Frames, floors, keelsons, stringers, beams, sheer strake, bilge strake, strapping, keel plate, ete., are to be of steel; stem, sternpost, rudderpost, rudder, false keel, shoe, sheathing, gripe or stern and bilge keels to be of seasoned white oak; keel, planking, and dead wood to be of seasoned long-leaf Georgia or Florida pine. Fastenings in plank, keel, and. deadwood to be of galvanized iron; in the wood sheathing, composition spikes. The metal sheathing to be 26, 28 and 30-ounce metal, double-punched. The outfit is to include a steam windlass, steam hoister, three anchors, steam heating apparatus and well-ar- ranged quarters for crew that will involve quite an outlay in the general equipment. The main engine will be of the vertical inverted, suface-condensing type, with a single cylinder. All its parts must be proportioned to resist the strains due toa maximum working steam pressure of 100 pounds per square inch and 150 revolutions per minute for any duration of service .The steam cylinder will be 20 inches diam- eter, with 22 inches stroke ot piston. The electric lighting plant, which will include two of the General Electric Co.'s marine sets, with 5 by 4-inch double cylinder General Electric Co. engine, will be an im- portant item of expense in each of these vessels. About the only important item of freight in which there was a decrease during the past season was hard coal, which is moved prin- cipally from Buffalo to the northwest. Shipments from Buffalo dur- ing 1896 aggregated 2,400,068 net tons, according to custom house reports. This isa decline of 220,700 tons, compared with last year's shipments. Shipments from Buffalo by lake for the years named were as follows: 1896, 2,400,068 tons; 1895, 2,620,768 tons; 1894, SIDE ELEVATION PLAN OF NEW LIGHT-SHIPS, cient power to move them to and from their stations.
