McIlvaine was touched. "Oh, I wouldn't change," he hastened to assure his friends. "I'd just be younger, that's all. They'll just work on me through the machine, and over-night I'll be rejuvenated."

"That's certainly a little trick that's got it all over monkey glands," conceded Alexander, grinning.

"Those little bugs on that star of yours have made scientific progress, I'd say," said Leopold.

"They're not bugs," said McIlvaine with faint indignation. "They're people, maybe not just like you and me, but they're people just the same."

He went home that night filled with anticipation. He had done just what he had promised himself he would do, arranging everything for his rejuvenation. Guru had been astonished to learn that people on Earth simply died when there was no necessity of doing so; he had made the offer to rejuvenate McIlvaine himself.

McIlvaine sat down to his machine and turned the complex knobs until he was en rapport with his dark star. He waited for a long time, it seemed, before he knew his contact had been closed. Guru came through.

"Are you ready, McIlvaine?" he asked soundlessly.

"Yes. All ready," said McIlvaine, trembling with eagerness.

"Don't be alarmed now. It will take several hours," said Guru.

"I'm not alarmed," answered McIlvaine.
