If THE tips Of nails be dippedi In grease
they a easily be driven into hard wood
where otherwise they would double and
break.
PAINT buildings in cool, damp weather,
so that the oil will remain on the surface
and not be absorbed by the dry and
porous wood.
OMINa shingles at the time Of laying
roofs is recommended by experts. Dip
ping in hot whitewash serves to pre-
serve shingles from decay.
WHEN buildings settle unevenly. let
them be levelled up ct once, as standing
on an uneven foundation strains every
part and breaks the nails and cracks the
walls.
The largest crucible steel casting ever
known was lately made at Sheffield Eng.
land: 1t wasa spur rim twenty-eight feet
in diameter, machine moulded, and was
cast whole total weight, ten tons.
WOOD piled in a tank and covered
with quicklime which is gradually
Stacked with water is said to ACQUIRE
great hardness and consistency after the
lime has acted upon it for a week or
more.
VARNIsH for writing on glass may be
made of 800 grains ether, thirty grains
sandarac, and thirty grains mastic.
Dissolve and add benzine until the var
nish imparts to glass a r~oughened ap.
pearance. Use cold.
A TIGHT brick box, of a capacity of
eight or ten quarts, built in the bottom
OF a ~cistern, enclosing the end of the
pump-pipe, cannot be exhausted, and
will act as a perfect filter. Bricks are
porous and water will pass through
them as fast as it can be pumped out.
A NEW method of tempering steel has
been published by NJ. Clemandot.
The metals are heated to a cherry red
and then compressed strongly until they
are cool. The result is great hardness
and an exceedingly fine grain. Steel
thus treated makes excellent permanent
magnets.
THE base of all glass is sand, and the
quality of this is of great Importance
Formerly calcined and powdered flint
were used, but now sand procured from
mines in various places Is used. To Fl
it for use it is dried or burned, sifted ani
washed. Much fine sand is taken from
New Jersey to France.

corrosion of steel plates, taken in con

risk of disaster.
In MANUFACTURING paper of wood
poplar, spruce, Eastwood and pine ar
used. Blocks of wood are ground t
pulp by pressing on two emery rollers
revolving in different directions. TIL
wood pulp is used with twenty-five pc
cent, or thereabouts, of other stock.
machine will grind about a ton of pulp
day, with forty to sixty horsepower
according to the wood ground. Half
century ago a mill producing LOO
pounds of paper per day was considers
as doing an immense business, Will
now there are 936 mills scattere'
throughout the country, making 100
pounds to ten or twelve tons of pape
each per day.
