that point where Snow creek empires
into Carpenter creek.
Much Of this road was accordingly
rebuilt. some of the steep grades were
eliminated and in some parts OF the
valley entirely new roads were con-
structed. A good road was also built
running up the hill to the tunnel on
the Silver Dyke property, in all about
four miles of road being constructed.
In this road construction four instltu-
! tons contributed, the mining company,
the mill contractor, the Montana Power
company and the county Of Cascade.
One of the first tasks to be I'M
dertaken by the mining company was
the construction of a tramway from
the foot of the hill to the upper end
of the mill site OF the top of the hill,
which is between GOO and TOO feet
above the valley. This tramway is
1900 feet in length with a maximum
grade of - per cent and an average
grade of % per cent. Over this. tram
cables. the hoist being rated Mt 90
horse power for which the power is
furnished by a 70 horse power steam
plant. The latter is a temporary pow
er plant and is about to be replaced
by an electric hoist with Il capacity Of
about 30 horse power.
This tram is at present utilized only
for the lifting of building materials
and machinery for the mill and sup
plies for the mine but it will later be
a permanent feature of the mine and
mill and will be enclosed from top to
bottom by a snow shed.
Mill Operated by Electricity
The mill. the upper section Of which
is on a level with the mine opening
about a quarter of a mile distant, will
be a very large timber structure ex-
tending for quite q distance down the
Mill. All of the concrete foundations
for this mill have been completed and
the concrete floors are now being
sections have been finished and the
millwrights are gradually working up
toward the top section.
1t will be operated by electricity
and will have a capacity of treating
1900 ons of ore every "a hours. 1t
is the expectation of the supcrintend-
ent of construction. Harvey Mathews
Of Denver. that the mill will be com
pleted about January IS.
Water, of which large quantities
will be required for the operation Of
this mill. will be taken from Carpenter
creek and will be lifted about 200 feet
through 4 main starting at & inches at
the bottom and reducing TO four inches
at the top. This will be elevated by
4 pump having a capacity OF 200 gal
Ions a minute. The steam boiler at
present used in the temporary hoist
will be moved to the bottom of the
hill and will be utilized in producing

the mill. q four-inch steam pipe being
laid in the same trench that will car
ry the water main up the hill. A fiji
ter plant will also be installed at the
creek.
An immense amount Of modern ma
chinery. all of which will be operated
by electricity. will be installed in the
mill, this machinery coming from many
parts of thes United States. A good
portion of the machinery. including the
immense Marcy mill. comes from Den
yer. the crusher comes from Milyau-
kee and the tanks from the Pacific
coast.
Extensive Construction
In all about 10 cars Of machinery
will he installed in the mill. the weight
of which. including electrical equipment.
aggregates about 700 tons. The larg-
est machine to be installed is the Marcy
mill. which when assembled and par
TALLY filled with the large iron "can-
non" balls utilized in its operation,
will weigh between IS and 80 tons
The largest single section of this mill
as shipped from the factory weighs
seven tons. In its elevation to the
mill site M the tram both the perma-
nent and electric hoist and the tenn
porary steam hoist will be utilized.
In the construction of the mill about
LOO cubic yards of concrete and $50
oNO feet board measure of lumber is
being utilized. In the preparation of
the concrete eight ears of cement and
10 cars of sand, the latter being ship
ped from Great Falls. and a large
quantity Of gravel secured along the
creek, will be used. All told between
90 and 20 cars of material and ma
chinery is being used in the mill.
All Of this machinery is hauled by
railroad either to Neihart, six miles
from the works, or Benton spur. at
the mouth of Carpenter creek. four
