TO MAKE NEW A CORRODED PEN.

When a pen has become so corroded as to be useless, it can be made good as
new by holding it in the flame of a gas jet for half a minute; then drop
in cold water, take out, wipe clean, and it will be ready for use again.

ENAMEL FOR FINE CARDS.

For the brilliant enamel now often generally applied to fine cards and
other purposes, the following formula is given:--For white and for all
pale and delicate shades, take twenty-four parts, by weight, of paraffine;
add thereto 100 parts of pure kaolin (China clay), very dry and reduced to
a fine powder. Before mixing with the kaolin, the paraffine must be heated
to fusing point. Let the mixture cool, and it will form a homogeneous
mass, which is to be reduced to powder, and worked into paste in a
paint-mill, with warm water. This is the enamel ready for application. It
can be tinted according to fancy.

ELECTROTYPING HANDWRITING.

To produce electrotypes or stereotypes of letters, signatures, ordinary
written matter, drawings or sketches, coat a smooth surface of glass or
metal with a smooth, thin layer of gelatine, and let it dry. Then write or
draw upon it with an ink containing chrome alum, allow it to dry exposed
to light, and immerse the plate in water. Those parts of the surface which
have not been written upon will swell up and form a relief plate, while
those parts which have been written upon with the chrome ink have become
insoluble in water, after exposure to light. The relief may be transferred
to plaster of Paris, and from this may be made a plate in type metal.

BLACK PAINT FOR BLACKBOARDS.

Take shellac varnish, one-half gallon; lampblack, five ounces; powdered
iron ore or emery in fine powder, three ounces. If too thick, thin down
with alcohol. Give the wood three coats of the composition, allowing each
to dry before putting on the next. The first coat may be of shellac and
lampblack alone.

TO CLEAN STEEL PENS.

Potato is used to clean steel pens, and generally act as a pen-wiper. It
removes all ink crust, and gives a peculiarly smooth flow to the ink. Pass
new pens two or three times through a gas flame, and then the ink will
flow freely.

STATIONERS' WINDOWS.

It is important that strangers should get a good impression with a tasty
window, or a polite reception when entering the store. Remember that first
impressions go a great way, and when once formed, good or bad,
