"It was a sandstorm," said Redfeather coldly. "Probably there was a sunspot flare-up. We don't know. But the pre-colonization survey spoke of sandstorms. The survey team even made estimates of sandfall in various places as so many inches per year. Here all storms drop sand instead of rain. But there must have been a sunspot flare because this storm blew for"--his voice went flat and deliberate because it was stating the unbelievable--"for two months. We did not see the sun in all that time. And we couldn't work, naturally. The sand would flay a man's skin off his body in minutes. So we waited it out. "When it ended, there was this sand plateau where the survey had ordered the landing grid to be built. The grid was under it. It is under it. The top of eighteen hundred feet of steel is still buried two hundred feet down in the sand you see. Our unfabricated building-steel is piled ready for erection--under two thousand feet of sand. Without anything but stored power it is hardly practical"--Redfeather's tone was sardonic--"for us to try to dig it out. There are hundreds of millions of tons of stuff to be moved. If we could get the sand away, we could finish the grid. If we could finish the grid, we'd have power enough to get the sand away--in a few years, and if we could replace the machinery that wore out handling it. And if there wasn't another sandstorm." He paused. Bordman took deep breaths of the cooler air. He could think more clearly. "If you will accept photographs," said Redfeather politely, "you can check that we actually did the work." * * * * * Bordman saw the implications. The colony had been formed of Amerinds for the steel work and Africans for the labor the Amerinds were congenitally averse to--the handling of complex mining-machinery underground and the control of modern high-speed smelting operations. Both races could endure this climate and work in it--provided that they had cooled sleeping quarters. But they had to have power. Power not only to work with, but to live by. The air-cooling machinery that made sleep possible also condensed from the cooled air the minute trace of water vapor it contained and that they needed for drink. But without power they would thirst. Without the landing grid and the power it took from the ionosphere, they could not receive supplies from the rest of the universe. So they would starve.
