"All right. Bring him in."

There stepped into the room another of the mechanical Americans, but a man neither Ben Ruby nor Beeville had ever seen before. A stiff wire brush of moustache stood out over his mouth; he wore no clothes but a kind of loin-cloth made, apparently, of a sheet. The metal plates of his powerful body glittered in the lamp-light as he stepped forward. "General Grierson?" he inquired, looking from one face to another.

"I am General Grierson."

"I'm Lieutenant Herbert Sherman of the U. S. Army Air Service. I have just escaped from the Lassans and came to offer you my services. I imagine your technical men might wish to know how they operate their machines and what would be effective against them, and I think I can tell you."


CHAPTER XI

Capture

Herbert Sherman had wakened with a vague sense of something wrong and lay back in his seat for a moment, trying to remember. Everything seemed going quietly, the machine running with subdued efficiency.... It came to him with a jerk—he could not hear the motor. With that subconscious concentration of the flying man on his ship, he glanced at the instrument board first, and taking in the astonishing information that both the altimeter and the air-speed meter registered zero, he looked over the side. His vision met the familiar dentilated line of the buildings surrounding the Jackson Heights airport, with a tree plastered greenly against one of them. Queer.

His sense of memory began to return. There was the night-mail flight from Cleveland; the spot of light ahead that grew larger and larger like the most enormous of shooting stars, the sensation of sleepiness.... He remembered setting the controls to ride out the short remainder of the journey with the automatic pilot on the Jackson Heights' radio beam, since he was clearly not going to make Montauk. But what came after that?

Then another oddity struck his attention. He recalled very clearly that he had been flying over the white landscape of winter—but now there was a tree in full leaf. Something was wrong. He clambered hastily from the cockpit.
