 The Coconino Copper company, who are operating in the Buckskin noun. tains, north of the Colorado river, in this ounty, are putting in teaching plant. They will use the Nealpro. cess, and they claim that the ore can be worked with very little loss by this process.-Sun.

The only strain will be on their consciences, when they come to Jnake their proof of labor.-Lordsburg Liberal.
 The big copper mines of Arizona are none of them very deep. The deepest workings of the Copper Queen are 1000 feet, and of the United Verde $50 feet. In these mines most of the ore taken out is from points above the 700 foot level. The extreme depths given represent late development shafCs.-B )sJDn Journal of Investors The Old Dominion, Globes oldess and best copper mine, is opened to a depth of only little more than $50 feet.
 The Calumet X Arizona mining con- pany, whose mines are at Bisbee, Las decided to build their shelter at Doug las. Contracts are to be let at once and the work rushed with all possible haste. Mir. Tenner, an official of the company, informed the Review that they would not build d large plant to start with, but would erect one fur mace of 25O tons capacity and two con verterS, and they could easily add to this as they saw fit. The Mine and Shelter Supply company of Fl Paso has secured the contract.
 Now that the storms of winter are on us the miners of the mountain states are drifting towards Arizona, where they are sure to find an agreed ble climate, and the greatest stretch of minerali7ed country on earth. Every mineral known to the the sci entlfic world is found in Arizona. The hardy prOspector will find the hills scanned and ribbed with veins bearing precious metals and realize greater re- ward for his labOrs than in any other region on the globe. The territory is large enough to accommodate all comers.- Mohave County Miner.
 When an ore deposit occurs in massive rock like granite, porphyry of any Xii nd, felsite, andesite, etc., and there is found an extensive crushing of the country rock along and includ- ing the vein, crOsscuts are of utmost importance, for the best defined wall often proves to be merely plane of fracture within the mineralized zone, beyond which pay ore may be again found; and because a crosscut in one portion of the mine is without result, should not deter the management from making others elsewhere. Cross cutting should be carried on system atically In view of this conditiOn.- Gala. Mineral Wealth.
 A miner gives a tabulated method for calculating the cost per ton for sto- ping ore in ordinary ground. Taking as basis the thickness of the pay streak at the point considered. as fol- lows: Where the ore streak is inches thick, the cost of stoping per ton, s17. .33; where 6 inches thick, $l1.. 5 per ton; inches, S7.67; 10 inches, s5 93; 12 inches, s5.78; II inches, s495. It would seem difficult matter to prepare a table which would show the approximate cost of stoping which would have general application, for the reason that the rocks enclosing the veins may be hard or soft and many other conditions, always differ ing, may obtain which have an i'm portant bearing on the subiect.-M. x E Review.
 Capt. J, H. Tevis, the pioneer Ari. zoniau of Lewiston, has recently made a wonderfully rich gold strike in one of his mines south of Bowie, in the Tevis mining district. The ledge is a very large one-more than 75 feet wide and the assays run as high as s2O0 to
