LOCAL MINING ITEMS.
The mining stock market during the
past week was in q terribly demoralized
state. The sales in the San Francisco
Stock Board aggregated S7l4,ooo, and
there was not only a large decline in
values, but also a decrease in the vol
ume Of transactions. On Thursday,
however, bottom was touched, and since
then there has been a slight general ad-
vance, with o present struggling upward
tendency.
LADY BRYAN
The new mill Of the company, just
completed at the mine, started into OPP
GRAFTON yesterday morning at 10 o'clock,
and so perfect is the machinery that 1t
worked from the start as well as though
it had been running for months. 1t is
erected on the bank of the rayine a few
yards east of the ledge, in g very favor
able slopipg location, allowing o. the
ore cars from the mine being dumped
directly at the batteries, and afterward
in its successive degrees OF m%anipula-
ton passing through the mill, 1t is
constantly on descent, there
fore handled with the greatest
possible facility. The ravins below the
mill is also extremely favorable for
blanket sluices, dams and all varieties
Of tailings saving appliances. The
building itself is very neatly and sub
stantially constructed, the main portion
being ~ feet in length by 40 in width,
with a boiler room on the north side, 20
feet by 40 in size. The machinery was
all erected and put in working posi-
ton under the special supervision OF /.
F. Thompson, the well known mill
wright and engineer, and is Of the most
substantial and approved description
throughout, being possessed OF all the
latest improvements in every respect.
The ore is first passed through one OF
the largest sized Blake rock breakers
which reduces it to the size OF walnuts
and less, and then it passes by a very
ingenious seif-feeding arrangement into
the batteries. There are two FIVE stamp
batteries-each stamp weighing $50
pounds-capable OF reducing over so
tons Of ore daily. The grinding and
amalgsmating is done by four OF Nc
Cones mammoth pans, each Of which
works 5000 pounds, of pulp At q charge,
occupying four hours. There are two
huge settlers, one ten and the other
nine feet in diameter, and each three
feet deep. A very good feature in this
mill is that there is plenty Of room
under tho pan floors and batteries, so
that tho machinery can be got at for re-
pair, or any other purpose, with the
greatest facility. The whole is driven
by an excellent horizontal engine, with
t~velve-iuch cylinder and thirty-inch
stroke. II rates IS horsepower, but IS
capable Of being speeded up to over 60
horsepower when required. There are
two boilers, each "a inches in diameter
and l6 feet long, and all the water re-
onired for steam or the use Of the mill
is beautifully furnished from the lower
norton of the mine itself, being pumped
on. by the hosting machinery. The
r.tort at the rear end of the mill is out
side Of the building, and in order to
produce the requisite draft for the fur-
mace, as we'll ss to carry OF the delete
rious fumes Of the quicksilver, the
chimney fiue is connected directly with
the smoke stack Of the mill-a most ex-
cellent idea, which other mill proprie-
tors might adopt with great profit and
advantage. Taking it altogether, this
is the best mill Of its size and capacity
we have yet seen in this State.
The Lady Bryan mine, although
worked for years, has uersrbeen brought
into the productive condition that it is
at the present time. II has been con-
sidersbly prospectsd, yet the regular
psy streak never was struck until within
the last few months, and under the
present management this is being thor
oughly developed and made to bounti-
fully yield up its rich stores OF silver
bullion. Henry Donuelly, the new SUI
p~eriptendent of both mine aud mill, is a
gentleman Of much experience in that
line. both in this mine and en- the Com
stock, and is bringing his best energies
practically aud efficiently to bear in the
matter. The present working SHAFT IS
no feet deep, but the ore extraction Is
altogether from the surface down to the
so.foot level of the shaft, the pay streak
being about II feet in width. The ore
is hoisted from that level, and also run
out by tunnel from the surface, some 80
miners being employed, exclusive OF
surface hands, engineers, etc. About
GO tons of ore per day is the yield OF
the mine, averaging from $50 to $40
nar tom, although some Of it u n much
richer. 1t is generally Of the green
chIor;de character, occasionally inter-
spersed beautifully with free gold, plainly
visible to tho naked eye. The cost oil
mining Is about three dollars per ton,
and with this new mill it ia calculated
tb.t the milling of the ore can be done
for less than SIS per ton, thus leaving so
good a margin for profit that there IS no
GOOD reason in the world why the Lady
BRYAN should not soon become a regular
dividend paying institution. The bot.
tom of the shaft 10 in the east side OIL
the ledge, and at that point o drill west
develops the same good pay streak ex-
i,tipy at the level above. From the So
foot level down, however, the shaft is
to be repaired, which will occupy the
next two weeks, after which it is to be
sunk 200 feet deeper, all the way in
quartz, as the ledge is nearly or quite
500 feet wide. In the present working,
at the so-foot level, the main DRIFT in
the paw streak has been run so feet
nor,b from the shaft, to where the streak

in that direction as yet. The direction
of the main ledge is north aud south,
with an east dip Of about As degrees

mill, in Six-mile Canyon, u very ezees
