Consciousness came slowly back to Allan Dane. At first he was aware, merely, that he was alive. That was astonishing enough. Even if the orange beam had not killed him with its heat, the gas should have struck his leather suit. The Easterners could not be behind his own forces in their development of that terrible weapon.

Allan felt a coolness on his face, his hands, that could mean only that his helmet and gloves had been removed. He heard movement, and opened his eyes.

At first he could see only blueness, pale and lambent. He gazed dully up at a lustrous, glasslike substance that arched above him. The sound of some one moving came again, and Allan turned his head to it. His neck muscles seemed stiff, that simple motion drew tremendously on his strength.

About fifteen yards away, a man bent over a transparent, boxlike contrivance in which something fluttered. From this device a metal tube angled away into the wall. There was other apparatus on the long table at which the man was—

"At last! Clear at last!" a mellow, rounded voice exclaimed jubilantly.

"Clear? Are you sure, Anthony, are you sure?" This other voice, throbbing with vibrant repression as if its owner feared to believe longed-for tidings come at last, was a woman's. As the man half turned, its owner came between him and Allan. All he could see of them was that the one called Anthony was very tall, and thin, and the woman almost as tall, and that both wore hooded white robes, the woman's falling to her heels, the man's to his knees, waist-girdled with black cords.

"Look for yourself, Helen."

She bent over the transparent cage. "Oh Anthony, how wonderful!"

Allan attempted to rise. He was unutterably weak; to move a finger was a gigantic task, to do more impossible. He tried to call out. No sound came from his straining throat.

The couple straightened. The man spoke, too low for Dane to hear. Each took something from the table, something that gleamed metallically. Then they turned—and Allan saw what the white robes clothed!
