In that subterranean chamber of the Moon, where the angry red of still deeper fires flared fitfully; where winged demons, like evil creatures of a drug-crazed dreamer's mind, darted shrieking through the sulphurous air, it was a slender, blue-eyed girl who took control of events.

She it was who, when the explosions of detonite had ceased, saw the fall of a body from high above. She saw it strike upon a mound of dead Moon-beasts; saw the homely, human features as the body rolled to the floor; and it was she who threw herself upon it protectingly when one of the enemy wounded dragged his broken wings trailing across the stone that he might reach that human face with his distended claws.

"A man!" Anita Haldgren screamed. "It's a man—help me!" And Chet was beside her in an instant to drag the limp body to safety.

"Spud!" he shouted. "It's Spud O'Malley! He never went back! He came down here to save us!"

He grabbed up the gun where it had fallen; saw the empty magazine; then flung himself down beside the unconscious figure of Spud while he tore at the fastenings of the second weapon.

"His suit!" he shouted to the girl. "Get his suit! It's there where he fell! Bring yours and mine, too!"

He was hardly able to gage his own strength here where all weights were one-sixth of their equivalent on Earth. He stooped and swung the chunky body of Spud across his shoulder as easily as he would have lifted a child. And, having done it, he was entirely at a loss as to where to go.

Across the great room was a throng of leaping, flapping things; more were pouring in from open doors. Chet stood hesitant and bewildered, until Anita spoke.

"Come!" she called, and darted toward a narrow entrance.
