Show WORLD'S SUPPLY OP COPPER1 I America Furnishes Over Half and Her Production. Is Increasing. Tho dovplopmcnt of tho electrical Indus-j tries of tho world In tho last few years has created a tremendous demand for cop-per, cop-per, very much as the need of rubber for bicycle, buggy and automobile tires has enlarged the call for the latter material. More than half of the whole product jH comes from tho United States, In spite of the fact that the production (and con-sumption) con-sumption) has doubled In ten years. Eight other countries which havo long been con-. tributing to the supply aro unable to-l IH gethor to match tho output of the United IH States. In 1F01 Russia produced 10.700 tons, IH Canada, 19.1S5. Germany, 21.015; Chill, CO.-110; CO.-110; Australasia, SI, 1C0, Japan. 3-1.S50; Spain and Portugal (which are always grouped together, hecatiso cortaln rich de- posits He on both sides of the boundary between them), 47,035, and Mexico, 50,915 tons. Mexico, which forced her way up to tho second rank In this group in 1902. obtained the first position last year, thus displacing Spain and Portugal, which long. had tho lead. This shifting- of positions' was partly due to tho Increase In Mexico's yield, but also to a falling off In that of Spain and Portugal, which have several times produced moro than 00,000 tons a year. The total yield of tho clcht countries justj H nnmcnJ amounted In to about 143. OX) tons H and that of tho United Stntco to 160.000. In 1900 the others together produced about IS?,-COO IS?,-COO tons and thin country not far from 250,000. In 1904 thalr combined output was 2-iS.OCO tons and ouru 331.170. Tho world's supply last year was about 012.000 tons, small reinforcements 1 fiom a number of sources, amounting to near- H ly SO, O0, belnc added to tho production of tho countries tpocllled. Ton yenro before tho pro- H duct scarcely oxectded 300.000 tons. H For a long tlmo tho chief production In tho United States camo from tho southern shore of Lako Superior, and more than half was ' credited to tho Calumet & Hecla system of mines. Montana llrst and then Arizona com-potcd com-potcd with uppt:r Michigan for tho leadership. As loni; uko as ISO I tho Lako Superior region produced ul.000 tons of copper (of which 30,675 tons camo from tho Cnltimot & llcola mines), Montana closo to 0,000 tons, Arizona 19.6V0-' nnd all other Stntcu and Territories togethor " M a modcKt 9000. Last year Calumot & Hecla produced 35.270 tons, tho other lake, mines 07,- 030. Montana llO.COO, Arizona 81,750 and tho other StatCB nnd Territories 40, COO. Arizona doesi not yot qulto match upper Mlchlcun, whoto product woa ovor 92,000 tone Still lees has fho caught up with Montana, but tho growth of her yield In tho last ten years Is elmply wondorful. It has been quadrupled, H whorcos neither Montana nor Michigan has H doubled ltn production. H |
