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, 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.”

Impatience and irritation were noticeable in the Planning Laboratory, but so far no tempers had actually been lost. Ib Hoffman, back less than two hours from a month long errand to Earth and Droom, 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 for the people at this end of the table to spend time blaming each other for the present one was futile. It was even less useful than the scientists’ bickering at the other end. They were still wondering why a lake should freeze when the temperature had been going up. Such a question might conceivably have a useful answer, of course, especially if it led to a reasonable course of useful action; but it seemed to her like a question for the laboratory rather than a conference room.

If her husband didn’t take a hand in the other discussion soon, Easy 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 fully automated as some people wanted, we could have got along with a hundred Mesklinites on Dhrawn instead of a couple of thousand at first; but the 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 further. He was against including helicopters. I know there were come 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 talk him over 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?”
