extended pinions it rushes across the super

How It Looks Without Wings.
Without it's wings the airsh.p becomes
verify machine without any suggestion OF
capacity for flight. 1t is huge, though not
a misshapen collection of mechanical parts

which the Smithsonian experts have ex-
pended upon the aerodome Nowhere is this
so apparent as in the section amdships
There. within a small area, Is found the
most varied assortment Of mechanical de-
vices imaginable, and all arranged in exact
relation to each other and in conformity to
the general plan. Considerable room is
taken up here by the motor and it's appur-
chinery extending therefrom to the pro-
pellers and the steering gear.
The machine is something over sixty feet
from the end of the rudder to the tip of the
bowsprit From tip to tip of the wings the
distance is nearly fifty feet. AS it is equip
ped for flying, the aerodOme weighs /, 80
pounds. The shape of the central body is
elliptical. This is composed of three large
steel tubes. the outer two of which form
the contour. The third extends throughout
the length of the body in the center, a dis
tance of something like forty-five feet. The
supporting framework is, therefore, very
a frNYV ffA
SNAPPED body which was generally ascribed
to the aerodome.
Breadth at Bow and Stern.
About the stern and bow the breadth is in
excess of four feet Amidships, where the
principal machinery is located. the vessel
broadens out until the width is nearly
twelve feet. About equal distances from
the ends of the machine fore and aft are
bridges which suggest those of a marine
vessel These are for the attachment of the
wings.
The gasoline motor which is really Prof
Manly's principal contribution to the en-
tire equipment. is stationed we'll below the
principal surface. 1t is of the explosion
type, weighs 2CO pounds and generates
power, capable of being utilized in actual
flight. Long rods connect this with the
prope1lers. the blades of which are about
three feet long. With the engine working
lull DldSt tney are capable OF turning l,IU
or even more times per minute. This, pro-
vided the aeroplane is travelling in exact
horizontal flight, is calculated to give a
general velocity OF from forty to fifty miles
per hour. Near the motor is situated the
| navigator's car. Though broad 1t looks
something like a canoe and has a delicate
but substantial framework covered with
canvas The cabinet is so disposed that
the aerOnaut is in closest touch with his en-
gines. He is there in the best possible po-
Stion for guiding the machine well as
for noting the behavior of all the parts.
The car is constructed to carry a man
weighing as much as 15O pounds which is
the limit of avoirdupois for the navigator.
Device to Keep Machine Poised.
A device for keeping his machine poised in
the wind is situated down below the main
body. OF this there are two parts, both
made of canvas. The front is a rectangular
piece the long direction extending longitu-
dinally.
The apparatus is vertically disposed. SO
that it tends to keep the ship in the wind.
In this it acts something like the center
board OF sailing vessel The other appa-
ratus adjoining it consists of three PAL is.
One is straight and the other two diverge
at gradual angles. Working Oh hinges these
two are designed to have some bearing upon
the speed of the ship.
Five conical-shaped bodies equally dis
tributed about the vessel are to assist In

floats to keep the machine from sinking
when it strikes the surface of the river.
The wings. four in number, measure 2Ox10
feet. But they are 50 disposed with their
tent like shape that a much greater sus-
taining surface is secured. They are COW

delicate bars and are exceeding light as we'll

The steering gear is much like that of the
models. 1t is delicately constructed with
four canvas blades five feet long on strong
wooden framework. This Is adapted both
to horizontal and vertical steering.
