 Tho Bismarck, immediately above the first spring ln Inc Oig canyon directly east of Union Pass, slightly opened and shows about l2 foot oi quartz, through which much galcua is scattered and 10 inghes of solid carbonate of lead and ane- grained gacna. IL runs east and west, like all the others. Location 1, 100 feet.
 The Aoieitamis q copper lode feet wide, about live miles north oT tue foregoing The ore Is very rich in copper, and carries much silver and little gold. A shaft 70 feet deep has been sunk on it formerly, but work has not yet been resumcd
 Tue Blue Bell, Darby, Dauicl Webster, and many others, are locations formerly made on some of which considerable work bas been done. They all contain gold and silver, but have not been re- opened as yet.
 The wallapai district is better situated, in re. gard 10 water and fuel, than most of the Colorado river districts, while as to transportation it far surpasscs the mining districts of middle Arizona Ore can be shipped to Cottonwood Island on the Colorado river, for from Slj 10 go per tou and from that point to San Francisco by watcr, for s2O This Is, Of course, still high freight, bui by smelling the ores into pig-lcad, which the silver will bc found concentrated, before shipping, min ing in this district can well bear it MiDers wages are from SG0 to s7j per month and board.
 The veins of the Wallapai district strike and d ip
 different from those of tbc Sierra Preta and have
 different character, a fact which deserves to be
 noted as probably referring them 10 a different age. The country rock here contains no olvine,
 which is abundant in Middle Arizona. l am in.

 are the oldest.
 San Francisco District The Black Mountains" described in former part of this chapter, have a small group of hills running out from tbcIn toward the southwest op.
 posite Hardyyille, on the Colorado river In these
 hills the san Francisco district is located. Several of tbe lodes discovered in it raised the widest excitement at the time of their discovery aud the "MOss lead" especially, contributed much to this when it became known that several hun. drcd pounds Of the croppngs sent to San Fran cisco had yielded at the rate of several thousand
 In gold per ton. Al present not single vein is worked here.

 work has been done here In tunnels and shafts

Many cross-cuts in the Porpbyry are also made from the tunuel partly running parallel 10 the vein and partly at rigIt angles 10 it, but none reach it One shaft Is .nnk In the loot wall Of the vein from the surface and has, or course never struck it; while another one Tn the hanging wall, has, before mentioned reached it at a depth Of 80 feet Whoever manned these works must have evidently seen drawlngs l of mining works in depth, without understanding their import.
 Aportion of the outcrop has been quarried and | worked Tn the mill of the company at Hardyville on the Colorado, nine miles oil. The returns were not satisfactory. The gold though abundant and | snowy ID spots, seems 10 have been badly distrib- uted The assay record at the mill, at lcast indi- cates this. The quartz is dense, slightly iron stained, aDd looks more like metainorphos.d sandstone than like gold quartz. It coutaIus. al lhe cropping, patches of heavy spar and felspar Nevertheless, IL cannot be said that the work ng oi the vein has proved against its value for Inc vein, beyond a single spot at the cranuinos has never been worked.
 An excellent stone boardlng-house was erected near the ihine by the company; also, the neces- 'ary blacksmith shops dSc.
 The road from the mine to the mill leads down ! broad arroyo, with very sandy bottom through.

The mill has ten stamps, four pans, { Wo wooden and one small iron settler and is run 1 y dO-horse power engine, which also pumps the , Vater up into tank above the mill from th. Col | 'rado river.

 The Southern Cross Is a vein upon which more | Fork has been done than upon all the others in he district together. About S700OO has been ex | 'ended In tunneling and sbaiting, all Of which is 'eIl'phnned and executed, but it establishes be- ohd a douot that tue Southern Cross will never I uPport prosperous enterprise.
