These five notebooks were used by Selden G. Warner during 1917-1918 for notes on experiments performed for the U.S. Navy. The first book describes tests of various hydrogen detection devices. The remaining books relate primarily to a toothed wheel designed to cut through barbed wire in enemy trenches and to carry explosives. Included are notes on the wheel's construction, release, inertia, and other properties. Also included are experiments to determine the feasibility of using the wheel in connection with a new type of short-range, high-power projectile. In addition, there are experiments on an explosive concussion device and on the use of a kite for bomb delivery.
