A Trip to the Mountains,
NOTES FROM THR JUUNNAL OF A. 8. N.
From San Andreas we jeurneyed eastword.
On the way from the litths towu ot FE] Dorado,
we saw cunsiderable placer mining, mostly by
Chinomen. El Dorady isu wining town, but
there is little work being dune there at this
season of the yeur, on account of the searcity:
of water, [a pussing from KL Dorado to Duinving’s saw-nilla, we enw a great variety of
country —goiue parts quite level und finely tin
bered, and other parts monntainons nud barren
Near the wills are extensive clifls of argitla
cevus rocks, worn into deep gulehes by the action of water. Winding down a steep gride
over these rocks for more than a mile. gave us
a fine opportunity to examine its character.
From Dunning’s to Dunhar’s mills we had a
high mountain to climbover. For the distance
of two iniles the ascent is very steep, and our
tenm wus over two honrs in ascending it. The
forest trees by the wuy are large aud handeomo, consisting of pine, fir, andeedar. In
fuct, the trees tnereased in size and beauty tilt
they reached the climax in the “Big 'l'ree
rove. ‘fhe Big ‘Trees hnve been described
by mony who hnve visited them, but to gain a
correct idea of their greatness, onc must visit
them. ‘This isa delightful pluce for visitors—
benutiful valley, fine atmosphere, brook of cool,
running water from the melting snows of the
Sierras, excellent Rotel aceommodstions, with
a gentlemanly host. We do not wonder atthe
rapid growth of these trees, when we consider
the richness of the sotl in tho valley, the decomposing surface rock of the surrounding hills
coutinually furnishing nutriment for them.
About three miles south of the Big Tree
Grove, nre the “cliffs” on the banks of the
Stauislaus. ‘Tho perpendieulur rock is not
very high—not so high as we had anticipated
from the descriptions given ns—hut the seenery, standing on the sainmit of these eliffs nnd
looking dowu into the deep gorge and beholding the river rushing and foaming along down
its narrow windings, aad over rugged rocks,
thonsands of feet below. is snblime. Not even
Yo-Senite gnve as sueh an idea of vastness,
as this valley. The rock of the cliffs wna
formerly a crystafine formation, now auch
changed. We obtained from it some fiue
speciniens of serpentine. Several bundred feet
below the suanit of the eliffs is nn aqueduet,
which eonducts the water from the Stanislaus,
takeu frown the river some fifteen or twenty
miles above, to Murphy's, aud the country below.
At Murphy's, hydraulic miaing is carried on
quite extensively. -On the sonth side of the
village, and adjoining it, there is an ancient
channel filled with diluvium, which is worked
in some pluces to a depth of uearly one hundred feet from the snrfaee. he bed-rock of
the channef is limestone. The drift is rnised
by water-power with derricks. ‘Ihe water
which is used for washing the drift‘is supplied
by an aqueduct, situated on an adjoining hill
about seventy-five feet above the works, and is
conducted through pipes bve or six ineles ia
diameter, and fureed through a smaller pipe
upon the gravel. Mueh gold is obtained by
this process, and miners find it 2 very profitable employment.
‘Three miles northwest of Murphy's, at the
village of San Antonio, is located the Noble
Copper Mine. ‘This compnny has n fine steam
engine for working their shaft. which has been
suok tothe depth of 113 feet. he thicknéss
of the yein at that depth, whieh is found widening as it desceuds, is three feet. Work at the
mine has been suspeaded for some time, owing
to the death of the president; but it ts to be
regumed pretty sooa. ‘lhe specimens of ore we
eaw were of a good quality. ;
A short distance from the Noble is the San
Jose Copper Mine. A shn{t has been sunk for
a short distanee into the vein from the surface,
but tho compaay are now running a tunnel
into the base ol the hill to strike the vein.
From this tunnel wo obtained some fine specimeas of sponge-like asbestos—the finest we
ever saw. Ths Saa Josc elaim promises well,
and we believe will eventually prove a valuable
aine. Thereis also eonsiderable placer miniag
ia this vicinity.

Cause or Dawatza Livrrs.—Speaking of .
beer drawa through lead pipes, a eorrespondent
of the Chicago Mfedical Examiner says: “It

The North Almaden Quicksilver Mine.
This recently discovered quicksilver mince is ,
loented in Santa Clara cowry, about vight
. niles sontheast of Sau Juse,on the Farns-_
worth ranch, and ning miles uorth of the New
Almaden, ‘lhe lvcation is beautifully situated,ond wefl udapted tu mining parposes. At the
fuut of the mountain, und in close proximity 10
the nine, silver creck is to be fannd, nbunduntly supplied with a never. failing streau of pure
witer, aud shaded from the sun's riys by the .
female lnurel eutwined with the “bmve old
oak.”
The mountain, from summit to base, is promiseiously covered with cinnabar rock, prodneing from two and a-hulf to thirty per cent.
metal, und iudientions show this kind of rock
to exist in almost au unlimited quantity.
Enough has already heen discuvered to guarantee the erection of furnaces und a spirited
development of the mino. ‘here are twelve
hands now employed, with a practicnl miner
to superintend operations. Iiverything apPpeurs to bo working in the right direction, and
the pruspects of the mine are daily improving.
At the eastern part of the mine a shallow
tunnel is being run through the ledge. ‘I'he
object of this tunnel is to reach the hanging
wall of the lode nud ascertuin its underlie
before commeucing their permanent tunnels
and shafts. ‘This is as it should be, us there is
no doubt it wifl be the means of saviug time
and expenditure, ‘he tunnel has been driven
some twenty feet, and the cutting through of
the ledge looks truly enconraging. ‘hough
seureely over twelve fect from the surfaee, the
miners are, nevertheless, taking out u large
quantity of good average metal.
Prom this point of operation some distance,
to the west, there is a party employed in an
open cutting. Here is a point for the study of
geologists, In this cutting there is at least
eight feet of blaek elay lying on the ledge.
Out of curiosity, I had a wheelbarrow full
taken to the brook and washed, when, not a
little to my surprise, I found it eontnined fromsix to seven per cent. metal [mincrals?] How
is it that smull stones of metal [mineral 2] became so promiscuously diffused through this
black earthy matter? “Can it be what is too
frequently termed floa! metal ? or is it possible
that they were thrown up into it by voleanic
action? I would be glad to see the views of
some of your able correspondent: on the subject. This clay I spenk of is as nature forined
‘it, and is@ most excellent material to make
adobes with.
The ledge in this place has a somewhat different character from that of the portion
drivea through in the tunnel. Theroek in the
tunnel is of » dark brown color, coated with
lime, and, f would Suppose, fumes of quieksilver; whilst the ledge rock iu the open cutting
possesses every attribute to be found in the
roek at the New Almaden mine, to a eertain
depth. In fact, I find indications here precisely the same as I have seen them in other
quicksilver mines, and with mueh greater facilities for taking out the metal.
The miae is as yct in its infauey ; nevertheless they are taking out large quantities of
quicksilver, and I predict that in six months
from this tiine quicksilver will be made for less
than one-half the cost of any other quicksilver
mine in the State of Culifornia.
Remarxs.—Accompanying the above, we
reeeived a very fine specitaen of the ore taken
from the “East Tunnel.” We do uot fully
uaderstaad onr correspondent’s deseription of
the “black clay” deposit, and its accompanying “metal.” By “stones of metal,” we are
led to infer that the aetalliferous substance
may be a sulphuret of mercary, whieh, by
their superior resistance to abrasion, have remained entire, while the more softer material
which has surrounded them has been reduced
to clay, colored, perhaps, by manganese, or by
soms vegetable substnnee. However that may
be, the clay must be a secondary deposit, aud
not an original formation, ns our correspondent
appears to intimats. Perhaps at some future
time we mny have the pleasure of visiting the
locality, and onswering, more definitely, tbe
questions of our correspondeut.

Jottings from the Mountains,
BY AN OCCASIONAL CORAQESPONG@ENT.
Byron says there is nothing so difficult as
finding a beginning for u story, unless it be the
ending; and it now ocenrs to me, that one
rarely reads n letter af earrespondenec, these
modern duys, that does not open or close with ;
reinurks touching the vicissitudes of climo aud
climate. But I shull not bore you on this head.
this is July, with a sky of hrass aver head and
the notmosphere permented with fine dust.
Moving nbout the country by public conveyance, under such circuinstances, is by no means
pleasant, even when journeying holds_out the
inducements of profit.
IDRANATEA,
For the reasons nssigned, since I came into
the mountoins—althongh it wns my full deter:
minntion to makea thorough exploration of
ths mines, particnlarly of this loenlity—I have
remained,as the coon said, “treed, and kept
my hole.”
These contemplated explanations wers not
to he undertaken with any expectation of enlighteuing the world, but only to gratify the
curiosity of a greenhorn in mining matters,
who holds to the axiom that nll knowledgs is
profitable, and that there is special pertinency
in becoming familinr with sueh objects of interest as are paramount in the section of
country where one sojourns, whether it bo for
a protracted or bricf period.
A GENERAL LAMENTATION.
“ Yard times” ig in every mouth,and discouragement pervades all’ coinmunities. And
why? Because the harvest is abundant, but
the reapers are few. The mines are numerous
and teeming with the wealth of hidden millions ; yet there is no capital to develop them.
Californin is no longer hyperion in the mining
constellation. Not that her mines are giving
out; on the eontrary, the country has not as
yet been half prospected. But the honors ore
shared with her by regions in which aew diseoveries have been made. Her population,
with that love of excitement which has always
rendered the early explorers of the State uneasy, even while their prospects were the most
encouraging, have repuired to Idaho, Reese
River, Washoe, Esmeralda, Colorado, and other
remote regions, and earried with them a great
deal of the capital whieh otherwise might have
been used here towards the development of
the State’s resources, and the euriching of
those who possessed it.
CASES IN POINT.
Placerville, it is well known, is in the very
eenter of the richest quartz mining region of
California, if not of the world. ‘The gold-bearing belt eomes down from tbe region of Grass
Valley, in Nevadu eounty, and embraeing El
Dorado county, sweeps as far south as Tulare,
and contains mines whieh linve already yielded
amounts of the preeious metals that would be
deemed fabulous. if we did not have our yearly
shipments to point to in proof; most of tbe
gold from which. since the placer diggings are
almost a thing of the past, has been exhumed
from the deep bowels of our motber earth.
MINES WITH REPUTATION.
If the reader knows anything xbout El Dorado eounty. he: has heard of the Manning,
Harmon, Haywards, Hinchman, Union, New
York. Pacific, KE) Dorado. and other nlmost
equally fumous ledges, which have given eharneter to the county, and must hereafter prove
tbe soaree of its permanent wealth.
TAKE ONE OF THESE AS A SAMPLE.
One of these mines, aad only one, thns far,
T have visited, explored, and inquired about.
Indulge me, therefore, while I speak of it. I
allude to the Harmon. ‘I'his mine is located
on the west side of “ Quartz Mountain.” about
a mile nortb of Plocervilfe, nearly on the line
of the Pacific Raiload. It has been opened
for several years, although I am iulurmed only
worked with success two yenors of that time.
A tunnel has been put in 350 feet, and a shaft
sunk eighty feet. A fifteen-stamp mill, with an
eagine of tweaty-horse power, all in eomplete
working order, aro oa the ground. There is
also a large aad well built hoarding house for
the workmeu. Between $15,000 and $16,000
have been expended on these improvemeats,
and $29,000 have been taken ont of the mine,
sufficient to justify the trustees in deelaring
two differeat divideads. The ledge is twelve}:
feet wide. nnd the rock whieh is Taken froin it
has thus far averaged nbout $40 to the ton. 1
have several pieces befure me, with numerons
particles of gold visible to the naked eye.
The stock of the Hurmon has been quoted in
the market as high as $50 per foot, and is perhaps worth five times that mueh to-day.
wuy Not?
Why will ths stock of such a mine not
biting a price in some degree commensurato
with its value? “‘Vhe nuswer involves just such
a state of affairsas Lhavespuk nof. There is
not eopital enough tn the cour try te meet tho
demands of one-tenth part of the mills ond
ledgea. ‘This mine, umong others, must lie
idfe notil there is mouey inthe country to
work it.
ITS PRESENT connITION.
The rock of the mine grew richer as the
shaft went down. The water line wos struck
nta depth of forty fect. The vulnine inereased
ns the shaft descended, until it was found impossible to clear the mine withont steam-power.
‘The company had, besides, managed the afairs
of the mifl and mine bodly, Mr. J. W. Epley,
who was a large owner, seeing how things was
gotng, and knowing the mine to be immensely
valuable, in self-defense purchased a chief
part of its stock; but by doing sv, expended
so much of his avaifuble means as ta be nuable
tu proceed with the work at the present time.
LET US NAYE CaPIrAaL.
If this mine—and I name it only because it
serves as an example—with its splendid goldstudded rock, is compelled to remain anworked
for the want of a few thousand dollars, what
show is there for thoss ledges which possess
no such advantages ns mills, in good working
order, boarding houses, fine reuds, nor lie in
proximity to populous towns aud cities ?
We must have more eapital. Mr. Editor,
appeal to the millionaires of the East who
have realized sueh vast fortunes in oil, and see
if you cannot induee them to come up into
this rich mineral regioa and invest.
Homen,
Placerville, July 28th, 1865.
NEW PROCESSES,
The latest new “ process” which we have
noticed, is termed the “ Wilson Process.” It
is described ia the New York Stockholder as
follows:
‘The process consists of a scries of fire-clay
retorts, eylindrieal in shape, and arrunged one
above the other, and all iaclosed and made to
revolve in a large furnace, the fire beiug applied below, the heat and flame passing up and
arouud the cylinders. These cylinders are
heated to a cherry red, when the sulphurets nre
introdueed into the top one, which is so constructed as to automatically discharge into the
one next below, and so on through ths series,
the last discharging into a water-batn. During the process a current of air and steam
combined is cnused to eonstantly intermiugle
with the ore, causing a more perfect oxydation.
The construction and operation are such that
no loss caa ensue from vaporizatioa or currents of air, as in the ordinary reverberatoryhearth. The whole arrangement is compaet,
and not very expensive. Crushing and triturating machines aceompany desalphurizing
machiues when required.
Another method, brought forward by an experimenler in Newark, pulverizes the ore aad
submits it directly to nitric and muriatic acids,
as being the solveats of gold. All the gold
thnt is touched by them, and nll the other base
metals, nore readily dissolved. ‘The solutioa is
thea poured off, and the yariougs metals in it
are precipitated by different, chemical substanecs. A portioa of the process is kept secret
by the discoverer; but the aain poiat is the
dissolving the gold in aqua regia. The proeess has the merit of dispensing with quicksilver, but at the expense of large quantities
of costly ncids.
Torumen oF Yankee Grexivs.—At a recent
trial of breach loading gaus at St. Petersburg,
Russia, in presenee of a deputatioa of high
officials, after the rejection of the English
made guns of Clay, Whitworth and Armstroag
patterns, aad a trial between Prussia and
Berlin guns, aad one invented by an American
‘named Broadwell, the latter was adopted as
preferable and more perfeet than nny of the
others. The London Mechanics Magazine
urges the English Government to alter the
) Armstroag gun to Broadwell’s patteru.
Tre cessation of hostilitics allows Government to save thirty-five millions of dollars
per aaaum in the single item of coal.
Soucar rrom Aspen.—At Soult Lake, sugar
is made from boifing tbs sap of the quaking
asp. ‘The process is similar to that ot
makiag sugar from the sap of tho maple.
