Still's _Underground Railroad Records_, a large volume of 780 pages, appeared in 1872, and a second edition in 1883. For some years before the War Mr. Still was a clerk in the office of the Pennsylvania Anti-Slavery Society in Philadelphia; and from 1852 to 1860 he served as chairman of the Acting Vigilance Committee of Philadelphia, a body whose special business it was to harbor fugitives and help them towards Canada. About 1850 Mr. Still began to keep records of the stories he heard from runaways, and his book is mainly a compilation of these stories, together with some Underground Railroad correspondence. At the end there are some biographical sketches of persons more or less prominent in the anti-slavery cause. The book is a mine of material relating to the work of the Vigilance Committee of Philadelphia. Operations carried on in an extended field of six or seven counties in southeastern Pennsylvania, over routes many of which led to the Quaker City, are recounted in Smedley's volume of 395 pages, published in 1883. The abundant reminiscences and short biographies were patiently gathered by the author from many aged participants in underground enterprises. In his _Reminiscences_, a book of 732 pages, Levi Coffin, the reputed president of the Underground Railroad, relates his experiences from the time when he began, as a youth in North Carolina, to direct slaves northward on the path to liberty, till the time when, after twenty years of service in eastern Indiana and fifteen in Cincinnati, Ohio, he and his coworkers were relieved by the admission of slaves within the lines of the Union forces in the South. Mr. Coffin was a Quaker of the gentle but firm type depicted by Harriet Beecher Stowe in the character Simeon Halliday, of which he may have been the original. It need scarcely be said, therefore, that his autobiography is characterized by simplicity and candor, and supplies a fund of information in regard to those branches of the Road with which its author was connected. Pettit's _Sketches_ comprise a series of articles printed in the Fredonia (New York) _Censor_, during the fall of 1868, and collected in 1879 into a book of 174 pages. The author was for many years a "conductor" in southwestern New York, and most of the adventures narrated occurred within his personal knowledge.
