The Minnesota com- pany's regular quarterly dividend of 1% per cent. and $1 a share from the Chandler company arrived with the first days of the new year, but there is no talk of any additional sharing of profits by other companies. It is of course expected that the Pittsburgh and Lake Angeline company will continue dividends of $2 a share each month, and it is thought that the payment off1a share by the Chandler company with the opening of the year will be followed by a similar dividend every two months, but there is nothing definite as to this latter expectation. Furnace men are unwilling to pay advanced prices for ore for next season's delivery and the producers can not afford to sell at less than about 50 cents a ton advance, on account of the certainty of in- creased lake freight. 'Thus there is again a waiting disposition in the market, but the conditions favor the producers of ore, who are making preparations for a big output, and any advance in the price for next season will help the market for iron mining stocks. . In 1890 shipments of iron ore from Escanaba were greater in the aggregate than the shipments of any other port in the world, not excepting Bilbao, Spain. Escanaba shipments for 1891 have, however, fallen short of the aggregate for 1890, be- ing but 3,052,813 tons, against 3,054,910 tons shipped from Bil- bao during the eleven months between Jan. 1 and Nov. 30, 1891. Stock in the Chandler mine has sold during the past week at $48, ex-dividend. At this price per share the Chandler pro- perty, although only a lease, represents an aggregate value of about $2,000,000. A surplus of more than $750,000 held by the company is the cause of the present value of stock. _- Mr. T. F. Cole assumed the management of the Chapin mine at Iron Mountain on Jan. 1, and Capt. Tresona was made superintendent of the Buffalo at Negaunee. Report of Experimental Trip, MADE UPON SCREW STEAMER E. P. WILBUR TO THE BUILDERS THE GLOBE IRON WORKS COMPANY, CLEVELAND, O., [BY GEO. C. SHEPARD.| The engines ran smoothly and without a hitch except for the pound of pumps attached, and the maximum power obtained in this case, that of 1600 I. H. P. is not the highest that might be obtained by carrying the steam higher in and cutting off longer. Even with this indicated horse power we get the good result in I. H. P. per square foot of grate surface of 9.8 I. H. P., and the I. H. P. per ton of machinery is 6.25. : The "Wilbur" burned on this trip 239 tons of coal and this seems excessive until the quality of coal is understood. The 29% refuse in most of the coal would not only fail to produce heat itself but would prevent the combustion of the carbon and other heat producing elements. Another reason for excessive consumption of fuel may be found in the practice of running when light with the throttle two-thirds open, preventing the use ofthe whole expansive quality of the steam. Again the steam steerer was very wasteful as shown by a strong exhaust. This may explain why the indicated water consumption is so 'much lower than the actual water feed to boilers. A careful in- vestigation might develop the fact that the pitch of the screw was excessive for the diameter and for the power of the engine and thus again account for large fuel bills. This report and the trip before it was made more especially for the satisfaction of a commercial rather than a purely techni- cal interest; to determine the efficiency of this combination of hull, boiler, machinery and screw, but many points of technical interest have necessarily been brought out and were it so desired the data are sufficient for many more. Considering that the vessel was to proceed with all despatch, that the weather was not always propitious and that assistance was often wanting, the data are all that could be expected, and to Mr. Whitney, chief engineer of the line, and to Mr. LC. Crouch is due much of the success of the trip. * TABLE 6. DATA FROM GENERAL TESTS.
