 Why is Jones a change in the pricing structure for supply runs?
[Transcriber's Note: This etext was produced from Astounding Science Fiction June 1959. Like when there's no use trying—when it's time to give up because it's hopeless.... The light from the star that died when the meteor was created fell on Earth before the first lungfish ventured from the sea. It drilled a small, neat hole through the casing of the steam turbine, and volitized upon striking the blades. Portions of the turbine also volitized; idling at eight thousand RPM, it became unstable. The shaft tried to tie itself into a knot, and the blades, damaged and undamaged were spit through the casing. It was two days to sunrise, where Evans stood. It was just before sunset on a spring evening in September in Sydney. The shadow line between day and night could be seen from the Moon to be drifting across Australia. Evans, who had no watch, thought of the time as a quarter after Australia. Evans was a prospector, and like all prospectors, a sort of jackknife geologist, selenologist, rather. The rest was promissory notes and grubstake shares. When he was broke, which was usually, he used his tractor to haul uranium ore and metallic sodium from the mines at Potter's dike to Williamson Town, where the rockets landed. Once he followed a stampede to Yellow Crater, where he thought for a while that he had a fortune in chromium. The chromite petered out in a month and a half, and he was lucky to break even. Evans was due back at Williamson Town at about sunset, that is, in about sixteen days. His drinking water—kept separate from the water in the reactor—might conceivably last just as long. But his oxygen was too carefully measured; there was a four-day reserve. Four days reserve—plus one is five—plus sixteen days normal supply equals twenty-one days to live. "Well, man, 'tis a fine spot you're in now," he told himself.
 It would allow more necessary supplies to reach Earth
 He thinks it would save time in writing contracts  He thinks he can make a bigger profit if he has more control  It would allow more necessary supplies to reach Earth  He wants to be able to carry more expensive supplies
