The aeroplane as an ad-
Sunct to military operations has al
ready shown it's value both in Tripoli
and in Turkey. Besides dropping
bombs upon Turks and Arabs it has
proved of greater usefulness in re-
connoitring the position OF the enemy.
The Bulgarians have gone a step fur-
theirs and have used the aeroplane Tor
fire control purposes, enabling the bat
tery commanders Of the field guns to
train their weapons so as to make
them tell most effectively against the
Sultan's forces. This matter OF hre
control is as vital to a navy as to an
army in action, especially when the
guns of a feet are searching out the
weak spots in the lane defences. But
heretofore the %aeroplane has been less
available for navy than for army use
The catapult tested in Washington
Is the invention of Captain Chambers
of the navy, and is the outcome OF va
rious lessons learned while trying to
adapt the aeroplane to the needs or
the navy. The ~practicability Of send
ing a~eroplanes in fight from q suit
able platform on board ship was
early demonstrated, but there were
various minor problems to be solved,
The launching platforms employed
were both long and cumbersome. They
took up space that would not be avail
able in time OF war, and they blocked
the fire of some Of the guns.
The long runway or sloping plat
form was therefore prohibitive. With
a short track substituted which could
be easily and quickly put In place
and just speedily demounted and
stored out of the way, there arose the
question of a means Of starting the
aeroplane effectively. For this pur-
pose Captain Chambers devised the
catapult. For years he had spe-
cialized in %torpedoes and was familiar
with the devices successfully tried
In getting those weapons overheard
from a boat. The catapult tried at
Annapolis last summer was a sort of
modified torpedo launching outfit OF
the earlier type, and compressed air
was employed to give the initial push.
The trial mechanism was of necessi-
ty rather crude, but this fact did not
deter Lieutenant Ellyson from sub
jecting himself In a hydroaeroplane
to the extreme shock Of the device In
order to find out the effects OF such
a conclusion, not only upon the air
pilot, but likewise upon the motor
attachments and other fittings when
might be wrenched loose or deranged
That test was entirely satisfactory IN
its lessons, but the aviator and his
machine got a %ducking.
The catapult lately tried at the
Washington nav yard is devised so
that the hydroaeroplane attains It's
launching speed without violence, and
this insures the launching of the ma
chine without fear Of d~eranging any
of the apparatus or d~islodging the
aviator from his seat. The runway
or starting track Is short and al be
put in position in several places on
a fighting ship without interfering
with the maneuvering Of the guns or
impeding any other operation Of Inn
pOrCance.
or course the demonstration at
Washington over the Potomac river
under fairly ideal weather conditions
is not a counterpart Of what may CON-
front the naval aviator at sea. but so
far as the actual getting away from
the ship is concerned that function
can be promised under n circum-
stances which on shore would warrant
an aviator in trying to go up In the
air. The other side OF the problem
IL that of returning to the ship again,
and here success Is likely.
Glenn H. Curtiss has devised a form
Of float or boat for his hydros which is
capable of sustaining the flying ma
chine when wave Of considerable size
