Production of Copper in 1911.

the United States Geological Survey from all plants known to produce blister copper from domestic ores and from all Lake mines indicate that the copper output from the United States in 1911 exceeded that of 1910 and nearly equaled the record production of 1909.
 SHELTER PRODUCTION.
 The figures showing smelter pro. duction from domestic ore, which have been collected by B. s. Butler, of the Survey, represent the actual produc- tion of each company for eleven months and include an estimate of the December output. The November fig. ures for few companies were not available and these companies furn- ished estimates for the last two months of the year. According to the statistics and estimates received, the output of blister and Lake copper was l,09l ,554, 900 pounds, against l,OsO, l59, ,5O9 pounds in 1910 and 10 2,95l, ,624 pounds in 1909
 REFINED COPPER.
 Statistics showing the output of re fined copper by plants in the United States are not collected by the Geolog ical Survey at this time. Figures pub lshed by the Copper Producers As sociation for the first eleven months of l9l indicate that the production oi marketable copper by the regular re, fning plants from all sources, domes tic and foreign, will amount to about l,423, ,000, ,000 pounds. against l,453, ,O. O, 900 pounds in l9l'.
 IMPORTS.
 According to the Bureau of Statis, tics, imports of pigs, bars, ingots, plates, and old copper for the first eleven months amounted to PA, ,S79. .5O4 pounds, and the copper content of ore. matte, and regulus imported amounted to 63, 466,7S pounds. If the import, for December were equal to the aver age monthly import for the first clever months the amount of copper entering the United States for the year wa, about 336, 6,OO0,OOO pounds, against 344, 435,77l pounds in 1910.
 EXPORTS.
 Estimates based on figures for the first eleven months, published by the Bureau of Statistics and also by the Gunner Producer,' Association, indi. cate that the exports of copper will considerably exceed the exports oi 1910. and that they may be as nuci, as 75O.OO0, ,OOO pounds.
 STICKS.
 Stocks of refined copper held in the United States on January l, 1912, are probably somewhat less than on Jan uary l, 1911. and foreign stocks are al so less. Both domestic anG foreign stocks have been materially reduced since the middle of the year.
 CONSUMPTION.
 Statistics showing the domestic de. liveries for the first eleven months of the year, as given by the Copper Pro. ducers' Association, indicate consid. erable decrease in domestic consurap D. tion compared with l9lO It may, however, exceed 100000, ,000 pounds.
 PRICES.
 The average quoted price of cleo. trolytic copper for the year showed a further decline from the average for 1910, The average for 1911 was nearl, l2.4 cents pound, compared with 12.74 cents for l9lO Near the close of the year copper was selling at higi . CT figure, the average price for De. cember being materially above that for the year.
 Leading Copper-Producing States.
 ARIZONA.
 For 1911 Arizona again holds first place among the copper producing States, but the output will hardly equal that for 1910, viz, 297, 7,25O. .OOC pounds.
 The Bisbee district was the largest producer, with an output of about l33,. 000,00O pounds, marked decrease from the 142, 100000 pounds produced in 1910. A part of this decrease wa. due to the stopping of shipment by the Shattuck- Arizona mine during the later part of the year. Developmen, disclosed some new and important ore bodies in the district. The Calumet & Arizona and Superior & Pittsburg companies were consolidated and the new cOmnanv hepan the conStructio,
