METAL MINING IN ARIZONA
 FIELDS SUMMARIZED

oording 10 V. C. Heikes of the United States Geological Survey. department of the interior Arizona continued to be the largest producer of copper in the United States and will prob ably maintain it's position in 1919, b., with greatly reduced output during the first six months. when curtsilInent Of production followed the reduction in the prices of metal.
 The output of gold in Arizona in 1918 was 262.919.43 ounces, valued at $5,- 435,027. which represents consider able increase over that of the P 'yioLs year. The United Eastern and other gold mines in Mohave county which contribute the largest part Ci ths states output Of gold. continued to produce heavily during the first half of 1919. the grade of ores permitting mining under the prevailing high costs. ire Gold derived from copper ores, however. Will undoubtedly be much less !n 1918 ih.n in lYl>. for two of the ',,:2e mines ar'. .melters .ear JcrJn,s were closed for "a e. months.

Much copper in igno;s was piled in nearly all the smelter yards awaiting shipment, and only the greatly reduced current production Nas sent 10 he eastern refiners. Sov- tral Of ;hs smelling plants were closed :n ? Sh9nror in January and the Sisco United Verde and United Verde Ex- tension in February though the last two resumed operations in May and June The mines were producing a, ou.rut in 1918. The monthly 2rocuc- tion Of the Inspiration and Miami! companies was close 10 tha; of the pre- v.cus year. but the Ray Consolidated was making about half its former out pu. there was general scarcity of return of the troops failed to meet the demand; but the curtaiiment has per Initted mine development and repair and construction of furnaces after a period of forced production. One of the interesting features of the work the continuation of stripping by stream shovel on Sacramento Hill at Bisbee. The United Verde began work with steam shovels 10 uncover large body of low grade ore and kept large force o. men making extensive i'm pTovemen,s and additions to the ca pacity of the new smelting plant al Clarkdale At Ajo. the New Cornelia Cooper company plans to construct a 50o-ton experimental Notation plant for it's sulphide ore, and at Ray :le rev mill of the Ray Hercules company was treating about 800 tons of low grade ore day.
 The output of lead in 1918 was 12.- 5O3.Sss pounds, decrease from g.. 4S5.445 pounds in 1917. As the price was only about cents a pound in
