Still in his trance, with his heart pounding in his throat till he thought it would burst, Harley watched the further awful developments. The eyelids remained opened, disclosing two great, dull eyes like poorly polished agates, which stared expressionlessly at him. There was a convulsion like a minor earthquake, and the mass shortened and heightened its bulk, raising itself to a sitting posture. The three hinged, irregular arms suddenly extended themselves to the full in a thrust that barely missed him. They were tipped, those arms, with immense claws, like interlocking, rough-hewn stone fingers. They crashed emptily together within a few feet of Harley. Then, and not till then, did the paralysis of horror loose its grip on the human. He tore his ray-pistol from its holster and pointed it at the incredible body. An angry, blue-green cone of light leaped from the muzzle, and played over the mighty torso. Nothing happened. He squeezed the trigger back to the guard. The blue-green beam increased in intensity, and a crackling noise was audible. Under that awful power the monster should have disappeared, dissolved to a greasy mist. But it didn't. The light beam from the ray-gun died away. The power was exhausted. It was only good for about ten seconds of such an emergency, full-force discharge, after which it must be re-charged again. The ten seconds were up. And the gigantic creature against which it had been directed had apparently felt no injury from a beam that would have annihilated ten thousand men. The now useless ray-pistol slipped from his limp fingers. Stupefied with horror at the futility of the deadly Randchron ray against this terrible adversary, he stood rooted to the spot. Then the thing reached for him again; and his muscles were galvanized to action--to instinctive, stupid, reasonless action. Screaming incoherently, mad with horror of the stone claws that had clutched at him, he turned and ran. In great leaps he bounded away from the accursed lake and made for the taller trees and thicker vegetation at a distance from the shore. It was the worst thing he could have done. There was a chance that he could have reached his Dart, had he thought of it, and soared aloft out of reach. But he thought of nothing. All he wanted to do, in that abysmal fear that can still make a mindless animal out of a civilized man, was to run and hide--to get away from the fearful monster that had risen up to glare at him with those stony, pitiless eyes, and to reach for him with two-fingered bands like grinding rock vises. * * * * * Just as the sun fell below the rim of the asteroid, plunging it into a darkness only faintly relieved by the light of the stars, he crashed into the deeper underbrush. A trailing creeper tripped him in his mad flight. He fell headlong, to lie panting, sobbing for breath, in the thick carpet of blood-colored moss.
