HARsHAw, July 15.-The practical success of the first great mine n camp is always an event of almost vital importance to lhe prOspectOTS and residents of the district generally. Haishaw is no exception. And thls is why the people of this camp feel a more than ordinary pIide in the HeImosa While here, as elsewhere, q small remnant of the original body of croakers may be encountered, they are fast dying out under the influence of the sunshine Of certainty which is breaking over the future of the camp, and & the day approaches when the formidable looking HermOsa mill will commence tO reduce the huge quanti- ly Uf rich ore Tn sight, the little camp ot the grOwlers IS almost thined out in favor of the told you sO's."
 My visit to the HermOsa mine, which is situated something over a mile from the town, was rendered dOubly pleasant Ey the courtesies which were shown me from Superintendent Gillette down to the miners in the works. Mr. Lar " Connolly, the foreman, kindly con- ducled me through the working, and enabled me 10 get very clear idea Of the lay " of the property. Although still a young man, he has so improved his opportunities as to acquire vast deal u information regarding praCti- cal mining, and enjoys a most envIa- ble reputation.
 The history of the location of the Hermosa and of its purchase and the organization of the company by MI Gillette is too well known to need rep ejition. The two main parallel ledges traverse the hill. and are cut by a tun- nel at a vertical depth of 250 feet from the summit, or 460 feet on the incline. This tunnel is as yet the deepest working, and was but recently finish ed. There ale altogether m the mine If openings, which, when measured on last Saturday night, showed total length of 3002 feet. The face of each of the entire number of openings Is In ore. The two veins at nearly all points of the present development show a width of 12 feet, with most remarkable uniformity, and the quartz AAC AObl hkAho nnNANfEl NA HO0NA AAE clearly marked. From a nun Der of the shafts not pound If waste has been extracted. From the start the quality of the Ore-which Is tree-mill- ing chlorides and horn silver-ha- been carefully determined Dy assays and averages, and the most striking cir cumstance Tn connection with the property is the uniform results obtain ed. An examination of the assay books shows column afler column of figures with but the slightest differ cnce, and the estimate based on the numerous averages places the value of the ore throughout the entire mine at $l00 per ton.
 The next feature of the mine which attracts immediate attention is the ad- mirable manner in which 1t has been opened, and the judgment displayed m the arrangements for extracting lbe ores. The only hoisting that Is nee cssary Is in the sinking of the shafts. When connection is once made with the lower workings, all hoisting ceases, and by means of a series of chutcs and tracks, the only time the ore has to be handled is when it is first taken from the ledge. At the northerly end of the tunnel will be the waste dump. At the sOu'heriy end there is a large ore bin, in which the cars discharge their loads, and the ore wagons in the gulch below are loaded by means of a slide al the bottom of the bin. Down the sulch 10 the top of the hill at the rear O. the batteries the road has been graded hke q boulevard.
 The mill itself does not differ essen tially from later structures of the same character, though a number of i'm provemeujs with q view to obtaining automatic results in handling the ore have been added; but in thOroughness Of work and substantial character, ] am told by disin,erested parties, that II IS approached by few, if any mills, on the coast. l. leeks as If it had come to stay. The machinery was built by Prescott, Scott & Co, of San Fran cisco, and at present has two batteries of ten stamps each. The building. most substantial looking structure, is so arranged that an additional 20 stamps may be added at any time. The work of it's erection has been un- der the charge of MT. J. B. White. and the result adds laurel to his already me reputation. MT. <. Hoover will nave charge of the mill af CT it's con- ple;icn. It is now intended to com. mence milling the ore on the 2Oth in- etant, aed the estimated capaCitv of
