the corners, tack them together with small nails, and
then put in a corner brace in the inside of each joint.
In doing this bear in mind that the material to be thus
fastened is light, and consequently the lightest of nails,
screws, bolts and corner pieces, etc., is necessary.



CHAPTER VIII.

THE REAL FLYING MACHINE.

We will now assume that you have become proficient
enough to warrant an attempt at the construction of a
real flying machine--one that will not only remain suspended
in the air at the will of the operator, but make
respectable progress in whatever direction he may desire to go.
The glider, it must be remembered, is not
steerable, except to a limited extent, and moves only in
one direction--against the wind. Besides this its power
of flotation--suspension in the air--is circumscribed.

Larger Surface Area Required.

The real flying machine is the glider enlarged, and
equipped with motor and propeller. The first thing to
do is to decide upon the size required. While a glider
of 20 foot spread is large enough to sustain a man it
could not under any possible conditions, be made to rise
with the weight of the motor, propeller and similar
