THREE:What had he done with four and thirty years, putting it at the very highest valuation? He had sunk so far below the standard of his youth that he would not be fit for his old companions, even if he had wanted to go back to them, which, except in certain fits of depression, he did not. His own mother cared very little what became of him. At Christmas time she always sent him a letter, which reached him much later, as a rule, and he answered it. His brothers had forgotten him. His sister, of whom he had been very fond once, and for whom he had hoped a great deal, had married well enough and gone to London; but she, too, had forgotten him long since.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.
