The Museum of ordnance and trophies exhibits all the various progressive stages in the manufacture of swords, muskets, cartridges, powder, and shot; models of field and siege guns, and the anatomical structure of horses for instruction in the department of cavalry. The collection of ancient and experimental weapons; of Rebel torpedoes, and Rebel shot from many battle-fields; of flag-staffs and flags from Mexico; Indian trophies and curious projectiles, and the numerous flags borne by the regular army in the last war with England, in the Florida war, in Mexico, and in the Rebellion, with their inscriptions, excites a degree of interest which cannot be overcome by a momentary glance.
