Specifically, Psychontact had the job of co-ordinating the colonies into a working whole, thus hoping to insure that the whole would be greater—and stronger—than the sum of its parts. "Colonies! Colonies!" blazed Parmay, one morning. "You'd think we were bacteriological cultures!" "Well," answered Alina, "of course we aren't." "Well of course we are!" Parmay snapped back, "We're trying to spread, disease-like, over the galaxy in order to counteract the effects of another type of organism which is trying to do the same."

Twenty minutes later, the phone chimed. "Damn!" Parmay blistered. He kissed Alina once more, then answered. Lon Tallen, commander of the HC-36, greeted him from the screen.

But he was only checking them with half a mind; the other half was on something Alina had said. Fanatic? Possibly. After living with a threat that hadn't materialized in fifty decades, most of the human race viewed the alien threat with apathy. A man worked to prevent their spread—or rather to increase the spread of genus Homo—but after all, nothing
