George P. Blair, the new superlnten- dent of the Mammoth mine, starts thls property off with an assurance or suc- cess. The mine is one of the best in the territory and continued good man agement will make its owners rich, make the ranchers on the San Pedro happy and the business men of Tucson will welcome the trade that is forced that way, says the Tucson Citizen.
 The Mammoth mill started with fifty stamps last Tuesday after being over hauled by George H. Mayhew for Me Farland Bros of Denver, the con- tractors.
 The tramway is two and three quarter miles in length and com menced running on the 18th instant, without a hitch. The contractors, J. H. Thompson and George P. Blair, viewed this operation with smiles This line is what is known as the Bleichant tramway of Trenton, N. J. An engine of thirty-fve horse pow CT manages the tramway and runs the rock breakers 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 15 to 20 cents per ton. Formerly it cost s1.10 per ton to haul the ore by teams. Another inn portant saving is made by the return ing buckets supplying the hoist with water, saving s15 per day.
 The elevation of the mine above the mill is $50 feet. The altitude of the mill on the river, is 2,400 feet and is on a level with Tucson
 Through the kindness of superin- tendent George 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 all most from the grass roots and is well versed in the Mammoth ground. MT Collins has enlarged the single shaft of the Mammoth mine to a double compartment to depth of 500 feet This shaft is perpendicular and is 10C feet east of the ore body on the 600 foot level
 The work on the Mammoth mine is as follows: On the 100 foot level the north drift is run on the ledge 600 feet and south 250 feet
 On the 200 foot level north on the ledge 800 feet and south 200.
 
 duns 800 feet and south $50 feet In tht face of this south shaft the ore is 2( feet wide
 On the 400 foot level the north drif runs $50 feet and 75 on the south. Int south drift has IS feet of ore in tn, face
 On the 800 foot level the vein wa, followed north 800 feet and to tn south 200 feet.
 The 600 foot level entities the min to it's name, for after drifting nortl 250 feet and connecting with a wing from the 800 level, a crosscut wa made last week, showing the ore bod to be 52 feet wide. The south drift ol the 600 is in 50 feet and is connecte, with winZe on the south drift of tn 800. The ore body in this mine in creases as depth is attained
 Very little stoping has been don from the 300 foot level This min has produced 100000 tons of ore
 At the present depth of 600 feet tn Mammoth has no moisture. The Col lins mine. belonging to the same com pany, adjoins on the west but has parallel vein. This property has pro duced several thousand tons of ore Probably when the Mammoth mill i enlarged the Collins will be worke, from the Mammoth shaft. The soutl end Of the Mammoth mine adjoins tn Mohawk mine. The Mohawk peopl have worked up to the line, showin the face of the drift all in ore.
 But three men are required to oper ate the tramway at the mine, and thi includes the engineer. The ore is ru through the rock crusher and into tb bins and goes to the mill. where on man does the dumping into the mi bins.
