"You will now return to your place of confinement. After you have recovered you will be taken in hand by your fellow-slaves and shown your duties. And if your instinct for self-preservation is only one-tenth normal, you will never again be such a stupid sub-animal fool as to attempt to resist Xantra—to fly in the face of the inevitable!"

The sharp, staccato voice in Clee's brain stopped; his nausea began to leave him; his helmet was removed; and had he been looking he might have seen the other one slowly materialize on the table. The ordeal was over just in time, for the last remnants of his strength was giving out—as was Jim's. The two Earth-men slumped down, and would have fallen but for the telepathic will, stronger than theirs, that forced them erect again. There came a very strong compulsion to return to their cell, and bruised, stumbling, their nerves still afire from their strange stabbing pains, they made their way back.

They fell to the floor and passed into unconsciousness—beaten, subdued. Slaves....


fter a long blank interval a distinct thought crossed Clee's mind. He was in heaven, and an angel voice had spoken. There it was again! Cool hands were stroking his wrists and forehead. He opened his eyes and looked, but seeing no one closed them again.

The Voice returned, and two of the words which kept repeating were somehow familiar. "So sorry ... so sorry...." The Voice was low and cool and feminine. And someone was bathing his battered head.... He rolled over and got up on one elbow. He still could see no one.

The Voice said: "Oh, I'm so glad you're better! I thought you'd never come to!"

Mechanically Clee asked: "Who are you?"

"Vivian Gray," came the quick answer; "from Boston. And you?"
