"We're out, all right," Lawton said, hoarsely. "Just in time, too. Skipper, you'd better issue grog all around. The men will be needing it. I'm taking mine straight. You've accused me of being primitive. Wait till you see me an hour from now." Dr. Stephen Halday stood in the door of his Appalachian mountain laboratory staring out into the pine-scented dusk, a worried expression on his bland, small-featured face. It had happened again. A portion of his experiment had soared skyward, in a very loose group of highly energized wavicles. He wondered if it wouldn't form a sort of sub-electronic macrocosm high in the stratosphere, altering even the air and dust particles which had spurted up with it, its uncharged atomic particles combining with hydrogen and creating new molecular arrangements. If such were the case there would be eight of them now. _His_ bubbles, floating through the sky. They couldn't possibly harm anything--way up there in the stratosphere. But he felt a little uneasy about it all the same. He'd have to be more careful in the future, he told himself. Much more careful. He didn't want the Controllers to turn back the clock of civilization a century by stopping all atom-smashing experiments. Transcriber's Note: This e-text was produced from Comet July 1941.
