1 MARINE REVIEW. Clamorous for an Object Lesson. Naval designers and contractors have been clamorous for years for an object lesson, wishing a practical test of the qualities of the modern war- ship in actual warfare. Naval construction has been completely revolu- tionized since the last sea fight. The battle ship of today has never been tested in actual combat. Nobody knows how it will meet the test. All judgment of the efficiency and performance of the modern naval equip- ment of defensive armor and high power guns, torpedoes, rams, magazine and rapid-fire guns, to say nothing of the new and strange devices like dynamite guns and sub-marine torpedo boats, is purely theoretical. The first actual battle may demonstrate the uselessness of means of offense and defense most relied upon, and upset theories of naval construction and warfare as completely as did the fighting of the Monitor and Merri- mac. The naval powers that have hundreds of millions of dollars in- vested in battle ships and cruisers, torpedo boats, gunboats, armor and ordnance, want to know whether they are on the right tack, and nothing but actual war will show them. The limited, but still useful, object lesson afforded in the harbor of Rio Janeiro confirmed the demonstration of the bombardment of Alexandria, that modern high power guns are no more effective against intrenchments than the old kind, and that battle ships can do little harm to moderately well built and defended forts. This was proved in the Chilian war, too, which also showed the effectiveness of tor- pedoes against ironclads.--Army and Navy Journal. Around the Lakes. Tonnage of the schooner Biwabik, new consort of the steamer Gogebic, is 1,401.78 tons gross and 1,332.25 net; official number, 3,625. Congressman W. J. White and Mr. Henry A. Hawgood, both vessel owners of Cleveland have gone to Europe. Mr. Hawgood will be away for six or eight weeks. On her summer excursion business between Chicago and Milwaukee it is intended to have the whaleback passenger steamer Christopher Columbus make two trips a week--Thursdays and Sundays. A board of officers of the corps of engineers, U.S. A., to consist of of Cols. Henry lL. Abbot, Cyrus B. Comstock, and Capt. Dan C. Kingman, has been ordered to assenible at Buffalo to consider and report upon the proposed docks at Squaw island, Niagara river. Capt. Nelson Little of Port Huron says the late Henry Howard did not have a mortgage on his farm or city property as security for an unpaid bal- ance on the wrecked schooner Shupe. The notes which Mr. Howard so kindly returned to Capt. Little after the wreck of the Shupe were secured by the vessel. Thursday night, last week, the tug Champion lost part of a raft, about 500 elm logs, stamped with the letter A, off Middle Island, Lake Erie. Anspach Bros., Oak Harbor, O., the owners, offer a reward for information: or they will pay for their delivery at Port Clinton, O. The logs were valued at $500. é Officials of the Pittsburgh, Shenango & Lake Erie Railway company and the dock company at Conneaut, O., seem to be still working on the scheme for ferrying loaded cars of coal across Lake Erie to Port Dover, Ont. They are seeking assistance from the Canadian government in pro- viding a suitable depth of water in Port Dover harbor. The new steamer, the hull of which was completed at Gibralter a few days ago, has been sold to the Shores Lumber Company of Chicago, the consideration being $68,000, The steambarge George W. Johnson is taken as part payment by the sellers. The new boat was to have been named Wolverine State; but she will now be called Adella Shores. A break in the boat's stern post was the only damage caused by the accident in launch- ing. The steamer is now in Detroit getting her machinery at the works of S. F. Hodge & Co. Here are a few sample cargoes of ore taken out of Two Harbors, last week, on the Sault canal draft of about 15 feet: Yuma, 3,024 gross tons, Maritana 2,989, Mariposa 2,949, Sagamore 2,837, Pathfinder 2,678, Pontiac 2,494, Kirby 2,383, Samuel Mitchell 2,327. The steamer Alva of the Brad- ley line, Capt. Holmes delivered 3,511 gross tons of ore at Ashtabula, Monday, from Escanaba. She was drawing 16 feet 3 inches. The steamer Merida of the Whitney fleet, Detroit, loaded at Ashland, Tuesday, a cargo of ore that would weigh 3,620 net tons. July 4 is the day set for the launch at Philadelphia of the American Line steamer St. Louis, while the St. Paul will be daunched two months later. The proportion of length to beam in these steamers is 8.5 to Lean the Paris it is 8.36, in the Campania 9.23, and in the Teutonic 9.82, the lat- ter being the long narrow model characteristic of the Harland design. In internal arrangements characteristic features of the New York are to be maintained, although the details differ. When the four vessels are on the service--the Paris, New York, St. Louis and St. Paul--then the contest between Southampton and Queenstown will be entered upon in earnest Hitherto it has been a one-sided contest.

The Gas Engine and Power Company of Morris Heights on the Har- -foot twin-screw naphtha launch for Charles Fleisch- man. Crawford & Fehrenbatch is the name of a new firm, of which John Fehrenbatch, late supervising inspector of steam vessels at-Cincinnati, is a member. J. S. Winslow & Co. of Portland, Me., have just closed a contract with the Hon. William Rogers of Bath, Me., for a four-masted wooden schooner of about 1,000 tons register. é Part of the foundry plant of the Worthington pump works at Eliza- bethport, N. J., was burned recently, with au estimated loss of $100,000, but repairs will be made hurriedly, so as to cause little delay in work which the company has under way. '--. M, Brown, representing the Scott Electrical Manufacturing Com- pany of No. 26 Liberty street, New York, is visiting lake cities with a view to introducing an oil search light, which is an adaptation of the Scott com- pany's well known Huntington electric search light, substituting oil for electricity. This oil light is especially suited to yachts and pleasure boats having many landings to make in rivers, as it can be sold for about $100, and the cost of maintenance is nominal. See & Jaques, engineers and. naval architects, No, 1 Broadway, New York, is the heading to a circular letter received a few days ago, in which Capt. W. H. Jaques, formerly with the Bethlehem Iron Company, announces that he is now associated with Mr. Horace See and others and will engage in general engineering work and consultation in connection with the manufacture and treatment of guns, armor, shafting and other war material, the machinery required for their production, and especially with the fluid compression and hydraulic forging of steel and the best types of armor. Horace See of No. 1 Broadway, New York, sends out a list of sixty-five sea-going steamships, vessels of war and steam yachts, to which his hydro-pneumatic ash ejector was fitted up to May 1, 1894. Mr. See has also issued some interesting circulars' regarding the Yarrow water tube boiler, for which he is agent in this country. The circulars include ex- tracts from papers regarding the boiler, which were read at the last annual meeting meeting of the British Institute of Naval Architects, and also re- ports of the trials of the torpedo boat chaser Hornet, which was fitted with the Yarrow boiler and which attained a speed of 28 knots. The Yarrow Boiler. At the last annual meeting of the British Institute of Naval Architects, Mr. Yarrow, whose tubulous boiler has attracted so much attention in Great Britain, spoke of the results obtained with one of the boilers of the torpedo boat chaser Hornet. It weighed complete, with fittings smoke- box, fire-doors, firebricks, funnel, casings, and all boiler mountings, also including water up to working level, 5 tons, 7 cwt. On carefully conducted experiments in the yard it was found that 12,500 pounds of water were evaporated per hour from 60 degre*s Fahrenheit to 180 pounds pressure. In order to compare the relative efficiency of water tube boilers. with loco- motive boilers, there were the following facts: In the Havock his firm had placed two locomotive boilers, and the machinery indicated on trial about 3,500 horse power, with an air pressure of 3 inches. In the Hornet, a sister ship, provided with similar engines and fitted with eight water tube boilers, they obtained, with a very low air pressure, averaging 1¥ inch, 4,300 horse power. The eight boilers in the Hornet weighed "11 tons less than the locomotive boilers in the Havock. . Grain receipts at Buffalo during May were nearly 7,000,000 bushels less than a year ago, but the receipts of flour were over 600,000 barrels in excess of those of May, 1893. Shipments of anthracite coal from the same port for the month of May, 1893, were 363,435 tons; during the month just | ended the amount shipped was only 230,747 tons--a falling off of 132,688 tons. The Erie canal, however, is credited with a remarkable business in spite of low rates. During May 6,808,746 bushels of grain were taken to tide water and intermediate points, against 5,505,041 bushels in the same month a year ago. REASURY DEPARTMENT, U. S.
