Star Light m-2

by Hal Clement

  “But isn’t Mesklin a Type Three, by your description? You must know a lot about it by now; you’ve been in touch with our people for something like ten years, and some of you have even landed at the Rim, I mean the equator.

  “More like fifty of our years. The trouble is that Mesklin isn’t a Type Three. It’s a peculiar Two. It would have had all the hydrogen of any Jovian world if it hadn’t been for its rotation, that terrific spin which gives your world an eighteen-minute day and a shape like a fried egg. There aren’t any others like it which we’ve found yet, and no intermediate cases that anyone’s recognized, or at least that I’ve heard of That’s why the Community races were willing to go to so much trouble and effort and spend so much time building up contact with your world and setting up this expedition to Dhrawn. We’ll find out a good deal in thirty years or so about that world’s makeup from the neutrino counters in the shadow satellites but the seismic equipment you people have been planting will add a lot of detail and remove a lot of ambiguity So will your chemical work. In five or six of your years we may know enough about that rock ball to make a sensible guess why it’s there or at least, whether it ought to be called a star or a planet.”

  “You mean you only made contact with the people of Mesklin so you could learn more about Dhrawn?”

  “No, I didn’t mean that at all. People are people and worth getting to know for their own sake — at least, both my parents feel that way, though I’ve met folks who certainly don’t. I don’t think the idea for the Dhrawn project got started until long after your College was under way My mother or Dr. Aucoin could tell you when. It was long before I was born. Of course, when it dawned on someone that you folks could make first-hand investigation of a place like Dhrawn, everyone jumped at the chance.”

  This, of course, forced Beetchermarlf to ask a question which he would ordinarily have regarded as a strictly human affair and none of his business, like the matter of how mature a five-year-old should be. It slipped out before he caught himself; for over an hour thereafter he and Benj were arguing over the reasons for such activities as the Dhrawn project and why such a vast amount of effort should be devoted to an activity with no obvious material return in prospect. Benj did not defend his side too well. He was able to give the usual answers about the force of curiosity, which Beetchermarlf could see up to a point; he knew enough history to have heard how close man and several other species had come to extinction from energy starvation before they had developed the hydrogen fusion converter; but he was too young to be really eloquent. He lacked the experience to be able to point out convincingly, even to himself, the complete dependence of any culture on its understanding of the laws of the universe. The conversation never became heated, which would have been difficult in any argument where there is a built-in cooling-down period between any remark and its answer. The only really satisfactory progress made was in Benj’s mastery of Stennish.

  The discussion was interrupted by Beetchermarlf’s suddenly becoming aware of a change in his surroundings. For the last hour his entire attention had been on Benj’s words and his own replies. The canted bridge and gurgling liquid had receded to the far background of his mind. He was quite surprised to realize abruptly that the pattern of lights twinkling above him was Orion. The fog had gone.

  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 war 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 nonentities 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 principal 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 positi
on 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 assignments. 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 Beetchermarlf’s 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 Kwembly’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 bumps, 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 Kwembly 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 space 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 Kwembly’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 swiveled 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 Kwembly laboring to remove boulders from the region of the main air lock.

  The breathing sui
ts 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 assumed 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 assemblies. 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 shell was no disparagement to them, considering the general nature of Mesklinite tissue.
