 high grade ore. principally gold. Is given over to surface mining. while various other systems are applied for copper. It Is understood that tseam shovel method of mining will be in- troduced shortly on the upper level and fire stope ore bodies.
 For nearly thirty years this mine has been producing, it's earning have reached the 50,000.000 mark, and yet greater plans are being made for it's development The United Verde Com pany has been termed the best man. aged and most self-contained in the world.
 It is interesting to contrast the early report of the mine by Patrick Hamilton in Resources of Arizona" to C. A. Tupper's summary of the mine. which appeared in the Mining and Engineering World.
 Following is from HamiltOn's books:
 Property of the United Verde Cop per Company is situated on the east slope of the black hills about, thirty miles northeast of Prescott. The company has constructed a road over the mountains to the smeter. a dis tance of eight miles away. at a cost of S40000 The first reduction ma chinery of the company consists of a
 
 CT and blower Water is piped to this from spring a distance of 2l4 miles at a cost of S10.000. The sup ply is ample for all demands Adja- cent 10 the furnace of the company are store rooms. blacksmith shops were built The shelter is connected with wagon road by tramway and the tramway connects the various mines with the furnace. to which the ore is tanFr 1nI boarding house, assay office, etc. are in close proximity to the works The company was incorporated in March, 1883. in New York. The officers are President Chas. A. Mcdonald Mana ger the Queen Insurance Company; Secretary and Treasurer Eugene Je- rome; directors. r. A. Tritle. Arizona: Chas. Lenning Philadelphia: Mir Bushnell N N.. Chas. A. Mcdonald. N. Y; Eugene Jerome. N. Y; F. F. Thomas is the superintendent Prop erty of the company consists of eleven claims and three mill sites situated on the east slope of the Black Hills, four miles west fo the Verde river. The formation of the rock is a Meta morphic slate on the east and on the west DiOrite and Quartste. the sum- init of the range being topped with lime. The Venture North and the Venture South and 2l5 miles south or the shelter The Venture North has been opened to a depth of go feet and carries ore that goes 5 per cent cop Der, also Quartsite and Malchite and Oxides. The vein covererd feet. The Venture South has a tunnel of 70 feet. following the ore body.
 The Eureka upon which most of the development has been made. is on steep hillside affording every advan- take for working through tunniels I. IS a large vein averaging from 20 to so feet of copper ore. A tunnel has been driven through the mountain from the north of the claim a dis tance of 2s4 feet. at a distance of 140 feet from the mouth of the tunnel q crosscut of l5S feet was made all the way in rich matter. At this point a body of sulphide was encountered 80 feet wide. averaging 30 per cent. From the surface a verticle shaft has been sunk connecting the crosscut where rich ore body was struck The shaft is sS feet deep and the last 40 feet in ore. At d distance of 50 feet south of the main crosscut another was run easterly some 50 feet south. all in ore very rich in silver.
 At the extreme south end of the tunnel still another cross-cut has been made for sixty-five feet easterly and six foot ore body exposed that as says twenty-five per cent copper. From the south end of this level a crOSs-cut has been run siXty-fiVe feet. The last five feet in fine ore. The upper level is connected with the main tunnel ty two shoots through which the ore Is passed into the cars on the track below and then run on to the furnace floors. An open cut sixty-five feet above the main tunnel and 105 Feet from It's mouth SHOWS a body of ore eighty feet wide assaying twenty five per cent copper and about twenty five ounces silver per ton. but very little stOping has yet been done in this magnificent ore body: nearly all has been worked, having come from delft levels and cross cuts.
 The Wade Hampton is located inn mediateIy north of the Eureka. Its ore bodies being a continuation oi those in the last named mine The developments consist of a tunnel eightyfive feet in length from which two cross-cuts have been run. The first cross-cut has been mode under the croppings which stands from thirty to forty feet above the surface The ore from this cut runs from twenty i've 10 thirty per cent copper with considerable gold and silver Double compartment working shaft has been put down to l50 feet, and sterm hoist ing works have been erected capable of sinking 800 feet. From the bottom ot the shaft there is a drift in a north eriy direction of forty feet. showing a fine ore body. but owing to the unsafe work of the ground work was sus- pended in this drift. A westerly cross- cut has been made from the main shaft distance of twenty-five feet and from thar point deifts have been run north and south. The north drift is seventyfive feet the last sixty feet in ore. From the face of the drift a cross cut was run east forty-seven feet all of the way in ore going from fifteen feet to eighteen feet copper and eighteen ounces in silver per ton. The south drift is 320 feet in length which carries t Into the northern end of the Eureka ground. At a point about seventy feet of the face of the soutf drift. a crOss-cut has been run east about thirty feet The ore averagine twenty feet copper all the way. tht depth of 100 feet at the main shaft q level was run north in which ore was struck forty feet from the shaft. This ore body has been thoroughly exploited Tor length of ninety feet. width o1 fltty feet and q helghth of thirty feet rms level IS now 2l0 feet from tn, shaft still in orc. Near the end ol thIs level an upraise of sixty-five ex- posed rich body of green carbonat, ore averaging thirty per cent copper About twenty feet from the main shaf Is the discovery shaft of the Wad. Hampton sixty-eight feet deep. From the bottom of this shaft there is { drift north fifty feet, thirty eight feel m all. From this point a cross- GU was made 10 the west wall twent,
