Jen was screaming when Trevor reached them. He didn't stop to snatch up a rock. He threw himself onto the hawk that had welded itself to Hugh's back. There was a horrid slippery thrashing of wings under him, and the scaly neck of the thing was terribly strong between Trevor's hands. But not strong enough. He broke it. It was too late. When his sight cleared, Jen was staring in a strange wild way at the man and hawk lying tangled together in the dust. When Trevor touched her she fought him a little, not as though she saw him really, not as though she saw anything but Hugh's white ribs sticking out. "Jen, for God's sake, he's dead." Trevor tried to pull her away. "We've got to get away from here." There might be a chance. The black hawks were driving the humans down the canyon a little below them now, and if they could make the tumbled rocks below the cliff, there was a chance. IV He had to drag Jen. Her face had gone utterly blank. In the next minute he realized that they would never reach the rocks, and that there was no chance, none at all. Back from the winged whirl that was driving the humans, two of the hawks came darting at them. Trevor swung Jen behind him and hoped fiercely that he could get another neck between his hands before they pulled him down. The dark shadows flashed down. He could see the sun-stones glittering in their heads. They struck straight at him.... But at the last split second they swerved away. Trevor waited. They came back again, very fast, but this time it was at Jen they struck, and not at him. He got her behind him again in time. And once more the hawks checked their strike. The truth dawned on Trevor. The hawks were deliberately refraining from hurting him. "Whoever gives them their orders, the Korins or that _Other_, doesn't want me hurt!" He caught up Jen in his arms and started to run again toward the rocks. Instantly the hawks struck at Jen. He could not swing her clear in time. Blood ran from the long claw-marks they left in her smooth, tanned shoulders. [Illustration: _The lizards screamed and hissed above them. "They're coming again," the girl managed to gasp._] Jen cried out. Trevor hesitated. He tried again for the rocks, and Jen moaned as a swift scaly head snapped at her neck. So that's it, Trevor thought furiously. I'm not to be hurt, but they can drive me through Jen. And they could, too. He would never get Jen to the concealment of the rocks alive, with those two wide-winged shadows tearing at her. He had to go the way they wanted or they would leave her as they had left Hugh. "All right!" Trevor yelled savagely at the circling demons. "Let her alone! I'll go where you want." He turned, still carrying Jen, plodding after the other slaves who were being herded down the canyon.
