Centerville, October 21, 1861.
SECRETARY OF WAR:
SIR; Having heard some time since of the arrest by the enemy of an individual on whose person were found plans for the destruction of the enemy's ships of war, I through that it might be possible to replace by others these plans, and although I can scarcely hope to have invented an apparatus that possesses equal merits with that gentleman's, still I have so far succeeded in my own mind as to induce me to write to you on the subject. I have invented an instrument of war which for a better name I have called a submarine gun-boat. In many of its details I have not hesitated to adopt the plans of others, believing it far better to use machinery that has been found to be useful than to try to make a perfectly novel boat. I have thus greatly reduced the chances of a failure. As I have endeavored to avoid all chimerical plans, no one can consistently call me a visionary. In fact, my gun-boat can hardly be called the work of an inventor but rather that of mechanic, so little is there in it that has not been used before in some form or other. My plan is simple. A vessel is built of boiler iron of about fifty tons burden, similar to Winans' cigar steamer, but made of an oval form with the propeller behind. This is for the purpose of having as little draft of water as possible for the purpose of passing over sand-bars without being observed by the enemy. The engines are of the latest and best style so as to use as little steam as possible in proportion to the power received. The boilers are so constructed as to generate steam without a supply of air. The air for respiration is kept in a fit condition for breathing by
