The day after the American President departed, Barlow flew into a rage. Across his specially built desk were supposed to flow all Poprob high-level documents and this thing—this outrageous thing—called Poprobterm apparently had got into the executive stage before he had even had a glimpse of it!

He buzzed for Rogge-Smith, his statistician. Rogge-Smith seemed to be at the bottom of it. Poprobterm seemed to be about first and second and third derivatives, whatever they were. Barlow had a deep distrust of anything more complex than what he called an "average."

While Rogge-Smith was still at the door, Barlow snapped, "What's the meaning of this? Why haven't I been consulted? How far have you people got and why have you been working on something I haven't authorized?"

"Didn't want to bother you, Chief," said Rogge-Smith. "It was really a technical matter, kind of a final cleanup. Want to come and see the work?"

Mollified, Barlow followed his statistician down the corridor.

"You still shouldn't have gone ahead without my okay," he grumbled. "Where the hell would you people have been without me?"

"That's right, Chief. We couldn't have swung it ourselves; our minds just don't work that way. And all that stuff you knew from Hitler—it wouldn't have occurred to us. Like poor Black-Kupperman."

They were in a fair-sized machine shop at the end of a slight upward incline. It was cold. Rogge-Smith pushed a button that started a motor, and a flood of arctic light poured in as the roof parted slowly. It showed a small spaceship with the door open.
