tory and continued good management ' Will make it's owners rich, make the rapchers on the San Pedro happy and the business men of Tucson will vel. como the trade that is forced this way.
 The Mammoth mill started with 50 stamps last Tuesday sSter being oyer- hauled by Geo. H. Mayhew for McFar- land Bros., of Denver, the contractors.
 The tramway is 234 miles in length. and commenced running on the 18th inst. without hitch. The contrac. tors,J. H. Thompson and Geo. P. Blair. viewed this operation with smiles. This line is what is known as the Bleichant tramway of Trenton, N. J. <.
 An engine of S5-horse power manages the tramway and runs the rock break CTS, which are located but a few feet from the mine. This line will supply the mill with 175 tons per day at an. average cost of l5 to 20 cents per ton. Formerly itcost $1.10 per ton to haul the ore by teams. Another inaportaas saving is made by the returning buck cts supplying the hoist with water, saving $l5 per day.
 The elevation of the mine above the mill is $50 feet. The altitude of the mill on the river is 2400 feet, and is on level with Tucson.
 Through the kindness of superin- tendent Geo. P. Blair, these facts are published. Andy J. Collins, one of the best mining men in the country, has had charge of the Mammoth mines al- most from the grass roots and is wsl versed in the Mammoth ground. Mr. Collins has enlarged the single shrdtof the Mammoth mine to e double eona partment to adepth of 600 feet. This shaft is perpendicular and is 100 feet east of the ore, body on the 500 foot level.
 The work on the Mammoth mine is as follows: r
 On the 100 foot level, the north ;diffei Is run on the ledge 800 feet and south 250 feet. rf
 On.the 200 foot level north on the ledge 800 feet and south 200 feet. 4
 On the 300 foot level the north drift runs 800 feet and south $50 feet. In the face of this sodth shaft the ore is 20 feet wide.
 On the 400 foot level the north drift runs $50 feet and 75 feet on the south. The south drift has IS feet of ore in the face.
 On the 800 foot level the vein was fol- lowed north 800 feet and to. the. south 200 feet.
 The 600 foot level entities the mine to it's name, for after drifting north s50 feet and connecting with winze from the 800 level, cross-cut was made last week, showing the ore body to be 52 feet wide. The south drift on the. 500 foot level is in 50 feet and is connec-. ted with a winze on the south drift of the 800 foot level. The ore body.in this mine increases as depth is at- tained.
 Very little stoping has been done from the 800 foot level down. This mine has produced about 2O0, 600 tons of ore. "a
 At the present depth of 800 feet the Mammoth has no moisture. The Col lins mine, belonging to the same camr pany, adjoins on the west, but has a parallel vein. This property has pres. duced several thousands tona of oza- Probably when the Mammoth mill sis enlarged the Collins will be worked from the Mammoth shaft. The south end of the Mammoth mine adjoins the Mohawk mine. The Mohawk psopss have worked up to the line, showing the face of the drift all in ore.
 The men employed at the Mammoth are: Wm. Armstrong, engineer at the hoist; Hon. Thos. E. Baker, engineer at the tramwsy; Walter James, car penter and timberman J. L. Knuda6ns blacksmith; William Lee, Grant Pool, Thos. Brown, J. Bouschet, Thos. Letcher, ". M. Murphy, miners; E. Ffl Armstrong, under car man, and T, Ei McCann, carman on top.
 It would be hard to find many mines like the Mammoth, that will proaacs 175 tons of ore per day with such ~ small force.
 But three men are required to cper. ate the tramway at the mine, and this includes the engineer. The ore is run the rock breaker and into the bins and goes to the mill, where one man does the dumping into the min bins.
 THE MOHAWK MINING COMPANY.
 This company is running 30 stamps i at the mine, getting it's water from the ! San Pedro.
 The workings of the Mohawk have reached 300 feet in depth. On tue 100 { foot level the north drift encounters ;he Mammoth line at distance of 500 l 'eet. The 2O0and 300 levels are run up 70 the Mammoth lines. In the face of
