GLOSSARY



INTRODUCTORY

In preparing this volume on Flying Machines
the aim has been to present the subject in such a
manner as will appeal to boys, or beginners, in
this field of human activity.

The art of aviation is in a most primitive state.
So many curious theories have been brought out
that, while they furnish food for thought, do not,
in any way, advance or improve the structure of
the machine itself, nor are they of any service
in teaching the novice how to fly.

The author considers it of far more importance
to teach right principles, and correct reasoning
than to furnish complete diagrams of the details
of a machine. The former teach the art, whereas
the latter merely point out the mechanical
arrangements, independently of the reasons for
making the structures in that particular way.

Relating the history of an art, while it may be
interesting reading, does not even lay the foundations
of a knowledge of the subject, hence that
field has been left to others.
