A new type of rammer, intended for turret vessels, having hydraulic power, has been designed and designated as the hydro-pneumatic rammer. It is much simpler than the old type of hydraulic rammer, and much stronger. Four have been supplied to the Oregon, four to the Texas, and others are in process of manufacture to replace the old types of hydraubc rammers in service. New vessels will be supplied with a simple form of telescopic rammers capable of being operated by hand or by electric power. The use of electric power for turning turrets, hoisting ammunition, and operating gun-working machinery, which the Bureau has strongly advocated for some years past, has demonstrated its superiority over any other kind of power for these purposes, and the Department is to be congratulated upon its action in designating its use, in ships now building and to be built, to the extent it has. A simple expansion of the electric plant is sufficient to furnish the requisite power, and the facility of running cables, as compared with steam, pneumatic, or hydraulic pipes, the absence of heat, which causes so much discomfort in modern vessels, and the perfection of control and ease of manipulation of which it is susceptible render the electric system immeasurably preferable to any other which depends upon long leads of pipes under high pressure, with numerous packed pistons, valves, and Joints.
