ONE:Brewster mumbled out of a towel that he guessed they were all right, and implied what the dickens did it matter to him how they were.When he was well within, he began to investigate, and he recalled now that he had heard a great deal of this cave. It was very large, supposedly, but almost unexplored. Tradition ran that the Spaniards, in the long-past days of their occupation, had had a big silver mine in there, worked by padres who had taught the timid Indians to believe that it was haunted, that they might not take it for themselves, nor yet guide others to it. And, too, it had been the refuge and hiding-place of Billy the Kid for years. It was said that since then a corporal and three men had gone in once, and that a search party had found their gnawed skeletons by the edge of the river that flowed there underground. Oddly enough, and thanks to the missionary fathers, it had never served as an Indian stronghold, though its advantages for such a use were manifest.
