 in width are oxides sulphurets. The tunnel next above is forty feet; is ore of the same character every foot of the way. Tunnel No. has been run 140 feet showing equally with Nos. one and two. winze connects Nos. and f. the latter being llS feet showing fine AZurite. No. tunnel has been driven siXty-five feet and connected with No. by winze which shows the ore body to be continuous. On the Chrome North there is twenty five foot tunl>el showing ere running twenty feet copper and some silver The Chromes are joined on the east by the Azures North and South. which are being opened by an adlt tunnel To the east of the AZures lies the Hermit which has ore produced over 300 tons of ore averaging over twenty five per cent copper. This mine has been opened to a depth of eighty feet The Gift lies to the north of the Chrome North. The only development on this claim is tunnel which has yielded ore carrying fifty ounces silver per ton The company's furnace was blown in August 1. 1883, but owing to severe storms which prevented de- livery of ----.which run 1l9 up to January l. 1884. during that period the product was as follows: Copper. 2,00S,422 pounds; silver, 125. .000 ounces.
 During the month of Januray. 1884. but l4 days was had, producing. cop per- S1S,426 pounds; silver. 14,l24 ounces.
 In February, q days run produced S46S75 pounds of copper and 11,S22 ounces of silver.
 The winter snows making the roads impossible, the works were shut down during the month of April and the last l5 days in May the product was 33l ,091 pounds of copper and 23,464 ounces of silver.
 In June run of 30 days yielded 4ss.- 415 pounds of copper and 29,146 ounces of silver.
 The yield for S1 days in July was 500.000 pounds of copper and 9. 900 ounces of silver making the total dur ing a run of 230 days of 1000 tons of copper and over 225, 900 ounces of sil- yer. This showing for a 3O-ton furnace has never been exceeded, if ever equalled by any mining company in the United States. During the time mentioned over 1000 tons of ore has been reduced. The dividends so far by the company have amounted to ST. 800. Besides the clearing of these div idends extensive developments have been made on the different claims and a number of substantial buildings have been put up, including the hoisting works on the Hampton. The company has also built a new and shorter road to AshfOrk. on the Atlantic * Pacific railroad at a cost of Sl5.0OO About 75 men are employed in the mining and at the shelter. Superintendent Thomas and Governor Tritle were the first to give these valuable properties a thor ough examination and on their favor a Fl a organized. They are both experienced mining men. the governor having for years been connected with some of the leading mines of the Comstock MT Thomas has also had wide experience and combines in an eminent degree the practices and the theoretical knowl- edge of mining operations, being a graduate of the mining school of Yale and having been engaged in the pursuit for over twenty years. There is no finer mining property in Arizona than the United Verde. Its yield in the past has been phenomenal, and with high grade ore in every drift and stope it promises equally well for the future With the erection of another furnace and with railroad which Is now pro- Jected running within a few miles of the mines, the United Verde company will be able to lay down copper in the markets of the east at a lower rate. than can be done by the famous copper companies of the lakes. WHh abund- ance of rich ore in sight and with every facility for it's reduction the United Verde may confidently look forward to many q year en bonanza
 The methods of mining, evolved ! during the active period of develop ment by General Manager Chas W. Clark and assistant manager and Mine SuDerintendent Robert E. Talley. are naturally divided into three prin- cipal parts. viz. recovery of the oXidized ores underlying the gossan outcrop of the sulphides forming the main deposits and of the ores lying within the fire zone" writes C. A. Tupper, in the Mining and Engineer ing World.
 The system best adapted to each has been worked out gradually. at d minimum of expense compared with the results accomplished, and upon q thoroughly commonsense basis, which reflects great credit on the manage ment.
 'The ore bodies of the United Verde mines are in the form of lenticular ! lenses and occur in q large shear zone of schist and porphyTy. The country rock Is diorite and the schlst is an alteration of this rock. The porphyry IS silicious and is an intrusive in the schist. The ores are mostly chal- copyrite, except on the upper levels where considerable amounts of chal- ! cocite, black oxide and other second ary minerals occur.
 There are three principal classi- flcations Of copper ore. according to the gangue rock The first and most ! important is termed iron raw and assays from g to 40 per cent iron 1 35 to 45 per cent sulphur and from I to 10 per cent silica. The copper [ content varies from low to high grade ore There are immense lenses Of low grade iron pyrite enriched | along the lines of contact of the schist i and porphyry and along intrusions l locally termed water -cOurses"). 10 ' commercial ore. These ore bottles ex- tend 10 within 150 feet of the surface. [ over which oxide ores occur carrying good values in gold and silver and ! small values in copper The second class Of ores consist of chalcopyrite l in 2 schist gangue. and these ore bodies extend almost 10 the surface ] With but little alteration or enrich- ment The third class of ores are in d quartz and quartz porphyry and ! extend to the surface as an iron stained quartz cropping. Portions of this latter class of ore are so silicious that 1t is used for converter Tux Parts of the oxide ores over l lyilg the pyrites are also sufficiently sliicious for use as converter Aux. A large portion Of the old iron su- phlde ore bodies are in a fire district and are bulkheaded off from the re- mainder of the mine. except such portions of the fire area as Is now being worked as descrihad heIo,y
