Description of Equipment, De-
veIopment and Productive
Ability of Veteran Mine.

The great undertaking at the Veteran
mine of opening the immense ore body in
shape for the maximum rate of produc-
ton through the new shaft by means of
the big electric hoist is almost completed,

900 feet southwest from the big one. the
ore body was thoroughly prospected by
means of many levels. crosscuts and
raises, after which the location of the
new shaft was decided on. and ii was

size. and is timbered with heavy square
sets to the bottom. The head-frame Is
built of large-sized timbers and rises about
100 feet above the collar of the shaft. The

bins underneath. The bins are built over
a railroad track, on which cars are run
under the bins and loaded with from forty
to sixty tons by opening the gates con-
trolled by a wheel. The capacity of the
bins is about $500 tons.
Methods of Mining.

From the collar of the shaft to the top
of the ore pockets below the main level

deeper in order to construct the
pockets which have a capacity of nearly
800 tons From the time the ore is broken
it will be handled by automatic machinery
and gravity until the metal is cast from
the converters at the Steptoe plant
The system of levels. crosscuts and
raises that have been planned. with the
view of extracting the ore by the cavlng

That would be enough to furnish the
three units of the concentration with all 1T
could handle or 1900 to 5000 tons day,
but as the Cumberland-Ely has only a
haIf-interest in the plant, the maximum
output until more units are constructed

which will treat the high-grade ores with

never be more than about $3.50 tons.

June to the middle of July, the average
amount of ore sent to the smeiter was
so tons a day, or the rated capacity OF
eleven railroad cars. The cars are usual
ly loaded little in excess OF the marked
capacity, and the average OF all during
the month of June was 10000 pounds,
while one car carried $4,000 pounds. In
addition to the ore shipments. the mine
is sending some silica to the smelter-

which work is about half completed.
THE village of Veteran has the big
boarding house that will accommodate 400
at tables and several large bunkhouses, as
well as twentyseven cottages, that are
occupied by families. There is a wait
ing list of applicants for cottages from
men who desire to bring their families to
live near their work. The cottages are
rented at the rate of SO a room per
month.
Big Force of Men.
