Her voice was a thin thread in the keening murmur of sounds. And it was worried. Ed and Barbara both craved the reassuring presence of someone of experience here, where everything was changed--where minute gusts of air seemed bent on hurling you upward, so that you would float helplessly, like a mote. You stood up gingerly, meaning to try walking a step. But that mode of locomotion seemed not only unsafe here but impractical. You could be swept away, and in the vastness all around, how could one mote find another again? Too much of what you were used to was lost already. Even the habit of walking no longer functioned properly. The air was a buoyant, resisting substance, a prickling presence of individually palpable molecular impacts, and there was little traction for one's feet. Perhaps, then, here you swam in the air. Ed spoke at last: "My uncle can't be far away. He'll come to us. It's been only a moment." Barbara clung to him, afraid. "Eddie, am I me anymore? Can I even find old ways of talking, and old subjects to talk about? Here? Everything seems too different. Damn--I never could accept the idea of there being two of anyone! Us up in those other tanks--giants asleep. And yet us here! Maybe we're different already--shaped by other surroundings! And remember how little we are and how helpless. Moving a couple of inches would be like walking a mile. And we came here to see if we could find a way to straighten out the giant affairs at home. We're _androids_ now, aren't we? A special kind. But we still have the capacity for the old emotions. Damn it again, Eddie, everything around us in this place is so strange. But it's beautiful, too." He patted her shoulder and said nothing. But her thoughts paralleled his own. Suddenly there was a rumble, like distant thunder. In a more familiar size level, it would have been a clink and a thud, coming through many yards of granite. They both recognized it. Ed even chuckled. "Whoever or whatever was following the canary machine," he said. "Remember?" Just then Mitchell Prell's simulacrum appeared, a comic, bearded figure wrapped in a few strands of lint that suggested woven twigs. He swam out of the depths of atmosphere--the fall-guy of an era that had stumbled over its own achievements. And in several of those very achievements, he had taken refuge. He alighted near Ed and Barbara and wrung their hands cordially. Then words spilled out of him excitedly: "Ed. Barbara. We've got to hurry. But first we should put our minds straight about one another. I know that back home you were on the side of responsibility and good sense. Well, so am I. There haven't been many new quirks added to my viewpoint since you first knew me, Eddie. I want knowledge to blossom into all that it can give us. I think you do, too. Now tell me how you feel." Mitchell Prell could still inspire Ed Dukas. Even here, at this opposite, smaller end of the cosmos, he imagined again his splendid towers of the future.
