r. Over the part of thevessel so defended against horizontal fire there is also anarmored steel deck, built up of two thicknesses of ^ in.plating and one layer 2 in. thick, making 3 iji. in all. Be-low the midship protective deck there is placed over theengines and boilers a light steel splinter deck, f in. thick,to prevent interference with the forced draft and shut itoff. Across the ends of the citadel are bulkheads of 18 in.and 16 in. armor. The sides of the ship above the upperdeck, where the auxiliary batteries are placed, are of steel,only I in. thick. The sloping ends of this battery are,however, armored with 6 in. plate, to prevent a rakingfire. This is the one fatal weakness of the Bcnboit., andof all her class. The 1 in. plate is just sufficient to ex-plode a shell charged with high explosive, so that it willdischarge its contents between decks, with what result can 358 THE RAILROAD AND (August, 1889. mmmmmiiiiiiiaiiiMMiiaj IUilllllIII l .^ Tl7Wiirii«Ill)l)IHI • ma ■\;i

When the coal bunkers alongthe sides of the ship below the armored deck are filledthey oppose a thickness of about 9 ft. of coal to the pas-sage of shot. On the lower deck, in front of the horizontalwater chamber—introduced to check the rolling of the shipby the movements of a large weight of water freely llowingfrom side to side—there are four deep water-tight tanks,to hold the ships cables. The two barbettes each cover a space on the upper deckabout 45 ft. by 60 ft., the plan being pear-shaped, so as toleave room for the protection of the loading gear. Theyhave steel-faced armor, 14 in. thick upon the exposedportions, and 13 in. thick behind the screens. An armoredammunition trunk, before mentioned, 10 ft. across, plated12 in. thick, provides for the safe lifting of the powder andshot from
