our American military and naval avia-
ton training camps. Considering the
risks the novice necessarily takes and
the very special physiological and psy-
Geological factors that enter into the
science of flying, these fatal accidents
are few In proportion to the number
OF men undergoing training. and they
are not more numerous than those on
the training fields of Great Britain,
France and Italy,
A perfect knowledge of all the rules
of the game of flying will not save a
man who lacks confidence In himself
and is inclined to hesitate. A half
second Of indecision may be fatal In
itiative, the sporting instinct and a
certain responsibility, qualities In
herent in American youth. have been
found OF far greater value In the air
than the logical. scientific. severely
disciplined character of the Germans,
and account for ne superiority of the
allied aviators In general.
The most eminent Of British scien-
lists have devoted special study to the
psychological and physiological as
poets OF flying.
One authority says that good eye
sight. normal hearing. good muscle
sense" and equalization are indlspen-
sable qualifications. But most impor-
tant OF all Is the right temperament
not an easy thing for a medical board
to examine. OF the types-the imagi-
native and the unimaginatlve-the
imaginative youth Is said 10 make the
better pilot II he can keep his imagi-
nation under control.
Surgical Operations No Bar.
In the British air service previous
history of wounds and disease is thor
oughly investigated. Persistent head
aches, vertigo aud easily induced IA
tigue are serious defects. But some
times even serious surgical opera
ton Is not regarded as important.
Thus a doctor recently passed as fit
for flying man who had quite large
piece missing from the frontal region
of the skull. 1t Is much more impor-
tant that a man should have both
arms intact than both legs. A clever
pilot who was killed on the western
front was Lord Lucas. who had an
artificial leg.
Considerable Importance Is attached
to the respiratory system. In addition
to good. healthy lungs and vital capac-
ity, the would-be pilot must pass a
breath-holding test. This gives an in
dicatlon of his capacity TO stand the
strain of flying at high attitudes,
where the air is rarefed and breath
Ing is difficult. No man with weak
heart can hope to pass the tests
Self-balancing is another test. The
candidate has to stand on one leg with
his eyes shut and his hands on his
hips. There is also the old test for
sobriety-walking a straight line heel
to toe with eyes open and then turn
ing round and walking back without
losing balance. The Importance of
this test can be understood, seeing
that an aviator flying in a dark cloud
or in fog becomes unconscious of his
position and sometimes the machine
Is actually upside down. II Is essen
tlal that he should not lose a second
In recovering his balance.
The throat. nose and ear are care
fully examined. for any defects might
seriously handicap Il man during the
great strain that all flying imposes.
With regard to the eyes, IL is consid-
cred that pilots should have perfect
color vision, In order 10 pick out the
color or marking of hostile machines
and In recognizing signal lights and In
judging the nature of landing grounds
Air Sickness Rare.
A candidate who suffers from sea
sickness or train sickness would not
be rejected on those grounds alone
Air sickness, caused by the rolling and
pitching of the airplane, is very rare
complaint, and sickness usually occurs
Immediately after landing.
An unstable nervous system suggest
ed by fidgety movements of the hands
feet or face, or biting the nails Is
poor recommendation.
Aero-neurosis Is the name whlch l.
sometimes given to nervous trouble
brought about by the strain of flying
Ii has been said that an airmans litt
consists of "iong spells of idlenes'
punetuated by moments OF intense
fear" He has to. endure intense cold
rain, wind and fog, the nerve-rackinl
noise of the engine, the antiaircraf
fire. and to loop, spin, dive or side
slip. apparently out of control, in or
der to deceive an opponent. An In
teresting nerve test has been devised
In France for selecting the best types
Of airmen for fighting. Around hi'
chest is pneumograph, in his lefi
hand trembler, and around two nm
gers of his right hand pneumatic
"doigtier.'' Behind the candidate {
revolver shot is fired or magnesium

effect on his nerves is obtained by
