The Motor Ship of September 26, 1912 published a list of 32 vessels then under con- 

 struction in which heavy oil (Diesel) engines were being fitted, the aggregate H.P. being 

 59,600 and average 1870; 17 were single-acting, four-stroke reversible; 9 were single- 

 acting two-stroke reversible; three were of Junker's type; two were single-acting four- 

 stroke non-reversible; and one only double-acting, a two stroke M.A.N. engine for a 

 Woermann liner by Messrs. Blohm and Voss (See Engineer, October u, 1912). The 

 non-reversing engines are for the " Tynemount " (see Mavor, Brit. Assoc., 1911 and 

 1912) of 600 H.P., and 9 knots, having electric transmission gear giving 80 revolutions of 

 the propeller for 400 revs, of the engines, and a shallow draught vessel of 1,300 H.P. for 

 service on the Congo, in which the engines run at 280 revs, and Fottinger transformers 

 are fitted to drive the propellers at 440 revs., giving the boat a speed of 15^ knots. The 

 largest engines named are of 6,000 H.P., and are for a twin screw vessel of 8,000 tons gross 

 and 1 6 knots speed to be built by Barclay, Curie & Co. 



Motors of various powers have been fitted as auxiliaries in numbers of sailing vessels; 

 the large French sailing vessel "France," of 6,500 tons D. W. capacity, has I.C. en- 

 gines of i, 800 H.P. and twin screws for 10 knots. Motors are being fitted in rapidly 

 increasing numbers of river steamers (see Syren and Shipping, August 21, 1912), river 

 tugs (see Motor Boat, March g, 1911), lifeboats (see Int. Com. Eng., October 2, 1912), 

 fishing craft of all descriptions (see Report of Fishery Board for Scotland, 1912), as well 

 as in small coasting vessels, of which eighteen are being built in Scotland for one firm 

 the Coasting Motor Shipping Co. Lloyd's Register of 1912 includes 61 yachts of 3,733 

 tons having I.C. engines, and indicates a falling off in the building of large steam yachts.

 Diesel Engines of various types :-*-

Notes, (i) First motor ship to cross the Atlantic, built by Swan, Hunter & Co. for Canadian 

 Lakes; Polar (Swedish) engines; estimated saving on machinery, 60 tons; fuel about 2 tons 

 a day instead of 8 (see also Engineering, May 5, 1911; similar engines 520 H.P. in Calgary, 

 and 1600 H. P. in tanker building by Calcdon Co.) (2) First seagoing motor vessel 

 regularly employed in European waters, built in Holland for Anglo-Saxon Petroleum Co. 

 Werkspoor (Dutch) engines. (Larger engines of same type in "Juno," " Emanuel Nobel," 

 " Louden, 1 ' " Eburna" and " Jules Henry;" and smaller in " Sembilan," "San Antonio "and 

 "Cornells "). (3) First large ocean-going motor vessel, built at Copenhagen, Burmeister 

 and Wain (Danish) engines. Sister vessels " Jutlandia," first British-built ocean-going 

 motor vessel, and " Fionia," purchased by Hamburg-American Co. renamed " Christian X 

 in honour of King of Denmark, and the first motor ship to arrive in New York. (4) First 

 British owned ocean-going motor vessel, built by Sir Raylton Dixon & Co. for Furness, 

 Withy & Co. Carets (Belgian) machinery, reported to be 68 tons less than if steam, and fuel 

 for 30 days 120 tons oil instead of 450] tons coal, gain of a knot speed (sec also Engineer, 

 Oct. 25, 1912). Similar engines 750 H.P. in " Fordonian." (5) Built at Hamburg, Sulzer 

 (Swiss) engines, total engine room weights 160 tons or less than half for steam engines, fuel 

 consumption about one third, engine room complement half for steam machinery (see Int.
