at the Humboldt Mine
 Tbe Arizona Copper company is nov
 ,.,optng toequip the Humboldt, on'
 ' s,ts hest developed largest producing
 .,o,rtiss, with electric haulage ant
 Isn,rc tights, and with this end ir
 ,iew Chief Electrician Cox, with q ,,roS uf assistants, is now at work
 ,nttinr in the wires and making the
 sponnecttonS. The power will be sup
 y,,d from the LOngfellow concentra- ',,, nlant, and cabled to the mine at
 yorenci, distance of one mile. A
 ., horse power electric locomotive will ,, rsed for hauling the cars which
 ra, have a capacity of six tons each,
 n,rdIing about thiryt'six tons to the
 ,.,o There will be about two miles of
 ,,,,k in the mines equipped for electric
 r.rIagc. and the mines will also be lit
 ,,,tb ipcaudescent lamps. The lower r,ysIs will not be equipped for electric b,pIagc for some time yet, as the .,.,,t bulk of the ore is now coming from [ @ upper levels. The mine is noU nroducing about 500 tons of ore mar day, which requires eight mules and sixteen men to bring it to the sur
 ,cp and dump it into the ore bins. Nsarly all of this expense will 6e done away with by electrical haulage, and ha,ids, that the ore will b. hauled in one shift.
 A unnel has been driven through C,pper mountain on the Humboldt w,rkingS. after which the track cross A, the gulch and connects with tun- rsl on the Clay mine which has been d.iypn in several hundred feet. A rIant for air drills Is now being put in at the face of the Clay tunnel, which will bs used in driving this tunnel through the mountain, when 1t will come out on the other side at about rba head ut the Queen incline. When inc tunnel is completed the ores from the Queen mine will be brought out oyer the trolly line aud through these tunnels to the mouth of the Humboldt tunnel at Morenci, and conveyed from there to the LOngfellow concentrator by the railroad. The tunnel through The Clay mine will also be used for operating the CaraSco and other mines on the same mountain on which the Clay mine is situated.
 Arrangements are also being made in the gulch between the two tunnels to deSulphurize th9 heavy sulphide ores which are now coming from the CaraSCO mine.
 A new and large hoiSting plaut is also being erected on the Humboldt for operating its lower levels, which have now reached depth of 4j0 feet from the mouth of the tunnel, through which the great bulk of the ores are now handled.
 Work is progressing rapidly on a system of dams for storing the tailings from the Arizona Copper cOmpany'S ConcentratOr, which will be in opera ton in a short time. The tailingS will be dried, then hauled by cars back to the mines and used for filling the old workings. This will do away with tue annoyance of tailings coming down Chase creek.
 A new huiStiug rig is being arranged for the Yayapai, which will soon be in commission.
 The work of opening up the new LongfelIow7 at greater depth Is pro gressing fAVJrabiy, new levels having been run much lower down the noun tain, which are being connected by the older workings above. A new tunnel is also being driven in from Chase creek, which in tima, perhaps year or more, will be connected with the Longfellow workings, affOrding a new outlet for the ores, doing away with the hOisting plant and also open ing the mines at great depth.
 Arrangements are being made every where to handle au increased tonnage, and at less eXDanSp The manapement IS using every effort to cheapen the cost of mining and handling of the ores, and ere many months what is Known as the LOngfellow group, which Included number of prominent pro ducers, will be producing and handling Its ores for less expense than any other company in the Clifton Copper Era.
