Ciuses of Mining Failures.

(Dr. Alex. Trippel, in Globe Silver BeIt)
 In recent issue of the Silver Belt you alluded to the result of a trial run made with the Comet ore as being sat lsfaciory. In so stating you have, doubtless, given persons unacquainted with the facts wrong impression, as the so-called test of Comet ore was far from satisfactory, not through the failure of the ore to meet expectations, but for the reason that the milling was nperfectly done, and the greater part of the silver left in the tailings. What was supposed to be an average sample of Comet tailings assayed 20 ounces in silver, and other samples still higher. The alleged mill test re- fleets unfavorably on the mine, but unjustly so, as the Comet is a valuable property, with successful future fl competently managed That the best mines can be ruined by incapable arrangements admits of no argument here. as we have far too many such evidences before our eyes in Globe dis trict which has been peculiarly unfor- tunate in having its best silver prop critics mismanaged, their value serious ly impaired, and the mines themselves rendered unproductiye, probably so long at least as they remain in the hands of their present owners
 1t is a well established fact that the principal copper mines in Globe dis trict have produced the best copper at less cost, than those of any other dis irict in Arizona, which Is the more re- markable when the remoteness ot Globe from railroad is considered The prospect seems favorable for the building of a north and south road through Globe at no distant date, and the cheaper transportation of fuel and bullion, which the advent of this rail road will effect, and the reduced "cost of supplies must greatly enchance the value of our copper mines. Notwith standing the success attained by the Old Dominion copper company in the production of copper, other eastern companies, owning mines as promis ing as the Globe mine, if not more so at the stage of development, have al lowed their property to remain idle and their smelling plants to decay.
 The case is much worse with ouI silver mines, a few of which are emi nently large mines and in the pas were heavy producers of silver and, i properly worked, would be to-day. 0 these the Stonewall Jackson is pre- eminent, the ledge being one of th' largest in the United States. A mum Der Uf our silver mines are owned b, parties residing at distance iron Globe, and the failure of their mining enterprises here are largely attribut able to their inexperience ill mining which has resulted in the selection 0 incompetent men to direct operations and the consequent ill-advised expen ditures. However, the mines and dis trict have had to bear the brunt c these inexcusable blunders, when il reality our silver mines are equally a promising as those Of other districts i Arizona of greater repute.
 What success has been achieved l silver mining in this district withi
 the past few years is due to individus effort and perseverance, and is cred
 to our miners. If nonresident min owners will employ capable superb tendents and work their mines intell gently, or else lease their claims, wit proper restrictions and on reasOnabl terms, Globe may be made one of tE most prosperous camps in Arizona.
