FLATTERING REPORT.

Bulletin No 100 issued by the State
College OF Washington gives the re-
suit Of an investigation by F. ". Han
dy. assistant professor Of geology.
Professor Handy has the happy fac
ulty OF expressing himself in language
that the average layman can under
stand instead of shooting over their
heads in technical terms and using
words of many syllables.
The writer OF this article was in the
field with Mr.. Handy last season for
about FIVE weeks and found while he
is a man of few words, the little he
did say was eminently practical and 10
the point; no opinions were expressed
off hand
Northern Okanogan county has for
the past % years been endeayoring TO
make mines out of the small rich
streakS OF ore that exist here and
failed Professor Handy at once rec
ognized the fact that these small
shoots were only a minute part of
large. low grade ore bodies: this fact
had always been overlooked by the
prospector as we'll as by the many So
called mining engineers who have Wis
tied this district
Professor Handy divides the forms
OF occurrence OF economic minerals
IL this district into four classes, viz;
I'D true assure veins; (2l gold quartz
lIdes; (Sl gold and copper replacement
lodes. and CA determinations. The
two latter are doubtless the ones to
which we may look for our big mines
which can only be successfully ham
died by large capital. These cover 4
very large area and the work of de-
termining the commercial portions by
sampling and mapping them out must
b the work OF exploration companies
with moderate capital to make them
attractive TO the large investor.
The bulletin states where similar
deposits exist. viz: gold quartz lodes
in crumpled schists" the nearest and
best known being tie lodes OF Porcu-
pine. Ontario. the Australian lodes in
schists. the Halle mine in the Appa-
lachian and the Homestake lode in
South Dakota. All rated among the
ulS SOlO HINES u A-S " oG4N
Since this bulletin was compiled.
the largest operations in the Juneau
states Of Alaska have been made pub
lie. These operations are being car
ried on BY the Hayden. Stone-Jacklin
syndicate and another adjoining by
Fred. W. Bradley, who is me manager
OF the Treadwell mine and president OF
the Bunker Hill & Sullivan in the
Occur dAlenes. The former syndicate
is milling 5000 tons of states with a
total recovery of 1925 and net profit
% IS cents per ton.
The bulletin also gives much atten-
ton TO the replacement lodes," and
indicates that they promise opportuni-
ties for big operations in mining and
that naturalization gives every evil
dence of persisting TO great depths. "
This was written before the Ivanhoe
mine had reached their ore body at l
depth OF 1000 feet
Under the head OF prospecting AMI
exploration the bulletin says:
There is still much work for the
prospector Not over five per cent Of
the area of the iron caps" has been
actually tested. The gold dissemina
tons and the gold quartz lodes in
sehists have not even been recognized.
The latter may be recognized by the
pitted quartz float and the graphite
bands In the iron caps" deeply oxi-
diced bands. arsenophyrite, chalco-
pyrite and garnet rock are good ind;-
cations Any rock, granite or schist-
ose, with abundant sulphides or rusty
spots. may carry large. workable areas
OF disseminated ores"
