"Snowshoes are worn by horses used
In hauling in machinery for the OrO-
grande Gold Mining company, OrO-
grande, Idaho," said r.. w. Bewley, SUI
perintendent, to Spokesman Review
reporter. The total weight of the new
equipment is 100000 pounds. 1t has
been necessary to take 1t In over the

'The snow is five feet deep at the
switchback, between Sites and Eik
City, seven feet at Newsome and 18
feet at the Mountain House, he said.
Horses have a desperate struggle in
the mountain roads unaided,
but when equipped with snowshoes
team hauls $500 pounds. The snow
shoes are about IL inches square. Their
use Is soon learned by the horses.
'.We have exposed face of ore 200
feet high above the mill level and 800
feet wide. Only few inches OF the
face would be removed In supplying
300 tons daily to the mill and while
ore IL not removed In that way the
statement supplies an illustration of
the resources, which can hardly be
exhausted above the mill level alone
in the present generation.
''To keep mining costs at the lowest
we viii break 1000 tons at time and
convey the ore from the glory hole to
the cars with steam shovel. The
haulage to the crushers will be but
800 feet for considerable period of
time
Not another property in the north
west will equal the Orogrande in
equipment for the tonnage to be han
died." said Superintendent Bewley,
who for many years directed opera
tions at the Republic mine and mill.
Five departments will be indepen-
Gent Of each other for the supply of
power, Pelton wheels have been pro-
yided for the operation of each.
Machinery On The Road
Construction on the mill Is well
under way. Foundations for all the
heavy machinery have been completed.
A Pelton wheel of 400-horsepower is
installation and the pen
tock Is on the ground. The pipe, which
has diameter of IL inches, will pro-
vide a head of 440 feet. 1t is 1920
feet long and will be connected with
the Pioneer ditch, which Is five miles
long.
'The equipment In transit includes
Danish flint pebbles, all of which were
to have left Sites this week, two tube
mills which are on the road between
Sites and Orogrande, four agitators,
II thickeners, two Dorr classifiers, nine
Dorr improved diaphragm pumps, used
In the elevation of pulp, and q 800
cubic foot Ludlow-Dunn air compress
Or equipped with feather valves to be
used In cyanide agitation. Tank ma
terial left the Union iron works this
week. Logs have been banked and a
saw1nill installed. All of the material
needed for a year will he sawed this
The method of treatment will be
straight cyanide by which recovery
Of 80 per cent of the gold will be
made, according to tests. Shipments
of the product will be made in small
parcels to the mint. The capacity of
the mill will be raised to 1000 tons
