The tenderfoot rose from the ledge upon which he had been lying and stretched himself stiffly. The chill of the long night had set him shivering. His bones ached from the pressure of his body upon the rock where he had slept and waked and dozed again with troubled dreams. The sharpness of his hunger made him light-headed. Thirst tortured him.
