Wonderful Progress Made at Prop
 ertY of Sonora Copper Go.

the Sonora Copper Company, wonder full progress has been made in the way of developing the mammoth ore bodies and for the Improvement and better menG of the camp, which is possibly the most pleasantly situated of any in place can copper be produced at less cost than here, owing to the natural advantages and the economical system of developing the mine which now is down eight hundred feet below the sur face, a double compartment shaft be- ing sunk in tunnel No l to reach water level possibly at depth of niu @ hundred feet
 Accompanied by MT. N J. Purcell, the mining man, who is also a stock holder, the writer and Manager Con ard went to the bottom of the shaft to witness the operation of the machine drill, four of which are used in the mine, all hand drills having been cut out. In the bottom of the shaft we saw five feet of as handsome copper gold silver ore as ever came from mother earth, sornite and chalcopy rite, assay returns of which gave better than fifty per cent copper. and good gold silver values to the ton. This latest strike of sulphide ore is the most important yet made in the great Oobre Grande, where according to Manager Oonard, three hundred and fifty thous- and tons of ore have been blocked out, actually in sight, to the 400 foot level, alone.
 It will take about ninety days to reach water level and make upraises connecting tunnels Nos. l.2.3,4 and 5. when all ore from the upper levels can be delivered by gravity through tun-' nel No. l, direct to the smeLter, which will be shortly erected near the mine, from where tramway will be run, the survey for which having already been made by H. Gordon Glore, the we'll known mining engineer of this city.
 During the year just passed, many improvements have been made at Oobre Grsnde, among which are a large commodious office and we'll sup piled store building. two story hotel. residence tor manager and numerous buildings supplied with water and el ectric light for the miners, most of the buildings being made of adobe brick In the way of mining machinery large gasoline hosting engine and steam pumping plant has been install ed at shaft No 2. At tunnel No. are two sixty horse power boilers and 8 splendid Sullivan ar compressor for operating the machine drills.
 At tunnel No.l are also two Vest lnghOuse generators which furnish light for the entire camp and mIne in W hich there are more than two miles of underground workings. ngineered in such a complete manner as to make handling of ore from all levels. cross cute, sh sfts, winzes and upraises one of most simple economy, which taken in connection with the character of ores carrying lime, sulphur and iron guarantees the production of copper at very cheap cost. The generators also furnish power for the hoists at winze in tunnel No. l.
 Just as soon as the smelter which will have daily capacity of IO0-tons, costing about $75 1000 gold. is install ed stock holders of Sonora Copper Com pany should commence to receive handsome dividends. and the price of stock take an upward bound.
 Beside the Oobre Grande with it's hundreds of thousands of tons of prov on ore reserves, the company owns the town site of Noria and twelve thous- and acres of valley land around the mine and town site, three miles from the mine. The climate at Noria is ideal, mild in the winter and pleasant in summer. oranges being grown oD the line of the Sonora railway both north and south of Noria. splendid loca- tion for colonization.
 Moral and sanitary conditions at Cobre Grande are excellent, thanks to Manager Cohard's thorough system,
