Raeker noticed that the streams of oleum were much higher in the center than at the edges, rather like greatly magnified trickles of water on waxed paper, even though they still showed a fairly distinct surface; evidently the sea had already been heavily diluted by the rain. That meant there was no point in expecting the raft to float. Its air-filled sacks were nearly half as dense as the straight acid; with this diluted stuff their buoyancy would be negligible.

He was almost wrong, as it turned out. The sea oozed up around the hill, snuffing the fires almost at a single blow, and for an instant blurred the picture transmitted from the robot's eyes as it covered the camp. Then the screens cleared, and showed the limp figures of the four natives on a structure that just barely scraped what had now become the bottom of the ocean. It moved, but only a few inches at a time; and Raeker gloomily sent the robot following along.

XI. ORGANIZATION; REVELATION; DECLARATION

NIGHTS - Tenebran nights, that is - were hard on the Drommian, Aminadabarlee. They were even harder on any men who had dealings with him while they lasted. Seeing people engaged in work that had no direct bearing on the rescue of his son, and watching them for two Earthly days at a stretch, was hard for him to bear, even though he knew perfectly well that nothing could be done while the agents on the ground were immobilized or actually unconscious. This made no difference to his emotions; somebody, or everybody, should be doing something, his glands told him. He was rapidly, and quite unavoidably, coming to regard human beings as the most cold-blooded and uncooperative race in the galaxy. This was in spite of the skilled efforts of Rich, who had plenty to keep him professionally busy.

So far the great nonhuman had not descended to physical violence, but more than one man was carefully keeping out of his way. These were the ones least familiar with Drommians - so far. Raeker had noted that the number was increasing.

Raeker himself wasn't worrying; he wasn't the sort. Besides, he was occupied enough to keep his mind off Dromm and its impulsive natives. The robot, fortunately, had had no fighting to do, since nothing in the form of animal life had approached the raft and its helpless pas* sengers, or had even been sighted by the carefully watching robot. This was a relief in one way, though Raeker was professionally disappointed. He had wanted to learn something of the creatures who were responsible for the loss of his students' herd a few nights before, and who could apparently live in a remarkably small oxygen concentration. Still, the four tied to the raft were fairly safe, though no one dared let them drift far from the robot; a constant watch was necessary.

As the night wore on, the vagrant currents which had been shifting raft and occupants became fewer, and so much weaker that they were no longer able to move the assembly, whose effective weight must have been only a few pounds. The man in control of the robot found it possible to leave the machine motionless for longer and longer periods; in fact, at one point Raeker almost went to sleep in the control chair. He was aroused from a doze by the shrill voice of the Drommian, however - "And Earthmen expect people to work with them!" in what even a man could recognize as a contemptuous tone - and did not repeat the slip. It didn't matter; the raft's passengers were drifting unharmed when day arrived. This period was the hardest, as far as standing guard was concerned; as the water began to boil back out of the sea, the latter's density increased, and the raft began to float. It was extremely fortunate that there were by then no currents at all; raft and passengers went straight up. Unfortunately, but somewhat naturally, it turned upside down as it went, so that for a couple of hours the robot operator had the annoyance of seeing the natives hanging from the underside of the floating platform while they very gradually led the surface of the ocean back toward the ground. They had drifted away from the hilltop during the night, and eventually wound up floating in a relatively small pool in one of the nearby hollows. When it finally became evident that the pool would shrink no farther, the robot had to take action.

Fortunately, the oleum was shallow - so shallow that the raft was supported more by the bodies under it than by its own buoyancy. Raeker guided the machine through the liquid, pushing the four unconscious natives ahead of it to the other side. The raft naturally came along, but eventually the rather untidy heap was dripping at the edge of the oleum pool, with the foundation members struggling gradually back to consciousness.

By this time the bathyscaphe was also out of the sea. Like the raft, it had wound up in a pool at the bottom of a valley; unlike it, there was no question of its floating. The pool was too shallow. As a result, Easy and her friend found themselves in their pressure-tight castle fully equipped with a moat, which effectively prevented Swift and his crew from reaching them.

For Swift was there. He turned up within an hour of the time the pool had finished shrinking, in spite of the considerable distance the bathyscaphe must have drifted during the night. It was out of sight of the sea, Easy reported; the wind that had been moving everything else inland had brought the ship along. It didn't bother her; she said that they were getting along splendidly with Swift, and didn't seem too worried when told about Nick's reverses of the night. Rich lost his temper for the first time when he learned that Raeker had carelessly told the child about the destruction of the camp, and didn't regain it until the girl's voice made it perfectly clear that the story hadn't affected her morale.

Raeker himself was thinking less about her than about his rescue operation, at the moment; that was why he had been so careless with his words. Nick and Betsey, Jim and Jane were all safe; the maps had remained attached to the raft, and so had most of the weapons. However, it was going to take a little while to find just where they were, short as the distance they had drifted probably was; and when they did find the camp site, it seemed rather unlikely that they would find much else. The herd would be gone, or nearly so; the wagon - who could tell? A similar period under an Earthly ocean would write it off completely, even in the off chance that it could be found. Here, there was no saying, but Raeker was not optimistic. Finding the site of last night's fire proved easier than expected. The wind proved to be a clue, when it finally occurred to someone - Jim, rather to Raeker's surprise. He and Jane, of course, had bucked it all the way back from their search areas, though they had not attached any meaning to it at the time; now it served to restore the "sense of direction" which for Tenebrans as for humans was a compound of memory and the understanding of elementary natural phenomena. Once they knew the direction of the sea, there was no more trouble; there was no question that they had drifted pretty straight inland. The wagon and the remains of the watch fires were found in an hour. Raeker was really startled to find it and its contents intact; the mere fact that the two-mile hurricane had changed from gas to scarcely denser liquid had made no difference to most of the solid objects in its path.

"I think we can save a little time," he said at length, when the status of the group's belongings had been determined. "We can go back to the sea now, carrying the boat with us. We'll leave the cart, with a written message for the others; they can either follow us or start moving camp, depending on what seems best at the tune they get back. We'll test out the boat, and search as far south along the coast as tune permits today."

"What do you mean by that?" asked Nick. "Do we search until dark, or until there's only enough time to get back here before dark?"

"Until nearly dark," Raeker replied promptly. "We'll go south until we decide it's far enough, and then go straight inland from wherever we are so as to get away from the ocean in time."

"Then the others had better move camp no matter what time they get back, and head south with the cart. We're going to have a food problem, and so are they, with the herd gone."

"Gone? I thought I saw quite a few, with Jim and Jane rounding them up."

"That's true, they're not all gone; but they're down to where we can't afford to eat any until a few more hatch. We couldn't even find scales of the others, this time."

"You couldn't? And I didn't see any creatures traveling around while you were in the sea, either. It seems to me that your missing cattle are more likely to have strayed than been stolen."

"That may be, but they're gone in any case, as far as we're concerned. If all four of us are heading for the sea right away to test this boat, we won't be able to look for them."

Raeker thought rapidly. Loss of the herd would be a serious blow to his community; remote-control education cannot, by itself, transform a group of people from nomadic hunters into a settled and organized culture with leisure time for intellectual activity. Without the herd Raeker's pupils would have to spend virtually all their time finding food. Still, they would live; and unless Easy and her companion were collected pretty soon they probably wouldn't. The question really, then, was not whether any could be spared from the cattle-hunt but whether one or two or all would be more useful in testing the boat and, if the test were successful, subsequently searching for the bathyscaphe from it. Certainly two people were less likely to sink the thing than four. On the other hand, four could presumably drive it faster - Raeker suddenly recalled that neither he nor Nick had given any thought to the method of propulsion the raft was to have. He supposed paddles or something of that nature would be about the only possible means; the thought of trying to teach Nick the art of sailing on a world where the winds were usually nonexistent and the nearest qualified teacher sixteen light years away seemed impractical. With muscle power as the drive agent, though, the more muscles the better.

"All of you will come to the sea. We'll consider the herd problem later. If the boat won't carry all of you, the extra ones can come back and hunt for cattle. This search is important."

"All right." Nick sounded more casual than he actually felt; all his life, as a result of Raeker's own teaching, he had felt that the safety of the herd was one of the most important considerations of all. If this search were still more so, it must really mean something to the Teacher; he wished he could feel that it meant as much to him. He didn't argue, but he wondered and worried.

The four of them were able to carry the boat easily enough, though bucking the wind made matters a little awkward - the wind was even stronger today, Nick decided. In a way, that was good; a last backward glance at the deserted remnants of the herd showed that a huge floater was being swept past them by the savage current and, in spite of all its efforts, could not beat its way back to the relatively helpless creatures. Nick pointed this out to his companions, and they all felt a little better. The two miles to the sea were covered fairly rapidly, and no formalities were wasted in testing the boat. It was carried out into waist-deep oleum and set down, and the four promptly climbed aboard. It supported them - just. The floats were completely submerged, and the framework virtually so. The difficulty was not one of keeping on the surface, but of keeping more or less level. The four were all of almost the same age, but they did differ slightly in weight. One side of the raft persisted in settling deeper whenever they stopped moving; each tune this happened they all, naturally, made a scramble for the rising portion, and each time they inevitably overcontrolled so that the raft rocked and tipped precariously first one way and then the other. It took several minutes and much misdirected action and speech before they learned the trick; then they took longer still to learn the use of the paddles Fagin had told them how to make. The robot itself was not too much use; if it stayed ashore its operators couldn't see things on the raft very clearly, and it it crawled into the sea to any point near the vessel it couldn't make itself heard - the boundary between oleum and air was sharp enough to reflect sound waves pretty completely. "Why do you have them looking at all?" Aminadabarlee asked acidly at this point. "The robot can travel along the shore as fast as they can paddle that ridiculous craft, and the bathyscaphe isn't at sea anyway. If you think those pupils are going to be of any use, why not have them walk with the machine?"

"Because, while all you say is true, the kids are inaccessible to the natives unless a boat is present. It doesn't seem likely that we'd save time by having Nick and his friends search on foot, and then have to go all the way back for the boat when they found the 'scaphe."

"I see," said the Drommian. Raeker cast a quick glance at him. The fellow was being unusually agreeable, all things considered; but the man had no time to ponder possible reasons. Nick and his companions were still too much in need of watching. He spoke over his shoulder, however, remembering Rich's injunction about being as courteous as possible to the big weasel. "There's one thing that might help a great deal, though. You've been talking to your son all along, just as Councillor Rich and I have been talking to Easy; do you suppose he'd be the better for something constructive to do down there?"

"What?"

"Well, if he's as good at picking up languages as Easy was supposed to be, maybe he'd do a better job than she at rinding something out from the cave dwellers. Swift quite obviously knows where both our camp and the bathyscaphe are; it would be most helpful if someone could worm a set of directions out of him for getting from the one to the other."

The Drommian's face was unreadable to Raeker, but his voice suggested what from him was high approval.

"That's the first sensible remark I've heard from a human being in the last five weeks," he said. "I'll explain to Aminadorneldo what to do. There's no point in expecting the human girl to do it herself, or to help him." The diplomat must be credited with what for him was the ultimate in tact, courtesy, and selfcontrol - he had restrained himself from remarking that no human being could be expected to be helpful in a situation calling for intelligence.
