"There were moments when I felt pretty bitter," he said, in not too friendly a fashion. "But in the main I'm with what you just said--all the way. I put my life on it as a pledge." Barbara nodded solemnly. "Thanks," Prell answered, the breath that he'd drawn for speech sighing out of him. "I'm more grateful than I can tell. You two may think that we're too tiny--that our size makes us powerless. I don't believe that's true. I was on Earth as I am, you know. I went there and back--undetected--on space liners. But while on Earth I missed many opportunities to act against danger. Maybe I'd been here too long, down close to the basic components of matter, studying them. And I went to Earth poorly equipped in both materials and experience. Well, I think you can see how it was. Let it go for now. Visitors are at our door. I suppose we've got to try to meet them in the manner that they deserve." "Call the shots!" Ed said impatiently. Mitchell Prell smiled rather wistfully. "The main part is done," he replied. "I set the small remote controls of the large vats for revival of the bodies in them--our larger selves. That was why I was delayed in getting to you here. They are colossi. They cannot hide. And they must be defended. I'm sorry, they are better able to defend themselves than we are to defend them. At least they will have a better chance alive than inert. Revival takes a little time, but in a moment you will see." Ed did not quite know what to think about this action on his uncle's part--whether to agree to it or to suspect that it was somehow a mistake. Circumstances were too strange here, and he was too inexperienced. And the whole situation itself was fraught with confusion for him. Two selves, both named Edward Dukas? It was not a new circumstance in the ideas of the times. You knew that it could be. Yet it remained a muddle of identities hard to straighten out. Barbara clung to him again, her feelings doubtless similar to his own. "It's happening," she whispered. And it was. From their perch on the scored, glassy surface under a miniature electron microscope, they looked out past the minute tanks and the attendant cables, crystals and apparatus that had given them special being, and across the shimmering void of air, they saw those other vats, glassy, too, and tall as mountains. It seemed then that the mountains opened, unfolded, grew taller, disgorged Atlases that stepped dripping over a cliff wall. There was no connection of mind now--these three giants were other people, for the link had been broken in the past. There was no blending of consciousness.
