MINES AND MINING.

At home in Yayapai county, the mania for prospecting is, at present, far greater than the desire to work in the old mines, which mania Is, at this season of the year, quite natural.
 One oc the prospecting parties which left here last week, took along Mcssrs. Philip Richardson, Jake lluklc apl other old .taud-hys
 Then, Mcssrs. Vim Cole, l.. E. St. James and others have gone to whip around the prictta range, m hopes of striking something richer than any of Us have yet seen.
 Over On the Ilassayu placer miners have been, are yet, taking out great deal of gold, which Is sad ,o be worth more than Sl1 per ounce.
 The same may be said of Lynx creek and ifs miners, where, also, an ara.tra Is being operated by Mr. Pointer. upon ore from the Pointer lode.
 From the lla-sayampa, soine choice spcci mcnS were recently brought to town by Mr. \. Rolenburg, which specimens may bc secu at that gontlcman's place ot hu>iuc,s.
 Mcssrs C. W. Bowers. Hugo Richards, D. C. Morcanl and Geo. Hammond have rc- gently ,i-itcd a portion of the llas-tyampa, below W alnut Grove, with the ylew oi talk ing water upon some Oi the bars and working t1cm, but they failed to iiud enough water tO answer thelr purpu,e, and have, for the present, abandoned the ldca.
 Tho Mcs-ls. Jackson & ShOup are still running their mill and ara,tr,s in Bradshaw mountain, with good results.
 In Weaver district the Marcu, company are ara-trans, with good success
 Nc Smiths new mill, near Wickcnburg. is now naklng it's hr,t run on Nuiturc ore. The chance, are all in favor of success Tor its enterprising owner.
 The mnng news of Yuma county will be found ln our summary of news from Southern Arizona.
 That from the other Couniie, Is 20 meogrc, that we await further adyices.
 We, to-day, finish publishing the last of Professor EIier's report on the Territory and Us mineral resources, and hope that It will merit tbe attcntion of mlnins capitalists, whose aid our miners and prospectors so earnestly crave.
 His summing up k q candid statement of matters and things here, as IS the entire re- port.
 We have not much faith in new processes, yet give the following from late number of the San Francisco Bulletin:
 Since thc discovery of gold and silver bearing ores in the United states, many dc,icc, have been made by tc introduction oi processes to save the Itcciou, metals These experiment, have been attended with great amount Oi labor and heavy expense In many instances the result ha. proved fcmunerniiyc, but no prOccs, of working ores Yet adopted is sati-hciury, because of the large per. cruiaEc oi tliu metals lost Those interested in miuiDg operations have looked forward Co n time when 70 nc new and aiupe treatment of ores would be discovered which would say. more oi the metals with less expense than Inc methods now employed Eastern and foreign capitalists who arc interested iu mining operations complain | that atuough the orc assay Is large, the work Is not rciuuucrativc.
 lcu ycars ago merchant and scientific gentle. man Of New York City, commcnccd the cxami . nation Of this sniJcct by practical experiments which resulted in the discovery of a chenp and | simple process by which the reDvllious ores could | be made to yield up their gold and silver at a l much less cost than the usual method of W workiur md by the use of inexpensive materials save [ within a fraction of all metals in the ores The ,rcs are ground or puyetz.d, aud A chemical | ndnrn winch uesrroy's inc iinptTitics, ! ,rnd ,nd Che qhiekrii'pr readily gathers the metals h" ores arc takcb tn their Datur3iatite no ro1si. ng or burning Is required, and d short time only necessary Tor atnniguBlton.
