arrived here yssterday from Min ersl Creek. and must confess that the copper formation thero interests me more than any mining section have ever yet seen, and the only place 1 have eeen where the formation io SO clean and GetinIie that one unlettered iu the sciences ss myself can at once apply the geological and metallurgical theories and laws of the boOss, and for the first time have learned to pay proper respect to ths scieatihc book makers.
 There were shown me cast bodies of red oxides, where an inexperienced eye could detect nothing upon the surface but the mer.st stain or trace of copper, but the fade bleat he'd ,urface wac hn open book tO the wandering student of nature. At two O. three feet in depth color came, with four or five per cent. of copper, at five or ei1 feet, eight 10 tcB per cent, with unmIstakablo signs of better copper; at ten feet deep, eigh- teen tD twenly-tour per cent, aVerag- ing tweCty-twO per cent. from the pick without aasOrtlng. Tho pros pectOr here restc with a full EnOwl- edge Of great value. HIs premises are correct. for where in America is there \ copper mine that will chow d massive ore averaging O. much from the picks Thie same shaft st fifty feet will show an average of over thirty per cent Whys Because fully one-half of the body Of the ore ehOws that large per centage Of copper ha> passed away in solution. When sui ticienl de, tn is attained, the ore will be filled with fre-hnec, and. mark me, 1t will como to the front.
 As you intend 10 spend nJme time on Miners, Greek do not tail 10 exam inc with great care that large body O ore on the west side of the creek. If !s wonderful mass of copper. l sam pied 1t for more than lOO tcSt wide. It is different Tn character from the claSs above described. Here the prop 'sitiOn in the books that the of red oxides pr0duceo na- tive copper. is forcibly illustrated. nave even dared tO think that the practical les,"n Is sO plain and Con elusive tha. one might slrihe out and maintain propositions in advance If the authors. Why is not the ruby copper or vhitneyite found in this body of ore (sTsocisled with an en- closing native cOpper) only copper in n state tranEitinn from oxide tO purity, biding only timOs l. is sRly copper and water.
 We'll. to the point. think that cross -cut made here eight or teH feel ieep and one hundred feet wide, would ! show for one-hslf the gross tons eg- humed n average of moro than 20 | per cent. of fine copper. This is so concl Isive in my mind ss 10 admit Ul | DO doubt, and l have sonpled and 1 sssayed diligently, snd thrown every l doubt aGainst tho mine.
