Edison was always a great reader, and was in the habit of buying books at auctions and second-hand stores. One day at an auction he bought twenty unbound volumes of the _North American Review_ for two dollars. These he had bound and delivered at the telegraph office. One morning, about three o'clock, he started off for home at a rapid pace with ten volumes on his shoulder. Very soon he became conscious of the fact that bullets were flying around him. He stopped, and a breathless policeman came up and seized him as a suspicious character, ordering him to drop his parcel and explain matters. Opening the package, he showed the books, somewhat to the disgust of the officer, who imagined he had caught a burglar sneaking away with his booty. Edison explained that, being deaf, he had heard no challenge, and therefore had kept moving; and the policeman remarked, apologetically, it was well for Edison he was not a better shot. Through all his travels Edison has preserved these books, and he has them now in his library at Llewelyn Park, Orange, New Jersey. After two years at Louisville, Edison went back North as far as Detroit, but soon returned to Louisville. At this time there was a great deal of exaggerated talk and report about the sunny life and easy wealth of South America. This idea appealed especially to telegraph operators, and young Edison, with his fertile imagination, was readily inflamed with the glowing idea of these great possibilities. Once more he threw up his work, and, with a couple of young friends, made his way to New Orleans, where they expected to catch a specially chartered steamer for Brazil. They arrived in New Orleans just at the time of the great riot, when the city was in the hands of a mob. The government had seized the steamer for carrying troops. The young men therefore visited another shipping office to make inquiries about vessels for Brazil. Here they got into conversation with an old Spaniard, to whom they explained their intentions. He had lived and worked in South America, and was very emphatic in advising them that the worst thing they could do was to leave the United States, whose freedom, calm, and opportunities could not be equaled anywhere on the face of the globe. Edison took the Spaniard's advice, and made his way North again. He heard later that his two companions had gone to Vera Cruz and had died there of yellow fever. He returned to Louisville and resumed work there. He seems to have been fairly comfortable and happy at this time. He surrounded himself with books and various apparatus, and even indited a treatise on electricity.
