members, taller than Sporr, almost as tall as I. Her figure was mature, generous, but fine, and set off by a snugly-draped robe as red as her dyed cascade of hair. Red-dyed, too, were the tips of her fingers, and her lips were made vivid and curvy beyond nature by artificial crimson. She made a bow toward me, smiled a little, showing most perfect white teeth. She began: "Dondromogon began with the First Comers. Many ages they ruled here, the Fifteen of them. Forever they were fifteen, for when one died, another was bred; when one was born, the oldest or least useful was eliminated. It was they who planned and began this shelter-city, found the elements that support life and give comfort. "Others came, from far worlds. The Fifteen changed their policy of a fixed number, and became rulers of the new colonists. But after some study, it was decided to set a new limit. Seven hundred was decided upon, and seven hundred we still remain." "Wait," I interrupted. "You mean that, when new children are born among you, someone must die?" She nodded. "Exactly as with the Fifteen. We eliminate the least useful. Sometimes we eliminate the child itself. More often, an older and worn-out individual." I thought that I sensed an uncomfortable wriggle in Sporr, behind me. "Why is this?" I demanded. "Because, Yandro, there cannot be room and supplies enough for a greater number." I scowled to myself. So far I had seen luxury enough in Dondromogon's chambers and tunnels. But there remained so much to learn. "Go on," I bade her. She nodded again, and obeyed: "Thus we on Dondromogon live and have lived. This world is ours, its good and evil. But," and her voice, from a soft, shy murmur, turned hard, "there are those who do not wish it so. The Newcomers—the invaders!" "Ill be their fate," growled Gederr beside her, as if rehearsed. "They came to us, not long ago in years ... but I forget, Yandro does not know as yet the length of Dondromogon's year, or Dondromogon's day. They came, then, no longer ago than the time needed for a baby to become a child." Three years of my own reckoning I decided, and wished she had not mentioned babies and children. I still disliked that arbitrary survival-of-the-fittest custom. "Where did they come from?" I asked.
