Bnt there Is another reason why the Silver ClIh

IN the manner in which it was set mp. Inc ma
chinery so Mr. Perkins SAYS is constantly breaking
or getting ont of order, so that the, mil whlch
ought to run a month without stopping. rarely goes

made of light galvanized iron, re not strong enough
TO stand the strain put upon them. Then the frames
of the battery are of iron instead Of wood, although
rs Mr.. Perkins says, iron batteries have been dis
carded for many years by Pacific Coast milling men,

Perkins has been gradually getting the mill INTO
better shape and one day since | came here sue
ceeded in crushing sixty tons of ore, the largest
amount believe ever run through IN twenty-f0ur
hours But the next day pipe burst and the mill
stood still several hours
think have now made it plain that the unsat-
isfactory results of the Silver Cliff mills run thus
far have not been due to the adoption OF a wrong
process for treating the ore, but to inexpeflence,
which was unavoidable in handling new ana
strange variety of rock and to defects in the mill
Hereafter m-men in Silver Cliff Will profit by the
knowledge OF the ore already acquired, ana In the
construction of mills the mistakes in this one
Will be avoided corrected, as some OF them have
already been corrected in the Plata Verde mill
now building. The Lew mill which the SILVER
Cliff Company intend to erect this coming autumn
will undoubtedly he model, and have no doubt
whatever OF Its success when completed.
1t Is impossible TO say how much per ton 1t VIII
cost TO mine and mill the chloride of Silver
Cliff when it is done with skill and experience,
proper machinery and appliances; but have no
hesitation in expressing the belief that it can be
done more cheaply than in any other silver mining
camp in this State. | have no doubt that within
year ore containing no more than ten ounces of sil,
yer TO a ton will be mined and treated here with
large profit The Silver Cliff mill averages 70
crush forty-hve to fifty tons Of ore day and lhayt
obtained, not from Mr. Perkins, but from another
source the items of expense involved IN disposing
of that amount Of ore. They are az follows:
