in length. The paystreak is from
= inches to 3 feet wide of the
same hard gray carbonate of lead
as that found in the Silver Rule
mine. 1t gives average values
OF 90 to 20 per cent. lead, and so
to 500 ounces in silver and IS to
500 in gold. There has been
several carloads of selected ore
shipped from this mine, that
yielded over go per cent. lead and
300 ounces of silver per ton.
On the opposite side of the
divide, two miles distant, the
same Denver people own another
property, which they call their
low grade mine. There is a large
vein of sand carbonate, and galena
ore, associated with some zinc,
and carries big, strong shoots of
clean ore-2 to s feet wide-that
yielded average values of so to
go per cent. lead and 90 to 40
ounces in silver.
The Salmon River range or
aggregation of rough mountains
and canyons, which divide the
waters of Middle Fork from the
main Salmon river, and extend
from the head of Cape Horn
creek to Shoup, a distance of rs
miles in an airline. contain num-
erous districts and belts of min
eral besides the one just describ-
ed, and their various mines have
a bullion record of not less than
S50,OO0 O0,0OO. Of this magnificent
yield, fully 30 per cent. was in
gold, Is per cent. in silver and )
per cent. lead and copper.
The baser metals in this reg
ion have been avoided anc
neglected principally by reason
of lack of transportation facilit.
les. But if the present CONNER
cial magnifcence of the United
States continues, the extensive
deposits of copper, lead, iror
and other useful metals here
unaffected, will doubtless sool
attract the attention of capital
lists, and form the basis of larg'
industrial enterprises.
The prevailing formation o
this range is granite of varyin:
types, from fine schisty gneiss T.
the coarse birdseye variety, witt
porphyritically developed crys
tails of orthoclase fieldspar O
extraordinary size-from 2 to
inches in the direction of thei
vertical axis. The prevailin.

creek placer district, west of tn
great volcanic peaks of the Gus

, is a large area of country show

to the Pixies Peak and Crippl
Greek type.
