sailing 81 tons of ore, from nine ounces
| to 251 ounces, which he was selling TO the
st. Louis Smelling and Refining Company.
| G. Fl. Larke, the manager, caught Pope in
the act. The company would have lost $225,-
| 000 had it gone through. Some fine detec-
tive work on the part of the employees pre-
vented it. t had been discovered that Pope
swindled Cummings s Finn, smeltermen,
out of $18, ,0OO last September. He has been
making boasts that he would leave town in q
fews days with $4,000 He has ''salted'
| low grade ores with fine chlorides after they
have been prepared for assay, going to the
smelter for that purpose.
MIR. BRADY's REPORT ON BARKER.
We have been permitted to makea few ex-
tracts from the report Of Prof. Brady, who,
| il will be remembered, was sent as an expert
to inspect the Barker Mining district.
Nr. Brady took samples from about sixty
mines and makes his own assays. He neith-
ec allowed any one to select the samples for
him or make assays, prefe7ring to do it all
himself.
The camp as whole he says is the most
promising one in America These are his
words. The mines are accessible without
difficulty, and are easily worked. The ore
IS a rule he believes is susceptible Of being
easily reduced. He deprecates the fact that
so little~~work has been done on the mines
and 80 injudiciously what has been done,
and thinks another year will see more valua-
BILE discoveries made in the district.
The most satisfactory assays were made
from ores taken from the Belt Park District
an encouraging statement for the gentle
men who have located leads in that District.
OF the Belt Park mines he mentions the
Homestake, Queen Of the Hills, Hillsdale,
Whale end others that assay way up il the
hundreds.
The Wright 8 Edwards, Barker, Benton,
Uncle Mike, Ripan, Cleveland, Montana
Chief and several others in the Barker Dis
trict receive special mention.
Mr. Brady thinks more development must
be made to induce capital to invest and urges
the necessity Of doing more work and less
prospecting. His report is very fair re-
view of the camp and will doubtless lead to
the coming Of capital and another smelter.
THE PULyERIzFR.
The Butte llSner Of last week devotes con-
siderable space to the ''PulYerizer, q new
apparatus for crushing ore which has been
tested at the Silver City. The Miner
pronouuces it a great success and thinks it is
destined to supercede to large extent the
method Of treating ore now in vogue, The
following will give some idea of the work
accomplished by the pulverizer:
The GRE was carted in from the dump, hard
and soft all alike, was fed through the rock
breaker into the mill, and was completely
end successfully pulYerized, without and
picking or roasting, SO that it easily passes
through forty mesh screen, and thence to
the amagamating tubs. The capacity OF the
mill as demonstrated during the time It was
run was 90 tons ia Il hours, or in other
words, the equivalent of twenty stamp, at
one-thlrd Of the cost CT the ia tchinery and
with one-third the 9A ~ 3: = t'I"! and IaDor.
The operation is surprisingly simple and IS
easily understood The ore is taken fresh
from the mine, and one man feeds it to the
Challenge Crusher, through which il passes
to the mill, which is worked by ten horse
power engine, anl pulverizes the crushed ore
simply by skilIful application OF centrifugal
force Twelve cast iron rolls move freely
side by side around the exterior OF the Muller
Plate, grinding the ore to powder as it is
hurled between them by the centrifugal
force. The machine Tevolvos rapidly, max
ing from 175 to 200 revolutions per minute,
uasng barrel Of Wa6er-which is forced up
from beneath the muller plate end fslla over
the rolls from above-and passing the pow
dersd ore through screens, 40 or 50 N esh as
deairable-along with the current Of water.
So FAR only the lgbor Of oIe man ls 4 neeaed,
and when il IS considered hy 6 very simple
process ths same ustac which conducts the
pu1vsrized ora into the astting vats Is then
raconductea thraugh the nlilh itg complete
nasa is wondsrful. Thence forward tho pro-
cess norv uses1 aS the Magna Cherta is the
ordinary Cry crushing process: Tbs simple
ity and perfection Of Nr. HoWland's method
Is illustrated 81 tho fact shat, although the
mill uHas barrsl OF Wstsr minute, sixty
barrels suffice for its continuous operation,
"a By an ingenious system OF cups revolving
over q wheel the Same water ID conducted
9zona The settling vets back inte the tank
from which it is fed to the mill. The same
fniehed severity or detail characterizes the
entire process But only a practical test and
personal examination Will enable one to real
iza the great results obtained with so much
ease.
