206 very favorable net tonnage in relation to their deadweight. It will be seen from Fig. 1, that there are five cargo holds, each provided with a hatchway 35 ft. wide by more than 40 ft. long. The hatchways on the shelter deck have steel covers, while the corres- ponding openings on the upper deck have wood covers. Deep frames of channel section, spaced 37 in. apart for the greater part of the length, sup- port the side plating. In conformity with the latest practice for transverse- framed cargo ships, no side stringers are fitted, and the double bottom floors are placed at alternate frames. Deep vertical web girders are arranged on each side of the transverse bulk- heads in line with the wing ballast tank sides and similar webs are fitted at the center line, all these webs having large knees at the top and bottom. The top knees of the center webs support the pillars which carry the end coamings of the shelter deck hatchways. The loading and discharging appli- ances consist, at each hatchway, of two. derricks, each capable of lifting 5 tons, and two 7 x 12-in. winches, so -that there are 10 derricks and 10 winches altogether for cargo work, while an extra 7 x 12-in. winch is pro- vided aft for warping purposes. The | derricks of the two foremost and the two aftermost holds are supported from the masts, while those at the midship hold are supported by der- rick posts. Two of the ventilators to each hold are utilized to provide ac- cess to the portion below the upper deck, and on this account are made 27-in. diameter. The saloon and captain's accommo- dation is arranged in a deckhouse, 20 ft. long by 36 ft. wide situated on the shelter deck between the hatchways to Nos. 2 and 3 holds. On top of this house is placed the chart and wheel- house. The officers and engineers are accommodated in steel houses ar- ranged at the sides of the engine casing. The crew are berthed aft in the after end of the shelter 'tween decks. The propelling machinery in each vessel consists of one set of triple-" expansion engines having cylinders | 2844, 47° and 78 in., by 54-in. stroke, and driving a single screw. The boil- ers are of the ordinary cylindrical multitubular type. The engines and boilers were also built by Messrs. Wm. Doxford & Sons, Ltd. The Newburgh & Fishkill Ferry Co. has given contract to the I. S. Marvel Ship Building Co., Newburgh, N. Y., for a ferry boat to be a duplicate of the Duchess now in service.
