From El Dorado County, BY OUR THAVELING CORRKSPONDENT, [Continued from Page 267.) One mile southerly, from the Red Hill claim, lying along the bed of Duteh Creek, and two miles southwest of Kelsey, is TRE PLYMOUTH CLAIM, Which we lave deemed advisable to notice in this eonneetion (although last visited), in yiew of the sulphurets and arseniated sulphurets of iron alluded to before, but here found in the greatest abundanee,. and in every imawinable variety. All sizes, shapes, shades and states are represented, from the little irrezular sulphuret of different mineral bases —dark, gray, or yellow, and of almost every hue—living, lifeless, decayed—so small as only to be seen with a glass of considerable magnilying power, to a large wedge-shaped mineral eompound, eontaining certain proportions of iron, sulphur and arseuie, if not other minerals; a hard, dark-brown substance, somewhat fnsible and of such magnitude as in some instanees, perhaps, to weigh fully fifteen ponnds, one piece being eighteen inches wide, four feet long and one foot thick, Some of it having been brought to a red heat under the blow-pipe, showed, in cooling, o surface dotted over with delieate little specks of gold, less brilliaut than the native specimens to be seen in the quartz; hut seareely less beautiful and attractive to the eye of the cprious, ‘This species is always found here firmly attached to a tough black slate, somewhat glazed and crisped, apparently its natural casing, whether found as the wall of the lode, or as strata cutting the quartz. The company have spnk a shaft to the depth of fifty feet on the lode, which is from twelve to fourteen feet wide, and have abont 1,000 tons of rock ready for crushing, estimated by Mr. Potter, the Superintendent, to nverage from $20 to $25 per ton. They have a small 2-stamp niill, pump, arastra, and eoncentrator— the stamps not weighing over sixty pounds each—and all are run by tweuty inches of water, the diameter of the wheel being about twenty feet. ‘The sulphuret separator or coneentrator is an invention of Mr, M. M.A. Woodside, of Georgetown, cheap, simple and effective, and as he has wade application for a patent, we shall not under‘ake « description of it; 2,500 pounds of the. arsanite, worked in San Francisco, returned at the rate of ahout $150 per ton. Messrs. Potter & Hunsneker, at the mine, tested 150 pounds of itaftcra method of their own, and assured me that they obtained one dollar per pound, getting a much larger yield from some of the sulphurets, whieh ran, in some instances, as high as five dollars per pound. ‘he affairs of the company are in a very good condition as regards their finances, the whole of the work done, and the improvemeuts made at the mine, having been paid for by the product of the same, while they have some money in the treasury. All they need is a good engine and mill, guided by the samo prudence and eeonomy heretofore manifested in their operations, to make this one of the foremost mines of the county, if we can judge anythiny from its past history and present indicatious. ‘ About midway between the Plymouth mine and Kelsey, on the range of the great mineral belt, supposed by many to extend with a width of some ten miles along the western slope of the Sierras the whole length of the State,a large ledge may be seen from a distance of miles around, crossing the country from north ‘to south, and eropping boldly out on hillside or mountain top, displaying here and there very larve masses of quartz boulders—with heap on heap—remiuding one of Vulcan and <his once burning forge, ur of some powerful interual eruptive force, adequate to prodace the effeets here visible in the form of the vast blows or chimneys so often brought to view. Near one of these is situated the claim of THE GOPAER MININO COMPANY. Und r the guidance of Mr. Higzins, the Superinteudent of the works, I passed slong the ‘main tunnel, well and substantially timbered the distar.ce of 256 feet; and through cross-cuts and drifts, pnotil I had traversed a’ distunce in the aggregate of 500 feet, mosily through quartz, whieh is thought to be worth from eight to twelve dollars per ton, some thirly tuus having worked the latter amount
