Memorial of the American Ordnance Company, relating to the armament of the fortifications, suggesting to Congress an improved system of ordnance, and proposing an economical, practical, and decisive series of experiments to test its value by firing guns of other most approved kinds in competition with them, to show the increase of power, endurance, range, precision, and general utility of the new kind over all others; showing, also, how a better armament for the fortifications may be procured, twice as powerful, and so much cheaper that $54,000,000 may be saved to the Treasury. The American Ordnance Company, by Norman Wiard, its Superintendent and General Agent, Washington.
