'Editors Herald: I have heard it sut'ircsted by croak-i croak-i era and hureliuatL) that the Luuua was the only reaily valuable mine iu the district; but there are other mines ot Kreat value here, some of which promise prom-ise fairly to rival tho Emma uul a j mere fpteulative, suii'acc promise, but ! a promUe based upon developments extensive enough to enable one to form jan opinion from actual observation ! down in the depths uf the earth, instead in-stead of u.-icj ahove ground the com-mon com-mon divining rods, personal whims and 1 pet geological theories. Among those ' mines, and equalling, if not surpassing, ,the Eujuia in the riehne.-ss of it ores, U THE SAVAGE, Which is situated due north from the j north end of the Emma tunnel. This I mine was di.-covered in cutting a trail i to the Gophir mine a proof that luck is a fortune and presented, when struck, only a narrow seam of rich ore. An irregular shaft following the dip has been sunk lo a depth of feet. The vein proved to be continuous, although al-though dipping irregularly, soon widened widen-ed to about 'd feet, and hearing ore of a richer average than perhaps any mine yet opened in the Territory. The wall rock is well defined, and the lode has all the characteristics of a figure vein. The owners of the mine are running run-ning a direet incline from the lowest elbow in the dip of the lode, to the surface, which will greatly facilitate tho hoisting of the ores and debris. At a little less altitude than the Savage, and about 1,5(JU feet from it in a westerly west-erly direction, is j THE .1IOXTEZUM.V, Opened by an incline iJUU feet in length, (following a large lode of ore the entire i distance. Work is being prosecuted at the bottom cud oi' this incline, and ! tho width of the lode has developed I into dimensions larger than the sine of tho incline. An immense quantity of ore is in sight, largely exceeding tho quantity exhibited by the Savage, hut not so rich in quality. - Crossing over the divide to the Rig Cottonwood side, near the summit, we come to TIIE READ AND BENSON MINE, ' The ore vein of which runs transversely with the country rock formation, a condition asserted by geologists to bo: invariable wiih truo fissures. This mine is opened by an incline of about fifty feet in length, aud shows an immense im-mense quantity of good ores, principally princip-ally carbonates, but carrying some galena ga-lena and chlorides.. At the bottom of the incline the lode is 7j feet wide, but at some places it has widened to lli or 13 feet. A large quantity of ore is on the dump awaiting shipment. Tho walls of the mine are irregular, zig-zagcy, zig-zagcy, but this remark only applies to the lace of them; their general direction direc-tion is very uniform, and this, more than a smooth face, is indicative of a lasting deposit. It seems to be characteristic charac-teristic of most of the lodes of this district, thai they aro richer in proportion propor-tion as the inclosing rock shows meta-uiorphic meta-uiorphic action. How this came to be so is a question of quien sabe't I have referred to thopo mines in particul.u' because they, in connection with a few others, arc sufficiently developed de-veloped to give assurance of permanency. perma-nency. I doubt if even the most stubborn stub-born stickler for a special theory as to the necessity for a country formation different from that existing here, or an expert who goes into rabies at the sight of limestone, would refuse to acknowledge ac-knowledge alter an examination of these mines that the durability of ore deposits or veins is not subject to tho kind of rock that incloses them. Experience Ex-perience provos that silver ores are found in particular sections of couutry, in mountain ranges the general formations forma-tions of which aro different. The general theory as to the formation of ore lodes or veins is that by igneous agency or in a state of ebullition the metal forced fissures in the superincumbent superin-cumbent rocks or filled fissures already formed by some natural convulsion; and oertaioly, if this theory is correct, the extent of doposits or veins is not controlled by the particular character" of the general rock formation of the country.
