 Prof. James Douglas in the Engin- eering and Mining Journal:
 The copper industry of southern Arizona during the year 1903 has been active and prosperous. The older companies have maintained their pro- duction, and of the new companies the Calumet X Arizona Mining com pany, the shannon Copper company and the Black Diamond have increased their output. If the two copper works in northern Sonora near the American line, whose output reaches the Ameri- can market over American railroads, be included ln the copper production of the southwest, the total production during the year 1903 is approximately s0,000 tons. Of this amount about 26,000 tons is due to the Greene Con- soidated Copper con papy and the MOctezuma company iu Sonora. The United Verde is not included; the production is supposed to be normal, and improvements at that niue aim at giving greater facilities for hoisting and handling ore, and counteracting the damage done by the fire which has for years retarded operations.
 The production of the Old Dominion mine has been turned out principally In tha f hff,h-nral. the Old Dominion is erecting new smeltering works with converter de- partment, it's production in the near future will reach the market, like that of all the mines of the southwest ex- cept the Black Diamond, in the form of bessemer bars. More radical im- provements are being made by the Old Dominion, both in the mining and smelling departments, than by any other of the older companies, with a view of raising the production to approximately 100000 pounds per month.
 In the Bisbee district there has been great activity, some two dozen com panies outside the Copper Queen be- ing engaged in more or less active development. The only one of these companies which is Increasing the Arizona production is the Calumet S Arizona, whose smelling works at Douglas have turned out approximate ly l2,000 tons in 1903. But another new company, the Lake Superior & Pittsburg, which bought the property of the South Bisbee company, has en- countered a large body of oxidized ore on the l,000-foot level, and will prob ably add somewhat to the production of 1904. The large Douglas works of the Copper Queen company will be in operation before the year closes, but though their capacity will approach 1000 tons day when running full, their supply will be drawn not only from the property of the Copper Queen mine, but from the Moctezuma Copper company's mine in Sonora, the United Globe Mines, and other properties controlled by the same owners. They will also be used as custom works for the smelling of copper and dry gold and silver ores, but not of lead.
 In the Clifton district the shannon company has almost steadily increased its output, which has attained an average of nearly 800 tons a month. The Detroit company and the Arizona Copper company have shown no in- clinatiOn to increase their output notably. The Standard company has been steady producer of high-grade | ore, which is handled by the Arizona | Copper company's smelter, and other mines in the same district are being | developed, with the probability of | main ntaining, if not increasing, it's pro. ductiveness. The ores, however, of Clifton and Morenci, where they exist in large quantities, are so lean, and | involve so heavy an expenditure in works, and the margin of profit per ton is correspondingly so small, that any rapid increase of production from that region cannot be anticipated. On the other hand, the size of the ore bodies is such that no signs of ex- haustion need be anticipated in the near future. The prospects, therefore, are that the contribution in 1904 will be slightly greater than in 1903, unless operations are curtaled by labor troubles, either in Arizona itself or in the coal mines whence Arizona draws her fuel supply, or by cataStrophes which one cannot foresee.
