His face was deep-lined with distress as he sat by the camp-fire, trying in vain to moisten his lips with his dry tongue. One picture after another arose before him: streams of crystal water which he had forded; icy mountain springs at which he had knelt and drank; deep wells from which he had thrown whole bucketfuls away after he had quenched what he then called thirst. Thirst! He never had known thirst. What he had called thirst was laughable in comparison with this awful longing, this madness, this desire beside which all else paled. In any other than an alkali country, the lack of water for the same length of time would have meant little more than discomfort, but the parching, drying effect of the deadly white dust entailed untold suffering upon the traveller caught unprepared as was Smith. He rolled and smoked innumerable cigarettes, rising at intervals to pace restlessly to and fro. His lips and tongue were so parched that both taste and feeling seemed deadened. Had he not seen the smoke, it is doubtful if he could have been sure he was smoking. He wandered away from the fire after a time, walking aimlessly, having no objective point. He desired only to be moving. Something like a half-mile from his camp he came into a shallow cut which appeared to have been made during bygone rainy seasons, but which now bore no evidence of having carried water for many years. He followed it mechanically, stumbling awkwardly in his high-heeled cowboy boots over the rocks which had washed into its bed from the alkali-coated sides. Suddenly he cried aloud, with a shrill, penetrating cry that was peculiar to him when surprised or startled. He had inadvertently kicked up a rock which showed moisture beneath it! He began to run, with his mouth open, his bloodshot eyes wide and staring. There was a bare chance that it might come from one of those desert springs which appear and disappear at irregular intervals in the sand. As he ran, he saw hoof-tracks in what had once been mud, and his heart beat higher with hope. He had a thought in his half-crazed brain that the water might disappear before he could reach it, and he ran like one frenzied with fear. The world was swimming around him, his heart was pounding in his breast, yet still he stumbled on at top speed. [Illustration: IT MEANT DEATH--BUT IT WAS WET!--IT WAS WATER!] The cut grew deeper, and indications of moisture increased. He saw a growth of large sage-brush, then a clump or two of rank, saw-edged grass. These things meant water! He turned a bend and there, beneath a high bank, was a pool crusted to the edge with alkali!
