Williams Cache lies in the form of a great horn, with a narrow entrance at the lower end known as the Door, and a rock fissure at the upper end leading into Canadian Pass; but this fissure is so narrow that a man with a rifle could withstand a regiment. For a hundred miles east and west rise the granite walls of the Mission range, broken nowhere save by the formation known as the Cache. Even this does not penetrate the range; it is a pocket, and runs not over half-way into it and out again. But no man really knows the Cache; the most that may be said is that the main valley is known, and it is known as the roughest mountain fissure between the Spanish Sinks and the Mantrap country. Williams Cache lies between walls two thousand feet high, and within it is a small labyrinth of canyons. A generation ago, when Medicine Bend for one winter was the terminus of the overland railroad, vigilantes mercilessly cleaned out the town, and the few outlaws that escaped the shotgun and the noose at Medicine Bend found refuge in a far-away and unknown mountain gorge once named by French trappers the Cache. Years after these outcasts had come to infest it came one desperado more ferocious than all that had gone before. He made a frontier retreat of the Cache, and left to it the legacy of his evil name, Williams. Since his day it has served, as it served before, for the haunt of outlawed men. No honest man lives in Williams Cache, and few men of any sort live there long, since their lives are lives of violence; neither the law nor a woman crosses Deep Creek. But from the day of Williams to this day the Cache has had its ruler, and when Whispering Smith rode with a little party through the Door into the Cache the morning after the murder in Mission Valley he sent an envoy to Rebstock, whose success as a cattle-thief had brought its inevitable penalty. It had made Rebstock a man of consequence and of property and a man subject to the anxieties and annoyances of such responsibility.
