by the program.
To begin with, more than 10000 car
loads of material were used In their
construction, of which 1000 carloads
were of brick. Twenty million feet Of
lumber were used in the buildings and
100000 more in the seven miles Of
flume built to give the plant water
supply. Through this flume pour 5000
gallons OF water every minute into
the tanks, from which 1t goes to the
various part of the plant. Fifty thou
sand yards of masonry were construct
ed in the work and more than 100000
yards of earth we're excavated for
! foundations. One building, the con-
/ contractor, covers seven acres of ground.
! Those great bins at the reverberatory
/ building, that seem of medium size
in the big group, required the use of
! 100000 feet of lumber.
1.-THE water supply alone is an i'm
mense work, though small IN COMPARE
son with the other details. This queS-
ton of water supply is one which led
Marcus DAILY, back in 1882, TO decide
on locating the reduction works OF
conda. In the hills to the westward of
Anaconda is a watershed containing
an ineXhauStible supply in its chain
of lakes and multitude of streams. A
great territory in this watershed has
been acquired and a systematic plan
of storage reservoirs has been put into
effect Storm lake, far up in the hills,
has been damned so that the flood
water may not go to waste. Below 1t
is another and a larger body of water
Silver lake. Into Silver lake much
of the water of the region has been
diverted. Between this lake and the
valley of Warm Springs Is a low ridge
under which a tunnel is being driven
to flow the water into Warm Springs
creek and thence into the great flume
leading to the works. In the meantime
a pumping station has been established |
at the lake and the water Is pumped |
and piped over the ridge. Never can
of the works; never can 1t be appre-
ciably diminished.
"But the works themselves: The
structures which constitute the plant
proper are six in number, the con-
verter, concentration and bins, blast
furnace, reverberatory, powerhouse and
machine shops and rooster. In addt-
ton there Is an extensive bricquetting
plant, a handsome office building, an
assay office and laboratory OF large
Size and a number Of minor buildings.
Gas in all plants of this character,
the aim is to take the ore to the
higher level and then start it on its
progress into copper, each stage being
completed at a lower level so that
gravity may do the work Of removal
from department to department To
reach these higher levels, nine miles
of track were constructed, winding
about the side of the hill. On that
track monster engines haul the ore
trains that are brought from Butte.
The tracks reach every portion OF the !
plant, but in addition system Of in

Largest Engines In West
1.-THE Nordberg engines used In this
building powerhouse are
yigantic In size. exceeding anything
n the Rocky mountain region. There
IRE three of them, each having ca
,acity Of 5000 horsepower. One OF
worlds fair. The machinery Of the
plant Is the only one
which derives its power from these
engines. The machinery OF
ne other buildings derive their power
rom the powerhouse and machine
hop building.
