“Shall we start right away, Captain?”
“No. We will wait here until we know that Dondragmer is back to the ship. If he runs into trouble we will have to use some other plan, which would probably require us to go back down ourselves; in that case it would be a waste of time and effort to have traveled any distance, and would cost time that might be valuable in getting back.” Meanwhile, Dondragmer and his group reached the slope without difficulty. They stopped just long enough for the mate to make sure that all harnesses were securely fastened at regular intervals along the rope he had brought; then he attached his own at the rear, and gave the order to start down. The rope proved a good idea; it was harder even for the many feet of the Mesklinites to keep their traction while heading downward than it had been on the way up. The wind showed no tendency to pick anyone up this time, since they had no packs on which it could get a grip, but the going was still awkward. As before, everyone lost all track of time, and all were correspondingly relieved when the way opened ahead and they were able to swing to the left out of the wind’s path. They still found themselves looking down, of course, which was extremely hard on Mesklinite nerves; but the worst of the descent was over. Only three or four days were consumed in getting down the rest of the way and aboard the still waiting Bree. The sailors with the ship had seen them coming long enough in advance to develop a number of theories, mostly tragic in tone, concerning the fate of the rest of the party. They were quickly reassured, and the mate reported his arrival to the men on Toorey so that they could relay the information to Barlennan on the plateau. Then the ship was dragged back to the river — a real task, with a quarter of the crew missing and the full power of polar gravity to plaster the rafts to the beach, but it was finally accomplished. Twice the vessel hung up on small pebbles that had not quite stopped her going the other way; the differential hoist was put to effective use. With the
Bree once more afloat, Dondragmer spent much of the time on the downstream trip examining the hoist. He already knew its principles of construction well enough to have made one without help; but he could not quite figure out just why it worked. Several Earthmen watched him with amusement, but none was discourteous enough to show the fact — and none dreamed of spoiling the Mesklinite’s chance of solving the problem by himself. Even Lackland, fond as he was of Barlennan, had long since come to the conclusion that the mate was considerably his captain’s superior in general intelligence, and rather expected that he would be regaling them with a sound mechanical explanation before the Bree reached her former stopping place; but he was wrong. The position of the grounded rocket was known with great accuracy; the uncertainty was less than half a dozen miles. Its telemetering transmitters — not all the instruments had been of permanent-record type — had continued to operate for more than an Earth year after the failure to answer takeoff signals; in that time an astronomical number of fixes had been taken on the location of the transmitters. Mesklin’s atmosphere did not interfere appreciably with radio. The Bree could also be located by radio, as could Barlennan’s party; it would be the job of the Earthmen to guide the two groups together and, eventually, lead them to the grounded research projectile. The difficulty was in obtaining fixes from Toorey; all three targets were on the “edge” of the disc as seen from the moon. Still worse, the shape of the planet meant that a tiny error in the determination of signal direction could mean a discrepancy of some thousands of miles on the world’s surface; the line of the antenna just about grazed the flattest part of the planet. To remedy this, the rocket that had photographed the planet so much was launched once more, and set into a circular orbit that crossed the poles at regular intervals. From this orbit, once it was accurately set up, fixes could be taken with sufficient precision on the tiny transmitters that the Mesklinites were carrying with them. The problem became even simpler when Dondragmer finally brought the Bree to its former halting place and established a camp. There was now a fixed transmitter on the planet, and this made it possible to tell Barlennan how much farther he had to go within a minute or two of any time he chose to ask. The trip settled down to routine once more — from above.
