IMPORTANT DIscovEny-LARp RENDERED. FLUID
DIT MxINo WITH RosIH.r-Professor Olmstead, of
New Haven, has lately made the important dis
covery, that, by adding one pound Of powdered
rosn TO three pounds Of lard, well stirred together,
the mass becomes semi-fuid at 72o F., and on be-
ing melted, which it does at 800, Notwithstanding
II melted alone the rosin requires 5000 and the lard
9Io OF heat, the compound will remain transparent
ana ilmpid at that temperature. As cools, pei
lIcle begins to form on the surface at 67oi and at
Ibo It remains dense semi-huid.
The discovery of the above named fact will be
OF great importance to those who use lard lamps,
as the lard is rendered more fluid by the rosn,
and the power of illumination increased two
hfths; yet, after two hours burning, II loses its
briIliancy on account or the wick becoming
clogged. This will not be an important objection
in families while in point Of economy the gain will
be considerable; for lard is worth three or four
times much as rosin. n.w H."- b 49,. ri
To machinists, the discovery is very import
ant, as it enables them to make of lard instead
of OIL which is not only saving in cost, but what
is of far more Importance the addition of the rosn
completely neutralizes the quality of acidity in the
lard, which corrodes metals, particularly brass
and copper, to such degree II is unfit to apply to
any thing not in constant use. Professor Ohm
stead says, thin coating of the compound laid
upon CRATE or sheet iron stove with brush, us
thin as possible will keep it free from rust all sum
mer, although stored in a damp place. r3 ana q,
To soap makers, the discovery is also import
ant. II one pound of the compound is added to
two pounds OF common Windsor soap, the quality
is greatly improved, and the tendency that soap
has to grow rancid, when in use, or kept moist
is thus entirely prevented A shaving cream Of
an excellent quality, may be made by taking a
cake Of good shaving soap and steaming 1t soft in
a close cup, and mixing half its weight of the
compound, and working it well together, adding a
little oil of almonds, or any other agreeable favor.
The same compound applied to boots and shoes
renders them nearly impervlous to water, and II
applied to the soles, will not soil the floor. The
uppers will be soft and plable, and not prevented
from receiving backing polish
For oiling carriages, the mixture OF lard and
rosin will be valuable; and when wanted for heavy
wheels, proper consistency may be given to II
by adding wheat flour, or, if greatly preferred,
black lead. ., g. O........... - ..'... ~.
No doubt the soap paste above described would
be a good fabrication for carriage wheels. We
hope this discovery will increase the consumption
of lard, and thereby give an improved market to
the farmer, and thus enable him to turn land into
lard, and lard into light, and in the meantime
lghten his mind and improve his condition.
New York Day GooDs MARKET FoR THE
WEEK ENDING FRIDAY, NOVEMBER 6.-Domestic
Goods.-The election has interfered with the opln-
ions Of trade. Brolun Sheetings and Shi, fings.-
All heavy brown sheetings and shirtings, which
were selling three weeks ago, are now selling mod
erately at about lc advance upon rates then OBJ
tanned; and portion of the styles then considered
little above the market, will now bring the price
at which they previously dragged. A large por-
ton of heavy goods are held ut &c higher, and
many sly les are Withdrawn from market. Bleached
sheetings and shirtings show no important ad-
vance. 1t is only those which were considered
cheap at old prices which are now selling at &c
higher. Printing Cloths.-Sales have not been
large, owing TO the increased price demanded by
a majority Of holders. The printers must soon
buy, but there is large assortment offering, and
it Is still question what course the market will
take. A large number Of mills have stopped; but
if the current rates are to be maintained, the con-
sumption must also decrease, although probably
not in great a ratio. There is u surplus now
on hand, sufficient, with the production which at
any rate will be continued, to supply all regular
demands this side of the LIST Of January. We no.
tce sales of 5000 pieces 60x6i % inches at &c
| 300 do 46x56 do at 4S-2, 900 do 56x56 49, do,
extra heavy, at $4,000 do 46x52 do at 4sc.
Prints-Low priced goods of every sort are in
quired for and prices generally are well main
tanned. Ciohs.-The downward tendency in the
lower grades has been arrested. The surplus Of
goods below 81 IS is smaller than last year, and
holders of regular styles now refuse to sell below
the average Of fall prices. Mixed and drab beav-
ers are now much inquired for, and the latter are
selling freely at good prices. Some few heavy
blues and blacks have also been taken. Foreign
Goods.-rhe principal business for several weeks
has been at auction, but the public sales nearly
over for the season. Our receipts Of spring goods
are yet comparatively light.-Jour. Com.
