man.' And Underwood dared not trust that glib explanation. Many others besides Underwood found they could no longer endure the instability of their own culture. Among these were many of the world's leading scientists. Most of them went to the jungle lands of Venus. The scientific limitations of such a frontier existence had kept Underwood from joining the Venusian colonies, but he'd been very close to going just before he got the offer of Chief Physicist with the Smithson Institute expedition in the asteroid fields. He wondered now what he'd have done if the offer hadn't come. The interphone annunciator buzzed. Underwood turned off the news as the bored communications operator in the control room announced, "Doc Underwood. Call for Doc Underwood." Underwood cut in. "Speaking," he said irritably.

Underwood's mind, which had been half occupied with mulling over his personal problems while he talked with Terry, swung startledly to what the archeologist was saying. "You mean that you've found a material the Atom Stream won't touch? That's
