"They want to rejuvenate me," said McIlvaine, with a certain shy pleasure.

"What's that?" asked Alexander sourly.

"They say they can make me young again. Like them up there. They never die. They just live so long, and then they rejuvenate, they begin all over. It's some kind of a process they have."

"And I suppose they're planning to come down and fetch you up there and give you the works, is that it?" asked Alexander.

"Well, no," answered McIlvaine. "Guru says there's no need for that—it can be done through the machine; they can work it like the disintegrators; it puts you back to thirty or twenty or wherever you like."

"Well, I'd like to be twenty-five myself again," admitted Leopold.

"I'll tell you what, Mac," said Alexander. "You go ahead and try it; then come back and let us know how it works. If it does, we'll all sit in."

"Better make your will first, though, just in case."

"Oh, I did. This afternoon."

Leopold choked back a snicker. "Don't take this thing too seriously, Mac. After all, we're short one of us now. We'd hate to lose you, too."
