Mission of Gravity

by Clement Hal

They made the cataract in a single lap of about twenty days. Both natives and Earthman heard it long before they arrived, at first a vague trembling in the air that gradually rose through a muted thunder to a roar that put even the Mesklinite vocal equipment to shame. It was day when they came in sight of it, and Lackland stopped involuntarily as they did so. The river was half a mile wide where it reached the brink, and smooth as glass — no rocks or other irregularities appeared to exist in its bed. It simply curled over the edge and spilled downward. The fall had eroded its way for a full mile back from the cliff line; and they had a splendid view of the gorge. The ripple marks gave no clue to the liquid’s speed of fall, but the violence with which the spray erupted from the bottom did. Even in this gravity and atmosphere a permanent cloud of mist hid the lower half of the curved sheet, thinning gradually away from its foot to reveal the roiled, eddied surface of the lower river. There was no wind except that created by the fall itself, and the stream grew rapidly calmer as it moved smoothly away toward the ocean.

The crew of the Bree had gone overboard the moment the tank stopped; and the way they were strung out along the rim of the gorge indicated that there would not be much morale difficulty during the descent. Now Barlennan called them back to the ship, and work commenced at once. Lackland relaxed once more while cordage was dragged forth and a plumb line dropped over the edge to secure a more precise measure of the cliff’s height. Some of the sailors began securing all loose gear about the rafts, though preparations for the original journey had left little to do in this respect; others reached down between the rafts and began unfastening the lashings which held them together and checking at the same time the buffers that held them safely apart. They were fast workers, and raft after raft was dragged away from the main body of the ship.

Barlennan and his first mate, once this work was well under way, went over to the edge to determine the best place for the lowering operation. The gorge itself was rejected at once; the river within its walls was too rough, even if they had wanted to do their reassembling while afloat. It turned out, however, that almost any point on the cliff face would be suitable, so the officers quickly chose one as close as possible to the mouth of the gorge. The reassembled ship or its separate parts would have to be dragged to the river without the tank’s help, and there was no point in making the journey any longer than necessary.

A scaffold of masts was arranged at the edge to give a point of suspension, far enough out to prevent rope friction, though the masts were not long enough to hold a raft completely away from the cliff face; a block and tackle, which Lackland observed with interest, was attached to the scaffold, and the first raft dragged into position. It was adjusted in a rope sling that would carry it horizontally, the main cable attached to the sung and hitched around a tree, several sailors seized the cable, and the raft was pushed over the edge.

Everything held up, but Dondragmer and his captain inspected each part very, very carefully before the mate and one of the crew crawled aboard the platform that hung somewhat slanted against thevrock an inch or so below the edge. For a moment after they had gone aboard everyone watched expectantly; but again nothing happened, and Dondragmer finally gave the signal to lower away. All the crew members who were not on the cable rushed to the edge to watch the descent. Lackland would have liked to watch it himself, but had no intention of venturing either the tank or his armored person close enough to do so. Beside ‘his own uneasiness at the height, the sight of the cordage the Mesklinites were using made him unhappy; it looked as though an Earthly clerk would scorn it for tying a two-pound bag of sugar.

An excited hooting and general withdrawal from the edge indicated the safe arrival of the first raft, and Lackland blinked as the sailors proceeded to stack several more on top of each other while the cable was being drawn up. Apparently no more time than could be helped was to be wasted. Confident as he was in Barlennan’s judgment, the Earthman suddenly decided he wanted to watch the stack of rafts make the descent. He was on the point of donning his armor when he remembered that it was not necessary; he relaxed again, called Barlennan, and asked him to arrange one or more of the little communicators so that their “eyes” could cover the desired activity. The captain complied immediately, having a sailor lash one of the sets to the scaffold so that it looked almost straight down and placing another on top of the pile of rafts which had just been secured in their rope sling. Lackland switched from one to the other as the operation proceeded. The first was a trifle more disconcerting than he had expected, since the supporting cable was visible for only a few feet from the pickup lens and the load seemed to be floating down without support; the other gave him a view of the cliff face that would

undoubtedly have been highly interesting to a geologist. With the descent half completed, it occurred to him to call Toorey to invite the interested parties to watch. The geology department responded and commented freely during the rest of the process.

Load after load went down, with little variety to make the operation more interesting. Toward the end a longer cable was installed and the lowering was done from below, since the greater part of the brew had now descended; and Lackland had a suspicion of the reason when Barlennan finally turned away from the scene of action and leaped toward the tank. The radio which had been used from that position was permanently mounted, and had not been taken down with the others.

“We have only about two more loads, Charles,” the captain opened. “There will be a sh’ght problem in connection with the last one. We’d like to keep all our gear if possible, which means dismantling and sending down the masts used for our lowering tackle. We don’t want to throw them down because we’re not sure they’d take it — the soil below is very rocky. Would you be willing to get into your armor and lower the final load by hand? I will arrange for it to consist of one raft, those few masts and the associated tackle, and myself.” Lackland was startled by the last item.

“You mean you would trust yourself to my strength, knowing that I’m already under three and a half times my normal gravity and will have the weight of my armor as well?”
