At first the stupefied, half-awakened man struggled as if in delirium, scarcely realizing the danger. He was aware of suffering, of horror, of suffocation. Then the brain flashed into life, and he grappled fiercely with his dread antagonist. Murphy snapped like a mad dog, his lips snarling curses; but Hampton fought silently, desperately, his brain clearing as he succeeded in wrenching those claws from his lacerated throat, and forced his way up on to one knee. He felt no hatred toward this crazed man striving to kill him; he understood what had loosed such a raging devil. But this was no time to exhibit mercy; Murphy bit and clawed, and Hampton could only dash in upon him in the effort to force him back. He worked his way, inch by inch, to his feet, his slender figure rigid as steel, and closed in upon the other; but Murphy writhed out of his grasp, as a snake might. The younger man realized now to the full his peril, and his hand slipped down to the gun upon his hip. There was a sudden glint in the faint starlight as he struck, and the stunned maniac went down quivering, and lay motionless on the hard ground. For a moment the other remained standing over him, the heavy revolver poised, but the prostrate figure lay still, and the conqueror slipped his weapon back into its leather sheath with a sigh of relief. The noise of their struggle must have carried far through that solemn stillness, and no one could guess how near at hand might be bands of prowling savages. Yet no sound came to his strained ears except the soft soughing of the night wind through the trees, and the rustling of grass beneath the tread of the horses. With the quick decision of one long accustomed to meet emergencies, Hampton unbuckled the lariat from one of the led animals, and bound Murphy's hands and limbs securely.
