MAV|IliA| IA CORPS.
Candidates For AIrmen Must
Meet Rigid Requirements;
MANY ARE REFUSED DAILY

but Must havs Acute Eyssisht and
Balance Of Touch 10 Also
Carefully Examined by Physieians,
and Many Refused on These Grounds.
Perfect physical condition is only one
Of the requisites Of the aviator, and the
degree of perfection desired is far be-
You'd that expected In any other branch
Of the government military service.
But to top this of, the finest organs,
perfect limbs and all around physical
proficiency count as nothing unless the
candidate for place in the aerial
corps can pass series Of tests which
for ingenuity Of search are appalling to
the man under the probe.
Strong, vigorous youths who could At
into any other branch of the service are
daily refused In aviation because their
lack Of balance, the sixth sense, which
few knew any possessed, would con-
denim them to speedy death, or because
of their inability to distinguish browns
from green's at great heights would
cause them to drop into treetops in
stead of plowed fields.
Whispering Test Next.
The candidate must fall within the
weights of 120 pounds as a minimum
and 100 pounds as a maximum. After
each man is credited with his mark for
physical fitness and soundness of the
organs his hearing is sexamined by the
whispering test at distances Of twenty
feet.
All possible diseases are then inves
tigated. Each man is sounded and ex-
amtned from the top of the head to the
soles of his feet If any has skin dis
ease, varicose veins or other complaints
Of similar nature he is counted out
until cured. Flat feet, unless they are
| Of very serious nature, are not bar
| to the aviator, as he is not compelled to
march.
The dynamic test follows. This is
the first deviation from a general physi-
cal examination. Each candidate is
compelled to stand In a corner of the
room and walk diagonally forward
with eyes shut and then walk back
ward to the point from which he start
ed. This tests his sense of direction.
The Vital Sixth Sense.
The most interesting part remains.
That is to discover how well developed
In each man is the vital sixth sense,
the principle Of eQuilibration. An ex-
pert on this subject explains it as fol-
| lows:
I'm each ear are three tiny canals
filed with lymph. These really are the
spirit levels of the body. Movement in
any direction is communicated through
the flow of the fluid In these tiny ca
mails to sensitive nerves, which carry
the impression to the brain. This or
gan in turn sets about correcting the
balance in the normal method"
Then begins the test Of balance. The
candidate Is seated in an armchair
working upon pivot, with a, head
rest for security and tall handle pro-
jecting above, by which the chair can
be turned. The youth is told to fasten
his eye upon an object and then close
his eyes.
The chair is then spun rapidly to the
right, ten revolutions in twenty Sec
onds. AS it is stopped suddenly facing
the stationary object the candidate
opens his eyes and endeavors to focus
them upon the object. The dizzy mo.
ton causes the eyes to jerk rapidly
from side to side until they regain
their natural control. Twenty-six sec.
onds are allowed for the nerves to re-
gain control. Then the same test Is
performed with the spinning to the
left. This test shows the rapidity with
which the candidate regains control OF
his balance after being violently twist
ed and turned.
Testinq Sense Touch.
The spontaneous touch test next il
in order. The candidate closes his
eyes. The physician standing before
him at arms length holds his index
finger so that the youths finger rest:
upon it. He is then ordered to raise
his arm and allow it to descend grad
ually to see whether it will come bacl
to the same point Of contact
This was no very severe task, bu
that which followed was one of tn,
!. hardest Of the day. The man is spur
J in the chair as fast as It can be turnet
and then, when brought to a standstil]
is compelled to raise and lower eac]
arm alternately three times in success
sion in sixteen seconds to see how IA
past the point of touch his finger vii
