At the age of 20 he went to Philadelphia, where he engaged in literary enterprises, and at the time of his death was proprietor and editor of the "Philadelphia Gazette." He had furnished to the "Knickerbocker " a series of contributions under the title of "Ollapodiana," which with others of his works were collected and published in 1844, and again in 1847.
