 The three new southwestern dis tricts. in which Chino. Miami. Inspira. tion and Ray Consolidated are the principal mines. will add about 30 100000 pounds to the worlds produc- tion of copper this year, over IOO. .OOO.. 900 next. and, gradually increasing they should reach their maximum capacity in 1915 with an output of 2eo.e0e,000 to 225. .OoO, ,0OO pounds of copper annually. These mines. how ever, will furnish fully so per cent or all the increased copper produc. ton that will come from Arizona, New Mexico and northern Mexico in the coming five years, and probably nearly 90 per cent Of the whole worlds output growth for this period.
 Arizona is doing better on the low copper market than any other section Of the country. l figure that the Cop per Queen, Calumet & Arizona. United Verde, Arizona Copper. Detroit. Olo Dominion and Shannon companies will earn combined net profit of about Sll,OOO,OOO this year on a 121h-sent copper market. This will probably compare with net earnings of SS ,0OO.- 900 by the Lake Superior grouD Of mines: s7.S00. 900 by those of Butte: S6,00e. .00o by the Utah group, and Ss.7o0,eO0 by the copper mines of Ne Nada- Arizona is now producing about IT per cent Of the worlds copper. therefore. and getting more than 20 per cent Of the total mining profits
 On my three previous visits to the southwest heard a great deal Of talk in mining circles about the value of sulphur-iron ores. I was frequently told that if one had deposit of sul phide ores he could use it as the basis of a custom smelting business and make big profits on the treatment of practically unlimited tonnages of si- hcious ores. which were declared to be awaiting a market
 This fallacy has been exploded. At Douglas both smelters now have an excess of sulphide and iron, this being the chief reason for dismantling the old Calumet & Arizona plant and building a new one. Cananea, also. is in a position where it would like to buy silicious ores. United Verde has sulphide ores it would like to sell. Old Dominion is now getting all the sulphur it needs from it's own
 
 tons a day from Copper Queen. The only other shelter I know of that is buying ores is the Consolidated Arl- Zona at Humboldt. which are being shipped by United Verde
 All this excess Of sulphur and iron is failing to bring silicious ores to market This would seem to prove that such ores do not exist in quanti- " oS h,N l. shipped profitably with copper at it's present price. No large increase in copper production need be exected, therefore, from the silicious ore de posits-
 My visits to the principal old and new mines in the most prolific and prosperous copper producing district in the world has made me more bull ish on the metal market. Unquestion, ably the worlds output is going to increase; but the growth of output is coming almost exclusively from tho nsw porphyries. The older mines are not in a position to produce much more than they are now.
 Had it not been for the production of Utah Copper and Nevada Consoli. dated, during the past three years, there would not be a scarcity of cop per in the worlds markets and the price probably would be 50 per cent higher.
 In the coming three years the DOT phyries may be able to increase the annual production 270,000.000 pounds, giving this group a total output of 459.o0e. 900 pounds. The coming in. crease. therefore, will augment the worlds supplies by approximately per cent annually. Unless other mines are able to do as much more, making a 10 per cent annual increase alto gether, there is practically sure to be shortage of copper immediately after the existing surplus has been absorbed
 A revival in general business in this
