"Hurry, for God's sake!" gasped Dex.

Brand threw down the lever till it stuck. At once that invisible ocean poured crushingly over them, throwing them to their knees and sweeping the Rogans flat on their hideous faces just as half a hundred tubes were flashing down to point at the Earthmen.

"More—if you can!" grated Dex, whirling this way and that and spraying the massed Rogans with his death-dealing tube. Dozens went up in smoke under that discharge; but other dozens remained to raise themselves laboriously and slowly level their suddenly ponderous weapons at the Earthmen.

Brand set his jaw and threw all his weight on the lever. It bent a little, caught at the neutral point—and then jammed down an appreciable distance beyond it.


nstantly the blue streamers, that had stopped their humming progress from coil to coil with the movement of the switch to neutral, started again in reversed direction. And instantly the invisible ocean pressed down with appalling, devastating force.

Greca and Brand and Dex were flattened to the floor as if by blankets of lead. And the scattered Rogans about them ceased all movement whatever.

"Oh," sobbed Greca, fighting for breath. "Oh!"

"We can't stand this," panted Dex. "We've fixed the Rogans, all right. But we've fixed ourselves, too! That lever has to go up a bit."
