The tire was beginning to harden. He bent again over the pump, driving himself to the labor. At last it was done--done well enough, at least. He disconnected the pump and tossed it into the car. A word from Claire broke in upon him. "What's that! Something moved against the sand--oh! It's a snake!" He laughed unsteadily as he looked. A snake in truth--an incoherent, feeble object that slipped across the sand and blended there, shapeless and indistinct; a stark-blind thing, a living volute of death and venom. Murray flung a handful of sand. The reptile lashed out viciously at the air. "A rattler shedding its old skin; blind and deadly poisonous at this season," he said. "I remember Mackintavers warned us about it--no rattles, no sound at all!" He laughed, for his own voice astonished him; it sounded thin and tenuous, far away, distant. With a distinct effort of the will, he forced himself to stoop after the jack; disengaging it, he rose and lifted it into the tonneau, with strange effort. Claire got out of the car in order to let him in more easily, but he did not climb into the shadow of the top. Instead, he held to the open door for an instant, then sank down upon the running board. "I think I'll rest," he said, looking from bloodshot eyes at the figure of the girl beside him--the slender, cool figure that seemed to defy the sunlight. "Clairedelune--it comes from the troubadours, that name--the softly sweet glory of the silven moonlight--the sheer beauty that wrings the heart and soul of a man with pain and sweetness----" His head jerked suddenly. As though some inner instinct had wakened to fear and danger within him, his voice broke out sharply, clearly: "No cold water, mind! It kills--no cold water, mind!" Not until his head fell back into the car doorway did Claire Lee realize that something was actually wrong. She had thought him babbling a bit--now, for a terrible moment, she thought him dead. Yet his last words abode with her, remained fixed and distinct in her mind. No cold water! His heart was beating; he was not dead after all. He must have realized, in that moment, what the trouble was! Sunstroke. She realized it now, realized it with a fearful sense of her own futility. She had no water, except the ice-cold water in the porous waterbags beside the car! Hesitation and fear, but only for an instant. She seized the nearest bag, her hands trembling in desperate haste, and jerked out the cork. Part of that precious fluid she poured into the sands, then stumbled to the front of the car and stooped to the petcock of the blistering radiator. As the hot water poured into the bag, she could feel its coldness change to a tepid warmth. Hastily she ran back to Murray and poured the contents of the bag over his head and shoulders.
