"Now as I was saying, Roger Bacon--"

I ceased to listen. When van Manderpootz is determined to finish a statement, interruptions are worse than futile. As an ex-student of his, I know. So I permitted my thoughts to drift to certain personal problems of my own, particularly Tips Alva, who was the most pressing problem of the moment. Yes, I mean Tips Alva the 'vision dancer, the little blonde imp who entertains on the Yerba Mate hour for that Brazilian company. Chorus girls, dancers, and television stars are a weakness of mine; maybe it indicates that there's a latent artistic soul in me. Maybe.

I'm Dixon Wells, you know, scion of the N. J. Wells Corporation, Engineers Extraordinary. I'm supposed to be an engineer myself; I say supposed, because in the seven years since my graduation, my father hasn't given me much opportunity to prove it. He has a strong sense of value of time, and I'm cursed with the unenviable quality of being late to anything and for everything. He even asserts that the occasional designs I submit are late Jacobean, but that isn't fair. They're Post-Romanesque.

Old N. J. also objects to my penchant for ladies of the stage and 'vision screen, and periodically threatens to cut my allowance, though that's supposed to be a salary. It's inconvenient to be so dependent, and sometimes I regret that unfortunate market crash of 2009 that wiped out my own money, although it did keep me from marrying Whimsy White, and van Manderpootz, through his subjunctivisor, succeeded in proving that that would have been a catastrophe. But it turned out nearly as much of a disaster anyway, as far as my feelings were concerned. It took me months to forget Joanna Caldwell and her silvery eyes. Just another instance when I was a little late.

Van Manderpootz himself is my old Physics Professor, head of the Department of Newer Physics at N. Y. U., and a genius, but a bit eccentric. Judge for yourself.

"And that's the thesis," he said suddenly, interrupting my thoughts.

"Eh? Oh, of course. But what's that grinning robot got to do with it?"

He purpled. "I've just told you!" he roared. "Idiot! Imbecile! To dream while van Manderpootz talks! Get out! Get out!"

I got. It was late anyway, so late that I overslept more than usual in the morning, and suffered more than the usual lecture on promptness from my father at the office.

Van Manderpootz had forgotten his anger by the next time I dropped in for an evening. The robot still stood in the corner near the window, and I lost no time asking its purpose.

"It's just a toy I had some of the students construct," he explained. "There's a screen of photoelectric cells behind the right eye, so connected that when a certain pattern is thrown on them, it activates the mechanism. The thing's plugged into the light-circuit, but it really ought to run on gasoline."

"Why?"

"Well, the pattern it's set for is the shape of an automobile. See here." He picked up a card from his desk, and cut in the outlines of a streamlined car like those of that year.
