A BOAT FOR WINTER NAVIGATION. - The following is a description of the proposed mail boat which is to this winter on the St. Lawrence River: "Length over all, 153 feet; breadth of beam, 23 feet, 8 inches; depth of hold, 16 feet. She has a very high rise of floor; a boy's top split vertically would give a good idea of the form of her midship section; such a form secures the hull from any right angle pressure, thus reducing the pressure of the ice to a minimum. The stem is well-rounded at the lower point so as to secure riding in heavy ice - that is to say, a driving of the vessel's forward part into the ice, thus crushing it down and relieving the vessel by displacing the ice at three points, viz: on each bow and under the forefoot. The iron plating for the protection of the hull is composed of 700 bars of 4x7/8 inch flat iron, reaching from two feet above the level water line to within four feet of the keel. She is fitted with engines of 700 horse-power indicature; they are of compressed build, and fitted with a surface condenser. Steam is carried through pipes to the heating apparatus in the saloons, and such parts of the vessel where required. All the lights (i.e. windows) in the cabins, saloons and steering-house are well forward, so as to serve as wheel-house and lookout house - a great desideratum while coming through ice. A spar deck runs from end to end, securing warmth and shelter to the crew. The screw propeller is 11 feet, 6 inches in diameter, with a pitch of 17 feet, and will at all times have three feet of water above the blade as a protection against ice.
