At long last, fully twelve hundred miles from where the Bree had wintered and some three hundred south of the equator, with Lackland bowing under an additional half gravity, the streams began to bear definitely in the general direction of their travel. Both Lackland and Barle
IX: OVER THE EDGE
For long moments nothing was said. Both Lackland and Barle
„How could it have been there?” Barle
„It should, Barl, and I can think of only one reason it escaped us. Each picture, you recall, covered many square miles; one alone would include all the land we can see from here, and much more. The picture that does cover this area must have been made between sunrise and noon, when there would have been no shadow.”
„Then this cliff does not extend past the boundary of that one picture?”
„Possibly; or, just as possibly, it chanced that two or three adjacent shots were all made in the morning — I don’t know just what course ‘the photo rocket flew. If, as I should imagine, it went east and west, it wouldn’t be too great a coincidence for it to pass the cliff several times ru
„Still, there’s little point in going through that question. The real problem, since the cliff obviously does exist, is how to continue our journey.” That question produced another silence, which lasted for some time. It was broken, to the surprise of at least two people, by the first mate.
„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.” Barle
„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?”
Barle
„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 Barle
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.”
