BISBEE. Ariz., Sept. .2s.-Vigor with which construction work and the in stallation of improved equipment toI the end of larger output and increased efficiency has been picked up with the resumption of operations in the s av- eral recent strike districts is one of the most marked features of. the pres ent period in the Arizona copper in- dustry. e. The Warren district leads in l. ais character of work at the present tir le, with Jerome second, Ray third a. 1d Globe Miami a strong fourth. At Cliff ton and Morenci plans are in abeyan ce pending the possibility of resumption of work which will add large amcmlt of activity to the construction and de- velopment division in the state, as we II as make much available in new met al resources.
 Ground was broken in the Warren district this week for the new mill to be erected by the Shattuck-ArizOna Copper company for the treatment of more than one million tons of lead. car bonates running well in silver which the company has demonstrated and which under a new process of treat ment that has been worked out will re- turn fair profit The extent of 1he lead carbonate zone in this proper ty will undoubtedly be extended as q e. velopment Is carried on and means q large gain to it's metal resources, in which copper ores predominate. The treatment process worked out by the Shattuck for its lead carbonates ap- plies with equal efficiency to a ton mage of double the extent in Copper Queen mines and for the treatment c which its new mill will be equipped. a.s well as for handling of the low grade copper ores which the steam shovels will mine from Sacramento hill Add ing of the lead carbonate work to the mill will mean ultimately a consider ably greater plant than was contem- plated in original plans.
 Breaking of ground for the Copper Queen concentrator is probably close ahead. The start has been delayed pending determination upon site for the plant, in the selection of which wa ter resources play an important part. Tests for a sufficient water supply have been underway and it is under stood that recent results have been very satisfactory and will enable early beginning of construction of plant hl association with building of the latter there will be the establishment of a townsite convenient to the mill and the carrying out of considerable house construction. The character of build- ing will be modern and desirable and afford housing facilities for all em- ployes in the concentrator division Meantime work is crowding ahead with fine results in the steam shovel divi- sion on Sacramento hill, where they are rapidly getting the ground in shape for the extraction of ore
 This work has given Bisbee an en- trely altered appearance on the sur face.
