says that it can only survive as a whole, which must be composed of such-and-such parts. This society had suffered trauma, from the predicted dissolution of Phaedra's sun. Very many lives would be lost, unnecessarily, unless the results of that traumatic experience could be healed. But Calhoun's obligation was not to be stated in such terms to these young men. "Who is running things?" demanded Calhoun. "A man named Walker said his son was bossing things here. He was pretty bitter about it, too! Who's looking after the distribution of food, and who's assigning who to raise more, and who's seeing that the small children get fed and cared for?" The spaceport gang looked blank.

With a spinning of wheels, it shot into immediate high speed. The dark-browed younglings drove with hair-raising recklessness and expertness. He traversed the city in minutes, and at a speed which allowed Calhoun only glimpses. But he could see that it was almost unoccupied. Canopolis had been built by the
