Joseph, moreover, as he grew in years, had learned to read comprehensively, in. which qualification he was far in advance of his elder brother, and even of his father; and this talent was assiduously devoted as he quitted or modified his idle habits, to the perusal of works of fiction and records of criminality, such for instance as would be classed with the "dime novels" of the present day. The stories of Stephen Burroughs and Captain Kidd, and the like, presented the highest charms for his expanding mental perceptions. As he further advanced in reading and knowledge, he assumed a spiritual or religious turn of mind, and frequently perused the Bible, becoming quite familiar with portions thereof, both of the Old and New Testaments; selected texts from which he quoted and discussed with great assurance when in the presence of his superstitious acquaintances. The Prophecies and Revelations were his special forte. His interpretations of scriptural passages were always original and unique, and his deductions and conclusions often disgustingly blasphemous, according to the common apprehensions of Christian people.
