"They were queer folk, the people of Moorn," Gerry said moodily. "I suppose they were afraid they might get dragged into the affairs of the planet in spite of themselves, and simply moved the whole city off to some distant and unknown planet."

"But how could they do that?" McTavish said. Gerry shrugged.

"Ask me another! How could they make the place invisible? We know they did that, we don't know how much further their science went. Anyway—I'm going to be glad to get back to Earth for a while. I guess we're ready to start."

He turned to look at Closana for a moment. The girl had laid aside her battered armor for her customary bright loin cloth and golden breast plates. She shook back her long golden hair and faced him with a smile.

"Want to come back to Earth with me, Closana?" he asked.

"Either that—or the ship goes back without its captain," she said quietly. Gerry laughed.

"Darling, I feel sorry for any Earth-woman who ever concludes you're some shy little stranger she can patronize. Well—the trails of interplanetary space are long and we'd better get going. All aboard!"
