This folder contains correspondence from Josiah C. Reiff, a longtime Edison associate who was involved in protracted litigation (George Harrington, Josiah C. Reiff, and Thomas A. Edison v. Atlantic and Pacific Telegraph Co. et al.) arising from Edison's telegraph work during the 1870s. Included are letters concerning Edison's involvement in the case and a copy of the agreement of December 30, 1874, between Reiff and Jay Gould.

Approximately 40 percent of the documents have been selected. The unselected items consist of scattered court records and letters discussing the progress of the litigation but not involving Edison directly.
