tiations which have passed between the owners of the properties. It is stated on good authority that the con- solidation of these mines will possibly include the Keystone and Live Oak mines. which are m the same district, and for which the question of ade- quate milling facilities must soon be considered.
 Miami IS going proposition. Its splendid new mill is treating in three units l.500 tons of ore daily and the S2 per cent recovery of the copper metal in the ores now being had eclipses even the meritorious achieve ments of the Utah Copper and Nevada Consolidated mills by a considerable margin.
 All earlier estimates of Miami's en- gineers as to recovery and costs are being bettered in actual operation. so that it would seem safe to predict for the company an ultimate copper cost of not exceeding 715 cents per pound. with 7-cent cost among the reason able possibilities. The companV's of ficials. however, while gratified at the showing of the mill to date. are not willing to put themselves on record as to what the company's ultimate cost will be.
 Inspiration has vet announced no final plans with respect to milling fa- cilities and it is fair to conjecture that the delay in such announcement has been due to the possibilities of some sort of merger of the southwest ern porphyries.
 While MiamfS demonstrated ore re- serve is only about 1S,0O0 900 or 2O.- OOO,000 tons, this represents but very small portion of the company's mineraliZed area of 222 acres, and there should be two or three tirias this tonnage of ore within the con pany's mineralized domain Inspira- ton has demonstrated to date 25.0OO.- GOO tons. and it's engineers state rosi- lively that it may be considered a 5O.- O00,000-ton proposition
 A consolidated proprrtv with IO0.- 100000 tons of ore reserves and one huge mill would seen to be uaite n line with the logic aud economies of the situation. The salient details of each property gre as follows:

 Hope that Tombstone will within ihe very near future resume it's old role as one of the foremost producing camps of the southwest vas recently expressed by a Douglas currespon- Gcnt. who said:
 Ever since the rehabilitation of Tombstone in the latter sos by r B. Gage and associates the opinion of eminent mining engineers and otrer noted authorities has been such that great ore deposits exist below the water level and that with the pr, Ter development of all the properties large bodies of ore would be uncovered which during the past years have been hidden in the bosom of old Mother Earth.
 For the past nine years, and until the recent shutdown of the Tombstone Consolidated Mines company. the un watering of the lower level of tea old workings was the main item of Cx- pense, averaging about S5. 900 Der day while the pumping record was on an average every tWenty-fou- hours be- tween four to seven million gallons.
 The most costly pumping plant and battery of boilers ever installed in the southwest have been put into place at Tombstone at the cost of many hundreds oi thousands of dollars. be- sides the erection of a s75.O0G air corn. pressor, the largest in Arizona
 The ore shipemnts being made from Tombstone to the smelte:S at Douglas and Fl Paso are incrpasi,,a daily, the chloriders, besides other companies operating in the district. shipping on the average of two and three cars daily
 From what can be ascarrained at this writing, it is understood that il IS the intention of the Tombst, ne Con solidated Mines company to take nm all obligations now existing against if and pay off the same, and dismiss ail suits now pending in the district court Should this prove to be the case. 1t will be but matter of a short time when the large pumping plant will again be in operation. and the mammoth stamp mill and concen- tratinS plant again putting upon the market of the world it's share of the precious metals"
 Tributary to the Tombstone are the Dragoon and Huachuca mining dis tricts, both of which are coming rap- idly into the front ranks of the pro- ducing sections
