CHAPTER I.
EVOLUTION OF TWO-SURFACE FLYING MACHINE.
By Octave Chanute.
I am asked to set forth the development of the "two- surface" type of
flying machine which is now used with modifications by Wright Brothers,
Farman, [1]Delagrange, Herring and others.
[1] Now dead.
This type originated with Mr. F. H. Wenham, who patented it in
England in 1866 (No. 1571), taking out provisional papers only. In the
abridgment of British patent Aeronautical Specifications (1893) it is
described as follows:
"Two or more aeroplanes are arranged one above the other, and
support a framework or car containing the motive power. The aeroplanes
are made of silk or canvas stretched on a frame by wooden rods or steel
ribs. When manual power is employed the body is placed horizontally, and
oars or propellers are actuated by the arms or legs.
