determine whether human beings would want to live on it—whether, in fact, they themselves would want to, because, if so, they had the option of becoming the first settlers. That was the way the system worked and, in the main, it worked well enough. [Pg 81] After less than two weeks, this scout team had beamed back to Earth the message that the planet was suitable for colonization, so suitable that they would like to give it the name of Elysium, if there was no objection. There would be none, Earth had replied, so long as the pioneers bore in mind the fact that six other planets had previously been given that name, and a human colony currently existed on only one of those. No need to worry about a conflict of nomenclature, however, because the name of that other planet Elysium had subsequently been changed by unanimous vote of settlers to Hades. After this somewhat sinister piece of information, Earth had added the more cheerful news that the wives and families of the scouts would soon be on their way, bringing with them the tools and implements necessary to transform the wilderness of the frontier into another Earth. In the meantime, the men were to set up the packaged buildings with which all scout ships were equipped, so that when the women came, homes would be ready for them. The men set to work and, before the month was out, they discovered that Elysium was neither a wilderness nor a frontier. It was populated by an intelligent race which had developed its culture to the limit of its physical abilities—actually well beyond the limit of what the astounded Terrestrials could have conceived its physical abilities to be—then, owing to unavoidable disaster, had started to die out. The remaining natives were perspicacious enough to see in the Terrestrials' coming not a threat but a last hope of revivifying their own moribund species. Accordingly, the Earthmen were encouraged to go ahead building on the sites originally selected, the only ban being on the type of construction materials used—and a perfectly reasonable one under the circumstances. James had built his cottage near the largest, handsomest tree in the area allotted to him; since there were no hostile life-forms, there was no need for a closely knit community. Everyone who had seen it agreed that his house was the most attractive one of all, for, although it was only a standard prefab, he had used taste and ingenuity to make it a[Pg 82] little different from the
