Young Inver, who had returned to the bedroom, was standing there, listening to all this. Now his expressive eyes lighted up, and he touched Hanlon's arm. When the young S S man turned to face him, Inver breathlessly asked, "Was that the way my caval got well so fast?"

Hanlon grinned at him. "I knew it was your favorite mount, and I didn't want to see it destroyed."

He turned quickly back to help his father get up. The admiral found that, while he was still a little shaky, he could stand up without dizziness. The Ruler had sent his uniform jacket out to be cleaned and mended, and this Newton donned. Soon the men were seated about the table the servants had set up, eating the splendid breakfast they brought and served.

Meantime, the five talked about the problem that so much interested them all, and that meant so much to all the peoples of their worlds.

"Our Colonial and Survey Bureaus are constantly seeking throughout space for other planets having intelligent races, and we feel sure yours will not be the last we'll find," Admiral Newton told the Ruler and his son. "It is egotistical and silly to think we Terrans are the only civilized peoples in the universe."

"Chances are we'll find others who are as far ahead of us in intelligence, science and technologies as you Estrellans are ahead of us in ethics," Hanlon added honestly.

Amir and Inver looked up in astonishment at that simple statement. "You ... you actually mean ... honestly ... that you Terrans do not believe you are the highest form of life in the universe?" Inver put their questioning into words.

"Great John, no!" Admiral Newton exploded. "Oh, I suppose," he added more slowly, "that there are some earth people who may still feel that way, but the majority of us do not, especially those who have travelled at all extensively. We used to think that; used to believe, hundreds of years ago, that we were the only intelligent life in the cosmos. But we know better now that we're spreading out. I, personally, have been on at least six planets that contain intelligent life that did not stem from Terra, although yours is the highest of the six, and none of the rest are yet at the point where they can be asked to affiliate with the Federation as equal members. But those others are being taught and coached as best we can—and as much as they want to be. In a few more generations they'll probably have reached the point where they will be ready to be seriously considered for equality status with us, as far as Federation membership is concerned."

"Just how do you determine the fitness of a race for membership in your Federation?" Inver leaned forward, his expressive eyes questioning. His father started to rebuke him for his forwardness, but the admiral interrupted.

"No, that's a good question, and we're glad to answer it—just as we're glad to answer any questions to which we know the answers. As to this one, we look first for signs of intelligence great enough to enable the people to govern themselves without continual warfare," he said earnestly. "Their knowledge of science and technology is not so important, we feel, although their ability to learn is. Some races will probably never have real need for machines of any sort—races like the plant-men of Algon, where Captain Hanlon was recently instrumental in freeing them from slavery."
