one barrel of oil costing $1.00 does the work of 0.4 tons of coal costing $1.80. Aside from' this) the deliveriés of coal aré very irregular and the oil is much cleaner, easier and"more economical to handle." These are'the reasons that the -Kitsap and' 75 per cent of the oth- er steamers'on Puget Sound burn oil. 'One hundred electric lights, the cur- rent for which is furnished by a 7- kilowatt DeLaval turbo-generator, are used: to illuminate the cabins: The turbine runs at 30,000 r: p. m. driving the generator, through reducing gears, at 3,000 ft. p.. m. = This..set. has. the special advantage of exceptional com- pactness and has proven itself to be economical and reliable in operation. The entire mechanical equipment is decidedly superior to the average small passenger steamer and compares fa- vorably with that found in the finest private yachts. The wisdom of incur- ring the extra expense which this equipment involved has been _ thor- oughly demonstrated by the 'speed, minimum repair bills, economy and re- liability of service that has been ob- tained from the Kitsap. As was stated in the beginning ee Kitsap is capable of a sustained speed of 18% miles per hour; the speed on the every day run is 17 miles per hour. The boat is licensed to carry 300 passengers.

Contract was awarded by Secvzetary of the Navy Metcalf. on Sept. 29 to the Electric Boat Co. of New York, for the construction of seven subma- rine torpedo boats out of the appro- priation of $3,000,000 made for this purpose by congress at its last ses- sion... Four of the boats will be-of the same size as the: Octopus, the successful competitor conducted by the naval board appoint- ed for that. purpose. "Three others will be of the same type but of greater displacement and higher speed both as regards surface and merged conditions. The barge Santiago of the Gilchrist fleet, which sank at the dock at Es- canaba while loading on August 20, and which has just completed repairs at Milwaukee, will be towed to Toledo to unload. The vessel is in charge of the underwriters, having been aban- doned to them after sinking at the dock at Escanaba.

The loading and dis- in excess of has 12 derricks Howden-on-Tyne, what is usual. She 45, and ten: powerful steam winches. The machinery has been: specially: designed and constructed from' entirely: new patterns by Messrs. Richardson, 'West- garth & Co. Ltd' The 'cylinders°are 28 in. 46 in..and 77 in' diameter by 54 stroke. The go-ahead and go-astern guides are carried on independent front and back columns. The crank shaft is in three interchangeable parts, and is made of ingot steel throughout, whilst the bed plate is sufficiently deep to bolt direct on to the top of the tank without intermediate seating. Every bearing throughout the engine is adjustable and easily manipulated while the engine is working." Steam from the low-pressure cylinder is con- veyed to the condenser by a separate exhaust pipe, and space is allowed on top of the tubes for steam to spread the full length of the condenser, the condenser tubes being packed with close-ended screwed brass _ ferrules and cotton cord packing. Steam is supplied by three boilers which work at 180 lbs. pressure. During the trial runs of the steamer, the machinery worked with smoothness and_ effi- ciency, over 3,000 I. H. P, being: .ob- tained with 69 revolutions, with less than two in. of draught at the fan, while a mean speed of 1234 knots was obtained. TORPEDO BOAT GOYAZ. The first-class torpedo boat Goyaz, just completed by Messrs. Yarrow & Co., of Poplar and Glasgow, for the Brazilian government, left Gravesend on Wednesday, Sept. 4, for Brazil. The vessel is 152 ft. 6 in. long, by 15 ft. 3 in. beam, and has a speed of 26% knots. . Instead of the usual reciprocat- ing machinery, it is propelled by tur- bines combined with a small. triple-ex- - pansion reciprocating engine, the latter being used for cruising on account. of its superior economy at slow speeds. The Goyaz is designed to carry two 47 mm. quick firing guns, and two 18-in. torpedo tubes. The hull is of the Yar- row standard type for first-class tor- pedo boats, being in all respects simi- lar to 26 others that have been built for the Chilian, Austro-Hungarian, Japanese and Dutch governments. Those built for the Japanese govern- ment did excellent service in the Rus- so-Japanese war, and: the Austro-Hun- garian government are themselves building twenty vessels exactly to this design. Capt. Wm. 'S. Carloss has been ap- pointed master of the steamer Cale- donia to succeed Capt. J. W. Nich- olson, deceased.
