TAE MarRINE REVIEW. LAUNCHING OF THE HENRY B. SMITH. The freighter Henry B. Smith, building for W. A. and A. H. Hawgood, was launched from the Lorain yard of the American Ship Building Co. on Wednesday of this week, . and was christened by Mrs, H. B. Smith, of Bay City, Mich., wife of the man in whose honor the boat was named. The Smith is in the 10,000-ton class and is 545 ft. over all, 525 ft. keel, 55 ft. beam and 31 ft. deep. She has thirty-two hatches, spaced 12 ft. centers. Her engines are triple expansion with cylinders 23%, 38 and 63-in. diameters by 42-in. stroke, sup- plied with steam from two Scotch boilers, 14 ft. 6 in. by 11 ft. 6 in., fitted with Ellis & Eaves draft and allowed a pres- sure of 180 pounds. Among those present at the launching were Mr, and Mrs. Henry B. Smith, of Bay City, Mrs. Guy H. Moulthrop, of Bay City; Mr. T. J. Lovett, Michael Connelly, J. A. Weis- beck, Miss Wood and Miss Williams of Buffalo; Mr. George Donnenwirth, of Bucyrus, Mr. and Mrs. W. A. Hawgood, Arthur C. Hawgood, Miss Arla Hawgood, Capt, and Mrs. A. H. Hawgood, Miss Aldyth O. Hawgood, Harry B. Haw- good, Mr. Joseph Avery, of Coraopolis, Pa.; Miss Overy, Mrs. Capt. A. B. Keller, Miss Elizabeth Keller, Miss Minnie Jones, Miss Clara Frederick, R. G. Miller, L. J, Cameron, W. E. Ward, Mr. Walters, H. R. Herriman, Robert Logan, R. C. Wetmore, Robert Wallace, Mrs. W. C. Monroe, Miss Dorris Bond, Capt. and Mrs. C. C. Balfour, Thomas Braund, Burton Dake, Harland Newell, Harvey R. Hawgood and Frederick Leckie. LUNKENHEIMER BRANCH STORE IN NEW YORK. The Lunkenheimer Co., of Cincinnati, Ohio, who are the. largest manufacturers of high grade engineering specialties in the world, have on May 1, 1906, opened a well equipped branch store, at 66-68 Fulton street, New York city. Previous to the above date, the company maintained a suite of offices in the Havemeyer building, 26 Cortlandt street, through which offices the export trade of the concern was transacted. While the trade in New York city and eastern states were able to a great extent to procure Lunkenheimer engineering appliances from the various supply houses, nevertheless the increased demand for these well known specialties necessi- tated the opening of a branch from which the supply houses and trade in the New York territory could be instantly ac- commodated. It is not necessary that the high standing of the Lunken- heimer company as manufacturers of engineering appliances be called to the attention of users of this class of goods, as their superior products are well known among the trade. The same courteous attention characteristic with the com- pany, will be found to prevail in their new establishment. Being grateful for the patronage of the eastern trade, it is their endeavor to further accommodate the trade by prompt attention to all orders, to do which they have gone to quite an: expense by opening their branch store and supplying same with a large and complete line of their many specialties. FORCED DRAFT. "Forced draft," said Admiral Melville in a recent paper, "dates back to Stevens' Rocket, and its first use for marine purposes was by Mr. Robert L. Stevens on the Hudson river steamers in our own country prior to the civil war. During that war Mr. Isherwood built a number of gunboats which used forced draft, but it had fallen into disuse until about 1882 for naval vessels, when it was introduced into the Eng- lish navy and still later was applied in the merchant service. In nayal machinery forced draft has been of the greatest possible importance, because it has reduced boiler weights . probably almost one-half. In the navy the natural limita- tions as to space and weight prevent the use of forced draft 35 with very much economy of fuel. It is obvious that if the rate of combustion is increased from 15 pounds of coal per square foot of grate to 40 pounds, there ought to be an at- tendant increase of heating surface. In the merchant service, or at least in certain classes of vessels in that service, it is possible to do this, and in one of my annual reports I made a comparison between the boilers of a merchant vessel called the Iona and those of the Baltimore. In the Iona there were 75 feet of heating surface for 1 grate, while in the Balti- more the ratio was about 30 to 1; but had the Baltimore's boilers been designed with any such ratio, their weight would have been almost double the weight of all the machinery of that vessel as actually built." . GAS ENGINE FOR MARINE PROPULSION. _ At the ship building yard of Messrs. Beardmore, the de- velopment of the gas engine for marine propulsion is being actively pursued, and one of the problems it is sought to solve is that of stage compression, so that the sudden stress of explosion, which may be 600 pounds, might be reduced, as it naturally causes injury to the parts affected. In the reciprocating engine the pressures in the cylinder are, of course, considerably lower than this, and the wear and tear is therefore less, and the risk of fracture correspondingly so. Submarines are being fitted with gas engines, and though no large vessels have so far been fitted, the prospect of the near future is bright, as many experts are working hard to remove objectionable features. APPOINTMENTS OF MASTERS AND ENGINEERS. L. P, & J. A. SMITH CO., CLEVELAND, 0. Vessel. Captain. Ingineer. Str. Rhoda Stewart G. H. Ferguson Schr. Mikado Schr. Potter Schr. Wm. Grandy Schr. Racine H. BP. Baldwin Schr. Constitution Frank Jennings David J Gleason Alex. Blakelee PERSONAL. Mr. T. R. McCarthy, steamship and freight broker, 404 Board of Trade building, Montreal, has just been ap- pointed agent at Montreal to the Nordisk Skibsrederforfning (Northern Ship Owners' Association) of Christiania, Nor- way. This association was established in 1889 by the owners of steam and sailing vessels in Norway, Sweden and Denmark for the protection of their interests, both at home and abroad. M. C. Furstenau, consulting marine engineer and naval architect, announces that he has severed his connection with the firm of Melville & Macalpine, and has opened an office on his own account at No. 308 Walnut street, Phila- delphia, Pa. : Wm. H. Taft, secretary of war, has accepted the position of associate justice of the United States supreme court, suc- ceeding Justice Brown, resigned. This appointment removes a very interesting figure from politics. The steamer Wm. G. Mather, of the Cleveland Cliffs Iron Co.'s fleet, was damaged in collision with the steamer Mid- land Queen at Ambherstburg this week. Two holes were stove in the port side at the water line, and the steamer was taken to the Ecorse yard of the Great Lakes Engineering Works for repairs. Thomas R. Harvey, the proprietor of Harvey's Marine Bureau at Sault Ste. Marie, accidentally fell overboard the steamer Goodyear near Thunder Bay lighthouse and was drowned. Mr. Harvey was the local manager of the Postal Telegraph Co. and city agent for the Canadian Pa- cific Railway Co.
