l black.

In use, the device is set with the lens tube directed toward the
scene to be painted or sketched and the lens focused so the
reflected picture will be seen in sharp detail on the glass.
Select your colors and put them on the respective colors depicted
on the glass. If you wish to make a pencil drawing, all you have
to do is to fill in the lines in the picture on the ground glass.
If a plain glass is used, place tracing paper on its surface, and
the picture can be drawn as described.

** How to Make Miniature Electric Lamp Sockets [270]

A socket for a miniature lamp can be made as shown in the sketch.
A brass spring wire is wound around the base of the threads on the
lamp and an eye turned on each end to receive a screw and a
binding-post, as shown in Fig. 1. A piece of metal, preferably
copper, is attached to a wood base as shown in Fig. 2 and the
coil-spring socket fastened across it in the opposite direction.
Bend the wire so that the spring presses the lamp against the
metal. If the wire fits the lamp loosely, remove the lamp and
press the sides of the coil closer together. The metal parts can

be attached to any smooth surface of wood without making a regular
base.

** Imitation Arms and Armor-Part V [271]

The preceding chapters gave descriptions of making arms in
imitation of ancient weapons, and now the amateur armorer must
have some helmets to add to his collection. There is no limit to
the size of the helmet, and it may be made as a model or full
sized. In constructing helmets, a mass of clay of any kind that is
easily workable and fairly stiff, is necessary, says the English
Mechanic, London. It must be kept moist and well kneaded. A large

[Illustration: Making the Clay Model and Three Helmet Designs]

Board or several planks, joined closely together, on which to
place the clay, will be necessary. The size of this board will
depend on the size of the work that is intended to be modeled upon
it.

The way to make a helmet is described in the following method of
producing a German morion, shown in Fig. 1. This helmet has
fleur-de-lis in embossed work, and on each side is a badge of the
civic regiment of the city of Munich. The side view of the helmet
is shown in Fig. 1.

The clay, is put on the board and modeled into the shape shown in
Fig. 2. This is done with the aid of a pair of compasses, a fe
