clined to give forward push, move
in opposite directions and are Searel
through the cylinder, SO that they
make an equal number Of revolutions,
The wings do not SO round AT an even
speed. but have beat like that OF a
birds wing. Tho circle they describe
is divided into two parts, one-Quartcr
and three-Quarters, the smaller one
being directly above the center, The
down stroke is the driving one and Is
given with three times the speed ot
the return. That is, the wing on the
left travels the whole of the lower arc
while the one on the right moves oNHr

recty through the center of the engine
and at the oluer side are attached 10

two wings in the three-and-ouc rolg-
ton, both MS 10 position and spec |,
controlling on same shafts the stroke
of the engine. The engine has two rts-

der but revolve in It, both round the
same center. Speed is CONT oiled by

There is no need for brake, tho re-

times a minute will rock his machine

DurHea motor carriage and the Bray

that. aside from even horseless car

however, that Mr.. Elargrave holds the
view that large aeroplanes with all
their complications of double skins,
elaborate staying and geometrical pro-
gression, arc now quite out Of the run

! the immediate future has its greatest
i dime nsion perpendicular, the lifting
surface being composed of II sufficient
number of small aeroplanes attached
to one wire, the head resistance and
supporting area only increasing in
arthmetical progression with the
weight to DO lifted.
