Mission of Gravity

The sailor climbed back into the Bree, explaining what had happened as he did so. All the crew whose duties did not keep them elsewhere rushed to the stern, and presently the rope was hauled in with the swamped canoe at the end of it. With some effort, the canoe and such of its load as had been adequately lashed down were hauled aboard, and one of the sets turned to view it. The object was not very informative; the tremendous resilience of the wood had resulted in its recovering completely even from this flattening, and the canoe had resumed its original shape, still without leaks. This last fact was established after it had once more been unloaded.

Lackland, looking it over, shook his head and offered no explanation. „Tell me just what happened — what everyone who saw anything at all did see.”

The Mesklinites complied, Barle

„Good Earth!” Lacklaiid muttered, half aloud. „What’s the use of a high school education if you can’t recall it when needed later on? Pressure in a liquid corresponds to the weight of liquid above the point in question — and even methane under a couple of hundred gravities weighs a good deal per vertical inch. That wood’s not much thicker than paper, either; a wonder it held so long.” Barle

„I gather you now know what happened,” he said. „Could you please make it clear to us?”

Lackland made an honest effort, but was only partly successful. The concept of pressure, in a quantitative sense, defeats a certain number of students in every high school class.

The main point, of course, was that any floating object had to have some part of itself under the surface, and that sooner or later that part was going to be crushed if it was hollow. He avoided Dondragmer’s eye as this conclusion was reached in his conversation with Lackland, and was not comforted when the mate pointed out that this was undoubtedly where he had betrayed his falsehood when talking to Reejaaren. Hollow ships used by his own people, indeed! The islanders must have learned the futility of that in the far south long since.

The gear that had been in the canoe was stowed on deck, and the voyage continued. Barle

Time passed, as it had before, first hundreds and then thousands of days. To the Mesklinites, long-lived by nature, its passage meant little; to the Earthmen the voyage gradually became a thing of boredom, part of the regular routine of life. They watched and talked to the captain as the line on the globe slowly lengthened; measured and computed to determine his position and best course when he asked them to; taught English to or tried to learn a Mesklinite language from sailors who sometimes also grew bored; in short, waited, worked where possible, and killed time as four Earthly months — nine thousand four hundred and some odd Mesklinite days — passed. Gravity increased from the hundred and ninety or so at the latitude where the canoe had sunk to four hundred, and then to six, and then further, as indicated by the wooden spring balance that was the Bree’s latitude gauge. The days grew longer and the nights shorter until at last the sun rode completely around the sky without touching the horizon, though it dipped toward it in the south. The sun itself seemed shrunken to the men who had grown used to it during the brief time of Mesklin’s perihelion passage. The horizon, seen from the Bree’s deck through the vision sets, was above the ship all around, as Barle

And they were dashed, as they had been for a moment months before when Lackland’s tank reached the end of its journey. The reason was much the same; but this time the Bree and its crew were at the bottom of a cliff, not the top. The cliff itself was three hundred feet high, not sixty; and in nearly seven hundred gravities climbing, jumping and other rapid means of travel which had been so freely indulged at the distant Rim were utter impossibilities for the powerful little monsters who ma

The rocket was fifty miles away in horizontal distance; in vertical, it was the equivalent, fot a human being, of a climb of nearly thirty-five — up a sheer rock wall.

XV: HIGH GROUND

The change of mind that had so affected the Bree’s crew was not temporary; the unreasoning, conditioned fear of height that had grown with them from birth was gone. They Still, however, had normal reasoning power; and in this part of their planet a fall of as much as half a body’s length was nearly certain to be fatal even to their tough organisms. Changed as they were, most of them felt uneasy as they moored the Bree to the riverbank only a few rods from the towering cliff that barred them from the grounded rocket.

The Earthmen, watching in silence, tried futilely to think of a way up the barrier. No rocket that the expedition possessed could have lifted itself against even a fraction of Mesklin’s polar gravity; the only one that had ever been built able to do so was already aground on the planet. Even had the craft been capable, no human or qualified non-human pilot could have lived in the neighborhood; the only beings able to do that could no more be taught to fly a rocket than a Bushman snatched straight from the jungle.

„The journey simply isn’t as nearly over as we thought.” Rosten, called to the screen room, analyzed the situation rapidly. „There should be some way to the plateau or farther slope whichever is present — of that cliff. I’ll admit there seems to be no way Barle

„That is true,” the Mesklinite replied. „There are, however, a number of difficulties. It is already getting harder to procure food from the river; we are very far from the sea. Also, we have no longer any idea of how far we may have to travel, and that makes pla
