the means of transportation on land are arriving
at points where the developments are swift and
remarkable, the space above the earth has not yet
been conquered, but is going through that same
period of development which precedes the production
of the true form itself.

MECHANISM DEVOID OF INTELLIGENCE.--The great
error, however, in seeking to copy nature's form
in a flying machine is, that we cannot invest the
mechanism with that which the bird has, namely,
a guiding intelligence to direct it instinctively, as
the flying creature does.

A MACHINE MUST HAVE A SUBSTITUTE FOR INTELLIGENCE.
--Such being the case it must be endowed
with something which is a substitute. A
bird is a supple, pliant organism; a machine is a
rigid structure. One is capable of being directed
by a mind which is a part of the thing itself; while
the other must depend on an intelligence which is
separate from it, and not responsive in feeling or
movement.

For the foregoing reasons success can never
be attained until some structural form is devised
which will consider the flying machine independently
of the prototypes pointed out as the correct
things to follow. It does not, necessarily, have to
be unlike the bird form, but we do know that the
