An’ at that instant the pattern of relays that Joe had turned on snapped off, all the offers of directive service stopped flashin’ on logic screens everywhere, an’ peace descended on the earth.

For everybody else. But for me—Laurine come to town. I have often thanked Gawd fervent that she didn’t marry me when I thought I wanted her to. In the intervenin’ years she had progressed. She was blonde an’ fatal to begin with. She had got blonder and fataler an’ had had four husbands and one acquittal for homicide an’ had acquired a air of enthusiasm and self-confidence. That’s just a sketch of the background. Laurine was not the kinda former girlfriend you like to have turning up in the same town with your wife. But she came to town, an’ Monday morning she tuned right into the middle of Joe’s second spasm of activity.

The Korlanovitch kids had turned him on again. I got these details later and kinda pieced ’em together. An’ every logic in town was dutifully flashin’ a notice, “If you want to do something and don’t know how to do it—ask your logic!” every time they was turned on for use. More’n that, when people punched for the morning news, they got a full account of the previous afternoon’s doin’s. Which put ’em in a frame of mind to share in the party. One bright fella demands, “How can I make a perpetual motion machine?” And his logic sputters a while an’ then comes up with a set-up usin’ the Brownian movement to turn little wheels. If the wheels ain’t bigger’n a eighth of an inch they’ll turn, all right, an’ practically it’s perpetual motion. Another one asks for the secret of transmuting metals. The logic rakes back in the data plates an’ integrates a strictly practical answer. It does take so much power that you can’t make no profit except on radium, but that pays off good. An’ from the fact that for a coupla years to come the police were turnin’ up new and improved jimmies, knob-claws for gettin’ at safe-innards, and all-purpose keys that’d open any known lock—why—there must have been other inquirers with a strictly practical viewpoint. Joe done a lot for technical progress!
