county:
 The most diversified mineral product l of Arizona comes out of Yavapai coun. ty. There are mines in the county that havc been worked since 1864, yet many of these older properties only now arc showing their best. This mainly comes through the development of the trans. portation system of the county. where railroads now tap nearly all of the more important mining districts, per | hitting tho reduction of ore that here toforc was thrown over the waste | dump. The Prescott & Eastern and it's extensions penetrate the Bradshaw Mountains, on the boldcst of cn. ginccring lines, and other Santa Fc branches reach out in other directions During the year it is expected that the Santa Fe will extend a cutoff line through the upper end of the Verde Valley, another section passing near Hillside on its way Co crossing of the Colorado River at Parker.
 Tho most important feature of the year for the county was the following in' of the Humboldt shelter, near Mayer. south of Prescott, the enter. prise meaning an investment of over $1,0O0.0o0. The plant has capacity for 1 500 tons of lead.silvor ores. and for 800 tons of copper ores. Another largo cop. per furnace is to bc added at once. It's product already is approximating l,0OO,00O pounds of copper bullion n month. The enterprise is wholly for custom ores. shipments coming from every part of tho Territory.
 Near the Humboldt smcltcr the Rig. by company has spent s200,00O in the development of chlorination and smclting reduction process under the Pohlc .Crosaalc process and it is be. lieved that the works will he able to treat especially refractory ores at n minimum of cost. In the same locality the Trcadwcll company has large smelter, unused. In the county are many smaller smclting plants, but 1t is now appreciated that only by combina ton can the most economical rcduc tion of copper ores be had.
 The output from Senator Clark :, United Verde mine at Jerome varic, much, according to the operation of th, great smelting plant, but is supposed {, return at least s5,000,000 profit veal to its owner. The yearly production of copper runs about 35,O00, ,000 pounds but the bullion is rich also in gold an, silver. Several of the best stopcs have had to bc cut off from the rest of th' mine, because of combustion in the sul phidc ores, but this condition has beer rcmcdicd by n pneumatic method latcl, tried. Connection with the Santa Fe Prescott & Phoenix road is had by ai extraordinary narrow gauge line, twen
 ty-thrcc miles in length. with ls
 curves in fourteen miles. The town 0 Jerome. while one of the largest in tn
 Territory, depends almost wholly upo
 the one mine for support. It is situ
 ated on the steep side of mountai
 that falls away sharply to the bottor
 of the Verde Valley.
 In the southern part of the count | q fln Cnn0vaaa yut,n x.t.ah one of the Territory's greatest gol
 producers. It has a reduction plant O so stamps, together with cyanid plant of remarkable size and of ex
 ccllent equipment. The workings ar
 the deepest in the Territory, two par allel ore bodies being developed to tn depth of nearly 1000 feet by half
 dozen incline shafts.

 few miles distant from inc Congress
 near the point where placer gold wa , discovered in 1863 by the Weave [ party, lies the well known Octave prop erty, developed 10 the depth of l ,s0' feet and equipped with iO.stamp mill A new company has taken hold of th, Octave, and will spend s200000 in de velopmest work. Near by, Prescott
 company is preparing to operate in Planet saturn property, in Fool [ Gulcb.
 A score of new reduction plants ar,
 being erected in the county, many o them for the production of eoncentrstc
 for final disposition to the Ilumbold 2 smeiier. Never before has there ! ~ei ! such n year for mining sales or ono il ' which greater activity has been know ! in mines. II is told tbnt sl ,200.O00 ha
 been raised by small companies fo development work around Jerome whore the Cleopatra company expects {,
 have small shelter working soon
