Brand nodded, finding his head almost too heavy for his neck to move. Sweat beaded his forehead—sweat that trickled heavily off his face like drops of liquid metal.

With a tremendous struggle he got to his knees beneath the master-switch. There he found it impossible to raise his arms; but, leaning back against the control board and so getting a little support, he contrived to lift his body up enough to touch the down-slanting lever with his head and move it back along its slot a fraction of an inch. The giant coils hummed a note lower; and some of the smashing weight was relieved.

"That does it, I think," Brand panted, his voice husky with exhaustion and triumph.

He began to crawl laboriously toward the nearest street exit. "On our way!" he said vibrantly. "To the space ship! We leave for Earth at once!"


lowly, fighting the sagging weight of their bodies, the two Earthmen inched their way to the street, helping Greca as they went. Among the sprawled forms of the Rogans they crept, with great dull eyes rolling helplessly to observe their progress, and with feeble squeals of rage and fear and malediction following their slow path.

On the street a strange and terrible sight met their eyes.

Strewn over the metal paving like wheat stalks crushed flat by a hurricane, were thousands of Rogans. Not a muscle of their pipe-like arms or legs could they move. But the gravity that crushed them rigidly to the ground did not quite hold motionless the shorter and more sturdily built slaves.

Among the thousands of squealing, panting Rogans that lay as though paralyzed on the metal paving, crawled equal thousands of Greca's enslaved people. Their eyes flamed with fanatic hate. And methodically—not knowing what had caused their loathed masters to be stricken helpless, and not caring as long as they were helpless—the slaves were seeking out the shock-tubes that here and there had fallen from the clutch of Rogan guards. Already many had found them; and everywhere gangling, slimy bodies were melting in oily black smoke that almost instantly vanished in thin air.
