ore-house, will be broken by a rock.
breaker, which will be run by
small separate engine. After being
broken will be taken in cars to the
drying-room, which is ON the same
level, This drying-room is furnished
with Stedefeldt dryers, which are ser.
les of inclined shelves down which the
rock passes through heated chamber.
In this drying-room there are three
chambers, one for ore and two for salt.
The Stedefeldt plan Is new; one Of
the same style at Lexington Montana
is the only other Of the kind In the
United States. The ore dccends
twenty four feet, in passing through
the dryers and arrives at the Lowell of
the roll.room, from which when tt Ia
discharged II is taken to lopper
over BEodie erusher in The psll.
room, whence after being crushed II
passes through chute Into the

goes inlo the bin aud the remainder
Is discharged into chute which
takes 1t to the rolls ugai.l.
The pulp bin is on the same lcysI
with the roasting room and from tho
bin the pulp is taken In cars on n
track which extends over the rooster.
These roasters are revolving and ara
changed from four large hoppers.
After being roasted 1t passes through
u chute to the cooling floor IL feet

lower door of the large Teaching room
in which there are two platforms Ar.
lending along either side which each
contain twelvo yats eleven feet air
inches in diameter and four feet high.
a track Is suspended ovet' these yata
on Which cars run which carry and
discharge the ore. In the center ~
the teaching room is u high frame ON
which is placed two hyposulphite
tanks from which the solution can ha
drawn into any Of the vats, From tn.
ieaching vats the liquid is run into slr
preeipitalipg tanks on the floor Of thu
room, and when the metal has bean
precipitated, the solution is run jnto
Il large tank under the floor from
Which centrifugal pump carries IL
again to the tank un the frame. Bv
this operation the same solution /.
made to do duty many times and a
very great saving of expense 1.
effected, Messrs. Salkeld and Eckard
IN designing the works, provided
against waste in any direction and
have arranged to save all the fine dust
which is always valuable. From the
roasting room flue carries this dpst
to the long dust chamber where n
passes over and under many arches
until before the air in which It IA
suspended passes out towards the vent
stack 1t has all been deposited. The
teaching and boiler rooms extend tn
the front farther than the cooline room
and in the recess thus formed, a laree
tank will be placed where the solution
used in the process will be boiled.
D.. mo one can fully appreciate tho
extent OF the work and the KNOWLEDGE
ana care required in Its prosecution
without making visit to the place.
A great deal OF the material Is ON III.
ground and more is arriving daily.
