year This addition will consist of ! two reverbatory furnaces and five McDougal roasters, such as have re-
 gently been installed at Cananea by
 Dr. Ricketts. These furnaces will be ! 100 feet in length and will be con

 commodate three McDougal roasters and that many roasters have been on the ground at the Queen smelter
 for nearly year. but it has now
 been decided to install five roasters
 and they have been ordered and the
 additional building material.
 The additional bu lding will extend

 naces and roasters. This new feature
 IS for the reduction of fiue dust, con centrates and dust ores which come out of the c. Q. mines at Bisbee. It is expected to materially lower the cost of production from this class of charge which now goes into the blast furnaces.
 The October output at the Copper Queen smelter amounted to only S. s00,0o0 pounds of copper, which is nearly 2,0o0, 900 less than the output for the minths of March and August when about 10. 0.7O0.0 900 pounds was pro duced for each. There are nine fur naces now in operation at the Queen. The number of furnaces in blast dur ing the past three months has been regulated by the quality of ore used for the charge, as the policy has
 been to hold the Queen product at about the same monthly figure. More or less depends upon custom ore re- ceipts, which are not large now. the principal customer in the custom de- ratment be ng the Shattuck, which is sending about 100 tons daily. The Queen output also includes the out put from the concentrates sent up daily from Nacozari by the Moctezu- ma Copper company.

 While nothing was given out af- er the visit of the controlling di- ectors and officers of the Calumet Arizona company at the shelter 1 ast week, it is believed that they are flaming extensive work at their liant during the coming year. 1n- aediately after the directors returned lome General Manager Greenway of he C. & A., James Wood, smelter | of the same company | md Dr. l.. D. R-cketts of the Greene ,anauea, left for an extended trip i, which will take them to the copper amps of Montana, Utah and Nevada. The c. & A. have been gradually en- arsing their original furnaces from | goo ton to 500 ton capacity, until now | .hey have five of the larger capacity 1 and one of the smaller capacity | Just what enlargements are in con | by the C. & A. of their | shelter can only be surmised, but l something in that line is confidently l expected. It is known that the mines of the c. & A. and the s. & r. at Bisbee could double the ore output at any time it is desirable to make such an increase in the output. The out put of the c. & A, smelter last month to something over 400, 900. or about 100000 less than the output for the record month of the year. The precent C. & A. smelter plant could easinly produce two or threee millions more if such an increase in output was desired.
