TIE WORKSHOP.

If THE tips of nails be dipped in grease
they can easily be driven into hard wood
where otherwise they would double and
break.
PAINT buildings In cool, damp weather,
so that the oil VIII remain on the surface
and not be absorbed by the dry and
porous wood.
OmING 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 at 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 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 week or
more.
VARNIsH for writing on glass may be
made of 500 grains ether, thirty grains
sandarac, and thirty grains mastic.
Dissolve and add benzine until the var
nish imparts to glass q roughened APP
pearance. Use cold.
A TIGHT brick box, of 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 perfect filter. Bricks are
porous and water Will pass through
them as fast it can be pumped out.
\ NEW method of tempering steel has
been published by NJ. Clemandot.
The metals are heated to n 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 caleined and powdered fiints
were used, but now sand procured from
mines in various places Is used. To fit
it for use it is dried or burned, sifted and
washed Much fine sand is taken from
New Jersey to France.
THE best packing for faced joints,
either steam or water, Is common draw
/ ing-paper soaked In oil after a short
/ substance like parchment, so that it Is
| practically indestructible, and it has the
I advantage of stripping readily from sur
/ faces when it Is desired to break joint.
NJ. CoRNU holds that steel plates can
not at present and as a general rule be
/ depended upon in boiler-making More
( care Is required In their manipulation
/ than the most of manufacturers seem
! disposed to bestow and the more rapid
! corrosion of steel plates, taken In con-
nection with their thinnesE, increases the
+ risk of disaster.
/ IN MANUFACTURING paper OF wood,
J poplar, spruce, Eastwood and pine are
| used. Blocks Of wood are ground to
! pulp by pressing on two emery rollers,
I revolving in different directions. The
| wood pulp is used with twenty-five per
/ cent, or whereabouts, of other stock A
machine viii grind about ton of pulp a
day, with forty to sixty horsepower,
according to the wood ground. Half a
century ago a mill producing 1000
pounds of paper per day was considered
/ as doing an immense business, while
now there are 936 mills scattered
/ throughout the country, making 1000
| pounds to ten or twelve tons of paper
I each per day.
