WARREN, JEROME AND RAY DISTRICTS SHAPING UP FOR OPERATIONS; COPPER OUTPUT TO BE GREATLY INCREASED.

10 the end or larger output ana m
 creased efficiency has been picked up
 with the resumption of operations in
 the several recent strike districts is
 one of the most marked features of
 the present period in the Arizona cop
 per industry.
 The Warren district leads in this
 character of work at the present
 time, with Jerome second, Ray third and Globe-Miami strong fourth. At
 Clifton and Morenci plans are in abey- ance pending the possibility of re-
 sumption of work which will add a
 large amount of activity to the con struction and development division In the State, as we'll as make much avail able in new metal resources.
 Ground was broken in the Warren district this week for the new mill to be erected by the Shattuck-Arizona Copper Co. for the treatment of more than 100000 tons of lead carbonates running we'll in silver which the com
 pany has demonstrated and which under a new process of treatment that has been worked out will return fair profit. The extent of the lead carbonate zone in this property will undoubtedly be extended as develop ment is carried on and means large gain to its metal resources, in which copper ores predominate. The treat ment process worked out by the Shattuck for its lead carbonates ap- plies with equal efficiency to ton mage of double the extent in Copper Queen mines and for the treatment of which its new mill will be equipped, as we'll as for handling of the low grade copper ores which the steam shovels will mine from Sacramento hill. Adding of the lead carbonate work to the mill will mean ultimately d considerably greater plant than was contemplated in original plans.
 Breaking of ground for the Copper Queen concentrator is probably close ahead. The start has been delayed pending determination upon the site for the plant, in the selection of which water resources play an important part. Tests for a sufficient water sup ply have been underway and 1t is un- derstood that recent results have been very satisfactory and will enable early beginning of construction of plant. In association with building of the latter there will be the establish ment of a townsite convenient to the mill and the carrying out of consider able house construction. The char acter of building will be modern and desirable and afford housing facilities for all employees in the concentrator division Meantime work is crowd ing ahead with fine results in the steam shovel division on Sacramento hill, where they are rapidly getting the ground in shape for the extrac- ton of ore.
 This work has given Bisbee an en- tircly altered appearance on the sur face. From the street the pedestrian looks up to the top of the once point ed and crag bcdcckcd mountain to see railroad trains, pulled by standard gauge engines, running around the rim more than 500 feet above the bottom of the gulch. The peaks of the mountain, landmarks of the old days, have about disappeared. In an- other year they will all be gone, the bulk of the hill coming down with them day by day until it has disap- pearcd. The gigantic work on the surface that this job represents, how ever, is small in comparison with the total of operations beneath the sur face in the district, where there are hundreds of miles of drifts, raises and other openings in the solid rock, and where the transportation service represents niore steel track over which cars operate than there IS rail road and street railway mileage com bincd in all of Arizona. Hundreds of miles of copper wire arc there to carry the current which pulls the cars laden with orc going to the outside to be turned into more copper wire. Steel, cars and copper employed in this comparatively small side-division of mine operation may give some idea of the enormously, increased expense to which higher cost of these supplies during the last several years has meant to the mine operators.
 In the development division in the Warren district there is largest inter est centered at the immediate time in thc Dcnn Arizona \ million dollars
