face of the ore pile. being equipped With an electric motor for the pur- pose.
 In depcsiting the material upon the
 beds from the overhead ore carrying tripper, the coarser pieces naturally go 10 the bottom of the pile, and
 here is also mixed in a certain DOT tion of low grade reverberatory siag, which adds 10 the effectiveness of the
 mixture for smelling purposes.
 The reader can readily see where a
 very great saving 2 ore handling over ! the old method is saved by this new plant which is one of the most per
 feet of it's kind to be found anywhere.
 There is an extra travelling bridge
 with it's motor. which can be put into
 commission at any time in case of de-
 engagement of the one in use. Every thing works with clock-like precision.
 there being no stoppages. The big
 drag. or harrow. with it's teeth and scrapers works back and forth across
 the face of the pile, the ore is brought
 before the steel blows and is scraped upon the belt without any lost motion. or words or excitement. It is a steady
 business. and the big belt with its end less load. travels smoothly and quietly bearing it's values to the smelters. i'm pressing one quickly with the ingenu- ity and value of the plan.
 Big Saving of Labor.
 The same smooth delivery is noted at the mouth of the furnaces where the charge is automatically delivered into hoPpers connected with the
 stacks. Here the ores may be run directly into the furnaces. or upon the feed floor in front, according to the needs of the tenders. The coke is handled with equal facility. There is
 being handled tonnage of about 10.- 900 monthly from the mines, of which about 30 per cent is direct smelting. the balance being concentrated. This volume is carried on those endless
 belt conveyors easily. Giving the
 reader some idea of the saving of men on the feed floors alone, two hun dred and fifty compared with the old number. aFe' dispensed within twenty four hours This shows what i'm provement in ore and fuel handling means to the company. and this is only one item in the many entering luAt tue tOHl. Altil iOl A4tAlN tA-dEatiA in this department have been trans ferred to some of the new mining properties of the company, or put at prospecting work at various locations.
 The Greene Cananea company has new lo0-fOot reverberatory furnace treating it's Hue dust and fines. The waste gases from this furnish 750- horse power, or 1000 engine horse power. The power hoGse of the old days, where men were so thick they touched one another in their move ments, and where eleven boilers were worked to top capacity to provide the needed steam. is now very quiet room. only three out of the former eleven boilers being in operation. Not only does the reveTberatory les sen the cost of treating the fines and flue dust. but 1t creates a wonderful energy for the waste gases. providing, as We have stated. 1000 engine horse power to be used in driving the ma Chinery Of the new plant. It can be seen al a glance that this amounts to a very large sum daily in the opera ton.
 It is such a furnace as this that Messrs. Powell and Wood, of the Cal umet & Arizona company are consid- in an article OF Bsbee last week.
 Entire Change in Shelters.
 The old smelteT plant of the Greene Cananea has been entirely replaced with new work Even the old steel building containing the former equip ment has been in part remodeled, sec tions torn away and replaced so as to better the light and ventilation. There are eight new furnaces, six Of which are in operation and producing more copper than the old eight. There are five stands of converters which are new. twenty new shells, a new feed floor. feeding devices, slag pots, bull lion dock and pumping plant. The runway and cranes have been rebuilt Shells are handled by electricity, one operator controlling the work Of this class in the entire room The McDouglal roasters have ! been completed and furnish sufficient | ,alcies to add to the fine flue dust to ! bring the reverberatory up to it's | capacity.
 Due to these improvements the | laily pay roll at the shelter has been about s1,160.00. which is a ' very big saving, and indicates the being introduced. Of the saving in all departments. mining. milling, smelling, etc, it will -un much above sl00,000 per month, 50 the local organization has been 7ery busy in the right direction ac- wonders, and putting the in shape for the keenest in its line. There have llso been concessions secured by the ,fficers of the company which amount annually to a considerable sum, and activity even in these ines when the market is lamentably ow Combined with the savings in he plant it means much to the com ,an-.
 Big Compressor Getting Ready.
 Al the time of our visit the founda- ion for big air compressor was re- eivine its finishing touches. The 'oilers were .on the ground. and the compressor was at Naco. Arizona, gaitinr shipment across the interna. ional line. This compressor will fur. fish 6.060 cubic feet of free air and vill replace many smaller plants To- ated al different points about the
