grease are left, apply powdered calcined magnesia.
Bone, well calcined and powdered, and plaster of Paris are also
excellent absorbents of grease.

A beautifully bound book, and quite new, had oil from a lamp
spilled over it. There was no quicklime to be had, so some bones
were quickly calcined, pulverized and applied. The next morning
there was no trace of oil, but only an odor which soon vanished.

** Tightening Cane in Furniture [230]

Split cane, used as part of furniture, such as chair seats, often
becomes loose and the threads of cane pull out. This can be
prevented by sponging with hot water, or by applying steaming
cloths to the cane. This process also tightens the shreds of cane
and does not injure ordinary furniture. If the article is highly
polished, care should be taken to prevent the hot water from
coming in contact with anything but the cane.

** Cleaner for a Stovepipe [230]

A long horizontal pipe for a stove soon fills with soot and must
be cleaned. The usual method is to beat the pipe after taking it
down to be cleaned, but a much better device for the purpose is
shown in the sketch.

A scrub brush is procured and cut in two, the parts being hinged
to a crosspiece fastened to a long broom handle. The brushes are
pressed outward

against the inside surfaces of the pipe with a wire and spring, as
shown.

** Mounting Photo Prints on Glass [231]

Photograph prints can be mounted on glass with an adhesive made by
soaking 1 oz. of sheet gelatine in cold water to saturation, then
dissolving in 3-1/2 oz. of boiling water. Let the solution cool to
about 110 deg. F., then immerse the print in it and squeegee, face
down, on a clear piece of glass. When dry, take a damp cloth or
soft sponge and wipe off any surplus gelatine on the glass.

** Dropping Coins in a Glass Full of Water [231]

Take a glass and fill it to the brim with water, taking care that
the surface of the water is raised a little above the edge of the
glass, but not running over. Place a number of nickels or dimes on
the table near the glass and ask your spectators how many coins
can be put into the water without making it overflow. No doubt the
reply will be that the water will run over before two coins are
dropped in. But it is possible to put in ten or twelve of them.
