This folder contains correspondence and other documents concerning Edison's friendship and collaboration with industrialist Henry Ford. Many of the documents pertain to their lobbying efforts on behalf of the Weeks-McLean Migratory Bird Act, establishing hunting zones and seasons for migratory birds in the United States—a campaign that was also supported by Edison's wife, Mina Miller Edison. Also included are items relating to vacation plans involving Edison, Ford, and naturalist John Burroughs. In addition to Edison and Ford, the correspondents include William G. Bee of the Edison Storage Battery Co.; Ernest G. Liebold, Ford's personal secretary; and congressmen Champ Clark, Edward W. Townsend, and John W. Weeks.

Approximately 90 percent of the documents have been selected. The material not selected consists of unsolicited correspondence, mainly concerning Edison's celebrated friendship with Ford.
