The machinery will consist of a 4- cylinder, triple-expansion, surface con- densing engine, and will have cylin- ders 24%-in., 40, 47 and 47-in. diame- ter by 42-in. stroke. These steamers will also be equipped with their own refrigerating plant, thus affording cold storage facilities for taking care of dairy products, as well as refrigerating all supplies for their-own use. Special attention has been given in drawing plans and _ specifications to every facility for a prompt and careful handling of all freight cargo. The steamers will carry 650 tons of high class merchandise freight. COMBINATION ENGINES. Having passed beyond the experiment- al stage, the employment of combination engines for long voyage passenger liners continues to make headway. Curiously enough, it is in vessels engaged in trad- ing between England and Australasia that the adoption of this type of engines is most in evidence. The latest Orient liner to be built on the Clyde will have duplicate sets of reciprocating en- gines for her wing propellers, with a low-pressure turbine for her midships screw. In this respect she will be sim- ilar to the 12,000-ton liner Demosthenes, which the Aberdeen-White Star Line will place in their London-Australian service about April of next year. The New Zealand Shipping Co. has the credit of being pioneers in this re- spect, so far as the Australian and New Zealand trade is. concerned. About a year ago, their cargo. vessel Otaki, which has combination engines, made her maid- en voyage to New Zealand ports. Built July, 1910 torua, is engined on the same lines as the Otaki. The promise is that for liners not needing a very high speed, combination engines will find increasing favor. THE MACHINERY OF NEW BRITISH WARSHIPS. The six special torpedo boat destroy- ers just ordered by the British Ad- miralty will prove exceedingly interest- ing craft from an engineering point of view, and their sea performances will be awaited with deep interest. The two vessels entrusted to the Parsons Marine Steam Turbine Co., the hulls of which will be constructed by Messrs. William Denny Bros., Dumbarton, it is reported, will be propelled by Parsons geared tur- bines; the two to be built by Messrs. Yarrow & Co., Scotstown, will be fitted with Brown-Curtis turbines, and the re- midining.<two,eiven to Messrs. J. "I. Thornycroft & Co., Southampton, will be propelled by Parsons turbines driving twin screws. The contracting firms are given a perfectly free hand in the de- sign and construction of the propelling machinery, and as a result of this call- ing to their aid the technical skill and experience of these famous torpedo craft constructors, it is not unlikely that the idles STUYVESANT Docks, THE PRIVATE MARINE TERMINALS OF THE ILLINOIS CENTRAL System, Stx Mires Asove THE City FRONT. as she was on similar lines to one of the company's full-powered steamers possess- ing the ordinary type of reciprocating engines, the owners were able very ac curately to draw comparisons between the performances of the two types. That the New Zealand Shipping Co. is satis- fied as to the advantages of combina- tion engines is proved by the fact that their latest passenger Steamer, the Ro- Admiralty will succeed in improving the efficiency of the destroyer. The T. S. Marvel Shipbuilding Co., Newburgh, N. Y., has been awarded the contract for the hull and carpenter work of the new sidewheel steamer for the Catskill Evening Line, which will be 285 ft. long over all, 66 ft. beam over guards, and 12% ft. deep.
