They wanted to go back to the lowlands. It was profitable, to be sure. But it was even more of a satisfaction to hunt and kill the monsters that had hunted and killed men for so long. It felt good, too, to find other humans and bring them out to sunshine. So nowadays the forgotten planet has ceased to be forgotten. It is hardly necessary to name it, because its name is known through all the Galaxy. Its population is not large, so far, but it is an interesting place to live in. In the popular mind, it is the most glamorous of all possible worlds,--and for easily understandable reasons. The inhabitants of its capital city wear moth-fur garments and butterfly-wing cloaks for the benefit of their fellows in the lowlands. There is no day but fliers take off and dive down into the mists. When human hunters are in the lowlands, they dress as the lowlanders they used to be, so that lowlanders who may spy them will be sure that they are men, and friends, and come to them to be raised to proper dignity above the insects. It is not unusual for a man to be brought up to sunshine, and have his session with the educator, and be flying his own assigned atmosphere-flier within a week, diving back above what used to be the place where he was hunted, but where he has become the hunter. It is a very pleasant arrangement. The search for more humans in the lowlands is a prosperous business, even when it is unsuccessful. The wings of white Morpho butterflies bring the highest prices, but even a common swallow-tail is riches, and the fur of caterpillars--duly processed--goes into the holds of the planet-owned space-line ships with the care given elsewhere to platinum and diamonds. And also it is good sport. The planet is a sportsman's paradise. There are not too many visitors. Nobody may go hunting without an experienced host. And off-planet sportsmen tend to feel somewhat queasy after a session as guest of the folk who have made Burl their planet-president. Visitors are not so much alarmed at fighting flying beetles in mid-air, even though the beetles may compare with the hunters' craft in size and are terrifically tenacious of life. The thing that appalls strangers is the insistence of Burl's fellow-citizens--no longer only tribesmen--upon fighting spiders on the ground. With their memories, they like it that way. It's more satisfactory. Not long ago the Planet President of Sumor XI was Burl's guest for a hunt. Sumor XI is a highly civilized planet, and life there has become tame. Its president is an ardent hunter. He liked Burl, who is still all hard muscle despite his graying hair. He and Saya have a very comfortable dwelling, and now that their children are grown they have room in it even for a planet president, if he comes as a sportsman guest. The Planet President of Sumor XI even liked the informal atmosphere of a house where pleasantly self-possessed dogs curl up comfortably on rugs of emperor-moth down that elsewhere are beyond price.
