the wheels, were plated with two-or three-inch iron, according to the locality; the heaviest plating being on the forward end of the casemate. In the Tuscumbia this forward plating was six inches thick. The casemates were pierced with ports for all their guns at the forward end only; on each beam one port, and two aft. The ports were closed with two three-inch iron shutters which slid back on tracks on either side. In these casemates the Tuscumbia carried three XI-inch guns, the Indianola and Chillicothe each two XI-inch. In the two larger vessels there was also, between the wheels, a stern casemate seventeen feet long, built of thick oak, not armored on the forward end, but having two-inch plating aft and one-inch on each side. In this stern casemate, pointing aft and capable of being trained four points (45 deg.) on each quarter, the Tuscumbia carried two 100-pound rifles, and the Indianola two IX-inch guns. The hulls inside and abaft the wheels, and the decks, except inside the main casemate, were plated, but more lightly than the forward parts. In the Tuscumbia and Indianola, iron bulwarks, half an inch thick and pierced with loop-holes for musketry, extended all round the boats, except against the wheelhouses; they were so arranged as to let down on deck when desired. When ready for service, with guns and stores on board, these boats drew from five to seven feet of water; but they were so weakly built as to be dangerous and comparatively inefficient vessels, quickly "disabled," as is apt to be the case with such preparations for war as are postponed to the time of its outbreak. The contingency of civil war on our inland waters was not indeed to be anticipated nor prepared for; but what was the history of the ocean navy, on whose hasty creation such harmful boasts and confidence were and are based? They served their turn, for that enemy had no seamen, no navy, and few mechanics; but they were then swept from the list, rotten and broken down before their time. At this day nearly every ship that can carry the United States flag was built before the war or long after it.
