"Could be. There are old radiation traces. But these aliens had, I'm sure, progressed beyond atomics. Suppose, just suppose, they could tamper with the weather, with the balance of the planet's crust? We don't know the extent of their powers, how they would use them. They had a colony here once, or there would have been no guide tape. And that is all we are sure of."
"Suppose"—Ross rolled over on his stomach, pillowed his head on his arms—"we could uncover some of that knowledge—"
The twitch was back at Ashe's lips. "That's the risk we have to run now."
"Risk?"
"Would you give a child one of those hand weapons we found in the derelict?"
"Naturally not!" Ross snapped and then saw the point. "You mean—we aren't to be trusted?"
The answer was plain to read in Ashe's expression.
"Then why this whole setup, this hunt for what might mean trouble?"
"The old pinch, the bad one. What if the Reds discover something first? They drew some planets in the tape lottery, remember. It's a seesaw between us—we advance here, they there. We have to keep up the race or lose it. They must be combing their stellar colonies for a few answers just as furiously as we are."
"So, we go into the past to hunt if we have to. Well, I think I could do without answers such as the Baldies would know. But I will admit that I would like to know what did happen here—two, five, ten thousand years ago."
