Early in the summer of 1863 Rev. William G. Scandlin was sent to the Army of the Potomac as the agent of the Association. Taken prisoner in July, he spent several months in Libby prison, where he was kindly treated and exercised a beneficent influence. He was followed in this work by Rev. William M. Mellen, who established a library of 3,000 volumes at the convalescent camp, Alexandria, and also distributed a large amount of reading matter in the army. Rev. Charles Lowe served for several months as chaplain in the camp of drafted men on Long Island, his salary being paid by the Association. In November, 1864, he made a tour of inspection, as the agent of the Association, to the hospitals of Philadelphia, Baltimore Annapolis, Washington, Alexandria, Fortress Monroe, City Point, and the Army of the Potomac, in order to arrange for the proper distribution of reading matter and for such other hospital service as could be rendered. More than 3,000 volumes of the publications of the Association were distributed to the soldiers and in the hospitals, largely by Rev. J.G. Forman, of St. Louis, and Rev. John H. Heywood, of Louisville. Among those who acted as agents of the Association in furnishing reading to the army and hospitals were Rev. Calvin Stebbins, Rev. Frederick W. Holland, Rev. Benjamin H. Bailey, Rev. Artemas B. Muzzey, Rev. Newton M. Mann, and Mr. Henry G. Denny. Rev. Samuel Abbot Smith worked zealously at Norfolk at the hospitals and in preaching to the soldiers, until disease and death brought his labors to a close. What this kind of work was, and what it accomplished, was described by Louisa Alcott in her Hospital Sketches, and by William Howell Reed in his Hospital Life in the Army of the Potomac.
