This folder contains documents relating to an explosion in January 1916 aboard the Navy's E-2 submarine in the Brooklyn Navy Yard that resulted in the death of five men. The one item for 1917 is a 72-page report by consulting engineer Lamar Lyndon entitled Report on Edison Storage Batteries for Submarine Service, printed for the use of the U.S. Senate Committee on Naval Affairs and published by the Government Printing Office.
