Mission of Gravity by Hal Clement

crew. When that was done Lackland asked:
    „Have you ever heard of people living this close to the Rim, Barl? Would they be at all likely to be known to you, or even speak the same language?”
    „I doubt it very much. My people become very uncomfortable, as you know, north of what you once called the hundred-G line.’ I know several languages, but I can’t see any likelihood of finding one of them spoken here.”
    „Then what shall we do? Sneak around this town, or go through it on the chance its people are not belligerent? I’d like to see it more closely, I admit, but we have an important job to do and I don’t want to risk its chances of success. You at least know your race better than I possibly can; how do you think they’ll react to us?”
    „There’s no one rule, there. They may be frightened out of their wits at your tank, or my riding on it — though they might not have normal instincts about height, here at the Rim. We’ve met lots of strange people in our wanderings, and sometimes we’ve been able to trade and sometimes we’ve had to fight. In general, I’d say if we kept weapons out of sight and trade goods in evidence, they would at least investigate before getting violent. I’d like to go down. Will the sled fit through the bottom of those channels, do you think?”
    Lackland paused. „I hadn’t thought of that,” he admitted after a moment. „I’d want to measure them more carefully first. Maybe it would be best if the tank went down alone first, with you and anyone else who cared for the ride traveling on top. That way we might look more peaceful, too — they must have seen the weapons your men were carrying, and if we leave them behind — ”
    „They didn’t see any weapons unless their eyes are a great deal better than ours,” pointed out Barlennan. „However, I agree that we’d better g& down first and measure — or better yet, tow the ship around the valley first and go down afterward as a side trip; I see no need to risk her in those narrow channels.”
    „That’s a thought. Yes, I guess it would be the best idea, at that. Will you tell your crew what we’ve decided, and ask if any of them want to come down with us afterward?”
    Barlennan agreed, and returned to the Bree for the purpose — he could speak in a lower tone there, although he did not feel that there was any real danger of being overheard and understood.
    The crew in general accepted the advisability of taking the ship around rather than through the city, but from that point on there was a little difficulty. All of them wanted to see the town, but none would even consider riding on the tank, often as they had seen their captain do so without harm. Don-dragmer broke the deadlock by suggesting that the crew, except for those left to guard the Bree, follow the tank into the town; there was no need to ride, since all could now keep up the speed the vehicle had been using up to this time.
    The few minutes this discussion consumed brought the sun once more above the horizon; and at Barlennan’s signal the Earthman swung the tank ninety degrees and started around the rim of the valley just below its coping of boulders. He had taken a look at the city before starting, and saw no sign of life; but as the tank and its tow swung into motion heads appeared once more at the small doors-many more of them, this time. Lackland was able to concentrate on his driving, sure now that — their owners would still be there when he was free to examine them more closely. He attended to his job for the few days required to get the sled around to the far side of the valley; then the tow cable was cast off, and the nose of the tank pointed downhill.
    Practically no steering was required; the vehicle tended to follow the course of the first channel it met, and went by itself toward the space which, Lackland had come to regard-wholly without justification — as the market place of the town. Approximately half of the Bree’s crew
