In the red light from the hot rocks Dean saw their faces, in which were owl eyes like those of the first one, but yellow, expressionless and stupid. Their great bodies were yellow: their outstretched hands were webbed.

For one instant, as Rawson's hand touched his pistol in its holster, a surge of fighting rage swept through him. His whole being was in a spasm of revolt against all this series of happenings that had trapped him; he wanted to lash out regardless of consequences. Then cooler judgment came to his aid.

Other figures, with faces red and ugly, expressive of nameless evil, were gathered beside the one who still played the jet of cold fire upon the walls. Like him they were naked save for a cloth at the waist and the metal straps encircling their bodies. They, too, had flame-throwers—he saw the long metal jets and their lava tips. Yet the temptation to fire into that group as fast as he could pull trigger was strong upon him.

Instead he allowed these other giant things to grip him with their webbed hands and lead him away.


he wavering light had shown many passages through the rock. Glazed, all of them. Either they had been blown through molten rock which had then solidified to give the glassy surfaces, or else—and this seemed more likely—the flame-throwers had done it. Rawson, scanning the labyrinth for some recognizable strata, had a quick vision of these caverns being cut out and enlarged, and of their walls melted just as they were being melted now—melted and hardened again innumerable times by succeeding generations of red and yellow-skinned men.

Yes, they were men. He admitted this while he walked unresistingly between two of the giants. Another went before them and lighted the way with the green ray of a flame-thrower on the melting rock. These were men—men of a different sort. Evolution, working strange changes underground, had made them half beasts, diggers in the dark, mole-men!

They were passing through a long tunnel that went steadily down. Cross passages loomed blackly; ahead of them the leader was throwing his flame upon the walls of a great vault.

Rawson had ceased to take note of their movements. What use to remember? He could never escape, never retrace his steps.
