This folder contains correspondence and other documents relating to telegraphy. Included are letters seeking Edison's opinions about technological developments and his advice on technical matters, along with items regarding his subscriptions to telegraphic services. Among the documents for 1912 are numerous letters to and from Edison's attorney Frederick J. Stone pertaining to the protracted litigation against Jay Gould and the Atlantic & Pacific Telegraph Co., which was initiated during the 1870s by Edison, George Harrington, and Josiah C. Reiff. (Related material for 1911 and 1913 can be found in the "Legal -- Litigation" folders in the Edison General File Series.) Also included is correspondence with Newcomb Carlton, vice president of Western Union, concerning the use of phonographs in telegraphic operations.

Approximately 70 percent of the documents have been selected. The unselected material consists primarily of circulars, letters of transmittal and acknowledgment, and unsolicited correspondence seeking advice or information. Some of the items bear perfunctory replies, written by Edison in the form of marginalia.
