** The Making of Freak Photographs [440]

An experiment that is interesting and one that can be varied at
the pleasure of the operator, is the taking of his own picture.
The effect secured, as shown in the accompanying sketch,
reproduced in pen and ink from a photograph, is that made by the
photographer himself. At first it seems impossible to secure such
a picture, but when told that a mirror was used the process is
then known to be a simple one.

The mirror is set in such a way as to allow the camera and
operator, when standing directly in front of it, to be

in a rather strong light. The camera is focused, shutter set and
plate holder made ready. The focusing cloth is thrown over your
head, the position taken as shown, and the exposure made by the
pressure of the teeth on the bulb while held between them.

** Hand Car Made of Pipe and Fittings [440]

Although apparently complicated, the construction of the miniature
hand car shown in the accompanying

[Illustration: Boy's Hand Car]

illustration is very simple. With a few exceptions all the parts
are short lengths of pipe and common tees, elbows and nipples.

The wheels were manufactured for use on a baby carriage. The
sprocket wheel and chain were taken from a discarded bicycle,
which was also drawn upon for the cork handle used on the steering
lever. The floor is made of 1-in. white pine, 14 in. wide and 48
in. long, to which are bolted ordinary flanges to hold the framing
and the, propelling and steering apparatus together. The axles
were made from 3/8 in. shafting. The fifth wheel consists of two
small flanges working on the face surfaces. These flanges and the
auxiliary steering rod are connected to the axles by means of
holes stamped in the piece of sheet iron which encases the axle.
The sheet iron was first properly stamped and then bent around the
axle. The levers for propelling and steering the car work in
fulcrums made for use in lever valves. The turned wooden handles
by which these levers are operated were inserted through holes
drilled in the connecting tees. The working joint for the steering
and hand levers consists of a 1/2 by 3/8 by 3/8 in. tee, a 1/2 by
3/8 in. cross and a piece of rod threaded on both ends and screwed
into the tee. The cross is reamed and, with the rod, forms a
bearing.

The operation of this little hand car is very similar in principle
