As an example of the keen scent of the burro for water may be related the experience of two prospectors named Peterson and Kelley, who a few years ago attempted to cross the Great Mojave Desert on foot. They had with them, to carry their supplies, a burro. In passing from oasis to oasis they lost their way and the supply of water became exhausted. To be lost in the desert is a terrible thing, and the anxiety, coupled with the torturing thirst and the intense heat, drove Peterson insane. He left his companion and fled shrieking across the plain. Kelley picketed the burro and went after Peterson to bring him back, but he was unable to overtake him. He returned to the trail to find that his burro had broken his tether and was moving across the desert at a leisurely pace. He followed, but the animal was so far in the lead, and he was so exhausted from his efforts to overtake Peterson, that he could not come up to him. [Illustration: BEARING THE REDMAN'S BURDEN From photograph by C. C. Pierce & Co.] Night came upon him, and it soon became so dark that he could not distinguish the burro and he had to follow him by the footprints in the sand. When it became too dark to distinguish them he still staggered on in sheer desperation. By and by his heart gave a great throb. Before him, outlined against the sky and seemingly suspended in the air, was a form which he knew to be either his burro or an apparition. He hurried forward and lo! standing upon a sharp rise of ground and facing him was his lost burro, who seemed to be awaiting him for a purpose, for when he came up to him the animal turned and led the way down the incline to a spring of living water. Kelley gave a shout of joy and plunged bodily into the spring. After he had soaked his parched skin and moistened his lips and throat, he crawled out and went to his burro, which was browsing upon the green herbs growing about the place. Throwing his arms about the neck of the animal he gave the creature a hearty hug and a kiss. If this mark of affection surprised or touched the burro he made no sign. He merely nipped another mouthful of the herbage and continued chewing. When Kelley had taken a fresh supply of water he retraced his steps to the point where the burro had broken away. It was fully ten miles. There is no doubt but the animal had scented the water all that distance, and his eagerness to get to it had led him to strain at his fastenings till he broke loose. Poor Peterson did not survive. Kelley found his dead body the next morning four or five miles from the point where he had left the trail.
