An ex- perienced and careful mining expert who is himself largely in- terested on the range, gives us the following estimates of the ore: Hale mine, about 58 per cent. Fe, .o80 P; Kanawha, Cin- cinnati & Canton, 60 Fe, .o40 P; Biwabic, 58 to 59 Fe, and .o80 to .ogo P; McKinley, 58 to 59 Fe, .045 P; Mesaba Mountain, _ one shaft in ore 61 Fe, .030 P: Mountain Iron Company, 58 Fe. and .ogoP. All other mines are mere 'prospects.' The Biwabic Canton and Cincinnati are large mines that could probably pro- duce after the first year 250,000 to 500,000 tons a year. 'he Hale, Kanawha, McKinley and Mountain are smaller, with a prospective capacity of 75,000 to 100,000 tons a year. T'he others are very small." An interesting paper on American iron ore deposits has been prepared by John Birkinbine, president of the American Insti- tute of Mining Engineers, for the journal of the British Iron and _ Steel Institute. This paper was prepared with special reference to the localities visited by the members of the institute when in this country in the fall of 1890, and much interesting informa- tion has been embodied in it. Mr. Birkinbine describes in a general way in his paper the different ranges in the Lake Super- ior district and presents also some detail regarding development and shipments from the Chapin, Colby, Ashland, Aurora, Michi- gamme, Champion, Republic, Cleveland, Lake Superior, Jack- son, Queen and Prince of Wales mines. Mr. Charles L. Lawton, superintendent of the Platt Mining Company's mine on the Cascade, Marquette range, has recently sent to Crystal Falls specimens of the purest hematite ore ever unearthed in the Lake Superior basin. An analysis of the ore shows it to run 69.72 in metallic iron, .o42 in phosphorous and 51 silicia. A specimen of this ore will accompany the Lake Superior mineral exhibit to the World's Columbian Exposition. Mr. Lawton was formerly a resident of the Crystal Falls district. --Diamond Drill, Crystal Falls. Ohio democratic politicians who are interested in the Ohio . Mining Company seem to be spending most of their time on the Mesaba range of late. A party on the range last week consisted of ex- Governor James E. Campbell, ex-Lieut. Governor Sea Marquis, Dr. J. A. Norton, railway commissioner, ie WW geet Aw, L. Thurman, E. D. Sawyer, C. Nester, P. Bartlett, H. H. Recker, McK. Dunn, Price McKinney and Benjamin Wanner. The management of the Volunteer company, Marquette range, has discharged 250 employees. The men laid off were miners and surface men, and only 100 men are retained. This step was taken by the owners of the mine because of the large amount of ore now in stock unsold. The stock piles are estimated to contain 115,000 tons. Proposed New Fog Signals. While the bill now before Congress for light-house measures on the lakes was being prepared, experiments were being con- ducted at the light-house depot, Staten island, New York, with an instrument for producing sound-fog signals, and it was, and is yet, thought it is possible that this instrument may be intro- duced in place of steam fog-signals. The bill called for steam fog-whistles, thus limiting the light-house board to a particular kind of fog signal. These are costly to install and expensive in operation, whereas, if the instrument spoken of as now being ex- perimented upon proves successful, fog-signais can be introduced and operated quite as effectively and at much less cost of installa- tion and operation. It was on this account that the bill was changed so as to provide simply for fog-signals instead of steam sirens. A letter from the board on the subject says: " Major Heap, the engineer of the third light-house district, conceived the idea of coupling together three entirely different machines, namely, a hot air engine, a siren and a blower, to see what the result would be, and what changes in any or all of the machines might be necessary to obtain a thoroughly satisfactory fog-signal. Major Heap is still experimenting, and has not yet gone beyond: a point where the experiments promise very well for the future, but the actual use of the signal at a light-station and in foggy weather is the only practical test on which the board would feel authorized to work. But as the experiments so far are promising very well, and as the cost of putting the machines up in the first place would be greatly diminished and . the expenses of running them would be very much less than the ordinary steam whistle, and the result obtained probably quite as good, the light-house board naturally desires to reserve to itself the opportunity of using the better signal, in case actual use demonstrates its superiority. Had the bill passed with the words 'a steam fog-whistle,' the board would have been debarred from putting in any improved form of apparatus, as the effect of limitations of that nature is always held by the accounting officers of the treasury as being binding, and as admitting no improvement or change, no matter how much better apparatus may be found after the passage of the bill." To Suggest Changes in Steamboat Laws. When Senate bill No. 1,755, the obnoxious Frye measure .proprosing regulations for steam vessels, was before the com- merce committee of the Senate some time ago, several meetings of marine organizations were held at No. 50 Wall street, New York, to protest against the bill and to provide for opposition to legislation of this kind in the future. The organizations repre- sented at these meeting were the National Board of Steam Navi- gation, Board of Trade and Transportation of New York, New England Association of Boiler Manufacturers and Iron Ship Builders, Marine Boiler Builders of New York and vicinity, United States Standard Steamship Owners', Builders' and Un- derwriters' Association of New York and branches No. 50, 56 and 69 of the Marine Engineers' Beneficial Association. Rep- resentatives of these organizations met again in New York last week and adopted the following resolution: Resolved: 'That it is the sense of this meeting that the in- terests of the merchant marine can be best served by the consid- eration, by the various associations here represented, of such portions of the business in which they are interested, and the preparation by such association of such changes therein as they may consider of advantage; and further, that it is the sense of this meeting, that such changes should be put into final shape before December 1, 1892, that they may be properly presented to the board of supervising inspectors at their next annual meet- ing in January, 1893. St. Mary's Falls Canal Traffic. The St. Mary's Falls canal was open ten days in April and the freight movement in that time amounted to 256,977 net tons, of which 162,504 tons was westbound and 94,473 tons east- bound. 'The westbound traffic exceeded the eastbound for the reason that ports at the head of Lake Superior were closed by ice for some time after the opening of the canal. Shipments through the canal for the period named were divided as follows: Westbound--Coal 151,495 tons, manufactured iron 119 tons, salt 17,842 barrels, unclassified freight 8,214 tons. EKastbound-- Flour 67,250 barrels, corn 31,000 bushels, wheat 2,042,114 bu- shels, iron ore 19,485 tons, lumber 1,563,000 feet, unclassified freight 3,778 tons. Two of the light-ships, Nos. 52 and 54, building at the yard of Wheeler & Co. West Bay City, for service on the Atlantic coast, were launched at the same time on Saturday.
