These three mines were operated
continuously throughout the year and
shipped $1,000 tons of clean crude ore
and high grade concentrates in lead
silver and zinc mineral, and fully 80
per cent Of this great output came
from development work, which is a
very satisfactory showing from for
nation that for years held such a poor
place in the opinion of the experts OF
national and local repute, and | am

New Power Line.
One of the interesting new features
OF the years progress in this and in
the Occur d'Alene district was the
construction of a power line extend
ing from the Morning mine at Mullan
across the mountains to Burke and
then to the Montana line, where 1t Is
connected with a line built from the
Thompson Falls Power plant Of the
Montana Power company on Clarks
Fork of the Columbia, which passes a
point Of convenient access with shorl
branches to the Nine Mile properties
and it is believed will afford a source
Of electric power at much more reaS-
enable rates than was before available
which will greatly facilitate the open
ing up and development Of these new
enterprises. This new power line con-
struction is of a most substantial
character and built with a view to
hard and heavy service.
MuIlan Mines.
The Mulan district suffered rather
dull year by reason of the closing down
of the National, Snowstorm and the
Morning mines which afford its prin-
cipal source of business, and Were
forced to suspend operations in the
summer owing to the lack Of demand
for their ores by the shelters. \
large force was kept on, however, by
the company at the Morning as long
as possible, and the big vertical four
compartment shaft extending down
1850 feet from the No. 6, two-mile tun-
bottom and the milling plant greatly
enlarged at the fine end, where com
plete flotation and other slime concen-
tration machinery was installed, witt
a daily capacity of 500 tons, that is the
result Of series of years of close
study and development along this line
by the Federal company and viii

this big mill when operations are re.
sumed.
In the Snowstorm mine, above Null
Ian, the STOPPING ore resources Of its bis
mineral channel were exhausted about
September and the milling operations
This handsome channel of
clean copper ore, with a production
record exceeding ten million dollars in
vlaue, was cut off by fault at the No
tunnel level and the commercial ore
above this fault has been entirely
cleaned up and exhausted. The com.
