believed that tbs Northwestern rail-
road is back Of the enterprise and
that the survey will be continued
down the Salmon river canyon to Its
confluence with the Snake river.
This Is one Of the most natural
routes for a trans-continental line
that is left unoccupied In the west.
and traverses one OF the largest ter.
ritories now undeveloped by railway
facilities in the United States.
From Salmon City the Salmon riy.
er iiows through canyon $50 miles
long that departs less than 20 miles
from due east and west line In that
distance Compared with the Snake
river canyon, which Is now being &C.
cupied by the Short Line from Hunt.
ington, the Salmon river canyon af
fords a comparatively easy route for
railroading. The river carries a
large volume OF water and has a fan
OF 1900 feet on $50 miles, which
could be harnessed to produce an
enormous amount OF water power.
1t trayeTses rich mineral territory
the entire distance and its numerous
tributary streams would produce an
important amount OF mineral traffic
and the consnmmation OF such an
enterprise would prove wonderful
stimulant to the mineral and bust !.
ness development of Len,hi county in
general.
Southeast from Salmon City, up
the Lemhi valley, there are several
promising operations and prospects
on numerous tributary streams that
put into the river fion the main
range. At Junction, so miles above
Salmon, the lead-silya belt is
reached. At this point the Lead
vile mine Is now making an impor.
tant production and hassix cars of
high grade silver-lead ore ,n the way
TO market. This propertyis named
after the famous Colorado district by
reason of its geological similarity.
1t is situated near the foG OF the
FIRST uplift from the broad, at valley
OF the Lemhi, two miles eat of the
Junction settlement. and cOsists of
a fat dipping contact depsit of
black locking. fine grained gaena and
lead carbonate ore containig good
values in silver and gold. II Is de-
veloped by shaft 100 fee deep,
from which two levels have ben run
$50 feet each. There is ais adit
level 1926 feet long. The ore aries
traces of anthony. which give it Its
dark color and makes it desiraie for
certain metallurgical purposes b the
treatment Of lead ore. This inter-.
secting ore deposit occuIs ur1er a
bed Of glacial gravel consisting OF
loosely agglomerated lime pobles.
The immediate hanging wall indei
this loose surface covering Is a
tough, reddish clay, varying Tom a
few inches to foot or moe In
thickness, next to which the glena
ore occurs in paystreak vayine
from a few inches to four fec In
thickness that contains so to Gpel
cent lead and 40 to so ounces avel
with three to four dollars goldpe
ton. Under this grayish anc al
tered limestone carries concen at
ing values of five to twelve per en-
. for as much as 30 feet wide at IN,
point. The limestone gradull,
hardens into pure blue carbonifelu
limestone as it recedes from b,

have already developed on the up
