“Would it not be advisable to have the Flyer’s friends far above learn for us just how far this cliff extends to either side? It may be possible to descend an easier slope without too great a detour. It should not be hard for them to make new maps, if this cliff was missed on the first.” Barlennan translated this remark, which was made in the mate’s own language. Lackland raised his eyebrows.
“Your friend may as well speak English himself, Barl — he appears to know enough to understand our last conversation. Or do you have some means of communicating it to him that I don’t know about?”
Barlennan whirled on his mate, startled and, after a moment, confused. He had not reported the conversation to Dondragmer; evidently the Flyer was right — his mate had learned some English. Unfortunately, however, the second guess had also some truth; Barlennan had long been sure that many of the sounds his vocal apparatus could produce were not audible to the Earthman, though he could not guess at the reason. For several seconds he was confused, trying to decide whether it would be better to reveal Dondragmer’s ability, the secret of their communication, both together, or, if he could talk fast enough, neither. Barlennan did the best he could.
“Apparently Dondragmer is sharper than I realized. Is it true that you have learned some of the Flyer’s language, Don?” This he asked in English, and in a pitch that Lackland could hear. In the shriller tones that his own language employed so much he added, “Tell the truth — I want to cover up as long as possible the fact that we can talk without his hearing. Answer in his own language, if you can.” The mate obeyed, though not even his captain could have guessed at his thoughts.
“I have learned much of your language, Charles Lackland. I did not realize you would object.”
“I don’t mind at all, Don; I am very pleased and, I admit, surprised. I would gladly have taught you as well as Barl if you had come to my station. Since you have learned on your own — I suppose from comparing our conversations and your captain’s resultant activities — please enter our discussion. The suggestion you made a moment ago was sound; I will call the Toorey station at once.”
The operator on the moon answered immediately, since a constant guard was now being maintained on the tank’s main transmitter frequency through several relay stations drifting in Mesklin’s outer ring. He indicated understanding of the problem, and promised that a survey would be made as quickly as possible.
“As quickly as possible,” however, meant quite a number of Mesklin’s days; and while waiting the trio endeavored to formulate other plans in case the cliff could not be rounded within a reasonable distance.
One or two of the sailors expressed a willingness to jump down the cliff, to Barlennan’s anxiety — he felt that the natural fear of height should not be replaced with complete contempt, even though the entire crew now shared his willingness to climb and jump. Lackland was called upon to help disuade these foolhardy individuals, which he managed to do by computing that the sixty-foot drop of the cliff was about equal to a one-foot fall at the latitude of their home country. This revived enough memory of childhood experience to put a stop to the idea. The captain, thinking over this event afterward, realized that by his own lifelong standards he had a crew composed entirely of lunatics, with himself well to the front in degree of aberration; but he was fairly sure that this particular form of insanity was going to be useful.
Ideas more practical than these were not forthcoming for some time; and Lackland took the opportunity to catch up on his sleep, which he badly needed. He had had two long sessions in his bunk, interrupted by a hearty meal, when the report of the surveying rocket came in. It was brief and discouraging. The cliff ran into the sea some six hundred miles northeast of their present location, almost exactly on the equator. In the opposite’ direction it ran for some twelve hundred miles, growing very gradually lower, and disappearing completely at about the five-gravity latitude. It was not perfectly straight, showing a deep bend away from the ocean at one point; the tank had struck it at this point. Two rivers fell over its edge within the limits of the bay, and the tank was neatly caught between them, since in the interests of common sanity the Bree could never be towed across either without first going many miles upstream from the tremendous cataracts. One of the falls was about thirty miles away, almost due south; the other approximately a hundred miles distant to the north and east around the curve of the cliff. The rocket had not, of course, been able to examine the entire stretch of escarpment in complete detail from the altitude it had had to maintain, but the interpreter was very doubtful that the tank could scale it at any point. The best bet, however, would be near one of the falls, where erosion was visible and might conceivably have created negotiable paths.
“How in blazes can a cliff like this form?” Lackland asked resentfully when he had heard all this. “Eighteen hundred miles of ridge just high enough to be a nuisance, and we have to run right into it. I bet it’s the only thing of its kind on the planet.”
“Don’t bet too much,” the surveyor retorted. “The physiography boys just nodded in pleasure when I told them about it. One of them said he was surprised you hadn’t hit one earlier; then another piped up and said actually you’d expect most of them farther from the equator, so it wasn’t surprising at all. They were still at it when I left them. I guess you’re lucky that your small friend is going to do most of the traveling for you.”
“That’s a thought.” Lackland paused as another idea struck him. “If these faults are so common, you might tell me whether there are any more Jbetween here and the sea. Will you have to run another survey?”
“No. I saw the geologists before I started on this one, and looked. If you can, get down this step, you’re all right-in fact, you could launch your friend’s ship in the river at the foot and he could make it alone. Your only remaining problem is to get that sailboat hoisted over the edge.”
“To get — hmm. I know you meant that figuratively, Hank, but you may have something there. Thanks for everything; I may want to talk to you later.” Lackland turned away from the set and lay back on his bunk, thinking furiously. He had never seen the Bree afloat; she had been beached before he encountered Barlennan, and on the recent occasions when he had towed her across rivers he had himself been below the surface most of the time in the tank. Therefore he did not know how high the vessel floated. Still, to float at all on an ocean of liquid methane she must be extremely light, since methane is less than half as dense as water. Also she was not hollow — did not float, that is, by virtue of a large central air space which lowered her average density, as does a. steel ship on Earth. The “wood” of which the Bree was made was light enough to float on methane and support the ship’s crew and a substantial cargo as well.
An individual raft, therefore, could not weigh more than a few ounces — perhaps a couple of pounds, on this world at this point. At that rate, Lackland himself could stand on the edge of the cliff and let down several rafts at a time; any two sailors could probably lift the ship bodily, if they could be persuaded to get under it. Lackland himself had no rope or cable other than what he was using to tow the sled; but that was one commodity of which the Bree herself had an ample supply. The sailors should certainly be able to rig hoisting gear that would take care of the situation — or could they? On Earth it would be elementary seamanship; on Mesklin, with these startling but understandable prejudices against lifting and jumping and throwing and everything else involving any height, the situation might be different. Well, Bar-lennan’s sailors could at least tie knots, and the idea of towing should not be too strange to them now; so undoubtedly the matter could be straightened out. The real, final problem was whether or not the sailors would object to being lowered over the cliff along with their ship. Some men might have laid that question aside as strictly a problem for the ship’s captain, but Lackland more than suspected that he would have to contribute to its solution.
