Each
aeroplane is fastened with a small thread from the point A as
shown. A figure of an airman can be pasted to each aeroplane. One
or more of the aeroplanes can be fastened in the blast of an
electric fan and kept in flight the same as a kite. The fan can be
concealed to make the display more real. When making the display,
have the background of such

a color as to conceal the small threads holding the aeroplanes.

** How to Make a Flint Arrowhead [23]
If you live where flints abound, possess the requisite patience
and the knack of making things, you can, with the crudest of tools
and a little practice, chip out as good arrowheads as any painted
savage that ever drew a bow.
Select a piece of straight-grained flint as near the desired shape
as possible. It may be both longer and wider than the finished
arrow but it should not be any thicker. The side, edge and end
views of a suitable fragment are shown in Fig. 1. Hold the piece
with one edge or end resting on a block of wood and strike the
upper edge lightly with a hammer, a small boulder or anything that
comes handy until the piece assumes the shape shown in Fig.
