saving only 32 pounds of copper to 15O.OOO pounds of copper each day. or 57.000.000 pounds annually. Assum ing a cost of nine cents pound, with copper at thirteen cents in the mar ket, will give an annual profit of s2,- 304,O00. As this rate of production with the present developed ore body means an approximate life of thirty years, there is revealed the astound- ing total profit during this period of about S69, ,129,OOO These are only rough figures but they serve to indi- cate somewhat of the magnitude of the project now being carried on by this company.
 The Gila and the Ray Central, the latter another Lewisohn project, are now undergoing development of the most active description. The Ray Central is confining its operations at present to a group comprising a trifle more than twenty-nine acres and have just installed one 150-horse power boiler, while a second of equal power is now being erected. These boilers will operate the double drum hoists at the Madeline, and the Globe shafts which have penetrated the blanket ore body that underlies the properties of the Bay Central and the Gila com panies. A concentrator will be in stalled on the Ray Central inf the near future.
 In Cochise county. aside from the vast operations in Bisbee. the most noteworthy recent development has been at Courtland. where the Calumet and Arizona. the Copper Queen and the Great Western companies are operat- ing extensively. Last February this camp was practically a desert. Today it's mines are shipping ores to the smelters at Fl Paso and Douglas, while hoisting machinery and an cleo tric power plant, railroad spurs and all other essentials of a thriving mining town have been installed. The compa- nies now operating there are noted for their skillful management and thorough knowledge of copper min ing as exemplified by their past sue cess at Bisbee. and there is every req son to believe that Courtland will soon
 
 ble copper producers of the territory
 Of the gold mining properties none holds better prospects for the future than the old and famous Vulture. To- cated sixteen miles southwest of Wick enburg in MaricoDa county. This property was'taken over about eighteen months ago by a powerful syndicate of Boston and Montreal capitalists, who are now putting the mine in shape to become one of the great producers of the southwest. when it is probable that the past record of s16.O00, 900 produc- ton will be largely exceeded. At one time the property of former Colo rado senator. who was compelled to let go of it owing to financial re- verses, it is now in the hands of one of the wealthiest corporations working ing in Arizona. with q capitalization of $3,0OO. 900 divided into 500, ,000 shares of 8 each. of which less than 100000 shares have been issued. Plans are be- ing perfected for the erection of q 100- ton stamp mill to cost in the neigh borhood of $20O.OOO, and it is expected | that the contract will be let for the 1 erection of the first unit of twenty . stamps MliflH tue next lNp pl NLAAtN weeks The other units will be ad- l ded as development justifies.. Three new levels have been opened up be- low the old workings, the lowest level now being 500 feet. The mine has been thoroughly overhauled and put | in shape for economical and safe oper- ation and the ore body will be opened up in the most systematic manner pos | sible. The ore now being run through the twenty Stamps of the old mill aV- erages s14 per ton, of which So per cent of the values is recovered by amalgamation A cyaniding process has been especially devised for treat | ing the ore in the future which 1t IS ! expected will save about 95 per cent of the values.
