the increase in the shipments of sil- ver-Iead ores also contributed to the increase. The silver production from zinc ores and iead-zinc ores is not great, but silicious ores in Cochise county supply a material percentage The Commonwealth mine at Pearce was treating approximately 10000 tons of ore month, making bullion con taining principally silver At the Tombstone property operated by the Bunker Hill Mines company. ore and tailings were being treated by cyani- dation toward the end of the year Work was resumed at the McCracIen silver mine in the owens district of MohaVe county, for which mill is planned.
 Arizona is the leading copper pro ducing state of the country and had an output of nearly 45O. 900 900 pounds in 1915, an increase in quantity of nearly 57,OO0, 900 pounds and in value of nearly $26,00O, 900. In the latter part of 1914 many of the copper mines had been closed or worked on a 50 per cent. basis. As the price of copper increased in 1915 from 1860 cents a pound in January to 1915 cents in June, mines and smelters took advan- tage of the rise in price and toward the end of the year were producing at more than the normal rate. Great increases were made at the smelting plants at the Calumet & Arizona, Cop per Queen. United Verde. Hayden, In ternational at Miami and Consolidat ed Arizona at Humboldt. The new plant of the International $. &; R. CO H-0 ct a rta in nf and treated concentrates from the Miami Copper company. The new smelter of the United Verde was blown in May IS and the old shelter closed August 21. On account of floods in April. the old Dominion plant did not increase it's output for the year. and on account of the strike in the Clifton MOrenci district for Sep tember the output of the DetrOitAri zona Copper and Shannon smelters was greatly decrea sed. At the InSpi- ration property the new mill, using concentration and Notation, was treat ing 5000 tons a day in october. The Ray Consolidated. during the first three-quarter sof the year, produced nearly 44.OOO00O pounds of copper, or al the rate of a little less than 5000, 900 pounds a month.
 
 increased from 15,OO3O6S pounds in 1914 to about 22.272. 900 pounds in 1915. an increase of over 4S per cent. The value increased from $5S5.l20 to $1. 1.O33, ,OO0 The greater part of this output comes from the Copper Queen and Shattuck properties in the War ren district in COchise county The Tennessee mine in Mohave county produced a lead-zinc ore treated at Needles from which lead concentrate and zine concentrates were shipped
 The mine production of zinc. esti- mated as recoverable speltcr. increased from 9.792 .337 pounds in 1914 to about 17.729.OOo pounds in 1915. an increase of S1 per cent The unusual average price of zinc for 1915 gives a value of about $2,524,O0O to this product It came almost entirely from the Golcon- da and Tennessee mines in Mohave county. few other zinc shipments were made from Pearce and Hereford, in Cochise county: Casa Grande. in PinaI county: Red Rock, in Pima county. and Crown King, in Yavapai county The Texas Arizona property in the Cochise district. and the Du- ouesne property. in Santa Cruz county, also made a few shipments of zinc ore.
 For the first eleven months of 1915 the metal mines of Arizona contrib uted nearly s11.OOO.OoO in dividends. The principal dividend payers were the United Verde, Miami Calumet SS Ari- zona. Ray Consolidated, Superior X Pittsburg. old Dominion, Shattuck, Arizona Copper United Globe, Tom
