A MINING AND AGRICULTURAL
COLLEGE.
Among the most important acta of the late
Miners’ Conveation at Sacramento, was the
good degree of uaanimity displayed in favor of
the establishment of an Institute in this State
having for its object the teaching of the sciences bearing upon the two great leading pureuits of miaing and agriculture. In furtherance
of this project, a scries of resolutions were
adopted recommending that the Legislature
proceed at once to the establishment of a
“Mining, Agricultural and Mechanical College.” ‘he alacrity aad unaaimity with which
the agriculturists have come forward, and united with the mining interest ia the furthcrance
of this movement, even to the sacrifice of what
may be cousidered their own more especial
claims npon certain grants and funds, available
for anch porposes, cannot fail to elicit from our
mining friends a high appreciation of the generosity displayed in thatact. It isto he hoped
that the movement so nobly inaugurated, may
lead to a still closer union of the two iaterests,
each of which in this State is eo peculiarly
dependent npon the other.
At some future time we propose to discuss
the bencfit which the agriculturist must derive
from snch an institution. It is our present
purpose, however, to speak more particularly
to our miaing readers.
The iniportance of the establishment of
schools on tbe Pacific Coast for instructioa in
mining is now pretty generally admitted, so
much so that itis scarcely necessary that we
should stop, at this time, to discuss that portion of the subject at all; and we shali chiefly
confiae our reaiarks in the preseat and perhaps
one or two future numbers, to the character
of the instruction which should be rendered.
In conversation with centlemen who have
had mucb experieuce in European miues and
miniag schools, previous to coming to California, we have been told that cven the most
expericuced and skillful miners from that coatiaent need a local education here—they fiad
it necessary to introduce certuin moditicatious
into their European practice and education,
which are iadispensable to the altered condition of things here from what they have beea
accustomed to encounter there.
Gentlemen who are sending their sons to
Paris, Freiburg, etc., to obtaiu a knowledge of
mining engineering and metallurgy, will fiad
on their return that onr varied resourecs, increased cost of labor and material, peculiar
character of machinery and different hahits of
thought, will render nugatory to a great extent,
the application here of the practical portion of
their Enropean education. ‘The theory, of
course, is the same everywhere. The character of the macbinery employed here is most
essentially different from that employed there
—and in almost every particnlar is greatly
improved.
Our stamping mills, for instance, are a long
way in advance of the same class of machinery
there. Any person who is acquainted with the
stamps ia use in both localities, must admit
tbis fact. The revolving stamp, unless quite
recently introduced, is unknown there. Almost
every particular with regard to the construction
of the stamp, mode of discharge, etc., has been
improved iu California, until our hatteries are
now doing nearly or quite double the duty, per
head, of those employed in Kurope. Ls
Agaia, our admirable paa system is entirely
unknown in Europe, the nearest approach
heing the Hungarian howl ; and when we contrast the cnmbrons German steam engine with
the light and effective engines used in Califorvia and Nevada, we must set down onr Teutonic friends as full half a century hehind us.
Our hoisting machinery, for the depth we
have gone,is decidedly superior to the generality of that employed iu Europe. Ounr
safety cages are greatly improved over those,
elsewhere employed, in lightness, effectivenessand safety. We have heard it stated by competent judges, of foreign birth and education,
too, that some of our best hoisting works, such
as those employed at the Yellow Jacket, Savage, Gould & Curry, etc., are capable of extracting douhle the amount of ore raised at any
niine on the European continent.
Tn onr efforts at “progress,” we may at times
have overstepped the hounds of economy, and
accomplished a large amount of work at considerable unnecessary waste of mineral; but we
have gained largely in experience.
Tn the metallurgy of silver, though our expertments were at first attended with heavy losses.
we have now arrived ata point at which we
ean learn hut little from European seliools, that
will be applicahle to our local peculiarities and
necessities.
In the assaying hranch of nictallurgy we are
somewhat at fault—in analytical chemistry, in
particular, we frecly yield the palm to furopeau
Professors ; but as practical assayers we claim
a full equality with citber our German or Eng”
lish cousins.
In relation to uuderground engineering, our
miners are not as thorough ag they should he;
but this deficiency arise more from our national character of go-ahead-ativeness—our cure
for the present only, at the expense of tbe future—than from a Jack of knowledge for
thorough work. With respect to subterraneous
surveying, the German miner's dial, a sample
of which may he seea at Sack’s, 203 Montgomery strect, would indicate that the Frieberg
schools have made but little proyress for the
last half century at least. The most indifferent of our mountain county surveyors would
not use sucb an instrument.
As weare writing at this time in favor of an
agricultural as well as 9 mining school, it may
not be out of place here, to allude to the uniyersally acknowledged fact that our Huropean
friends are most sadly behind Americans in
the practical departments of agriculture. As
a proof of this we ueed only to point to the
records of our patent office, aud call attention
to the contents of our avricultural warehouses,
. filled with mowing and reaping machines,
threshers. steam ploughs, ete.,a class of me
chanical appliances almost unknown in Europe,
where agriculture was carried on for ceaturies
before America was discovered; but whose
fields, even to this day, are chiefly supplied
with American machinery,
From the ahove facts may be adduced the
Most unanswerahle argumeats in favor of the .
establishment of an American school, where .
young American men may be taught the use
and employment of American machiuery, and
where such ideas may be instilled into the
minds of students, as will not have to he zlearned before they can put their theoriee into
practice.
‘he students of hoth agriculture and mining
will find a larger and hetter field for practical
instruction at home, than it will he possible to
reach in Hurope. Let us then found, -nourish
and build up on our own soil,an Institute for
instruction in those sciences, which shall be
adapted to our peculiar local needs, and educate our young men at home, instead of spending thoueands of dollars abroad, much of it for
that which must he unlearned wheu they get
into actual practice. We hnve much: to sny
upon this subject, which we ehall endeavor to
give, from week to week, so long as the subject of the establishment of a California Mining and Agricultural College shall he under
discussion before the Legislature.
IMPROVEMENT IN THE PHOTOGRAPHIO
From the first introduction of the ‘photographic art tothe present time, it has ever
been the constant study of the artist to improve in their efforts to
life-like aspect to their pictures of tbe human
fyce. Much has already heen accomplished in
years past ; hut we have never seen a greater
advance in this direction, apparently at one
step, than has recently been made hy Messrs.
Bradley & Rulofson, as exhibited iu some admirable pictures recently produced by them,
and now ov exhibition at their gullery, 429
Montgomery street. All artists have been
painfully cognizant of the fact of the difficulty
of ohtaining a good picture of persons who are
not possessed of fair complexions, or who may
possess even the slightest imperfection of
countepance. In the ordinary processes all such
imperfections ure unavoidably exaggerated.
By the peculiar action of the rays of light, even
a faithful picture is unattainable, and recourse
is had to artificial coloring and re-touching,
whicb, in the best hands, is hut 2 bungling imitation of what Messrs. Bradley & Rulofsoa are,
hy their improved process, enahled to accomplisb hy the unuided pencil of light.
So far may this process he carried, that even
nature may he eclipsed, and the wheels of time
rolled hack by the steady and guarded action
of the raye of a single day’ssun. Under the
skillful direction of these gentlemen, the action
of the rays of light alone is made to wipe out
“spots ” and harsh shadows froa their pictures,
to remove the wrinkles of age, aud give fresbness and heavty to the face aad contour,
wherever that bas once existed in the original.
Mach of this may appear impossible, and
would he so tous had we aot eeen tbe evidence, and, to a certaiu extent, learned the
proeess by which it is accomplished ; which is
nothing more than an ingenious application of
some of the simplest principles of optics. Our
res.ders are all aware of the syperiority of the
stereoscopic picture over the ordinary photograph; we helicve we are giving no clue to
their secret when we say tbat every one of
Bradley & Rulofson's improved pictures consist
of asepurate stereoscopic representation of every
mathematical point on tbe eutire surface of the
picture, hleuded in one harmonious whole, ia
soch a manner as to bring out the object with
a heauty of finish, roundness of feature, and
life-like expression, totally unattainable by aay
other process known.

THE AMERICAN FREEDMAN’S COMMISSION,
It is much to be regretted that any portion
of the Culifornia press should be found treating with levity the efforts in hehalf of the
jgreat national philantrophic movement, now
under the direction of the *‘ Anierican Freedman’s Commission.” With the exception of
theimmediate necessities of active campaigning, during nur late terrible wor, the world has
never presented sucha necessitons field for
active and earnest philanthropy as is embraced
ia that occupied by this Commission. It is
not a work sought out hy officious philanthropists,asa field in which to exhihit their humanitariaa efforts; bat it is a great, home
fact, thrust upon the American people hy the
“logic of events,” and they will richly earn tbe
scorn and contempt of the world if they ignore
it. Sympathy for the colored race is not, de
Facto, its foundation—the bed-rock upon which
action, by those not in sympathy with that
race, may reasonably he founded, is tle welfare
and protection of the white race at the South.
Crushed by the fortunes of war, irritated by a
complete revolution in their social condition :
peace has nuturally enough found them, as a
people, neither able in purse or disposed in
temper to control the disorganized social element hy which they are now surrounded. It
would he less than human for the people of the
North to refuse, in such a crisis, to lend a
belping hand in their deep distress; and the
man who would turn honest, well-directed
effort in sucb hehalf to ridicule, would laugh
at the direst calamity which could hefall his
neighhor. No work of sucha vast scope can
he carried on withont union of effort, and well
arranged machinery. To a great exteut the
same men are engaged in this work who have
acquitted themselves with so mucb eredit and
fidelity ia the great Sunitary Comanission, the
necessity of which has now passed away. So
far as the public are informed, all cngaged in
this new work are men of unimpeacbable
reputation ; and they should be sustaiaed hy
all the aid and encouragement which a generoue and humanity-loving public can bring to
hear.
In this connection, we would call attention
to tbe announcemeat that there will he a meeting of the friends aud membere of the Freednieu’s Aid Commission for this coast at Platt’s
Hall, ou January 29th, in the evening of that
day, for tbe purpose of publicly inaugurating
the officers, and ratifying the measures heretofore taken for the organization of the association here. Honorshle Cornelius Cole, Hon.
A. A. Sargent, Rev. Horatio Stehhins, Rev.
Jesse Peck, Dr J. ¥. Morse. Gen. John F.
Miller, F*. Billings, Esq., and Hon. Thompson
Camphell, will address the meetiug.
