To PRESERVE PosTs FROM RoT.-
Steep the end to be set in the
ground in q solution Of blue v~itriol,
one pound OF vitriol to forty OF wa.
ter. This is said to render the post
almost indcstructible by rot.
COATING SHEET IRON WITH ZINC.
The most recent method is by
passing the sheets of iron through
molten zinc, again through the
same hux, then through smoothing
roofs, and finally impinging there
on a current OF cold air as it rises
from the bath.
To DESTROY SrUMPs.--Bore with
a two.inch augur to the heart or
centre. Fill the cavity thus made
with Sulphuric acid or with crude
petroleum. In the first the acid de-
stroys it in a few months. In the
latter, when the stump becomes sat
urated with the oil, it is fired and
will burn to the roots. More than
one hole in the stump, and filled
with petroleum, will hasten the
time and secure u certain result.
BLAcKING.--The lu~strious quail
ties of backing are frequently de-
rived from ingredients which are
most deleterious and destructive to
leather. Herr Artus publishes a
new formula, and claims several adj
vantages for it to which we may
add its cheapness and accessibility /:
TIN ee or four pounds vegetable
black, II pounds ivory black, 5
pounds molasses, and five pounds
%glycerin, mixed thoroughly togeth-
er. Six ounces gutta rercha, cut in
small pieces, are then melted, and
when fluid, 20 ounces oliAe oil Are
added, and s~ubquently, 2 ounces
stearine. The second mixtur',
while quite hot, is stirred into the
first and then q further addition OF
10 ounces gum Senegal, dissolved in
about 3 quarts water is added
This compound is the stock for use,
it should be diluted with about
three times its quantity of warm
water.
MEASURING HEAr.-An instru-
ment has been invented in Ger
many which will measure with per
feet accuracy the heat of the hottest
furnace. 1t is based Oh the princi-
pie that the resistance of pure me-
tails to the electric current increas-
es with the temperature in Il very sim
pie ratio. A platinum wire OF
known resistance is coiled around a
cylinder of fine clay, and covered
with q tube of the same material.
The tube is connected with a
Daniels battery Of two cells
and with n resistance measure,
and placed in the furnace whose
temperature is to be ascertained.
1t is then necessary to read off the
indications of temperature OF
the graduated resistance measurer.
The utility Of such an instrument
is obvious.
PRoTEcTINGsRooFs FROM Fire
The Fireman's Journal, which ought
to be good authority on such mat
tiers, says: A wash composed of
lime, salt and fine sand Or woodash-
es, put on in the ordinary way Of
whitewash, is said to render shin
giles fifty old against taking fire from
falling cinders in the vicinity. 1t
pays the expence hundred fold it is
preserving influence against the e.
feet Of the weather. The older and
more weather beaten the shingles,
the more benefit derived. Shin
giles are generally more or less
warped, rough and cracked. The
application of wash, by wetting the
upper surface, restored them to
their original or first form, there
by closing the spaces between the
shingles ; and then lime and sand,
by filling up the cracks, prevents It's
varying.
How TO Stop BLEEDING AT THE
NosE. 1t is worth while to know
how to stop bleeding from the nose
when it becomes excessive. If the
is pres. ed firmly upon the
little artery which supplies the
blood to the side of the face affected
result is accomplished. Two
small arteries, branching up from
he main arteries on each side of the
leck, and passing over the outside
the jaw-bone, supply the face
Win blood. If the nose bleeds from
he right nostril, for example pass
he finger along the edge of the
light jaw till the beating of the ar +:
cry is felt. Press hard upon it, i
nd the bleeding will cease Con- 3
niue the pressure five minutes, I'M $
