Some Practical SlKjeestionS on I mP- of particular classes of the ore In
J a mine, have these assayed, and from
These Points. these results they estimate what grade of
ore they are mining. This may be cor
I rectly done, and it Is wonderful how close
1 to correct assays experienced men can
guess"; nut it is uncertain ai me nesi,
In former nrticlrs I laid especial stress
on the necessity o( sampling. I will Pre'" i

highest iiuthnrltv 1111 same.
"Accurate s.iinpliug isiiiilras essential
as .irrmatr assaying, for if the sample
dues not trulv represent the Int. ur mass,
from whKh it was taken, the subsequent
assiys will br valueless. I he assaver i
urclieniist will usually reieive the samples
alrn.nlv prepared, hut as he will occasion i

sample, a knowledge of the art ol samp

In the Notlhwrst the tnajoiitv of sun
pies brought to an assayer are lakrn bv
thr prospeitnr, or other hitrrrsird partv,
and as the assay renin. ales ,ire olten
used as dot-iiiiieularv evidence of the
value of the property, the assaver should

II an assaver samples tlie ore himself,
lie owes it to hiscllenl i 10 slat-, as il
doubles the value ol the cerllfuatr. If he
did not take I lit simple himsell he should
place the icspouslbililv ol Hie sample.
where it belongs, by stating who did lake
and dangerous for inexperienced persons
to attempt to be guided by such estimates.
Assays cannot be averaged, unless one
knows the actual weight ol the material
represented by each assay, and only then
by a long calci'lalinn, too long to be de
crlbed here, except briefly. In nine cases
out of ten when tlie "average assay of a
mine" is spoken of, it is incorrect and is
usually obtained by adding up a number
ol separate assays and dividing the sum
bv the number of such assays. It is
quite correct to ta':e an average sample,
have that assayed, and call It the average
assav; but this is seldom done. The cor
red average assay may be obtained by
multiplying the weight of each lots of the
oie bv the assay of such lot, add the,
products of such multiplitatiou and divide!
Ibis sum by the sum of the weights of the
various Ints of the ore. The quotient of
such division will be "the only correct
average assay" obtainable. O. M.

Portland' Prmarint Or Exhibit.
More than 750 mines of Oregon are now
leptesented in the. display of samples at
the permanent e liibtt of Oregon's re
sources, 246 Washington street. There
aie tour large cases of specimens, which
on 1 Include every district hi Oregon. Most of
the samples ate taken from working ore,
and show investors and those interested
in mines and mining actual values. That
the excellent collection is appreciated is
evidenced bv the number 01 people who
visit tlie place and examine the samples
daily. Mine owners themselves never 1
visit tlie city without "having a look
aiound." Every day new samples ol ore
are being received and placed in the per
maueiit exhibit. I'hey are labelled and
accredited to the proper district, mine and
owner. It is now the best mineral dis
play hi the Northwest, and serves as a
valuable object lesson in convincing
strangers ol Oregon's mineral resources.
Mote than one prospector and man of
means on his way to Alaska, after seeing
the display, has decided to cast his for
