New Qoantz Petynpumen—The Grags Valley Union says that Mr. P. Fox,an experienced
Cagineer and machinist, is eadeavoring to ivtroduce into the quarta mills of that place a
palvcriger, for which he has obtaincd a patent.
Tle states from what he has seen of quartz
tailings there, that his pulverizer is a sine qua
non in every mill, as it receives the ernshed
quartz from the battery, and then reduces it to
an inmpalpablo powder by incans of rotary
grinding etoncs. At the Ophir they havo
cylindrical grinders, which aru very good, bat
ho claims that hia grinders, being of stone, reduce the quartz to a finer state, and is also
anjuch quicker process. Ono pulverizer is
sulficicnt for five stamps. The expense is very
moderate, and tho machino is readily applied.
It is tbe arasta principle, but the action is
quicker and the quartz reduced finer. hero
is a great difference in the cost.
Tue Dhrvetesce.—The Stockton Jndepends
ent, alluding to tho comparative cost of mining
operations. in California and Nevada, says :
One great advantage in engaging in working
mines in this State, inpreferenco to mines
elsewhere, is the comparatively small cost of
mining and reducing ores in California. Compare California with Nevada, for instance : It
appears that it cost tho Chollar Potosi Company last year, ou au average, $22.27 per ton
to miuo and work its ores. In California tho
costol mining and reducing the ores ranges
from $4 to $8 per ton—$5.50 being abont the
averave. Thus, in this State, gold ore which
will yield $10 per ton will yicld a rousing profit,
while silver ore in Nevada paying $20 per ton
cannot be workcd except at a great loss. ‘Those
Seeking for mining investmenta should bear
these important facts in mind.
Sroncrs.—lt may surprise the reader to be
inforined that the quantity of sand he finds in
a new sponge has not been inclosed there, by
the animal or vegetable during its growth, but
*is an adulteration practised by the agents and
merchants who purchase the sponge from tbe
divers, in order to increase its weight and their
profit. Sand of the fineness requisite for the
purpose, is mixed with water, in which there is
a little gelatine or gum to ennble the sponges
to take up and retain it the better, aod without
being detected afterwards; the sponges are
then well kneaded into it, so as to Hill up their
minute pores and dried. Jn this way a hundred weight ol sponges in their dry state, will
be £0 sanded as to weigh more than a ton bet
‘fore they are packed for exportation to Europe.
Warer-Proor Exauru ror Carp ProrooraPus.—The following process for enameling
cards is very good substitute for the collo<dion transfer process, and is. much_easior of
application. first apply to the surface of tbe
card, with a brush, a solution of Zum arabic in
water, of sufficient strength to give consider,
able gloss when dry, As soon as dry apply a
coattog of plain collodion ip the same maaner
as couting a plate. If the solution is ‘not
very tough, two or three coatings may be
‘applicd to advantage. Finish by passing the
card through a roller and you will have a fine
gloss. Care must be taken not to have the
gum solution too thick, or the surface will
-erack when dry, though there is but little daagerif the collodion ig applied soon after the
gum isdry. Gelatin, instead of gum arabic,
answers the purpose well, though it gives
hardly as mnch’gloss. Perhaps you or your
teaders may bave a better process than this.
Tf so, let us have it— Philadelphia Photographer. ——
Varnyisit For Pootoorarus.—M. Busei first
brnsbes the prints over witb a solution of gum
arabic. and when this is dry, applies a coatiag
of collodion. The following are the proportions recommended: 1. Clear transpareat
‘gnm arabic, twenty-five grammes; distilled
water, 100 cub. cents.; dissolve and strain.
2. Gon cotton, three grammes; alcohol, sixty
grammes ; ether, fifty grammes, By thisdonbla
