“All the tools we have are in use. There would be no way for me to help outside if I did go, and it would take me longer to get reports from Reffel
through your people. Perhaps you can tell me how his search for Kervenser is coming on. I assume that nothing meaningful has turned up, since the light from his flier is still visible from here and his flight pattern has not changed. Perhaps there is description you could pass on to me. I’d like to know as much about this region as possible.”

I assume that nothing meaningful has turned up, since the light from his flier is still visible from here and his flight pattern has not changed. Perhaps there is description you could pass on to me. I’d like to know as much about this region as possible.”
Easy once again stifled an exclamation before it could be noticed by Benj. As the boy shifted his attention to the screen carrying the helicopter’s signal, she wondered whether Dondragmer were merely trying to keep her son out of his figurative hair or whether he had some real grasp of the human need to be busy and feel useful. The latter seemed unlikely but even Easy Hoffman, who probably knew Mesklinite nature better than any other human being then alive, was not sure.
Benj had not been watching the other screen at all and had to ask whether anything had been happening. One of the observers replied briefly that all anyone had seen had been a surface of pea-to-house-sized cobbles, interrupted by frozen pools similar to the one holding the
Kwembly.
There had been no sign of the other helicopter or its pilot. No one really expected any for some time. The search had to be slow to be complete. If Kervenser had actually crashed this close to his starting point the accident would probably have been seen from the cruiser. The little fliers did carry lights and Kervenser had certainly been using his.

Benj relayed this information to Dhrawn, then threw in an obvious question of his own.
“Why is Reffel making such a slow and careful search so close to you? Wasn’t Kervenser at least watched out of sight?”
The delayed response provided a little relief for the boy’s feeling of helplessness.
“He was, Benj. It seemed more reasonable to make a complete coverage centering here and starting outward, which would also have the advantage of providing more complete data for your scientists. If they can wait for the information, please tell Reffel I said to fly straight west along the valley until he can just see my bridge light, then resume the search pattern at that point.”
“Sure thing, Captain.” The conversation had been in Stennish, so none of the watching scientists had understood it. Benj did not bother to ask their approval before passing on the order in the same language. Reffel seemed to have no trouble understanding Benj’s accent and in due course his little machine headed west.
“And what’s happening to our map?” growled a topographer.
“You heard the captain,” replied Benj.
“I heard something. If I’d understood it I’d have entered an objection but I suppose it’s too late now. Do you suppose when they return they’ll fill in the gap they’re leaving now?”
“I’ll ask Dondragmer,” the boy replied obligingly, but with an uneasy
glance toward his mother. She had put on the unreadable expression which he could read all too well. Fortunately, the scientist was already leaving the communication room growling under his breath; and fortunately Benj turned his attention back to Reffel’s screen before Easy lost her gravity. Several other nearby adults who had gleaned the substance of the conversation with Dondragmer were also having trouble keeping their faces straight. For some reason they all enjoyed putting one over on the scientific group. But Benj failed to notice. He was still worried about Beetchermarlf.

Dondragmer’s assurance that lack of hydrogen would not be an immediate problem had helped but the idea of the crewmen being frozen solidly into the ice was still bothersome. Even if this took longer to happen under the
Kwembly
’s hull, it would happen at last. It might even have happened already. It should be possible do
something.

Heat melts ice. Heat is energy. The
Kwembly
carried enough energy to lift her out of Dhrawn’s gravity well, though there was no way to apply it to that task. Didn’t the huge vehicle have any sort of heaters in its life-support equipment which could be disassembled and used outside?

No. The Mesklinites were unlikely ever to need heat on Dhrawn. Even the parts of the planet where internal heat seemed to be lacking were kept close to fifty degrees absolute by the sun. The regions they would have most to do with for many years yet, such as Low Alpha’s center, were too hot rather than too cold for them. The
Kwembly
did have refrigeration equipment powered from its fusion converters but as far as Benj knew, it had never been used since the original testing. It was expected to be useful during penetration of the central part of Low Alpha, not scheduled for at least an Earth year yet, possibly even later. The fate of the
Esket
had made some of the original plans rather shaky.

But a refrigerator is a heat pump. Even Benj knew that and at least in theory, most pumps are reversible. This one must have, somewhere outside the cruiser’s hull, a high-temperature section for dumping heat. Where was it? Was it removable? At what temperature did it run? Dondragmer must know. But wouldn’t he have thought of this already? Maybe not. He was far from stupid, but his background wasn’t human. What physics he knew had been picked up from non-Mesklinites long after he was adult. It would not, presumably, be part of the basic stock of knowledge which most intelligent beings lump under the concept of “common sense.” Benj nodded at this thought, spent another second or two reminding himself that even if he made himself look silly this might be worth it and reached for his microphone switch.
This time there was no amusement among the surrounding adults as the message pulsed toward Dhrawm. None of those present knew enough about the engineering details of the land-cruisers to answer the questions about the refrigerator heat-dump, but all knew enough physics to be annoyed with themselves for not having thought of the question earlier. They waited for Dondragmer’s answer with as much impatience as Benj.
“The refrigerator is one of your solid-state electronic devices which I don’t pretend to understand in detail,” the captain’s words finally reached the station. He was still using his own language, to the annoyance of some of the listeners. “We haven’t had to use it since the acceptance tests; the weather here has sometimes been pretty warm, but not really unbearable. It’s a simple thing to describe; there are metal plates in all the rooms which get cold when we turn the power on in the system. There is a metal bar, a sort of loop, running along each side of the hull up at the top. It starts near the stern, runs forward about half a body-length to the port side of the center-line, crosses over about four body-lengths back of the bridge and goes back along the other side to a point even with its start. It runs through the hull at start and finish, one of the few things that does. I assume that bar must be the heat radiator. I see, as you imply I should, that there must be such a part to the system and that it must be outside. Nothing else seems to qualify. Unfortunately, it couldn’t be further from the ice than it is, even if it runs hot enough to melt it, which I don’t know, offhand. I realize that it could be made as hot as you please by running enough electricity through it but I’m not sure I like the idea of trying to take if off the hull for such a purpose.”
“I suppose it would wreck your refrigeration system, especially if you couldn’t get it back,” agreed Benj. “Still, maybe it’s not that bad. Let me find an engineer who really knows that system. I have an idea. I’ll call you back later.” The boy slid out of his seat without waiting for Dondragmer’s reply, and left the communication room on the run.
The moment he was gone, the observers who had not understood the language asked Easy for a summary of the conversation, which she gladly supplied. When Benj returned with an engineer in tow, those in hearing frankly abandoned their jobs to listen. Several heartfelt prayers of thanksgiving must have ascended when it was noted that the newcomer was not a linguist, and the boy was interpreting for him. The two settled into seats before the screens, and Benj made sure he knew what to say before energizing his microphone.
“I should tell the captain that most of the fastenings holding the radiator bar to the
Kwembly’
s skin are sort of nails; they only go a little way into the skin and can be pried out without damaging the hull. It might be necessary to use cement to fasten them back in afterward but the supplies are there. The connections at the rear will have to be cut, though. The alloy isn’t very hard and saws will be able to handle it. Once detached, the bar can be used as a resistance heater simply by pushing its ends into the D.C. holes in a power box. I can tell the captain that there is no danger from a short circuit, since the converters have internal safeties. Is that right, Mr. Katini?”

“That’s it,” the small, grizzled engineer replied with a nod. He was one of those who had helped design and build the land-cruisers and one of the very few human beings actually to spend much time at Mesklin’s three-gravity equator. “I don’t think you’ll have any trouble making it clear to Dondragmer, even
without translation; I’ll tell him directly if you wish. He and I always got along easily enough in my own language.”
without translation; I’ll tell him directly if you wish. He and I always got along easily enough in my own language.”
Benj nodded acknowledgment of this, but started speaking into his microphone in Stennish. Easy suspected that he was showing off and hoped that it wouldn’t backfire on him too badly but saw no real need to interfere. She had to admit that he was doing a good job of the translation. He must have picked up a great deal from his friend Beetchermarlf. In some ways he was doing better than she would have herself; he was using analogies which should be meaningful to the captain but which would not have occurred to her.
When the captain’s answer came back it was in the human tongue. Dondragmer had seen the most probable reason why Benj, rather than the engineer who had provided the information, should be doing the talking. The boy looked a little startled, and confirmed his mother’s suspicions by glancing quickly at her. She carefully kept her eyes on Dondragmer’s screen.
“I have the picture,” the Mesklinite’s slightly accented voice came through. He was not always perfectly successful in confining his voice to the human audibility range. “We can detach the refrigerator bar and use it, with a power box, as a heater to melt the ice around the ship. There will be plenty of power in the converter and no danger of blowing it up. Please clear up two points, however.
“First, how can we be sure that we can reconnect the bar electrically afterward? I know enough to doubt that cement is the right method. I don’t want to lose the refrigerator system permanently, since Dhrawn is approaching its sun and the weather will be getting warmer.
“Second, with the metal carrying a current touching the ice, or dipping into the melted water, will there be any danger to people on, in, or under that water? Will the air suits be protection enough? I suppose they must be pretty good electrical insulators, since they are transparent.”
The engineer began to answer at once, leaving Benj to wonder what connection there might be between transparency and electrical conductivity and how Dondragmer, with his background, happened to be acquainted with it.
“You can make the connection easily enough. Simply have the metal ends pressed tightly together and use the adhesive to fasten a wrapping of fabric around the joint. You’re right about the glue’s conductance; make sure it doesn’t get between the metal surfaces.
“Also, you needn’t worry about electrocuting anyone in an air suit. They’ll be adequate protection. I suspect that it would take a lot of voltage to hurt you people anyway, since your body fluids are non-polar, but I have no experimental proof and I don’t suppose you want any. It occurred to me that you might do better by striking an arc at the surface of the ice, which should have enough ammonia to be a fair conductor. If it works at all, it should work very well. Only it may be too hot for any of your men to stay in the neighborhood and it
would
have to be controlled carefully. Come to think of it, the procedure
would destroy too much of the bar to let you get the system together again afterward. We’d better stick to simple resistance heating, and be satisfied with melting the ice rather than boiling it.” Katini fell silent, and waited for Dondragmer’s answer. Benj was still thinking, and all the others within hearing had their eyes fixed on the captain’s screen. His shift of language had attracted even those who might otherwise have waited patiently for a translation.

This was unfortunate from the human viewpoint. Barlennan, later, wrote it off as a stroke of luck.
“All right,” Dondragmer’s answer finally came. “We will take off the metal bar and try to use it as a heater. I am now ordering men outside to start detaching the small brackets. I will have one of the communicators set up outside so that you can watch as we cut through the conductors, and check everything before we turn on power. We will work slowly, so that you can tell us if we are doing something wrong before it has gone too far. I don’t like this situation—I don’t like doing anything when I am so unsure of what is happening and what is likely to happen. I’m supposed to be in command here and I can only wish I had learned more of your science and technology. I may have an accurate picture as far as it goes and I’m sure I can trust your knowledge and judgment for the rest but it’s the first time in years I’ve been so uncertain of myself.”
It was Benj who answered, beating his mother by a fraction of a second.
“I heard you were the first Mesklinite to grasp the general idea of real science and that you were the one who did most to get the College going. What do you mean, you wish you had learned more?”
