** Locking Several Drawers with One Lock [314]

A series or row of drawers can be secured with one lock by using
the

[Illustration: Drawer Lock]

device shown in the sketch. This method takes away several
dangling locks and the carrying of many keys. A rod is used
through the various staples over the hasps. The rod is upset on
one end and flattened to make sufficient metal for drilling a hole
large enough to insert the bar of a padlock. If the bar is made of
steel and hardened, it is almost impossible to cut it in two.

** Testing Small Electric Lamps [314]

The accompanying sketch shows the construction of a handy device
for testing miniature electric lights. The base is made to take in
an electric flash lamp battery. Two strips of brass, C and D, are
connected to the battery. The lamp is tested by

putting the metal end on the lower brass strip and the side
against the upper one. A great number of lamps can be tested in a
short time by means of this device.

** How to Make a Pin Ball [314]

The pin ball shown in the illustration is made of calfskin
modeling leather and saddler's felt. Two pieces of leather are
used, and one piece of felt, all three being cut circular to a
diameter of about 3 in. The felt may be about 1/2 in. thick, and
leather of a deep brown color is recommended.

Moisten the leather on the back side with as much water as it will
take without showing through the face. Lay it on a sheet of heavy
glass or copper, or other hard, smooth, nonabsorbent material.
Place the design, which has been previously prepared, over the
face of the leather. Indent the outline of the design with a
nutpick or any other pointed tool that will not cut the leather.
Remove the pattern, and go

over the outline again to deepen the tool marks.

The space between the border and the design is now stamped with a
cuppointed nail set, care being taken not to cut the leather,
especially if the tool be new. Rubbing the edges of the nail set
over a piece of emery paper will serve to dull them, if they are
too sharp.

When the designs have been worked on the leather, paste or g
