 BIsBEE CrY, August 2S -EDrroR CITIZEN: Among your many articles Of interest to the mining fraternity, generally speaking, I ksow Of none presenting more glowing possibilities than are raidly being developed in our modest little camp. In my letter of last week, simply mentioned our ex- isience, fearing to touch upon the re- sources of our mineral belt, because oi the treachery of all prospects, and even now l shall await the result of further development ere making posi- tive statements.
 h all directions the work ol pros pecting is being pushed, and daily packs" arrive to finish assessments upon claims almost forgotten, till the erection and completion of Messrs. Martin & Ballard's furnace began to show forth what might be"
 As yet the Copper Queen is the only mine on which any real work is being done and upon this property must rest the honor of winning the success which now seems certain. Favored in every way by nature of its locality and surroundings, and also growing more and more abundant in its power of production with every blast, is it to be wondered al that the fortunate owners are sanguInc Uf theIr enter
 prise?
 The opening, as l wrote in my last, is only on the surface-a shelflike quarry of immense proportions, on the side Of the hill, some two hundred | feet above the ravine in which the | town will be built. Daily large ad- ditions are made to the dump, which already occupies so much space as to render it an inconvenience, and as yet there is but a ien-hour day shift of 1 twelve men employed. No defined
 ledge exists. The ore Is apprently vast deposit, having for Its base lime formation with associate parts of gyp-
 sum, manganese and other mineral
 properties, all heavily capped in iron and well iimbered. From the dump
 workmen wheel it to the upper end of
 the chute, where it is cracked into ] small pieces by a force Of eight men,
 this being also simply day shift.
 From the cracking dump II is sent flying dOwu the chute to the furnace feeders Co be mixed in the charge for
 smelling. Here again Is a shift of
 men cracking silica to be used for ! Aux. shoveling coal and coke, weigh ] ing the component parts and wheeling inc same Co the feeder of the furnace. : Thus far tbe ore has possessed very , high average, being 5 per cent. or
 over. Silica predomiuates everywhere
 and renders the slag very fluid and
 easy to tap, running off a jetty mix
 ture of waste which il ats abnve the
 copper.
 The furnace fed, We step below and
 are now in the canyon, long known as
 Mule Pass. Here are the engine
 boiler, blower, tapping spouts of fur
 mace, tank, slag-pots, moulds and al
 accoulremcnts f1r handling the metal
 The engine is a Berry & Place up right, of fifteen horse power. The blower is a Baker, No. 4la, with ca pacity of eighty revolutions. The shelter is the work of the Pacific Iron
 Works. built under the supervision oI Messrs. Bisbee, Williams & Co, anC is capable of smelting 30 tons per day Amid all the tedious delays of start ing. which at it's bestls an experiment
 the management are perfectly satisfied with the results. Running only hal capacity the net product has, at th enc of one week, reached 43,000 pounds of copper, O2 fine. At the furnace
 there are three eight-hour shifts, feed g CTS. and furnace men; also two twelve ? hour shifts of furnace helpers. The only real detriment to the CT [ tire satisfaction of all concerned wa Z the water supply, and now active pre- parations are being made to rende g this ob,tac.eya thing. of the past. Tn - only water ,hus far in the canyon ls spring located upon the miil-site owI !: ed by Messrs. r. and F. Corbin. Froi ,. tbis spring run two pIpcs of an inc e and a quarter diameter to a sluic' D WAY. thence 10 the tank, which has = capacitv Of 22OO gallons. The furnaC |. is of the class known among machiI r ists as a water jacket" having a inner partition of plates, against whic n the intense heat is thrown Dy II n blowcr. Between these and outC .s nlates is a continually blowing streai Q, of water from the tank, this reDderlr
 inc furnace much more durable ar 70 enabling il 10 withstand the utmo 70 pressure from the blast. In supplyin 10 inc jacket there is great waste al pre- n ent, requiring 2O,OO0g gallons. In a shC
 time. however, reserve tanks Will
 put in place and pumps will for

 Already two tanks, one 22O0 and tl ,d other. 5000 gallons, are on their WI .s here from san Francisco.
