silver Mot ntasn.

This mountain b4came famou
 over eighteen years ago for it's larg'
 lndes that prospected ia gold and sii
 yer. It is safe to say there are ne
 such lodges containing either O
 these two metals in paying quhuti
 tics t. be found in any other place il ] the United States, unless l. be ir
 Idaho, and large lodes are made iC
 pay there that will not gay as mucl 1 in gold as these lodges as>ay in gold i while they assay full as much ol
 more in silver.
 i The location of Silver Mountain,
 the caracter of the country, rocks
 and formation anI nature of the ore
 veins are all favorable indications of l permanicity in the ore bodies and oi their value.
 i The mountain is Joe clted at the
 junction of the two principal belts
 nf lodes in Yavapai county, or we may say northern Arizona.
 One belt of lodes includes the 1 Tiger lode and mine. the Bradshaw , Basin mines, DclpascO, Warcagle and Peck; the other belt diverges to
 the east and includes the Grayeaglc, Orobonito, E lipse, Cougar, Lorens. Doyle, B ackwarrior, Silver Piince, 1 Copper Mountain and Black Hills
 copper mines.
 The formatia1 of Silver Mountain,
 like all the r,s, of Yavapai, is metal-
 ifeious, part of it is igneous and
 part is sedimentaIy. The igneous rocks are granite, porphries, ,dolerite, quartz. feldspar anl mineral veins
 All the igneous rock however, are in
 veins, dikes, or Lunches, having been
 ejecicd from beneath since the strat~
 ifie.i or scdim-nlary rocks Was form ed. The s,-dimentary rocks are
 syenite and slaie. mica, hornblend and chalk sla'es, mica, however, enters largely in'o lhe formation of the mounlain; there is some in the syenIte and most of the parphries.
 The ore veins are un ioubielly Of an igncous origin and generally very large. The principal lode is known as the Uni n, bul was first cal d the
 Mammoth. and is over ihree mil long, cx,en ling fioM the foothills C.. the nnrth 10 the foothills on the south side of Ihe mountain-the mountain is 1,501 feet high.
 The Mammoth is the most appro- pria'e name f3r he lode. for it is d mammoth vein in " dth and length. will measure in several pl .ces over 100 feet wide, and two of the claims the Union and Mountain King, will overrun 200 feet in width.
 The gangue of this vein is quartz ani feldsplr; it's base metals are sulphur, antimony anl arsenic the precious metals are gold an silver in nearly equal proportional value, there IS also some lp2er and on the south side of the mountain there is some lead.
 The gold and silver is very gener- ally distributed tbFou shout the
 lue. The gangue sh TVS some sirafihcations as the different mate rials coIlected together while cool ing, There have been no chan res in the caracter of the mountain since before the upheav the minertl veins are the latest formation. aad it is clear that they were formed be- fore the mountain was raised. The Mommoih Tod has all the brakes, slips, curves and lips, that can b. seen In all the other reefs and stra- ties at the summit of the m ,untiin
 The Mammoth lode is near the mid l'e of q streak of m;ca sha!e, about one mile wide and di.,s at an angle of 3jo shit.h IS also the angle i of the dip of the lode. There is one or two freaks il connection with the origin wit. the Hamm tn lode that | is cllcnllied to puzzle the brains of | geologists and miuerDlogiSfs. 1t | the north end of the Union mtpe the l ledge seems to have been broken of where it IS over 2 Q wide but sud denly reappetrs abour 300 yarls t1 the east and is over 200 feet " de on the surface for 7J) yard running for ! that length .iearly due elst, whe1 it | again assumes its general directi0n i abOat 5 de Irees northea-t ani cons | tinues on this line for about one nli,.; but the angular phenomenon in this portion of the lode is that it ! has d ike of IorpIyretic granit abont 40 yards wide Tn the middle | of the ore vsiR leaving about 20 tn | 30 feet wide or an ore veir on eli her l si,le of the dIIe. Nuw, how did thlS | like got in Inc mi lie of the ore vein or rather how did the ore vein get on eitaer sld of the dike. It is sad ny geolorist that there is nos thing in co c0lnection with the seJlo- gical formation of the earths crust that can't b. exDlained by establish ed philosophical and mech ,nical at least ihis can't. It IS self-eviient from the construction of | the Mammoth lode that 1t was once a elasm that exten led clean through | the crust Of ;he earth al Inc time il was fiilel; il was evidently formed ! hy some internal convulsion il part 1 at leasr, perhaps by an uphcavel of 1 the crust If the earth in the diree~ ! ton of the line of the lode by which the surFace was conveyed and thus to the width of ihe | chasm or lode. The crack in the | shell Of the earth would of course i follow the line of !he least resist ance, this was along the line of the 1 cfratf fGootiC, of tho g1,+o ,,-.:I 2.
