This collection consists primarily of letters exchanged between Edison and Secretary of the Navy Josephus Daniels, along with related correspondence. Many of the typewritten letters are accompanied by drafts in Edison's hand. The documents in this folder are from February-April 1917. They pertain to Edison's idea of attaching extension ladders, such as those used by the New York Fire Dept., to the tops of observing masts on warships. Photographs of the ladder are included with Edison's letters.
This project is described on p. 190 of Lloyd N. Scott's Naval Consulting Board of the United States.
