Captain Riley's narrative of his shipwreck on the coast of Africa, and his captivity among the Arabs, was a book which my boy and his brother prized with a kind of personal interest, because their father told them that he had once seen a son of Captain Riley when he went to get his appointment of collector at Columbus, and that this son was named William Willshire Riley, after the good English merchant, William Willshire, who had ransomed Captain Riley. William Willshire seemed to them almost the best man who ever lived; though my boy had secretly a greater fondness for the Arab, Sidi Hamet, who was kind to Captain Riley and kept his brother Seid from ill-treating him whenever he could. Probably the boy liked him better because the Arab was more picturesque than the Englishman. The whole narrative was very interesting; it had a vein of sincere and earnest piety in it which was not its least charm, and it was written in a style of old-fashioned stateliness which was not without its effect with the boys. Somehow they did not think of the Arabs in this narrative as of the same race and faith with the Arabs of Bagdad and the other places in the _Arabian Nights_. They did not think whether these were Mohammedans or not; they naturalized them in the fairy world where all boys are citizens, and lived with them there upon the same familiar terms as they lived with Robinson Crusoe. Their father once told them that _Robinson Crusoe_ had robbed the real narrative of Alexander Selkirk of the place it ought to have held in the remembrance of the world; and my boy had a feeling of guilt in reading it, as if he were making himself the accomplice of an impostor. He liked the _Arabian Nights_, but oddly enough these wonderful tales made no such impression on his fancy as the stories in a wretchedly inferior book made. He did not know the name of this book, or who wrote it; from which I imagine that much of his reading was of the purblind sort that ignorant grown-up people do, without any sort of literary vision. He read this book perpetually, when he was not reading his _Greek and Roman Mythology_; and then suddenly, one day, as happens in childhood with so many things, it vanished out of his possession as if by magic. Perhaps he lost it; perhaps he lent it; at any rate it was gone, and he never got it back, and he never knew what book it was till thirty years afterward, when he picked up from a friend's library-table a copy of _Gesta Romanorum_, and recognized in this collection of old monkish legends the long-missing treasure of his boyhood.
