direct the air downward toward the rear and, as the air
is thus forced downward, there is more or less of an impact
which assists in propelling the aeroplane upwards.



CHAPTER VI.

LEARNING TO FLY.

Don't be too ambitious at the start. Go slow, and
avoid unnecessary risks. At its best there is an element
of danger in aviation which cannot be entirely eliminated, but it
may be greatly reduced and minimized by
the use of common sense.

Theoretically, the proper way to begin a glide is from
the top of an incline, facing against the wind, so that
the machine will soar until the attraction of gravitation
draws it gradually to the ground. This is the manner in
which experienced aviators operate, but it must be kept
in mind that these men are experts. They understand
air currents, know how to control the action and direction
of their machines by shifting the position of their
bodies, and by so doing avoid accidents which would be
unavoidable by a novice.

Begin on Level Ground.

Make your first flights on level ground, having a couple
