stack of what seemed to be charts and mathematical data. A murmur outside the room brought Allen back from his contemplation of his surroundings. Men's voices; a guttural command. Then Rhool came in, walking with stiff, pseudo mechanical tread. On his heavy face was a grinning leer. Behind him there was a Gort man and woman. Allen recognized them; both had been on the spaceship and both were blamed by Rhool for the escape of Nereid and me. They came now marching stiffly erect. Their faces were impassive, but terror was in their eyes and in the tense set of their lips. And then at last came Tollgamo. Involuntarily Allen gasped at sight of him. He was a giant figure of a man, six feet six, at least. Unlike the square, robot appearance of his menials, his garments of grey metal-fabric were soft, and clinging.

"So you are one of the Earthmen, Jack Allen?" "Yes," Allen said; and then remembered Rhool's instructions, so that after a moment he added, "Yes, Master. I give you service." Tollgamo's faint ironic smile broadened; his glittering dark eyes seemed to hold a twinkle of sardonic amusement, "You learn fast." His gaze darted away; went to Rhool, and then to the Gort man and woman from the spaceship who stood with terror in their
