170 THE WEST SHORE. QUARTZ MINES OF WESTERN OREGON. riAIIE quartz mining industry of Southern and Wes I tern Oregon, although a matter of twenty-five A years standing, has of late begun to nttnin a pmm iuenoo which stamps it an almost a now industry. At various time within that period discoveries of great er or lees importance have brought the aubjoet promi nently before tho people, but tho intorewt thus awakened invariably proved ephemeral, and in no caso hiui the community at large reoeivod permanent benefit from such discoveries, and tho individualH who have lxmoGt by them have been few. Tho stagnation and depression prevailing in other line of buHineaa has of late caused the diversion of con siderable wealth into mining pursuit, and to a largo ex tant those principle which prevail in ordinary buaiueas have boon transplanted into the new pursuit of gold and ailver mining, thereby placing it on a plane of rosponsi bility and straightforwardness. Men who deairo to fo vea! in minus now demand to kuow plainly tho chances of loaa or gain, and tho facta ombraood in thia articlo were gathered with tho view of disseminating such in formation aa may servo to tomtit inveators and prospoc tora in a olmioo of location in which to conduct tlioir oMiraliona. Without further preface, wo will proceod to ooiiaidor tho difTereut quartz mining districts of the slate. Thero is no doubt but that motamorphio voin-bear-ing rocks of tho same description aa thoao which pre vail in tho mineral regious of California, oxiat in great thickneaa on tho wontcm aloe of tho Cascades; but un fortunately denudation by glaciers and mountain streams has failed to remove tho lava, sandstone and other late formations which lio upon and conceal them and their mineral wealth. It is only about tho headwaters of such Ktwerful streams as tho Umpqua, tho McKon.ie, tho Hautiam and tho Molalla that the erosion haa gone deep enough to cxpoae miueral voius of magnitudo. On the former stream some promising quarts leads are now being prospect!; ou the Sautiain several mines have at times been worked, and indications are very favorable for Uie finding of additional extensive and rich veins in tho lower exposed strata all along the western sIojms of tho range. It is almost unnecessary to add that the alluvium of nearly all the mountain streams flowing from this region contains gold, sometimes constituting workable placers. The principal mines of Southern Oregon are not situated in the Cascade range, but in the transverse chains which connect that range with the ooaat mountains. The formations are like those of Northern California, the same description of slnUs pre dominating, and quarli veins are largo and numerous. The uuwt important lodes lio in Uie hills which separato Uie Rogue, Applegate, Illinois and South Umpqua rivers. JACKSOH CltEEE DISTRICT. The Jackson creek quarts veins belong to a strongly develojwd system which eriueates the attfep hilla which lie about tho headwaters of that stream, and are charac terized by parallelism and uniformity of dip. They con tain little base metal, and their content of gold ia found in small, but often very rioh chutes in short, they are " pocket " vnins. The principal mines thus far worked are the Hicks ledge, the first quartz vein worked in Ore gon; the Davenport, Bowden, Holman, Johnson and El der and New El Dorndo, all of which have produced con siderable gold, thoir estimated production being as fol lows: Davenport lodge 110,000.00 Holman " 10,000.00 Hicks " 2,000.00 Bowden " 5,000.00 Johnson and Elder New El Dorado. Since the rovival of quartz mining in Jackson county, work has been resumed on the Davenport, Bowden and New El Dorado claims, with great promise of sucoess. Besides thoso, sovoral hundred new locations have been made, fiuo prospects being found in innumerable places. The most noted of the now minos are the Bell & Moody, Birdseye & Co., and the Mosquito guloh claim. This district has the advantage of possessing a good quartz mill, with efliciont apparatus for working large or small lota of ore. The Salmon pulverizer, the best quartz re ducing machine yet invented, is in use at this mill, und givos tho best of satisfaction to' those able to judge of its workings. A1TLKOATE DISTRICT. This diHtrict includes but one mine that has yet pro duced gold, but that one is the renowned "Steamboat" mine the moat prwluctive claim ever worked in Ore gon. It was discovered in 18(50, and within two years produced $.'115,000 almost as much as all the other quartz minos in Southorn and Western Oregon. Sev eral partners owned it, but abandoning the claim after it was in their opinion thoroughly worked out, it lay foi many years idle, but eventually fell into the hands of Richard Cook, who is now engaged in prospecting for further deposits. OOLD HILL DISTRICT. Qold Hill, a noted landmark in the Rogue river val- . ley, has a wonderful history, the most of which is due to the finding of the celebrated quartz mine in I860, which has ever since been known by the name of the Gold Hill mine. It was an immense "pocket" of very rich quarts nuggeU, which gave out after a few weeks' work, but in that short space produced $150,000. The rock was worked at first by arastra, but during the year of its discovery a steam mill of twelve stamps, the first built in Oregon, was brought from San Francisco and set up at the Dardanelles, the present crossing place of the railroad bridge over the Rogue river. Nothing of mo ment has been done on the mine since 1861, but the or ganization which owns it is still kept up. In Uie neighborhood of Qold Hill are several other important claims, tho Blackwell, Swiuden, McDonough,
