RECENT INVENTIONS.
New Uses For Prar.—Mr. T. G. Ghislin
of Hutton Garden, England, has recently
invented a process for so treating the universal article of ordinary peat, hy chemical
and mechanical operations, as to bring it
intoa state in which it may be mannfactured
into various useful articles, cither of a solid,
rigid, or of a flexible character. This proeesstis described in the London Miniug
Journal, as follows :
He takes any of the common kinds of
peat, and having expelled therefrom, either
bythe application of pressnre, heat or otherwise, such of the watery particles as can be
easily removed, he mixes with it ground or
comminuted seaweed, with the addition, if
required, of any suitable gums or gum
resins, such as India rubber, gutta percha,
or other substances of that class, or in place
thereof, or in addition thereto, may he added
resins natural or artificial, bituminous substances and products of the same, such as
piteh or asphalte, paraftin, stearine, or other
oily and fatty matters. To givea body and
firmness to the mass, chalk, tale, sulphur,
sillicious, and other earthy matters may be
added. Waste fihrous and woody suhstances may be incorporated with the other
ingredients whenitis desired to form sheets,
of the material as for floorcloths, and if the
surface is intended to be printed metallic
oxyds, snch as white zine, oxyd of iron, or
ochre, alnm, and other analogous ingredients may be added. ‘The proportions in
which the several ingredients are incorporated with the peat mustdepend mainly upon
the character of the peat and the purpose
to which the mass of prepared peat is to be
applied when made; for instance, some
peats will be found to contain so much
unctuous, fatty or bituminous matter, and
some seaweeds so much mucilagimous or
gelatinous matter, that tho addition of more
bituminous or gelatinous matter will be unuecessary. On the other hand, the peat
and seaweed may want fiber to give it
strength and tenacity ; waste fibrons stbstances, such as cotton, hair, wool, and tow
may be incorporated in such cases. Inother
eases the peat will he found abundant in
fiber, but deficient in adhesive substances.
Again, for some purpose hardness and
rigidity will be required, as for monldiug
picture frames, or producing articles which
are to be ornamented by emhossing, such as
hook covers. For flooreloths and other
coverings or articles for which the mass is
to he rolled ont into thin infiexible sheets,
a larger proportion of fiber will be required
than for solid and rigid articles,

The Use of Tron Sponge for the Reduction
of Metallic Sulphides, Phosphides, Antimonides, Etc,
BY EDWARD PIQUE.
Mrssrs. Enrrors.—In several numbers of
your valuable paper have appeared items on
the ahove process, and in reading them I
have imagined that the operators certainly
went a considerably round-about way in this
matter. They take first an iron ore, which
contains the irou as oxyd, and veduce it to a
spongy metallic state. This is one operation which requires labor, fuel, etc. Then
they mix this iron sponge with the sulphurets, etc., and put it in the furnace agaiu,
which makes the second operation. Here
are consequently two operations, each of
them requiring labor, fuel, ete., where one
operation would have been quite snflicient,
and even a great deal better.
The matter is simply this : In the first operation they deprive the oxyd of iron of the
oxygen it coutains, by treating it with substances which, under the existing circumstances, possess a greater affinity for oxygen
than the irou does. These substances are
carbon, hydrogen, carbureted hydrogen,
protoxyd of carbon, and snch like. Nov, if
we consider the sulphur itself to be 2 comhustible suhstance, equal in its actiou to the
ahove mentioned, why not mix the oxyd of
iron or the iron ore immediately with the
sulphnrets to be desulphnvized, and make
one operation instead of two? What does
chemistry say ahout this? There are a great
many metals which combine immediately
with sulphur, but should the same metals,
in the state of oxyds and mixed with sulphur,
he suhmitted to a certain degree of heat, a
part of the sulphur will first be employed in
combining with the oxygeu of the oxyd,
forming snlphurons acid, which escapes, and
then the remaining sulphur will conuect
with the metal in the same way as if no oxygen had been present.
This shows quite plainly not only thatthe
reduction of the irou ore to its metallic state
is labor and fuel thrown away, but noreover
that by employing the ore in its uatnral condition of oxyd, only abont HALF THE QUANTITY
would be required to obtain the same result,
since the oxygen of the oxyd is itself an
agent capable of depriving the sulphuret of
its sulphur.
The peroxyd of iron consists of one eqniv.
of iron+one and a half equiv. of oxygen,
340 Fe +150 O=490 Fe O 114 ; therefore 4900
peroxyd or iron contain 150 oxygen, which
will convert 150 sulphur into sulphurous
acid. The 340 iron will further consume 200
sulphur to form sulphide of iron. The conclusion -we arrive at, is that the same quantity of iron ore, which in its oxydized state
will combine with 350 parts of sulphur,
when deprived of its oxygen will only be able
to combino with 200 parts of sulphur; conseqnently nearly double the quantity of the
iron ore will be required when reduced to
metal, than when applied in its natural state.
In connection with this matter, I wish to
correct an error made by one of your correspondents in your issue of December 22d.
Among other sulphides to be desulphurized
by iron sponge, he mentions the sulphide c#
copper, and gives even the precise method
of proceeding in the matter. BuntIam sure
the Doctor uever tried it, as it is a fixed fact
that copper possesses a far greater affinity
for sulphur than iron does, and in ali the
processes of copper extraction, as long as
there is any sulphur present, it will certainly remain combined with the copper, uotwithstanding any qnantity of ivou may be
present, althongh the latter will prefer to
unite with the oxygen which may be offered
to it from different combinations,

MONEY MARKET.
There has been no materlal improvement in the demand
for money since our last relerence, although a falr amount
ol business paper continues to be offered. For mercantile
purposes the demand has been light for some tlme past, but
more aetlvity may be anticipated at an early day. For the
development of mining claims in tbe interlor lt Is thougbt
that large remittances will be required In the spring. A mueh
more vigorous prosecution of the mining Interests, both In
this State aud Nevada is contemplated the present year, and
the condition of the money market favors it. The current
rates in bank are 1@1 ¥ ct. per mouth, and In the open market transactlons are made at 14@13 ct.; in mortgage seeuritles 1 % et. per month is the rate.
The Savings and Loan Soeiety declared a dividend of 11 3
et. per annum out of their net earnings during the past slx
months. In the previous half year they divided 10 #3 ct. per
annum. The Son Franciseo Savings Unlon have declared a
dividend of 1 #8 et. per month on terms deposits, and 10 Pct.
per annnw on call deposits, out of their net reeclpts during
the last hall of 1866; during tho first half they disbursed the
game dividend.
The Import dutles paid at the Custom House in this eity,
during the year 1866 amounted to $7,155,913 75; Im 1865,
$6,604,413; in 1864, $6,970,156, and In 1863, $4,683,399.
CITY STOCKS.
During the past week Spring Valley Water Co. sold at $59
@60 50; Pacifle Insuranee Co. at $1G7@167 50; San Fronelsco Gas Co., $64 50; Cal. Steam Naylgation 647433 4 et.,
and Centrai Railroad (eity) at $40 per share. The twentyproving dally. No change is reported in the north mine, and
during the rainy and inclement weather of the past month
uelther mill nor mine sustalned any damage.
Crown Potnt increased in market value from $565 in Jan.
uary to $1,390 in the month of April, sold at $950 in May, and
$1,050 in June, dropped to $700 in July—during whieh month
the bullion returns were meagre and amounted to only about
$37,500—ralled to $925 in August, receded to $880 In September, and from that time improved to $1,200 in Neeember, and
dnrieg the past week sold at $1,300, The heavicst reecipts of
bulllon during the twelve months of 1866 were In Februury,
amounting t0'$155,461 63,and the lowestin July, as above
stated. Forthe year the yleld has been $1,273,503, from say
33,377 tons of ore; prevlonsly the mine produced $217,748 14,
making a total of $1,491,251 14. During the part year this
eompany declared six dividends, $50 per foot in Mareh, $80
in April, May and June respeetively, and $50 in November,
and the same amount in Neeember, aggregating $234,000.
Gould & Curry sold at $885 in January, reacbed the highest polnt during the year in February—31,060—steadily decllned to $450 in November, advaneed to $775, and brought
$625@620 during the past weck. Turing the fiseal year ending November 30th, 1866, the bulllon produet of thls company
amounted to $1,635,383 92, belng tho yleld of 58,163 tons of
ore. March produced the most of this sum, $174,096 46, and
July the least, $105,446 49. The bullion reeelved In Neeember was $103,427 14. This lessened yield is due to the necessary general repalrs required at the mill, obliging them to run
at half canacity during the greater part of the month. The
ore product of that month was about 2,350 tons, of which
1,850 tons were dellvered to the Gonld & Curry mill and 700
tons to custoin mills. Three dividends were paid In 18#6—In
January $50 per foot, in April 830, and in June $380—making
an ageregute disbursement of $252,000 to stockholders.
Chollar-Potos] Improved from $139 to $390, receded during
third installment of $10 on the South San F iseo Hojnestead Association will be delinquent on the 29th of thls month.
The Calitornla Home Insurance Co, decided to discontinue
their bnsiness at the elose ot 1866, and outstanding accounts
are placed iu C. J. Farran's hunds for settlement.
MINING SHARE MARKET.
In presenting n brief review of the minIng share market
for the past year, it may be remarked that at the close of
January most stoeks had galned considerable strengtb,
though the transaetlons of the Board for that month had
fallen off about $1,000,000 irom the sales in Deeember, 1865,
A better feeiing man! fested itself In February, and from that
tlye until the elose of April the volume of buslucss Increased, together with a very general rise In prices. The
month of May exhibited a deeline both in valucs and ageregate salcs, and throughout the montbs of June, Juiy and August, a marked degrec of Inactlvity and flatness controlled the
market, reaching the greatest depresston In the tast named
month. The lucreased productiveness of the varlous prominent Comstock elaims at the beginning of September again
renewed confidence among dealers and lully revived the
buoyaney noted In the spring; however, prices were not 50
well malntained during the closlIng months o1 the year, with
several notable exeeptlons, as they had been some eight
months previously. The very favorable condition of most
leading mines for several months past, and the very flattcring appearance of the Comsteek veln at present depths, gives
erent assuraneé of future prosperlty. Tbe unproduetiveness
of deep mining is an exploded Idea, and a more united Interest is now galnlug gronnd among companies to assist in the
speedy inauguration as well as completion of the great work
known as the Sutro Tunnel.
From a carefully complied reeord of the sales In the San
Francisco Stock and Exchange Board we glve the followlng
very iuteresting tgures, extending over a period of three
years:

“NeEvaDA AND CoLorapo.”—Tho Reese
River Reveille has an article under the
above caption, in which it institutes a comparisou hetween the Smith & Parmelee
mine—which the ‘‘ Jonrnal boasts of as haying produced in one month, with seventyeight stamps, hnllion valued at $33,500, in
currency—and the Great Eastern, at Austin,
which has heen ridiculed as a ‘‘shoe-stving ”
mine. In the month of November, this
mine yielded bullion valued at upwards of
$50,000 in currency, employing twelve stamps
for twelve days. Talking into account the
difference in the cost of mining and reducing—said cost being about fifteen dollars
per ton in Colorado, and fifty dollars iu Austin—the profit on the Smith & Parmelee was
only $12,000 per month, while on the Great
Eastern it was over $29,000.
