MATERIAL IS ARRIVING FOR 4 STEEL APPROACH TO ORE
 BINS.
IGlnha RelLl

Notwithstanding the stormy weather of the past two weeks and the recent interruption of traffic on the Gila Valley, Globe and Northern railroad resulting therefrom, the Old Domin- ion Copper Mining and Smelling Com rany's operations have been in no wise restricted. The smelter has con tinued to run at the full capacity of the plant. making the normal output of copper The supplies Of coke and sulphides ran very low, which caused some apprehension of shut down, but such a contingency is now improb- able. as sulphide ore is again arriving from Bisbee. and advices have been received of sixty-six cars of coke in transit and more to follow.
 Underground work has progressed very fayorably. and while the report in circulation here of an important strike of sulphide ore in the crosscut
 n the fourteenth level is not true, the opening not having reached the ore zone yet, it can be truthfully said that the lower levels never before showed so much sulphide of ore of good quality as they do at the pres ant, and the stopes on all the levels show improvement.
 The new shaft is going down as rapidly as three shifts can sink, and work will continue until a depth Of 1OO0 feet has been reached. A sec ond shaft IS badly needed, as the capacity of the big shaft is taxed to the limit. IL is the intention of the management to sink two additional shafts next year, work on which will not likely begin until late in the spring. The extensive plans for new shaft openings indicate very plainly the excellent conditions underground. Additions to the smelting plant are being made to meet the improvement in the mine and to handle the larger output of ore expected within a few months. A new rectangular furnace. similar 10 the three now in commis- sion. will be shipped from the east the beginning of January. To accommo- date this furnace an extension to the Smelter building on the north was erected, which is thirty feet and five inches in length, and in addition to |, this steel approach to the ore bins will replace the wooden structure. The. structural steel for this improve ment is being unloaded at the smel- Ger A temporary bridge is now being built to connect the ore bins with the feed floor of the shelter, while the steel construction is in progress. It Is also planned to extend the flue dust chamber to meet the requirements of an additional furnace. A new blower of 10000 cubic feet per minute capac- ity was recently installed in the smell | ter power hous@
 An improvement to the bridIetting machine, devised by Shelter Superin' ] tendent c. F. Shelby. has increased ! its capacity from 100 tons Fer day to f 150 tons. Formerly the machine made small circular bricks. The molds were arranged in groups of | three around the disc By cutting out | the divisions between these molds an brick about four times the size of the original product is molded, and | which possesses the additional advan- tage of being harder and much better , for smelling. Another briquetting
 machine of the same type will be
 shipped to the old Dominion from
 Bisbee, which wiii give a daily ca pacity of 300 tons.
 The enlargement of the concentra-
 tor to make is cap2city 450 tons Is an
 other improvement under way.
