To PRESERVE PosTs FRoN Ron
Steep the end to be set In the
ground IN a solution of blue vitriol, /
one pound ofvitriol to forty of wa
ter. This is said to render the post
almost indestructible BY rot.
COATING SHEET IRON WITH ZIEc.
The most recent method is by
passing the sheets Of iron through
molten zinc, again through the
same fux, then through smoothing
roofs, and finally impinging there
on a current of cold air as it rises
from the bath.
To DESTROY STUMPs.-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 few months. In the
latter, when the stump becomes sat-
urated with the oil, it is fred and
will burn to the roots. More than
one hole in the stump, and filed
with petroleum, viii hasten the
time and secure certain result.
BLACKING.-The Iustrious 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 ad-
vantages for it to which we may
add its cheapness and accessibility
Three or four pounds vegetable
black, II pounds ivory black, 5
pounds molasses, and five pounds
glycerin, mixed thoroughly togeth-
er. Six ounces gutta percha, cut in
small pieces. are then melted, and
when fluid, 20 ounces oliAe oil are
added, and subquently, 2 ounces
stearine. The second mixture,
while quite hot, is stirred into the
first and then a 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 it's quantity of warm
water.
AMMONIA AS A CURE FOR SHAKE
B1rEs-We recently called atten-
ton to the fact that as many as 8,
600 persons die annually In British
India and Burmah, from the effects
of snake bites. The Inspector of
Police to the Bengal Government
now reports that of $50 cases IN
which ammonia was freely admin
istered, TOP victims have recovered,
and in the cured instances, the rem
edy was not administered till about
81 hours after the attack, on the aV-
erage. In the fatal cases the CORES
ponding duration of time was Al
hours.
MEASURING HEAT.-An instru-
ment has been invented In Ger
many which win measure with per
feet accuracy the heat of the hottest
furnace. It is based on the princi-
pie that the resistance of pure me-
tails to the electric current increas-
es with the temperature in q very sim
pie ratio. A platinum wire of
known resistance is coiled around a
cylinder of fine clay, and covered
with a tube of the same material.
The tube is connected with a
Daniels battery of two cells
and with q resistance measure,
and placed In the furnace whose
temperature is to be ascertained.
It is then necessary to read off the
indications of temperature of
the graduated resistance. measurer.
The utility of such an instrument
is obvious.
Projecting RooFs FROM FIRE
The Fireman's Journal, which ought
to be good authority on such mat
ters, says A wash composed Of
lime, salt and fine sand or woodssh-
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. It
pays the expence hundred fold it is
preserving influence against the eff
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 filing up the cracks, prevents It's
warping.
How TO SToP BLEEDING AT THE
NosE.-It is worth while to know
how to stop bleeding from the nose
when it becomes excessive. If the
finger is pressed firmly upon the
little artery which supplies the
blood to the side of the face affected
the result is accomplished. Two
small arteries, branching up from
the main arteries on each side of the
neck, and passing over the outside
of the jaw-bOne, supply the face
with blood. If the nose bleeds from
the right nostril, for example pass
the finger along the edge of the
right jaw TIL the beating of the az
terry is felt. Press hard upon it,
and the bleeding will cease. Con-
tinue the pressure five minutes, un-
til theruptured vessel in the nose
