« InrenestiIna CoLLecTion.—Mr. J. W. Glass,
is exhibiting, at 1058 Broadway, Oakland, -a
large ‘and interesting collection of mineral,
botanical and fossilliferous specimens, and
Indian relics and .curiosities, which he has
collected mostlyin Arizona and New Mexico
and npon the great Colorado desert. There
are upwards of 2,000 hotanical specimens,
many of which are hoth new and interesting.
All are well preserved and mounted. There
are also some 8,000 mineral specimens and cutioeities. The collection is offered for sale,
entire, at a very small eum; with which, when
realized, Mr. Glass will again take the field for
further explorations. It would form a very
fine museum for an academy or scientific association, or for 1 private gentleman. An
opportunity ie here presented for some person
to immortalize his name, and encourage scientific exploration and investigation by making
thie collection a present to some public institution. The exhibition is free and well worth
a visit.

Potash Salt.
The mines from which this product is obtained are very valuahte, eince there ie no competition in the market. There are only two of
theee mines, one of which is in Germany, at
Leopoldshall and Stassfurt, and the other in
Austria at Kalusz. Mr. Knstel writes us from
Vienna, that a very oomplete exhibition of
everything connected with potash and its production, csn now be seen at the Vienna Exposition, He ssys, in referring to the mines
mentioned above, that it is the belief that tbeee
potash deposits are the result of the evapora.
tion of former remainders of large seas that
concentrated in a few favorable localities. The
formation of these deposits under euch pecuHar and Incky circumstances, indicates that
little prospect for new discoveries exist in this
line, but it is not impossible that such depoeites may be found in tbe United States, in districts where salt-rock is known to exist, Although the potash was known and ueed in
many branches of indnstry long ago, its large
aud extensive application in practical life is
not older than the diecovery of the Stasefurt
deposit (twelve or fifteen years ago). Formerly, tbe potash salt thet covered the salt-rock
bed was considered a nuisance; it was not
utilized; its value not known; and now, not tbe
immenee bed of salt-rock, but the above nuisance isconsidered the wealth of Stassfurt. Eight
millione of thalers were offered for that part of
the deposit which ie in Stasefurt, hut the offer
was not accepted. The total extraction of thie
salt in 1872, at Staesfurt and Leopoldehall was
elevefi millions of hundred weighte, This
sbows what extensive use is made of this article in agriculture and trade. The potaeh is
not free intho salt, but in several combinatione.
Ore Feeder for Shaft Furnaces.
Among the patents connected witb the mining
indnetry, recently obtained through the agency
connected with this office, is an ore-feeder for
shaft furnacee, invented by E. V. Standish, of
Belmont, Ney. The invention is an improved
device for feeding pulverized ore and salt into
upright or stack-furnaces. In this claes of fnrnaces the ore is first finely pulverized and then
dropped down through the furnace stack
with a certain proportion of salt, so that in ite
passage through the heat and flames the ore ie
roasted and chlorodized. This process of mixing and feeding the ore and salt into the top
of thefurnace requires to be accomplished repularly and thoroughly, and this invention is
intended for this purpoee.
Figure 1 of tbe accompanying cuts isa side
elevation showing a eection of one part of the
device and figure 2 isa plan view. A represents the top or upper end of a stack-furnace.
Upon this stack is constructed a shallow hopper, B, the opening through the bottom of
which is almost if not quite as large as the
upper end of the etack. The capacity and
ehape of this hopper can be varied to -suit the
different fnrnacee upon which it may be placed.
The bottom of the hopper ie constructed of a
nnmber of sqnare metal bars, ¢ ¢ c, placed
parallel with eacb other, and supported in
place by means of journals at botb ends which
bear on the oppoeite sidee of the hottom of the
hopper. ‘These bars may be made im a veriety
of shapes, but the inventor prefers the equare
or diamond shape. The bars are placed so

ite,’’ consisting of chlorpotsseium and chlormsgnesium, Then there are light, yellow
specimene of ‘‘ Cainite”; it contains eulphate
of potasss,magnesiaand cblormagnesium. This
will probahly he the more valuable mineral for
its sulphate of potassa. Another, but less frequent mineral, is the ‘‘Sylviue’’ of pure chlorpotassium, and the ‘‘Borasite,’’ containing
principally borate of magneeia, of which the
produced Jarge borax-crystals are also exhibited.
The existence of the potash in the ealt-rock
deposits of Kalusz was found in the year
1867; first in shape uf eylvine, then appeared
the cainite, and lately also the carnallite in
small quantities. Contrary to the appearance
in Stassfurt, the more valuable mineral predominatee in Kaluez. The sylvine is, as before mentioned, composed principally of pure
chlorpotassium, whicb is extracted hy simple
leaching, and, of course, is ohtained free of
chlormaguesium, which is difficult to accomplish at Stasefurt, even after several re-cryetallizatione. In larger proportion than the
sylvine, is found at Kalnsz the cainite, producing sulphate of potash aud chlormagnesium
hesides iron. Thie mineral, on account of its
amount of sulphate of potash, is more valuahle than either of sylvine or carnallite. The
specimens exhihited (from Kalusz) are massive blocks of several dozen each. The carnallite runs in parallel, yellow-brown stripes. The
cainite is grayish-yellow. The eylvine appears
in red and white varieties, mixed up with hlue
salt-rock,
Crry Crezx Canon.—A dispatch from Utah
says: Much interestis felt in the discovery of
a rich galeua lead, in City Creek Cation, seven
miles from Salt Lake City and 500 feet from
the new iron mine location. No mineral discoveries of moment have heretofore heen found
in these hills which hound the town on tbe
north. This fact causea the unusual feeling
that prevaila over thia location, and prospecting is lively; the proximity to the city is a ma.

ORE FEEDER.
‘borizontal plane, the angles of the adjoining
bars being jnst close enough together to pass
each other when tbe bars are rotated.
When the hars are in this position it is evident that the floor of the hopper will he formed
of a series of V ehaped channels, so that when
they are given a semi-rotary movement, tbe
pulverized ore and salt will be fed through between tbe shifting angles of the bars, first in
one direction and then in another, according
to which angle ie lowermost. The journale
which support one end of these bars paes
through the eide of the bopper, and have each
a vertically attached crank, f, secured to it,
while the arms at the opposite end of the
cranks are journalled in a horizontal har, G,
so that hy moving the bar, @, back and forth,
the cranks, f, are all moved simultaneously,
and the series of parallel bars, ccc, given an
oscillating or semi-rotary motion.
Tn order to give this bara reciprocating motion, its extremity is connected by a pitman,
J, with an ordinary crank motion from the
crank wheel, J, on tbe ahaft, M. The crankwrist of the crank wheel moves in a dove-tail
groove, 0, in the face of the wheel, so that it
can be shifted to or from the center as desired,
and fixed in place hy a set ecrew, r, to give
greater or lesa motion to the cranks, f, and
bars, cc.
The pulverized ore and salt in the proper
proportions are placed in the hopper, 8, and
the motion given hy suitahle power to the
shaft, 1, hy which the bara, cc, are caused to
make a partial revolution hack and forth, thus
feeding tbe ore and aalt through in a nniform
manner.

Agricultural and Mining Lands.
A diepatch, dated Washington, June 18, says:
Private inquiries having been made of the Attorney-General on the following subject, the
question was referred by him to the General
Land Office, and Acting Commissioner Curtis
to-day makes this statement as a rule of the
Department: On lands that have been entered
or patented ae agricultural lands, upon which
valnahle mines were known to exiet at the date
of snch entry, parties owning such mines are
in no way deharred from acquiring title thereto
upon compliance with the laws and inetrnctions
regulating the disposal of mineral lands, ae, by
express provisions of the laws, no title can be
acquired to mineral lands nnder the Acts regulating the dieposal of agricultural lands.In
all cases where lande have been returned ag
mineral upon the township plot, or where affidavits are filed witb local laud/officers, alleging that the lands are more valnable for mining
than for agricultural pnrposes, it is the duty
of the Register and Recorder to cause a hearing to determine their true character, before
allowing their entry under tbe pre-emption
and homestead laws.
Academy of Seiences.
At the last regular eemi-monthly meeting of
the CaHfornia Academy of Sciences, held on
Monday evening, Mesers. Geo. W. Lewis,
Agapius Honcharenko, Cutler McAllister, and
John R. Jarboe were elected resident membere
and Wm. C. Ralston a life memher,
The following additions to the cabinets were
received: Specimen of gorgonia, ohtained at Cerros Island; also skull of species of fish related
to the Rays, both presented hy Captain J. A.
Wilson, of San Pedro; skull of the mountain
sheep, Ovis Montana, with immense horns, presented by E. Waeeerman; two curious specimens of crustacea, from San Francisco Bay,
presented by. Henry Chapman,
Judge 8. C. Hastings read a paper on the
eation of frost on vines, which will he communicated to the Wine Growers’ Association.
Mr. A. W. Chaee read a very interesting paper on Artesian Welle in Los Angeles Connty,
which we will take an early opportunity of
publishing with accompanying diagrame.
Copies of the Proceedings of the Academy
for 1873 were distrihuted to the members. It
is quite a creditahle production for so short a
time coneiderintg the few contributing members. It containe about 96 pages and completes the proceedings up to May. The pamphlet contains eeveral platee and the snbjects
treated are all of Pacific Coaet interest.
TREATING THE ORES or _Meroury.—A correspondent calle attention to tbe letter of Mr.
Kustel, in our last issue, on the Patera process
for the treatment of the ores of mercury. He
thinke Patera is making poor progress in his
improvemente in that direction, when viewed
from a California standpoint. He very properly considers a loss of from 30 to 50 per cent.,
as set down for the Idria mines, as-a most
wasteful practice, and notwithstanding the
great reduction in sucb loss effected hy Patera
~from 30 or 50 per cent. to 16—the average of
loee still remeins far greater by thieimproved
method than the most waeteful process employed in this State.
The loes at Almaden is not above 5 or 6 per
cent.; while tbe Coalt & Roach, and the Knox
& Osborne and other proceeses claim to
work within one per cent. of assay value;
and where wood can be obtained at $5 per
cord, at a cost of only $1.25 per ton for ordinarily selected rock, simply reduced to what
may be called a large egg size; the great cost of
crushing, stamping and concentrating is saved
hy the latter proceee. We have written to our
Vieuna correspoudent for a full description of
tbe Patera procees, which will be placed before
our readers as soon as received.
A Curan-Up (partial) of the Spring Valley
Canal and Mining Company at Cherokee Flat,
of aninety-days’ run, resulted in $50,000 being
taken up. Their new Canal ie nearly finisbed,
but the pipe across Feather river is somewhat
delayed. One “chief” and a 5-inch nozzle
only was used, nor was all the flume cleaned,
Cuerry CREEK miuea, 75 miles from Eureka,
which were discovered last Septemher, turn out
some very rich gold ore. Capital is wanted to
erect reduction works; and no ore hae as yet
been worked.
Imports of silver ore into Liverpool during
May amounted to 1,520 tons and of silver lead
ores 380 tona.
