THREATENED STRIKE OF MA- RINE ENGINEERS. The Marine Engineers' Beneficial Association has presented to the steamship and tug boat companies at the port of New York a demand fer a new wage scale, to go into effect Oct. J, the failure of the employers to. sign is threatened to cipitate- a strike, affecting every vessel on the Atlantic flying the flag, including the coastwise lines 1o the Gulf of Mexico and the various interests operating ocean going tugs. The engineers demand increases va- rying from 5 to 10 per cent, the wage to be paid being governed. by the class of vessel on which the engineer is at work. A working day of eight hours is also demanded, together with regulations regarding overtime, holi- days, Sundays, etc.' In addition pro-. vision is made for boycotting any company which may discharge an en- gineer belonging to the association, providing that it can be shown that his membership in the association is the reason for his dismissal. It is. anticipated that the steamship compa-. nies will present a solid front against granting the demands, but the engi- , neers are optimistic of sttccess, as they believe that their, wishes will be acceded' to, rather than that shipping should be so thoroughly tied up. Among the lines which would be af- fected would be the Clyde, Morgan, Mallory, Metropolitan, Old Dominion, Sayannah, Fall River, United Fruit, American, Red Star, Ward, Panama and Red D. The fleets of ocean-going tugs which would be affected include Merrit & Chapman, Luckenbach, Mo- ran Towing Co. and the Standard Off Go; which pre- Arrerican THIRTY KNOTS FOR NEW LIN- ER. That- the Harland & Wolff Ship- building Co., Belfast, are to con- struct a steamship designed for trans- Atlantic trade which is to attain the speed of 30 knots an hour, has been definitely decided upon and the an-. nouncement has been made by the, Right. Hon. A. M. Carlisle, managing © director of that company, in an au- thorized statement. "This vessel," said Mr. Carlisle, "is to be a steamship of about 14,000 tons register and about 580 ft. in length. She is to. have triple screws, two fixed as they are at present on twin-screw vessels; the third in the rudder cavity as in the ordinary single-screw vessel. The two outside screws are to be driv- en with quadruple-expansion engines of the Harland & Wolff balanced type, ; x .220 pounds to the square inch. WTAE Marine. REVIEW and working up to a pressure of about The central screw will be operated by a turbine engine. "In a few years' time steam propul- sion may be a-thing of the past. But as matters rest today there is much scope for further development. With a judicious combination of turbine and compensating engines, the construc- tion of a vessel. that can cross the Atlantic at 30 knots an hour is easily practicable. ' "At any rate, we mean to demon- strate it with one of the nine new liners which we are to build for the trans-Atlantic service." These nine ships are to be built for the International Mercantile Ma- rine Co. the Belfast yards, and the first of these for the Canadian trade, will be launch- ed next spring. It is on this ship that the new method of propulsion will be tested. ' The idea, Mr. Carlisle added, was not: exactly new. Lord Pirrte, head of 'the Harland & Wolff Co., had en- tertained it for some time. Asked how it developed, Mr. Carlisle said: "It took shape while Lord Pirrie was on board the Lusitania in the new leviathan Cunarder's trip around Ireland. We were invited, Lord Pir- rie. and JI, >to join 'the party. - The whole matter was discussed with Messrs. John Brown & Co.'s repre- sentatives, who are now our working partners, so to speak. After all, there is really nothing very extraordinary in the suggestion. of a 30-knot turbine liner. Such a boat can be built just as easily.as a destroyer of equal speed, but I am inclined to think the latest type of oscillating engine, working in - conjunction with the turbine, is a dis- tinct advance on either system worked separately, because more can be taken out of the material at hand." STELLAR AZIMUTH MACHINE, Capt. Robert T. Lawless, who, for many years, has been in the employ of the Oceanic Steamship Co., in command of the steamship Mariposa, that plies between San Francisco and Tahiti, will leave the former place very soon for a trip to London. Capt. Lawless has been for years a tireless student of the problems of navigation, and, in recognition of his services to the sci- ence, his name has been proposed for membership in the Royal Geo-. graphical Society, of England. The particular service that has brought him this recognition, from abroad, is the stellar azimuth machine that Capt. Lawless has lately invented. Two are already latd down in. 19 This instrument solves spherical tri- angles mechanically, and with abso- lute correctness, and makes unneces- sary the use in navigation of an azi- muth table. By means of this machine, a course 'may be set on a pitch dark night, and to navigators particularly, and partic- ularly navigators of war vessels, this is invaluable. The United States is now making extended tests with Capt. Lawless' machine. While in Europe, he expects to interest the British ad- mirality and the French. government in the new instrument. Capt. Lawless believes that every officer of every passenger liner should understand stellar navigation. The compass, he says, is the most useful of instruments, but the most frivolous and vacillating, and requires constant -- watching and testing. The! compass should be checked up every four hours, and even then it may play tricks on the most experienced naviga- tor, he declares. However, the stars are always true beacons, and the nav- - igator who can steer by star sight, says Capt. Lawless, can be as sure of his course as if he had cross-bearings between two lights. Capt. Lawless designed the instrument for his own use, and says that he would not go to sea without it, as it makes him independent of the use of the compass. NEW SALVAGE COMPANY. The Duluth Marine Salvage Co., Duluth, Minn., is a recent incorpora- tion under the laws of the state of Minnesota, the incorporators being Leo A. Ball, Florence McKay. and Thomas A. Gall, all of Duluth. The company purposes to carry on a gen- eral wrecking, towing, lightering and salvage business and to do all kinds of contracting and construction work. The capital stock is $100,000. The O'Donnel & Sandstrom Ship Building Co., Hoquiam, Wash., has re- cently been awarded a contract by E. S. Estabrook, 'of San Francisco, Cal, for the construction of a steam schooner for use between San Francisco and the Co- quille river, replacing the Fifield which was recently destroyed by the fire in the Price ship yards at Bandon, Ore. The new vessel will be known by the same name and is to be \186 ft. long, 40 ft. beam and 11 ft. depth of hold. The machinery has already been built at San Francisco and will be installed at the yard, making her the first steam schooner to be completely built and equipped on Gray's Harbor.
