“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 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 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.
