Terra had been the center of the civilized universe. But the long migration starward, especially after the fall of the First Empire, drained off the most venturesome elements of the population. That drain went on for thousands of years. Sol was backward, ruined and impoverished by the remorseless price of empire, helpless before the storms of barbarian conquest that swept back and forth between the stars. Even after peace was restored, there was nothing to hold a young man or woman of vitality and imagination here—not when you could go toward Galactic center and join the new civilization building out there. Space-traffic came ever less frequently to Sol; old machines rusted away and were not replaced; best to get out while there was still time. Eventually there was a fixed psychosomatic type, one which lived close to the land, in primitive changeless communities and isolated farmsteads—a type content to gain its simple needs by the labor of hand, horse, or an occasional battered engine. A culture grew up which increased that rigidity. So few had visited Earth in the last several thousand years—perhaps one outsider a century, stopping briefly off on his way to somewhere else—that there was no challenge or encouragement to alter. The Terrans didn't want more people, more machines, more anything; they wished only to remain as they were. You couldn't call them stagnant. Their life was too healthy, their civilization too rich in its own way—folk art, folk music, ceremony, religion, the intimacy of family life which the Galactics had lost—for that term. But to one who flew between the streaming suns, it was a small existence. Kormt's voice broke in on his reverie. "Dreams, triumphs, work, deeds, love and life and finally death and the long sleep in the earth," he said. "Why should we want to change them? They never grow old; they are new for each child that is born." "Well," said Jorun, and stopped. You couldn't really answer that kind of logic. It wasn't logic at all, but something deeper. "Well," he started over, after a while, "as you know, this evacuation was forced on us, too. We don't want to move you, but we must." "Oh, yes," said Kormt. "You have been very nice about it. It would have been easier, in a way, if you'd come with fire and gun and chains for us, like the barbarians did long ago. We could have understood you better then." "At best, it will be hard for your people," said Jorun. "It will be a shock, and
