock in your air suit. I want a check of the trucks and tiller lines. Two others will go with you for safety. I am more interested in accuracy than speed. If there is any damage which would be easier to fix while we are still tilted than it would be after we are level, I want to know about it. After you make that check, take a general look around. I want a rough idea of how solidly we are wedged into this position and how much work it will take to level us and get us loose. I will be outside myself making a similar check, but I want another opinion."

"Yes, sir," the helmsman responded. He almost forgot to notify Benj, for this time the order was a distinct surprise, not the fact that he was to go outside, but that the captain had chosen him to check his own judgment.

The air suits had been removed when Dondragmer was convinced that the hull was sound, but Beetchermarlf was back into his in half a minute and at the designated lock moments later. The captain and four sailors, all suited, were waiting. The crewmen held coils of rope.

"All right, Beetch," greeted the captain. "Stakendee will go out first and attach his line to the handiest climbing grip. You will follow, then Praffen. Each of you will attach his line to a different grip. Then go about your a.s.signments. Wait-fasten these to your suit harness; you'll float without ballast." He handed four weights equipped with quick-release clips for harness attachment to the helmsman.

Egress was made in silence through the tiny lock. It was essentially a U-shaped liquid trap, fundamentally similar in operation to the main one and deep enough so that the Kwembly's tilt did not quite spoil its operation. The fact that the outer end was in liquid anyway may have made the difference. Beetchermarlf, emerging directly into the current, was glad of Stak's steadying grip as he sought anchorage for his own safety line.

A minute later the third member of their group had joined them, and together they clambered the short distance that separated them from the river bottom. This was composed of the rounded rocks which had been visible from the bridge, arranged in an oddly wavelike pattern whose crests extended across the direction of the current. At first glance, Beetchermarlf got the impression that the cruiser had stranded in the trough between two of these waves. Enough of the outside lights were still working to make seeing possible, if not quite ideal.

The trio made their way around the stern to get a look at their vehicle's underside. While this was much less well lighted, it was obvious at once that there would be a great deal to report to Dondragmer.

The Kwembly had been supported by a set of sixty trucks, each some three feet wide and twice as long, arranged in five longitudinal rows of twelve. All swiveled on casters and were interconnected by a maze of tiller ropes which were Beetchermarlfs main responsibility. Each of the trucks had a place to install a power unit, and had its own motor consisting of a six-inch-thick shaft whose micro-structure gave it a direct grip on the rotating magnetic field which was one of the forms in which the fusion units could deliver their energy. If no power box was installed, the truck rolled free. At the time of the accident, ten of the Kwemb/y's twenty-five converters had been on trucks, arranged in point-forward V patterns fore and aft.

Eighteen trucks from the rear of the cruiser, including all five of the powered ones at that end, were missing.

5: FRYER TO FREEZER.

Strictly speaking, all of them weren't missing. Several could be seen lying on the boulders, evidently dislodged at the time of the final impact. Whether any had gone with the earlier b.u.mps, presumably miles upstream, Beetchermarlf could not guess and was rather afraid to find out. That could be checked later. Inspecting what was left would have to come first. The helmsman set to it.

The front end seemed to have sustained no damage at all; the trucks were still present and their maze of tiller lines in proper condition. Amidships, many of the lines had snapped in spite of the enormous strength of the Mesklinite fiber used in them. Some of the trucks were twisted out of alignment; several, indeed, swung freely to the touch. The pattern of missing parts aft was regular and rather encouraging. Numbering from the port side, Row 1 had lost its last five trucks; Rows 2 and 3 their last four; Row 4 the last three; Row 5, on the starboard side, its last two. This suggested that they had all yielded to the same impact, which had wiped diagonally across the bottom of the hull; and since some of the detached units were in the neighborhood, there seemed a good chance that they all would be.

The inspectors were surprised at how little damage had been done by the trucks tearing away. Beetchermarlf and his companions had had nothing to do with the design of the Kwemb/y and her sister machines. None of them had more than the roughest idea of the sort of thinking which had been involved. They had never considered the problems inherent in building a machine powered by the most sophisticated energy sources ever developed, but operated by beings from a culture still in the muscle-and-wind stage; beings who would be cut off from any repair and replacement facilities once they were on Dhrawn. This was the reason the steering was done by tiller and rope rather than by powered selsyns or similar devices; why the air locks were so simple, and not completely foolproof; why the life-support system was not only manually operated (except for the lights which kept the plants alive) but had even been designed and built by Mesklinite scientists and technicians.

A few hundred of the beings had received an extensive body of "alien" education, though no attempt had been made to spread the new knowledge through the Mesklinite culture. Nearly all of the "college graduates" were now on Dhrawn, together with recruits like Beetchermarlf; mostly young, reasonably intelligent volunteers from among the sailors of Barlennan's maritime nation. These were the people who would have to perform any repairs and all regular maintenance on the land-cruisers, and this fact had to be kept constantly in the foreground of the designers' minds. Designing vehicles capable of covering thousands of miles of Dhrawn's environment in a reasonable length of time, and at the same time reasonably safely under Mesklinite handling, had inevitably resulted in equipment with startling qualities. Beetchermarlf should not have been surprised either that the pieces of his cruiser went back together so readily, or that the cruisers had suffered so little damage.

Of course, the intelligence of the Mesklinites had been taken into account. It was the main reason for not depending on robots: these had proved unsatisfactory in the early days of s.p.a.ce exploration. Mesklinite intelligence was obviously comparable to that of human beings, Drommians, or Paneshks: a fact surprising in itself, since all four planets appeared to have evolved their life forms over widely different lengths of geological time. It was also fairly certain that Mesklinites were much longer-lived, on the average, than human beings, though Mesklinites were oddly reluctant to discuss this; indeed, what this would mean in terms of their general competence was as problematic as Dhrawn itself. It had been a risky project from all angles, with most of the risk being taken by the Mesklinites. The giant barge drifting in orbit near the human station, which was supposed to be able to evacuate the entire Settlement in emergency, was little more than a gesture, especially for the beings afield in the land-cruisers.

None of this was in the minds of the three sailors inspecting the Kwemb/y's damage. They were simply surprised and delighted to find that the lost trucks had merely popped out of the sockets in which they normally swivelled and into which they could apparently be replaced with little trouble, provided they could be found. With this problem settled to his satisfaction, Beetchermarlf made a brief cast over the river bottom to the limits imposed by the safety lines and found twelve of the trucks within that radius. Some of these were damaged: tracks broken or with missing links; bearing wheels cracked; a few axles bent. The three gathered all the material they could reach and transport and brought it back to the Kwembly's stern. The helmsman considered doubling up on the safety lines and increasing their search radius but decided to report to Dondragmer and get his approval first. Indeed, the helmsman was a bit surprised that the captain had not appeared earlier, in view of his announced intention of checking outside.

He found the reason when he and his companions went back around the stern to the lock. Dondragmer, his two companions of the original sortie and six more crewmen, who had evidently been summoned in the meantime, were near the middle of the Kwemb/y laboring to remove boulders from the region of the main air lock.

The breathing suits had no special communication equipment, and the transmissive matching between their hydrogen-argon filling and the surrounding liquid was extremely poor; but the Mesklinite voice, built around a swimming siphon rather than a set of lungs (the hydrogen-using midgets lacked lungs) was another thing which had bothered human biologists. The helmsman caught his captain's attention with a deep hoot and gestured him to follow around the stern of the cruiser. Dondragmer a.s.sumed that the matter was important and came along after directing the others to continue their work. One look and a few sentences from Beetchermarlf brought him abreast of the situation.

After a few seconds' thought he rejected the idea of looking immediately for the missing trucks. The water was still going down; it would be safer and easier to conduct the search when it was gone, if this did not take too long. In the meantime repairs could be started on the ones which had already been found. Beetchermarlf acknowledged the order and began to sort the damaged equipment in order to plan the work.

Care was necessary; some parts were light enough to be borne away by the current when detached from the rest of the a.s.semblies. Some such items were already missing, and had presumably gone in just that fashion. The helmsman had a portable light brought to the scene and stationed one of his helpers a few yards downstream to catch anything which got away from him. He thought how helpful a net would be but there was no such item aboard the Kwembly. It would be possible to make one from the miles of cordage she carried, but it hardly seemed worth the time.

Eight hours of labor, interrupted by occasional rests spent chatting with Benj, saw three of the damaged trucks again serviceable. Some of their parts were not of the original quality, Beetchermarlf and the others having improvised freely. They had used Mesklinite fabric and cord as well as alien polymers and alloys which were on hand. Their tools were their own; their culture had high standards of craftsmanship and such things as saws, hammers, and the usual spectrum of edged tools were familiar to the sailors. The fact that they were made of the Mesklinite equivalents of bone, horn, and sh.e.l.l was no disparagement to them, considering the general nature of Mesklinite tissue.

Replacing the repaired units in their swivels took muscle even by Mesklinite standards. It also took more tool work, as metal in the mountings had been bent out of shape when the trucks were torn free. The first three had to be placed in Row 4, since Row 5 was pressed against the boulders of the river bottom and the other three were too high to be reached conveniently. Beetchermarlf bowed to necessity, attached the trucks where he could, and went back to fixing more.

The river continued to fall and the current continued to decrease. Dondragmer ordered the helmsman and his helpers to move their work area from beneath the hull, antic.i.p.ating what would happen as the buoyant force on the Kwembly decreased. His caution was justified when, with a grinding of boulders, the vehicle slipped from its sixty-degree tilt to about thirty, bringing two more rows of trucks within reach of the bottom and forcing two workmen to duck between stones to avoid being crushed.

At this point it became obvious that even if the water fell farther, the cruiser would not. A point on its port underside about a third of the way back from the bow and between Rows 1 and 2 was now resting on a single rock some eighteen feet in diameter and half buried in the river bottom: a hopeless object to dislodge even without the Kwembly's weight on it. Beetchermarlf kept on with his a.s.signed job but couldn't help wondering how the captain proposed to lift his craft off that eminence. He was also curious about what would happen when and if he succeeded. The rocky surface which formed the river bed was the last sort of thing the cruiser's designers had had in mind as a substrate and the helmsman doubted seriously that she could run on such a base. High-gravity planets tend to be fairly level, judging by Mesklin, the only available example, and even if an area were encountered where traction seemed unpromising, the designers must have supposed that the crew need merely refrain from venturing onto it. This was another good example of the reason manned exploration was generally better than the automated kind.

Beetchermarlf, in a temporarily philosophical mood, concluded that foresight was likely to depend heavily on the amount of hindsight available.

Dondragmer, pondering the same problem, getting his vehicle free, was no nearer a solution than his helmsman some fifty hours after going aground. The first officer and the scientists were equally baffled. They were not worried, except for the captain, and even his feeling did not exactly parallel human "worry." He had kept to himself and Beetchermarlf (who had been on the bridge at the time) a conversation he had had with the human watchers a few hours before.

It had begun as a regular progress report, on an optimistic tone. Dondragmer was willing to admit that he hadn't thought of a workable plan yet but not that he was unlikely to think of one. Unfortunately, he had included in the remark the phrase "we have plenty of time to work it out."

Easy, at the other end, had been forced to disagree.

"You may not have as much as you think. Some of the people here have been considering those boulders. They are round, or nearly so, according to your report and what we can see on the bridge set. The most likely cause of that shape, according to our experience, is washing around in a stream bed or on a beach. Moving rocks that big would require a tremendous current. We're afraid that the stream which carried you there is just a preliminary trickle, the first thaw of the season, and if you don't get away soon you'll face a lot more water coming down."

Dondragmer had considered briefly.

"All right, but we're already doing all we can. Either we get away in time, or we don't; we can't do better than our best. If your scientists can give any sort of specific forecast of this super-flood we'll be glad of it, of course; otherwise we'll have to go on as we are. I'll leave a man on the radio here, of course, unless I have too much for them to do; in that case, try the lab. Thanks for the information, I guess."

The captain had gone back to work and to thought. He was not one to panic; in emergencies he seemed calmer than in a personal argument. Basically, his philosophy was the one he had just expressed: to do all one could in the time available, with the full knowledge that time would run out some day. At the moment, he only wished he knew what all he could do was.

The big rock was the main problem. It was keeping the drivers from traction, and until they not only touched bottom but bore heavily on it there was no moving the Kwembly with her own power. She might conceivably have been shifted by muscle power at Mesklin's Rim, or on Earth, but not under Dhrawn's gravity. Even a two-foot boulder was hard to move in that field.

There was rigging inside which could be set up as lifting tackle but none of it could begin to support the vehicle's weight as a static load even if its mechanical advantage were adequate.

Some trucks, four, to be exact, were in contact with the troublesome rock itself. Several more in Row 5 were touching bottom. None of these was powered at the moment but converters could be transferred to them. If the four on the rock, and the ones forward from them, and some of the Row 5 trucks, were all to be powered why couldn't the cruiser simply be backed off?

She could. No reason at all to doubt it. On level ground with reasonable traction any four well-s.p.a.ced power units could drive her. With her weight concentrated on only a few trucks, traction should be better than normal and a backward move would be mainly downhill.

It was not lack of self-confidence which caused Dondragmer to outline this plan to the human being on communication watch; he was announcing his intentions, not asking for advice. The man who heard him was not an engineer and gave casual approval to the move. As a matter of routine he reported the situation to Planning so that the information could be distributed. Consequently it reached an engineer within an hour or so, long before Dondragmer was ready to execute his plan.

It caused a raising of eyebrows, a quick examination of a scale model of the Kwembly, and two minutes of rapid slide-rule work.

The engineer was a poor linguist, but this was not the only reason he went looking for Easy Hoffman. He did not know Dondragmer very well, had no idea how the Mesklinite would react to criticism; he had worked with Drommians, since there were some connected with the Dhrawn project, and he felt it safest to have his point presented by the official oil-spreader. Easy, when found, promptly a.s.sured him that she had never known Dondragmer to resent reasonable advice, but agreed that her better knowledge of Stennish would probably help even though the captain was fluent in the human tongue. They went together to the communication room.

Benj was there, as was usual when he was not on duty. He had by now made friends with several more of the Mesklinites, though he still liked Beetchermarlf best. The latter's long work hours resulting from the accident had not entirely prevented them from conversing and Benj's Stennish had improved greatly; he was now almost as good as his mother believed.

When Easy and the engineer arrived, he was listening to Takoorch and was not too sorry to interrupt the exchange with the news that there was an important message for the captain.

It took several minutes to get Dondragmer to the bridge; like the rest of the crew he had been working almost constantly, though by luck he happened to be inside when the call came.

"I'm here, Easy," his voice finally came through. "Tak said you had a business call. Go ahead."

"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 Kwembly 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, m.u.f.fled 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 s.p.a.ce 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 a.s.sumed 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.

"n.o.body'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."
