Perry of San Francisco, a self-propelling single- screw suction dredge named Atlantic for use in Galveston harbor. The dredge is 160 ft. 8 in. over all, 30 ft. beam, 14 ft. deep, and has a draught of 7 ft. 6 in. Her engines are triple-expansion, 18.30 and 48 in. in diameter by 20 in. stroke, built by the Great Lakes Engineering Works, Detroit, Mich. Her boilers are of the Heine water-tube type, built by the Risdon Iron Works, San Francisco. The dredge is to be fitted with a raised forecastle deck, under which will be the blacksmith shop, storerooms and toilet rooms. The crew space on the port side will be forward under the main deck, with hold abaft. The crew space on the starboard side for- ward will have the cutter engine room abaft of it. There will be two chain lockers abaft of the collision bulkhead and at the for- ward end of the boiler room a cross bunker will extend the full breadth of the ship, 12 ft. fore and aft. A portable bow is fitted, filling the forward end of well. - At the aft end of the engine room a shaft tunnel will be arranged under watertight flat, extending from aft of engine room bulkhead to stern frame. A peak tank is fitted aft and on each side forward of the collision bulkhead. A. steel super- {Jan. 21, tions for twenty-one first-class passengers are all on the poop deck. On the bridge deck are placed the pilot house and cap- tain's rooms. a : The main engines are 13 and 28 in. in diameter by 21 in. stroke, indicating 300 H. P. at 130 revolutions and designed fora speed of 914 knots an hour on 6 tons of coal. The boiler is 10 ft. 1o in. in diameter by 11 ft. 1 in. long, allowed 150 Ibs. working pressure aid equipped with two 42-in. Morison suspension fur- naces. The steamer is built for special trade and requires extra heavy fittings. The hull is double plated from forecastle deck to keel in wake of anchor for' about 12 ft. back from the bow. The stem is also protected by a 7-16-in. steel shoe from 2 ft. above load line to 14 ft. after the perpendicular. This is to protect the wear of the anchor chains on the stem, for, as a matter of fact, in this trade a set of hawser pipes will wear out in two years. The steamer is fitted with electric lights throughout, including the mast head, side and riding lights. The vessel carries three car- go boats of about 380 cu. ft. capacity each. These boats are hoist- ed by steam, as are also all the sails. An anchor windlass is also provided to take in both chains, 90 fathoms each, at the same time in two structure extends from bulkheads 12 iG 46, 20. ft 1 ifr in breadth, con- taining engine and boiler casings, of- ficefs quartets, mess room and bath room, galley, pantry, crews' lav- atories, mach ine shop and hoisting winch room. The steel pilot house occupies the for- ward end of the 'Superstruc { UW rc. Two spuds are ar- ranged aft, pass- ing through the vessel will be rigg- ed with one pole mast and cargo boom. The gener- al scantlings and quality of the steel hull and wood decks conform to the rules and reg- ulations of Lloyd's © register of ship- ping. The suction pump is located in the engine room and is driven by minutes. The ves- sel is built to the highest class under Bureau Veritas for single-deck vessels, being constructed under special sur- vey for special ser- vices, MARINE RAILWAY. At Sault Ste. Martie. Mich. Hickler Bros., who have a ship yard of moderate pro- portions, recently put in one of the improved Crandall railway dry docks. It is especially suited to the kind of work that is done at the Sault and was erected by the H. 1. Crandall & Son Co., engi- neers and contrac- tors of East Bos- ton, Mass.. This railway dry dock has a capacity of 1,000 tons, dead- weight. It is con- structed of timber and is. of the three- the propelling ma- chinery. The suc- tion and discharge Pipes are 26 in. in- side diameter and 34 in. thick, fitted on port side with ladder well, leading to the pump in the forward end of engine room. The pipes lead througli the engine room and crew space and thence through the outside plating, port and starboard. The dredge is supplied with telegraphs from bridge to engine room and is equip- ed with electric call belis connected with all rooms. A steam capstan 's provided for handling the anchors. STEAMER LIKELIKE FOR HAWAIIAN TRADE. The Union Iron Works, San Francisco, is building a steamer of an interesting type for the Wilder Steamship Co. of Honolulu, to be named the Likelike. The steamer will be of steel, 136 ft. long, 30 ft. beam and 12 ft. 6 in. deep, and will be schooner rigged with two masts. From aft 80 ft. forward are included the poop and bridge decks. This arrangement furnishes accommodations for the officers and saloon for the cabin passengers, and also fur- nishes 'housings for the engines, boilers and galley From the poop deck to the forward end of bridge deck on each side of engine and boiler fidleys there is an enclosed passage, in which are placed firemen's quarters on the port side adjacent to the engine room, and on the starboard side are the ice house and toilet rooms. In these passages, exclusive of the accommoda- tions mentioned, is a deck laid for the convenience of deck pas- sengers. The main deck forward has carrying capacity for 150,000 ft. of lumber. The same space can be utilized for the carrying of heavy machinery, the main deck being amply braced for this purpose and the foremast being fitted as a derrick to lift heavy cargo, with steam cargo winch of double cylinder type in close connection to the main hatch. The forecastle is of the half- sunk type with accommodations for eighteen seamen. Placed on top of the forecastle is a horizontal, double-cylinder, geared wind- lass, fitted with large gypsy ends and wildcats for anchor chains. The vessel has but one hold and that is forward with one hatch and has a capacity of 400 tons below decks, with bunkers on each side of the boiler containing 31 tons each. Cabin accommoda- i ; | } track type. The SUCTION DREDGE ATLANTIC FOR R. A. PERRY, OF SAN FRANCISCO. Ctadie is 180 'ft. [Butlt by the New York Ship Building Co., Camden, N./. over keel blocks, 50 ft. wide, and is equipped with ten bilge blocks on each side, which are moved in and out by individual winches, operated from the platforms which extend the length of the cradle. The cradle is operated by es- pecially-constructed, marine railway chains of the highest grade. A vessel of the full capacity may be hauled smoothly and readily in twenty minutes from the time it is centered on the keel blocks, which is a strong point in favor of this form of dry dock. The dock has, been in operation since September last and has proven very satisfactory in all respects. VESSELS FOR THE LIGHTHOUSE DEPARTMENT. The lighthouse board is now designing a lighthouse tender for St. Mary's river (eleventh lighthouse district) and a relief light vessel to be stationed at the lighthouse depot, Charlevoix, Mich., which is in the ninth district. Bids for the construction of these vessels will be solicited shortly. In addition the following vessels are now under construction for the lighthouse board: Light- house tender Ivy for the seventh district and lighthouse tender Magnolia for the eighth district, both being built by the Baltimore Ship Building & Dry Dock Co., Baltimore, Md. The New York Ship Building Co., Camden, N. J., has under construction five light vessels as follows: Relief light vessel No. 78 for the third district; light vessel No. 79 for Five Fathoms' bank, N. J., fourth district ; light vessel No, 80 for Cape Lookout shoals, North Caro- lina, fifth district; light vessel No. 81 for Heald bank, Texas, eighth district light vessel No. 83 for Blunt's reef, Pacific ocean off Cape Mendocino, Cal., twelfth district. The 'Townsend-Downey Ship Building Co., Shooter's island New. York, is building the lighthouse tender Crocus for the tenth district, which includes Lakes Erie and Ontario. The Burlee Dry Dock Co., Port Richmond, N. Y.,, is building light vessel No. 76, to be stationed at the lighthouse depot, Tongue Point, Ore., for the thirteenth district. : :
