need De no Immediate alarm as to a heavy decline in our copper supply While even such large reserves as the Calumet & Hecla once had in con glomerate beds are within measur- s.s;!!s assssalSo 0f exhaustion, others or the companys mines on the Osceola and Kearsage amygdaloid promise to enable 1t to maintain it's output. and the success of the Wolverine and Mo l hawk to the northeast of Portage Lake. and of the Baltic and other mines on the Copper Range to the southwest, are prophetic of what will gradually happen as the vast area of the amygdaloid and conglomerate beds which circle round from the Ke- weenaw promontory through Wiscon- sin into Minnesota are explored, They are so buried under forests and soil that their development will be slow. but the possibilities hidden within them are, are incalcuable. Montana which heretofore has meant Butte has held her own simply by Increasing her concentrating and smelting facilities to compepsate for the gradual decline in her ores: but discovery of large copper bodies at great depth below the argeptifer- ous ores of the North Butte mine and or others within what was considered formerly as the silver zone. and also to the south and east of what WAS once supposed to be the limit of the copper zone, may extend the life of Butte indefinitely beyond the limits assigned to it even by the most en- thusiastic supporters: and Butte will not be the only copper district of Montana, though probably none as productive will ever be discovered.
 Arizona. which has , made more rapid strides of late than it's com petitoTs. owes its progress mainly to the remarkable mining developments Tn The ltmestones of the Warren dis and as yet. the limit f these large and as yet. the limits of these large deposits. either laterally or in depth mas not been determined. In the Cliff ton district. the very large quantities or Iow-grade ores which support the Arizona Copper company. the Detroit copper company. and the Shannon and other minor companies, show no signs of exhaustion. Other deposits of the same general character and of great magnitude. in Mineral Creek and elsewhere in Arizona, and in the Burro Mountains in New Mexico as sure us of a sure supply, if not a very rapid increase for some time to come from the Southwestern States. This assurance is confirmed by the rapid growth of the mines in the neighbor- hood of Globe. and from the produc- ton Of the large number of small mines in the southwest, many of which are producing, and all of which are appealing to the public for sup port. The experience of the past year warns us. however. that the period of rapid expansion has passed, and that as the home demand will probably not fall off, we shall have less of our own copper for export than formerly. But this deficiency will probably be supplied from for. elgn ore or metallurgical products treated in our furnaces and refineries. Last years statistics show an impor- tation of foreign copper, partly in ores. partly in matte, and partly in unrefined bars, of 136,826, ,906 pounds. Most of this was from Mexico, some from Canada. some even from New Zealand. It is to the credit of our smelters and refineries that so large a quantity of copper should seek our shores for final treatment, some coming even from British colony at the antipodes. This is due as much to their business methods as to the e1CPIIgnCy anu -gCUHUnTy or then T1etatiursic work. The scaie on which they work is liberal. and that is one reason why their scale of charges is attractive
 The ''Asineral Industry for 1906 gives the amount of electrolytic cop per turned out by nine electrolytic re- fineries at S65, 100000 pounds. and their capacity. at 1,120,000, 600 pounds Distributing tine actual amount re- fined proportionately among the re fineTies, if the capacity of each is cor rectly given. the production of each is as follows:
