EXPERIMENTATION

Steep the end to be set in the
ground in a solution of blue vitriol,
one pound Of vitriol to forty of wa
ter. This is said to render the post
almost in~destructible 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 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 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 a certain result.
BLAcKING.-The lustrious 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 It's cheapness and accessibility {:
Three or four pounds vegetable
black, It pounds ivory black, 5
pounds molasses, and five pounds
glycerin, mixed thoroughly togeth-
er. Six ounces gutta perchs, cut in
small pieces, are then melted, and
when fluid, 20 ounces oliAe oil are
added, and s~ubquently, 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 its quantity of warm
water.
AMMONIA AS A CURE FOR SNAKE
BITEs-We recently called atten-
ton to the fact that as many as s,
900 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 939 cases in
which ammonia was freely admin
istered, 1902 victims have recovered,
and in the cured instances, the rem
edy was not administered till about
81 hours after the attack, on the az
erage. In the fatal cases the CORES
ponding duration Of time was At
hours.
MEASURING HEAT.-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 on the princi-
pie that the resistance of pure me-
tails to the electric current increas-
es with the temperature in a very sim
pie ratio. A platinum wire of
resistance is coiled around q
cylinder Of fine clay, and covered
with o tube of the same material.
The tube is connected with a
Daniels battery of two cells
with a resistance measure,
and placed in the furnace whose
temperature is to be ascertained.
It is then neozooary TO read on Tie
Indications of temperature Of
he graduated resistance. measurer.
The utility of such an instrument
obvious.
Projecting RooFs FROM FIRE
The Fireman's Journal, which ought
o be good authority on such mat
ers, says A wash composed of
ime, salt and fine sand or woodash-
s, put on in the ordinary way Of
vhitewash, is said to render shin

alling cinders in the vicinity. 1t
'ays the expence a hundred fold it is

ect of the weather. The older and
lore weather-beaten the shingles, {
be more benefit derived. Shin t

'srped, rough and cracked. The

How TO Stop BLEEDING AT THE .
.osE.-It is worth while to know .
ow to stop bleeding from the nose :
hen it becomes excessive. If the ,
lger is pressed firmly upon the 9
tile artery which supplies the .
God to the side of the face affected g
result is accomplished. Two
nall arteries, branching up from A
main arteries on each side of the Il
Eek, and passing over the outside
the jaw-bone, supply the face
tn blood. If the nose bleeds from
right nostril, for example pass
