The stream dwindled slowly, imperceptibly.
One morning the prospector noticed it, and immediately explored the creek clear to its source--a spurt of water springing from the roof of a grotto in the cliff. Such a supply, evidently from the rocky heart of the range itself, would be inexhaustible.
A week later he awoke to find the creek-bed dry save in a few depressions among the rocks. He again visited the grotto. The place was damp and cool, glistening with beads of moisture, but the flow from the roof-crevice had ceased. Still he thought there must be plenty of water beneath the rocks of the stream-bed. He would dig for it.
Another week, and he became uneasy. The stream had disappeared as though poured into a colossal crevice. A few feet below the gravel he struck solid rock. He tried dynamite unsuccessfully. Then he hoarded the drippings from the grotto crevice till he had filled his canteen. Carefully he stowed his gold in a chamois pouch and prepared to leave the cañon. His burro had strayed during the week of drought--was probably dead beside some dry water-hole.
The prospector set out to cross the range in the light of the stars.
Fearful that he might be seen, panic warped his reasoning. He planned to journey south along the foothills, until opposite the desert town and then cross over to it. If he approached from such a direction, no one would guess his original starting-place. He knew of an unfailing water-hole two days' journey from the cañon. This water-hole was far out of his way, but his canteen supply would more than last till he reached it.
Then Fate, the fate that had dogged his every step since first he ventured into the solitudes, closed up and crept at his heels. He became more morose and strangely fearful. His vision, refined by the wasting of his body, created shadows that lay about his feet like stagnant pools, shadows where no shadows should be.
Ominous was his fall as he crossed an arroyo. The canteen, slung over his shoulder, struck a sharp point of rock that started one of the seams. The leak was infinitesimal. The felt cover of the canteen absorbed the drip, which evaporated. When he arrived at the water-hole, _that_ was dry. His canteen felt strangely light. He could not remember having used so much water. He changed his plan. He struck straight from the hills toward the railroad. He knew that eventually he would, as he journeyed west, cross it, perhaps near a water-tank.
