1000 feet, which is located on ledge lying
on the lower side Of the rayine which runs
down close to the Jewett and Sheppard
claim. The ledge of the Jura is worked
through tunnel, which is started IN from
this ravine, and runs west to the ledge Inc
entrance % this work is about forty rods
TO the northwest of the Jewett and Sheppard
shaft, and about the same distance nearly
due west from the upper shait OF Ihe hn.S
erbocker claim. This tunnel Is now nearly
six hundred feet long, and has for the most
mart Of the way been run through hard rock
which had 10 be blasted, and had, IN places
where the rock did not require this, required
the sledgc. and the cad had TO be freely used.
II nearly straight. Some curves are mace
in II. but nothing which will take II tar tr! m
a west course. The tunnel came to ledge
at the distance of $50 feet from its mouth.
Before reaching this ledge the tunnel passed
through quite 4 space OF ground whleh was
broken up considerable, and which contains
large quantities Of quartz. No stratum OF
quartz which was sufficiently dehned to be
called a ledge was found, until the tunnel
come 10 the one lust mentioned. This ledge
is generally narrow, being in some places
only 4 few inches in thickness, but in others
widening out TO be two, three and even four
feet thick. The quartz is Of 4 white and
brown colo-, and when being IN the dump
pile the mass presents the appearance
also of being much the same color.
The ledge runs nearly north and south, which
makes its course at right angles with that OF
the tunnel. The company has drift run
along on the ledge both north and south. 1t
extends in the former direction only about
% feet, and for that distance the ledge IS
found 10 be quite narrow, out Of very good
quality. The drift 10 the south Is much |
longer. Il follows the ledge in that direction |
about $50 feet and nil this distance 1t Is found
TO keep the same direction and to have the |
same clip, or pitch, which is to the east at an
angie OF abCu. fifteen degrees from the per-
pendicular. Il is narrow for the first twenty
hye or thirty feet from the tunnel, where It
commences 10 widen out, and at about nifty
feet from that work is found 70 be nearly or
quite four feet wide, which is the thicSest
place Of the ledge that has vet been found.
The drift was run on beyond this point about
100 feet, when the air became so bad that
some means OF ventilation became necessary
to be made TO enable the miners TO work.
The plan adopted TO provide FOX the yentila-
ton of the mine, was one which would pro-
vide circulation of air, and which would
at the same time develope the ledge. 1t was
10 work an incline upwards from the end Of
this drift to the surface OF the ground. This
was accordingly done, and the distance proved
TO be only 1871 feet. The air in this incline
was very bad, as might have been expected,
before this work was ACCOMPLISHING bad,
in fact that single candle would not burn,
and several had TO be placed together 10 keep
a light. All this labor and trouble was am
ply repaid by the accomplishment OF the task,
a. -. =
air circulating through the works which
is exceedingly pleasant, and which carries |
away the powder smoke, after blast is put
OF, and enables the wOrkmen 10 keep steadily
al their labor, and to do much more than if
the air was hot, impure and confined. In |
this drift, about fifty feet from the tunnel, at
the point where the ledge is the widest, the
company has commenced TO sink shaft. |
They. have had chamber cut out, about ten !
feet square, which IS timbered over head, and |
have sunk shaft which IS now four and |
half feet square and SIXty-hye feet deep. This |
shaft was started directly on the ledge, and it |
is the intention OF the company to sink it 200 |
feet deep, and then drift to the ledge which |
will be found at that depth, not 4 very great !
distance from the bottom rs its pitch from the |
line OF the perpendicular is not great. Tne |
work in this mine is carried on under the |
superintendence of Mr.. VIM. Welch, who |
has certainly exercised a great deal Of good !
judgment in laying out the work. It has |!
been carried on in such q manner that there |
has been no labor thrown away. The tunnel /
is run straight 10 he ledge, and then DRIFT 1
has been run on that, and as 1t has been |
driven forward, the p2y-rock has been saved. /
When the air shaft was constructed, the \
whole depth Of It was through the ledge, so |
that all the work which has been done has re-
18Th 20, ,,roe-acrirFr tho - aud
ducing pay-roCk. The Superintendent in
forms US that there has been about i've tons
of this rock crushed, which yielded about
500 per ton, mostly in gold. On the dump
there is deposited several tons more which
has been taken from the ledge when running
the drift. This ledge, We think, will grow
larger when it IS worked down upOn, and If
il does, will be quite valuable. At the present
level, We DO not think it will average more
than fifteen or sixteen inches in thickness,
but as it is quite rich and well defined, it
may, by good management, pay something
more than expenses, If worked from here.
LEON CoMPASY.-The claim Of this com
pany contains !, 200 feet which are located on
the front Gold Hill ledge. The company
works the claim, BY shaft which is sunk a
few rods north Of the Belcher Company's in
cline, and about half way between the Gold /
Hill school house and the American Flat
road. The working Of the mine is carried on |
under the direction OF Mr.. ]. Biggs, practi-
cal miner, who has had much experience in
mining, both in this Territory and in Califor- |
MIA. The workmen are now engaged in sink
ing the shaft on this claim deeper. Its depth |
at present is us feet, and the shaft is four |
by eight feet in size in the clear, timbered |
with three-inch planks, and divided into two /
compartments Of equal size. The shaft is |
worked by means of a common double wind /
lass which has i drum little upwards of
eight feet long, which is placed over both 1
compartments of the shaft and has attached |
to it by the rope which it coils and recoils, |
two buckets, one in each compartment Of the |
shaft. When one bucket is being hoisted
the other is descending, and by its weight
balances so much of the weight OF the other
and makes the labor of raising it much easier.
The depth OF the shaft is such that the la
Dor Of raising the rock and earth from the
bottom Of it IS very heavy, and the buckets
have to be loaded very lightly. This makes
the work of hosting both constant and slow.
At the depth Of about 50 feet from the top,
a drift was run TO the west about 60 feet from
the shaft, when 1t struck the ledge. No work
was done in this drift more than to run It to
the ledge to ascertain its exact location, the
direction which it runs, and the way which it
pitches, so that the work on the claim might
thereafter be regulated accordingly. Since
that drift was run, the shaft has been sunk
more than hundred feet deeper than it was
then, and the intention Of the company is to
sink down to the depth of about 200 feet, and
then drift to the ledge, which was run to with
the drift above.
YELLOW JACKET MINE.-The new ma
chinery which is to be added to that which
this company have already erected, will be
put in operation in the course off couple of
weeks. The castings, which were made at
the Fulton Foundry, are complete, and all
that is now wanting is some blacksmithing |
to be done to make the parts complete to be
put together. The machinery is to be erect
ed for the purpose Of working the shaft
which the company is now sinking near the
mouth Of their incline This is now about /
ITO feet, and is being worked by common
