„We are uncomfortable when the sea freezes, but we can stand it — if it does not get too much colder. Why?”

„It’s just possible you may have to crowd the northern icecap pretty closely. We’ll see, though.” The Flyer riffled through the stack of prints, still taller than Barlennan was long, and eventually extracted a thin sheaf. „One of these. ” His voice trailed off for a few moments. „Here we are. This was taken from the inner edge of the ring, Barl, over six hundred miles up, with a narrow-angle telephoto lens. You can see the main shore line, and the big bay, and here, on the south side of the big one, the little bay where the Bree

is beached. This was taken before this station was built — though it wouldn’t show anyway.

„Now let’s start assembling again. The sheet east of this.” He trailed off again, and the Mesklinite watched in fascination as a readable map of the lands he had not yet reached took form below him. For a time it seemed they were to be disappointed, for the shore line gradually curved northward as Lackland had thought; indeed, some twelve hundred miles to the west and four or five hundred north, the ocean seemed to come to an end — the coast curved westward again. A vast river emptied into it at this point, and with some hope at first that this might be a strait leading to the eastern sea, Lackland began fitting the pictures that covered the upper reaches of the mighty stream. He was quickly disabused of this idea, by the discovery of an extensive series of rapids some two hundred and fifty miles upstream; east of these, the great river dwindled rapidly. Numerous smaller streams emptied into it; apparently it was the main artery for the drainage system of a vast area of the planet. Interested by the speed with which it broke up into smaller rivers, Lackland continued building the map eastward, watched with interest by Barlennan.

The main stream, as far as it could be distinguished, had shifted direction slightly, flowing from a more southerly direction. Carrying the mosaic of pictures in — this direction, they j found a range of very fair-sized mountains, and the Earthman looked up with a rueful shake of his head. Barlennan had come to understand the meaning of this gesture.

„Do not stop yet!” the captain expostulated. „There is a similar range along the center of my country, which is a fairly narrow peninsula. At least build the picture far enough to determine how the streams flow on the other side of the mountains.” Lackland, though not optimistic — he recalled the South American continent on his own planet too clearly to assume any symmetry of the sort the Mesklinite seemed to expect — complied with the native’s suggestion. The range proved to be fairly narrow, extending roughly east-northeast by west-southwest; and rather to the man’s surprise the numerous „water” courses on the opposite side began very quickly to show a tendency to come together in one vast river. This ran roughly parallel with the range for mile after mile, broadening as it went, and hope began to grow once more. It reached a climax five hundred miles downstream, when what was now a vast estuary merged indistinguishably with the „waters” of the eastern ocean. Working feverishly, scarcely stopping for food or even the rest he so badly needed in Mesklin’s savage gravity, Lackland worked on; and eventually the floor of the room was covered by a new map — a rectangle representing some two thousand miles in an east-west line and half as far in the other dimension. The great bay and tiny cove where the Bree was beached showed clearly at its western end; much pf the other was occupied by the featureless surface of the eastern sea. Between lay the land barrier.

It was narrow; at its narrowest, some five hundred miles north of the equator, it was a scant eight hundred miles from coast to coast, and this distance was lessened considerably if one measured from the highest usable points of the principal rivers. Perhaps three hundred miles, part of it over a mountain range, was all that lay between the Bree and a relatively easy path to the distant goal of the Earthmen’s efforts. Three hundred miles; a mere step, as distances on Mesklin went.

Unfortunately, it was decidedly more than a step to a Mesklinite sailor. The Bree was still in the wrong ocean; Lackland, after staring silently for many minutes at the mosaic about him, said as much to his tiny companion. He expected no answer, or at most a dispirited agreement; his statement was self-evidently true — but the native fooled him.

„Not if you have more of the metal on which we brought you and the meat back!” was Barlennan’s instantaneous reply.

VI: THE SLED

For another long moment Lackland stared out the window into the sailor’s eyes, while the implications of the little creature’s remark sank into his mind; then he stiffened into something as closely approaching an alert attitude as the gravity permitted.

„You mean you would be willing to tow the Bree overland on a sledge, as you did me?”

„Not exactly. The ship outweighs us very much, and we would have the same trouble with traction that we did before. What I had in mind was your towing, with another tank.”

„I see. I — see. It would certainly be possible, unless we hit terrain that the tank couldn’t pass. But would you and your crew be willing to” make such a journey? Would the extra trouble and distance from your home be repaid by the little we could do for you?”

Barlennan extended his pincers in a smile.

„It would be much better than what we originally planned. There are trading goods that come from the shores of the eastern ocean to our country, by the long caravan routes overland; by the time they reach the ports on our own sea, they are already fabulously expensive, and an honest trader cannot make a decent profit from them. This way, if I picked them up directly — well, it would be certainly very worth while indeed, for me. Of course, you would have to promise to bring us back across tfe isthmus when we returned.”

„That would certainly be fair enough, Barl; I’m sure my people will gladly agree to it. But how about the land travel itself? This is country you know nothing about, as you have said; might not your crew be afraid of unknown land, and high hills over them, and maybe animals larger than can possibly grow in yotir part of the world?”

„We have faced dangers before,” the Mesklinite replied. „I was able to get used to high places — even the top of your tank. As for animals, the Bree is armed with fire, and none that walk on land could be as large as some that swim the oceans.”

„That’s true enough, Barl. Very well. I was not trying to discourage you, goodness knows; but I wanted to be sure you had thought the matter over before you embarked on such a project. It’s hardly one that can be backed out of in the middle.”

„That I can readily understand, but you need not fear, Charles. I must return to the ship now; the clouds are gathering again. I will tell the crew what we are going to do; and lest the thoughts of fear should come to any of them, I will remind them that the profits of the voyage will be shared according to rank. There is no member of that crew who would put fear in the way of wealth.”

„And you?” Lackland chuckled as he asked the question. „Oh, I’m not afraid.” The Mesklinite vanished into the night as he spoke the words, and Lackland was never sure just how he meant them.

Rosten, when he heard the new plan, made a number of caustic remarks to the effect that Lackland could certainly be counted on for ideas that would give him use of a tank.

„It seems as though it should work, though,” he admitted grudgingly. „Just what sort of sled are we supposed to build for this ocean liner of your friend’s? How big is it, again?”
