Dusty did not hear the Marandanian. He was thinking of Los Angeles suffering under the effects of a variable star. Or, rather, he was trying to visualize such a condition. His imagination provided alternating scenes of icy blast and deadly heat, but Dusty's overall technical knowledge was far too meager to offer him even a slight glimpse of the real truth. To merely consider Sol varying about one hundred to one in brightness and warmth every three days was as far as Dusty could go. What would happen to the weather, the general climate, agriculture, and all of the rest were far beyond Dusty.
Even so, the sketchy picture provided Dusty with enough data to say, "Why, we couldn't go on living on Earth at all!"
"Right. Which is why I'm here."
"But you said—"
Scyth smiled confidently. "I'm not here to preside over the death of your part of our human race," he said. "I—"
"Our part of your human race—?" exploded Dusty.
"Of course," said Scyth in a matter-of-fact tone. "So far as we know, human life was first spawned on Marandis. About thirty thousand years ago we became galactic in scope, spreading out, colonizing, expanding, exploring. Many expeditions left home and were lost. But I'll not belabor this any more, just accept my word for the following: nowhere in this galaxy have we found intelligent life that did not spring as an offshoot of misplaced Marandanian culture."
"How can you be so damned certain?"
"The easiest way is to check the cross fertility. It has always worked, to date at least," said Scyth, inadvertently letting his eyes slide up and down the very pleasant sight of Barbara Crandall's body. Barbara knew Scyth's contemplative look and she reacted as any uninhibited woman does when some man is measuring her. The deep high breath raised her breasts and flattened her stomach even though she had no great yen toward wanton promiscuity.
"I gather, then, that you and your gang are going to do something about us?" she asked.
