rich was the first successful
machine of the Taube class ever built.

INTERESTING MACHINES, 1910.--The Werner monoplane with E.N.V. engine,
combined shaft and chain drive, was a variant of the de Pischoff. The
Macfie biplane was a conventional biplane with 50 h.p. Gnome and useful
originalities. The Valkyrie monoplane, another British machine, was a
"canard" monoplane with propeller behind the pilot and in front of main
plane. The Weiss monoplane was a good British effort at inherent
stability. The Tellier monoplane was a modified Bleriot with Antoinette
proportions. The Howard Wright biplane was a pusher with large lifting
monoplane tail. The Dunne biplane was another British attempt at
inherent stability. The Jezzi biplane was an amateur built
twin-propeller.

SOME INTERESTING MACHINES, 1911.--The Compton-Paterson biplane was very
similar to the early Curtiss pusher; it had a 50 h.p. Gnome. The Sloan
bicurve was a French attempt at inherent stability with 50 h.p. Gnome
and tractor screw. The Paulhan biplane was an attempt at a machine for
military purposes to fold up readily for transport. The Sanders was
a British biplane intended for rough service. The Barnwell monoplane
was the first Scottish machine to fly; it had a horizontally opposed
Scottish engine. The Harlan monoplane was an early German effort; note
position of petrol tank.

The Clement-Bayard monoplane, 1911, was convertible into a tractor
biplane. The standard engine was a 50 h.p. Gnome. The machine was
interesting, but never did much. The Zodiac was one of the earliest
to employ staggered wings. With 50 h.p. Gnome engine it was badly
underpowered, so never did itself justice. The Jezzi tractor biplane,
1911, was a development of an earlier model built entirely by Mr. Jezzi,
an amateur constructor. With a low-powered J.A.P. engine it developed
an amazing turn of speed, and it may be regarded as a forerunner of the
scout type and the properly streamlined aeroplane. The Paulhan-Tatin
monoplane, 1911, was a brilliant attempt at high speed for low power;
it presented certain advantages as a scout. A 50 h.p. Gnome, fitted
behind the pilot's seat in the streamlined fuselage, was cooled through
louvres. The propeller at the end of the tail was connected with the
engine by a flexible coupling. This machine was, in its day, the fastest
for its power in the world, d
