"I've got you, Dent," he screamed in triumph, hovering above the three, while the wings drummed and vibrated till they seemed the mere play of light and shadow about Tode's shoulders. "Halt, or I'll blast your body and soul to hell! Halt, or I'll kill her!"

The deadly tube was pointing steadily at Lucille's body as Tode hovered ten feet overhead, perfectly still save for the whirring wings. The three stopped dead, and Tode, with a shout of triumph, began calling the Drilgoes, who swarmed forward out of the undergrowth.

Huge brown bodies, nude save for their skins of jungle-cat or serpent, they emerged, quickly forming a ring about the three prisoners. Tode fluttered to the ground.

"Fools, did you think you could escape that way?" he asked. "As for you, Dent. I'm going to convince you of the reality of four-dimensional space as you would not be convinced in the old days. Do you know what I'm going to do with you? I'm going to strip the skin from you with the ray, and take you into the anatomical room at Columbia University and leave you there as an exhibit, Dent!"

Tode grinned like a madman. But Jim was looking past him, at something that had suddenly appeared upon the far horizon.


t was a round disc of bluish white, a disc like the moon, but slightly smaller, a disc that flickered as if it had an eyelid that was being winked repeatedly. Simultaneously screams broke from the throats of all the Drilgoes. They stampeded.

Tode whirled about and saw. With a curse he leaped into the air and whirred away.

Out of that disc a slender, blue-white beam shot suddenly, driving a pathway through the fog, and disclosing the dark depths of the valley.
