Professor James Douglas in the
 Engineering and Mining Journal:
 The copper industry of southern
 Arizona during the year 1903 has been
 active ane prosperous The older
 companies have maintained their pro
 auction. and of the new companies
 the Calumet & Arizona Mining com
 pany, the Shannon Copper company
 and the Black Diamond have in
 creased their output. If he two cop
 per works in northern Sonora near
 the American line, whose output
 reaches the American market over
 Amel ican railroads, be included iE
 the copper production of the south
 west, the total production during the
 year 1903 is approximately S0,000
 tons. Of this amount about 26,00O
 ions is cue to the Greene ConsoLdat-
 ed Copper company and the Mocte- zuma company in Sonora. The
 United Verde is not included; the pro- aucuon is supposed to be normal, and
 improvements at the mine aim at siyIng greater facilities for hoisting and hadling ore and counteracting the damage Gone by the fire which has Tor years retarded operations.
 
 The production or the Old Dominion nine has been turned out principally an the form of highgrade matte. As the Old Dominion is erecting new smelling works with a converter de partment, its production in the near future will reach the market, like that df all mines ot the southwest except the Black Diamond, in the form oi bessemer bars. More radical improve nents are being made by the Old Do both in the mining and sme.t- fng departments, than by any other of the older companies. with view of raising the production to approximate ] iy 2,00O, ,0OO pounds per month
 In the Bisbee district there has been great activity. some two dozen com ,anies outside the Copper Queen be- ag engaged in more or less active The only one of these which is increasing thei srizona proGuction is the Calumet & Arizona, whose smelting works at Douglas have turned out approximate y l2,0v0 tons in 1903. But another lew company, the Lake Superior & statsburg, which bought the property r the South Bisbee company, has en- ountered a large body of oxidized ore n the 1,600-foot level, and will prob bly add somewhat to the production q 1904. The large Douglas works of be Copper Queen company will be in peratien before the year closes, but hough their capacity will approach ,O00 tons day when running full, 6eir supply will be drawn not only rom the property of the Copper ,ueen mine, but from the Moctezuma .opper company's mine in Sonora, the Enited Globe mines, and other proper les controlled by the same owners. hey will also be used as custom Lorks for the smelling of copper and ry gold and silver ores, but not Of sad.
 fn the Clifton district the Shannon fmpany has almost steadily in- ceased it's output, which has attained 1 average of nearly 500 tons onth The Detroit company and Ie Arizona Copper company have town no inclination to increase their ltput notably. The Standard com my has been a steady producer of gh-grade ore. which is handled by e Arizona Copper company's smelter Id other mines in the same district e being developed, with the proba- 1ity of maintaining, if not increas- E its productiveness. The ores, ,wever, of Clifton and Morenci here they exist in large quantities, e 50 lean, ard involve so heavy an penditure in works. and the margin
 profit per ton is correspondingly | small, that any rapid increase of oduction from that region cannot be ticipated. On the other hand, the e of the ore bodies is such that no ms of exhaustion need be anticipat-
 Tn the near future. The prospects, 'refore, are that the contribution in D4 win be slightly greater than in B. unless operations are curtaiIed
