186 quarter there were launched 126 vessels' of 241,805 tons, and 4 sailers of 750 tons. At the same date there were under construction in the United Kingdom 77 warships of 303,685 tons displacement, including 70 vessels of 257,585 tons for the British Admiralty. The ships for foreign accounts included a_ battleship of 19,600 tons at Barrow, one of 19,000 tons at Elswick, two scouts of 6,000 tons at Elswick, and three torpedo boat destroyers of 1,800 tons at Scotstoun. In the Admiralty dockyards there were under construction two battleships of 42,- 400 tons displacements at Portsmouth, two armored cruisers of 39,750 tons at Devonport, two third-class cruisers of 6,700 tons at Pembroke, and four sub- marines of 1,880 tons at Chatham. In private yards the work included one battleship, 'each of 22,500 tons at Dalmuir and Elswick, and one each of 20,000 tons at Greenock and Jarrow, pro- tected cruisers, two each, of 10,050 tons at Barrow, Dalmuir, and Elswick, one each of 4,800 tons at Clydebank and Govan, and one of 5,250 tons at Govan; 40 torpedo destroyers as under: Govan (8), Clydebank (6), Woolston (5), Cowes (5), Hebburn (4), Dumbarton (4), Birkenhead (3), and one each at Blackwall, Govan, Jarrow, Partick and Wallsend, and seven submarines at Bar- row. A NEW GAS POWER TUG. A large gasoline towboat, designed for ocean service, has just gone into service for the Breakwater Co., which is build- ing a breakwater at Cape May. The boat, which is named the Natalie, was built by M. M. Davis & Son, of Solomons, Md., from plans by Capt. I. A. Watrous, of the Breakwater Co. The Natalie is 65 ft. on deck, 18 ft. beam and her least depth sof hold is 6 ft. 4 in. with a normal draught of 3% ft. By means of water ballast, her draught can be increased 12 in. Her frames are doubled, of sawed oak, 3% in. *by 8 in. and 22 in. centers. The deck beams are 8 x 8 in. spaced 22 in, centers. 12 in.; the keelson is 12 x 12 in. There are four sister keelsons, 8 x 8 in., and bilge stringers, 6 x 10 in. The shelf is '6 x, 10. in. This framing is as heavy as ordinarily employed for a 125-ft. steam tug, but with the Natalie strength is one of the features. She is planked with selected 2¥4-in. oak and sheathed inside with 3-in. yellow pine. Her deck is of oak and yellow pine laid in square. All fastenings are of galvan- ized iron and a large number of bolts -are used, The superstructure is of oak and pine The keel is of oak, 10 x strips 3). in. THE Marine REVIEW and the deck house is divided into three staterooms, a combination galley and mess room, two large storerooms for hawsers, etc., and a toilet room. Fresh water tanks with a total capac- May, 1919 windlass is deemed a necessity. An ex. tra large double bitt and windlass ig fitted forward while on each side of the deckhouse are fitted heavy iron bitig The electric plant engine also operates Gas Power Tuc NATALIE. ity of 15,000 gal. are fitted forward and aft, in which water will be carried for supplying the steam derricks em- ployed on the breakwater or for ballast. The gasoline tank, which is of No. 12 copper, with a capacity. of 600 gals., is stowed forward. It rests in a galvan- ized pan, having an outboard drip and with a vent pipe extending to the top of the pilot house. The main engine is of 125-H. P., of the four-cycle, reversible, Standard type, giving a speed of 12 miles per hour. An 8-H. P. Standard engine is connected to a 41%4-K. W. 110-volt generator for electric lighting, including cabin, deck and running lights and a 9-in. search- light, and current to two electric motors, one of which is for operating a 4-in. wrecking pump, equipped with 25 ft. of suction hose of a corresponding size. This pump can also be utilized for operating four lines of 2-in. fire hose, taking the supply from the sea or from the storage tanks, or for transfering fresh water to other vessels or shift it from the forward to the after tank or vice versa. The other motor referred to is used to operate a gypsy windlass on the after deck, a convenience fitted on com- paratively few of the large steam tugs, but since the crew of the Natalie will have to handle 8-in. hawsers the power an air pump for supplying compresseéd air for the 3%4-in. whistle. The ground tackle consists of two patent anchors of 500 and 300 lbs, re- spectively. In other respects, the gen- eral equipment of the Natalie is about the same as is found upon the average sea-going towboat. The work that the Natalie will do will be to handle 150-ft. barges laden with stone, etc, for the construction work on the new breakwater. While it will be deep sea towing for several miles, the roughest part of the work will be in towing the barges into the shoal water in heavy weather. It is expected that she will frequently ground on the bar and that on occasions she will have to go through the breakers. She has been built especially to with- stand strains of all kinds and she will do work that two steam tugs formerly did until they were both lost on the bar. The Skinner Shipbuilding Co., Balti- more, Md., launched the tug Lynn Haven for the Norfolk & Southern railroad last month. The Chesapeake Steamship Co., Balti- more, Md., are to build two passengef and freight steamers, 310 ft. long and 60 ft. over guards.
