PETER THE GREAT.

ADMIRAL POPOFF. NOVGOROD.

Armored belt and barbette casemate, circular iron-clads. Six screws, no sail-power. The belt of these ships encloses the water-line to the height of the low freeboard. The deck has more than the ordinary spring, forming a sort of light glacis. In the centre of the vessel rises a circular barbette casemate, covering the carriages of two heavy guns mounted on a turn-table within it. Forward and aft the top of the casemate is continued in a musket-proof superstructure, having aft a musket-proof pilot-house. The forward section of the vessel is heavily strengthened for ramming. The two smoke-stacks are placed one either side of the casemate.

DOUBLE AND SINGLE TURRETED MONITORS.

These vessels are of the general type of the American monitors, with slight freeboard, great overhang, and double screws. The turret is raised somewhat higher than in the American monitors, and the foot is protected by a glacis. The turret is also somewhat larger, giving clear fire past the smoke-stacks. Pilot-house on top of the turret.
