The irresistiblelogic of eventshad at this time forced the displacement above tons; the water-line de-fense continued about the same. Few. if any. armored vessels with complete or partial water-line belts have these of suffleient depth to give proper protection when rolling. This defectis minimized, of course, in the large ships of from 13,000 to 15,000 tons displacement, which 36 ARMOR. were not found to roll appreciably in any sea-way that permitted ordinary vessels to worktheir guns. In the barbette ships there was greater freeboard at the ends, four heavy guns placed highabove water in two separate barbettes, and a central battery, containing an auxiliary arma-ment identical with that provided for in the turret ships. In the strength of the protectivearmor are the ammunition-tubes, and in the general protection of the loading arrangements a: I. anil gun-mountings the English type of barbette (Fig. 2) is held to bo far superior to that to befound in most foreign war-ships.
