A [NEW ;lake freight steamer. The general plan is shown in the accompanying sketch, fromthe Marine Atvit-u. A new feature in the boats, which are to be duplicates in allrespects, wiih the exception of probably a slight difference inthe proportion of engines, is the absence of sheer in their con-struction. They will be built without any sheer—that is, theywill be the same deptn at ends as in the middle, and the gun-wale will be a bevel line. In this there is said to be a savingof to $15,000 on boats of this class. The boats are tobe 275 ft. keel, 40 ft. beam and 26 ft. depth from base line totop of spar deck beams at side. The boats to be built by theGlobe Company, of Cleveland, and the Detroit Dry Dock Com-pany, will be engined Dy those companies ; but H. G. Trout &Company, of Buffalo, will build the engines for the steamer tobe built by the Union Dry Dock Company, and the Lake ErieBoiler Works, also of Buffalo, will build the boile
