General Beemish was delighted. Everyone was delighted. "No trouble at all," said Beemish, who had already made a phone call that had galvanized two thousand scientists and technicians into action. "We'll have it for you in no time."

"I certainly hope so," said Keeter. Some of the flippancy had left him, and it was apparent that this new bid for assistance was causing him considerable embarrassment—for a short time, anyway.

"Yes sir," said Beemish, grinning. "Glad to be of help, in fact, we're flattered that you'd let us, primitive as we are, help at all. We primitives don't often have an opportunity to do this sort of thing, you know." Beemish believed in rubbing while the rubbing was good.

The solenoids, forty in all, were delivered the following morning. They were packaged in a small black box lined with velvet. This time Keeter made no comment about the packaging. Instead, he rose from his chair in the conference room, tucked the box under an arm, and addressed the group. "Gentlemen, I'd like you to know just how much I appreciate this favor. Evidently, I misjudged your level of technology, and for this I apologize. I don't know how I can repay you for this latest favor, but if you'd like, I'll be glad to formally submit your planet's application for Federation Membership as soon as I return to Aldebaran."

"When will that be?" asked Senator Humper unceremoniously.

"Oh, about ten of your years, at a guess."

"Ten years! My God, man. Can't you do something sooner?"

"Well—I suppose, I could administer the first two parts of the test myself. Why, yes, I suppose I could drop off your samples and your specimen at the Federation branch laboratory in Andromeda—."

"Wonderful!" shouted Beemish. "When do we begin?"

He was genuinely awed when three weeks later they began loading enormous quantities of Z-67As into his ship. He did not check the stuff, but had no doubts that it was, atom for atom, identical to the sample of fuel he had given them.
