The Arizona Commercial Copper com ipsnv. whose property is located in the Conner Hill mining district and about four miles east of Globe, continues to |emplov about 300 men at it's mine and smeItcr. The smeltiug plant IS putting |put its usual amount of 50 per cent cop Rper matte, this output being about fwentv tons daily. The matte is ship bed weekly to the old Dominion smell Her. where it is treated by the convert snrs. Assistant Manager John F.. Penn fberthy is in general charge Of the Ari- koua Commercial mine F.. l.. Williams l s superintendent of the shelter.
 The management of the Arizona Com suercial Copper company is now hasten tng the work of installing its pumping A5lant on the sixth and seventh levels sDf the Eureka shaft, preparatory to be- 4ginnlng crOsscuttiug and drifting on I he seventh, where the shaft is only a khort distance from the Black Hawk Hedge, which should yield large quan- 4ities of ore of good commercial grade As soon as it can be opened and mined. 1.-Two pumps are now working on the k NlN ltNfl anu dlN udhAlAhE tA''"A - 2OO.OUO gallons of water every twenty -Four hours. A new 1000 gallon Pres tott pump of triple expansion and di- Rect action is now being installed on the seventh level and as soon as this Rork is completed, which will probably De about January s, 1910, the two crOsscuts which have already been be- gun at that depth will be extended. These crOsscuts were driven a short dstancc before the pumps were put in fo avoid having the pumping machinery Injured ny flying fragments of rock From the faces when shots are set of. 'These two crOsscuts have rather sharp cprve before reaching the Black Hawk ledge. The west crOsscut is twenty feet long and the east one is ten feet .oot from the station on the 7O-fOOt ierel.
 Drifting on the vein will be done From these erosscuts both north and As,alth of the shaft. The Black Hawk le6ge was cut by the shaft at a point IRtween thirty and forty feet above sne seventh level The ledge dips to tbf southward at an angle of about 53 degrees. The direction of the vein ir q llNlOhb uuc tdSl ana west.
 nwO winzes hse been started from tke drift on the sixth leevl. One of these winzes is located about 800 feet east from the shaft and the other has been ppt down near the Black Hawk shaft, which is approximately 900 feet instant from the Eureka, through which an the ore and waste from the mine is being removed. The east winze is about forty-five feet deep and the west one IS forty feet in length. In both of these winzes good commercial ore has prevailed all the way down and the material taken from these winzes has gone to swell the supply being mined for the shelter. The Arizona Conner. cial ore varies widely in copper value ag 8, of course, the ease in almost any mine, but it is a conservative state. ment to say that the average is about per cent copper.
 n ls rather remarkable fact that the machinery and equipment, both in connection with the shelter and the new power house and crushing plant Wmfh the Arizona Commercial Copper fQm any has had installed within the past six months has run smoothly from Ire start, making record rarely para. lieied and one that will be appreciated by pnen familiar with mechanics and witn the number of adjustments and
