COLO DEPOSITS lal ARIZONA.

nal of January 4. 1902, under the head ing of Gold and Silver in 19OO,' th' snflowing statement is made: The at sempt to reopen some of the old mine. ol Arizona while successful in some cases. has been failure in others, anc thH territory remains about where il sas year ago so far as gold produc uDn is concerned"
 Taking this statement as a text John Hyde Pratt, has written the followins ouncerning the gold deposits in this tarrIory, which will be read with unus. uai interest:
 This statment is true so far as act. aai production of gold and silver bull hnn is concerned; but it is far from be- ing the case when the actual condition of the gold mining industry of Arizona IS considered. There has been in the past year very decided and encourag- nng advance in the development of gold mining properties, and at the end al 1902 the results will apparent in me increased production of gold from this territory. There has been. and Is still, great deal of wildcat specula- eioI in the gold mining properties Of the territory, and in a number of cases supposed gold mining properties have been bought and companies incorpora- ted to handle them where the propert- S vas known to have little or no value These methods are, however, now con S,derably over-balanced by the devel- opmert of gold properties on a sound and substantial basis.
 Extending across the territory from sss southeast toward the northwest is An. extensive for nation of carbonifer- GUS limestone with which a great se- Vses of ore deposits are directly or In- aarectly associated. The principal rocks underlying this limesone forma- -.on ate g~aHites and geneisses. Other :scdt-nentary rocks, that are found as. sociated with the limestone, are sand zknne (which has in many places been entirely metamorphosed into quartz Te) and conglomerate. Cutting these sedfmentary rocks are large masses of eorphyritic rock, quartz porphyry, tra- -hyte and dikes of diorite.
 Tt is in this mineral belt that the zrge deposits of copper have been Sound The principal gold mines are tound in four distinct districts: One IS in the southeastern part of the terri sDry, III Cochise county. in the vicinity oa Tombstone. The principal mine of this district is perhaps the old Pearce, HEAT the town of the same name, and BOW known as the Commonwealth nIne-- Another district is in the vicin- ny of Tucson, where the mines occur thirty miles north and south of that 1fy- Still another is known as the Weaver Mountain Mining district. and st might be well to include in this the Rines that are found extending almost continuously in slightly southwest Erection from the Weaver mountains. fs this district would be included the celebrated Congress mine, the recently apned Cctaye, and the Vulture Forty Miles to the west of this district is the Aarqua Halla Mountain district, which includes the parallel range known as 1r Harcuyar mountains. In this dis tKict are located the noted Haraua Hal Ia mines, which give prominence to ehis section, now the scene of active mining and prospecting.
 There are a number of other places throughout the territory where gold has been found, but there is little sys- sematic mining now being done for gufd or silver in them with the except En perhaps of the Silver King mine. which is located in the northeastern part of Pinal county, and which has been one of the noted producers of the ssrritory. In many of the copper pro aucing districts more or less gold is found
 In all the districts referred to there IS a great deal of activity and strong companies are obtaining control of mines and claims with the intention nj developing them and, if possible making producers of them. The Weay sr and Harqua Halla mountain dis tricts. which were recently visited by the writer. were showing up some good properties and both gave promise Sf developing into regular producers T gold.
