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-March 1917. They pertain to Edison's efforts to develop a method for extinguishing coak-bunker fires on warships.
This project is described on p. 186 of Lloyd N. Scott's Naval Consulting Board of the United States. Two photographs related to this report, bearing dates of February 9, 1917, appear opposite p. 186.
