MARINE REVIEW. Roly Vel. CLEVELAND, OHIO, THURSDAY, DECEMBER cee OO2. No. 24. =< The Great Northern Steamships. Twenty-eight Belleville boilers and twin engines of the quad- ruple expansion type, using steam at 210 pounds absolute, will furnish power for the Great Northern passenger steamers, the hulls for two of which are now well under way at the ship yard of the Globe Iron Works Company, Cleveland. Definite ar- rangements regarding these powerful steam generators and latest type of engines were finally concluded this week, and the work of coustructing the two big steamships will now go for- ward very rapidly, although it is not expected that they will be ready for service until June, 1894. 'The cylinders of the twin engines are to be 25, 36, 51% and 74 inches by 42 inches stroke, and they are expected to develop 7,000 horse power. This short description of engines and boilers is enough to convince anyone, having even a slight knowledge of the class of boats now owned in this country, that the construction of these passenger ships will not only be far in advance of anything ever ~ attempted in the way of naval architecture on the lakes, but the boats will compare favorably with the best of sea-going passenger steamers. 'This latest decision as to power for these boats is, in itself, enough to show that Mr. James J. Hill, president of the SECM LO OEe OUOn LON Ooms OM Om o=O ahotonyone. eo 0 0} 6 00000900; 0 0 the most elegantly appointed steamships ever built to run on American waters. Mr. John Gordon, general manager, and Mr. I'. P. Carpen- ter, general passenger agent of the Northern Steamship Com- pany, together with Mr. Miers Coryell, who is agent in this country for the Belleville boiler, and whoas a naval engineer will represent the owners in the construction of the machinery, were all in Cleveland this week concluding the arrangements here re- ferred to. Mr. Gordon recognizes very thoroughly the great departure being made from previous practice in this country in the adoption of Belleville generators and quadruple expansion engines, but this is necessary on account of the power required to produce 20 miles an hour. 'The new Inman line steamers are to have quadruple expansion engines, and there is nothing ex- perimental in the use of the Belleville boiler. Although in use in a large number of big merchant steam- ers of France andin the French and Russian navy, some of them developing as high as 14,0o00-horse power, the application of Belleville boilers to marine purposes in this country has up to this time been confined to yachts and steam vessels of a limit of about 500 horse power. The boiler is, however, the only tubulous ~~ DLO Ose: OO n Om ae OOO ye A OO.

Great Merthern Railway, of which system the passenger boats will be a part, is sparing no effort to reach the speed of 20 miles an hour demanded for the lake service between Buffalo and Du- luth. 'There is no doubt that it is the ultimate intention of Mr. Hill to acquire for the lakes a fleet of six vessels all equal in every respect to the two now building, and all intended ex- clusively for passenger service, as the six boats of the Northern Steamship Company now in commission are used entirely for freight. Within another month the Great Northern Railway Line will have been completed to Everett on Puget Sound, and Mr. Hill and his associates are determined in their intention to eventually add to their system of railway and steamship lines across the American continent, a line of steamers on the Pacific, in competition with the present service of the Canadian Pacific Railway. The accompanying engraving will give a fair idea of the ap- pearance of these new lake steamships when completed. They are to be 360 feet keel, 380 feet over all, 44 feet beam and 34 feet deep. 'The apparent difference in the depth as compared with lake steamers is due to the fact that their sides will be built high up to the top of the cabins, alike to ocean- going steamers. Accommodations will be furnished in these boats for 316 cabin Passengers and 300 immigrants, and they will in all repects be boiler in use on merchant vessels of large size, and in its applica- tion to these lake vessels a big advantage will undoubtedly be found in the fresh water. Among the latest French merchant steamers fitted with these boilers are the Australien, Polynesien and Tasmanien of the Mes- sageries Maritime Company, which company builds its own steamships and controls more vessel property than any other company in France. The boats are engaged in passenger and freight service between Marseille and Sidney, N.S. W., and are 502 feet long, with a gross displacement of 8,638 tons. They have triple expansion engines, with cylinders 44, .67 and 106 inches diameter by 54 inches stroke, developing 7,650 horse power. These dimensions of the vessels and machinety* will serve to show the class of steamers to which the Belleville. gen- erators have already beeen fitted. hee While running in open water on Lakes Erie, Huron caxmit Su-. 'perior these lake greyhounds will draw about 18 feet of water. This draft, to be secured by water ballast, is necessary to the re- quired speed and will also be a great factor of safety and comfort to passengers in heavy weather. The facilities for filling and discharging water compartments will be such that on leaving Buf- falo the vessel can be lowered in the water, raised again on reach- ing the rivers and the draught increased again on upper lakes.
