GREAT ECONOMY AT GREENE
 SHELTER
Seven Boilers Now Do More Work Than Was Formerly Done by Ten, and Force De- creased Largely.

Hayden, Stone Co. in their weekly market letter say:
 No more eloquent testimony in be- half of the wisdom of the safe of the Greene Consolidated Copper Com pany to the Greene-Cananea Com pany, and to the efficiency of tine Cole management of these properties, could be asked, than the simple fact which is stated to us in a letter writ ten from Cananea by our own cores pondent. In speaking of the changed conditions at the shelter of the Greene Consolidated Copper company he notes the facts that in the power room of the smelter seven boilers are now doing p per cent more work than was formerly accomplished by ten boilers, and the force of this department alone has been decreased by siXten men.
 He also notes the fact that just be- fore his arrival the second remod- elled furnace had been blown in. This process of remodelling will be con tinued until all eight furnaces have been dealt with. The new furnaces have a daily capacity of 400 against 25O tons for the old furnaces.
  been ordered, which will bring the total up to seven. Except for thh crushing plant, the concentrator seems to be doing its work well. A large extension, housing twelve van ners and six Wilfrey tables, has just been completed. Experiments have been made with a new type or table of greater capacity and supposed to give greater saving.
 The mines are far ahead of the smelter and could probably supply 25 per cent more ore than the present amount t2500 tons daily, if the smelt- CT were in condition to receive it. Here, also, the campaign of cost re duction has had a very noticeable ef- feet by the adoption of the slicing system in the place of the old square set system. The timber requirements alone have been reduced froms 2G feet per tone to If feet. With tim br at S23 per 1000 this is material saving. It is hoped to reduce min ing costs another one dollar per ton. This will be accomplished by the complete adoption of the slicing sys- tenn, the dipect transportation of the ores from the mines to the smelter by Ol them to bins and from there to smeft- CT by narrow gauge, as at present. and by the substitution of three cleo tric for seventeen steam hoists. When all this has been done mining costs ought to be very low indeed. Greene has none of the expensive or hoist ing of tn Bisbee camp, but little pumping as compared with the latter and none of the expensive rocK SC lection of Clifton.
 One has personally to go over the ground to get any idea of the enormi ty of the ore reserves. All the ore from the Oversight, the chief produc- CT, Is coming from above the first level. On the first, second and third levels, tremendous tonnages of good concentrating ore are being blocked out that may not be touched for years. No attempt is being made to get any show of production from the Cananea Central, and the output there at the moment is less than it was. All en- ergies are being concentrated on de- velopment, chiefly in the Bonanza shaft, which is down l5O feet and in good ore. There will be no material production from this property until it is in such condition that the ore can be extracted in the most econom- ical way
