The fatigue condition raises the nerva

from one nerve into another. Normal
" a nervous impulse goes along its
nerve directly to the point OF strain.

lus spreads into other nerves as wen

Sir Francis Cation, the great statis-
tic1an, says that the best test he knows
Is that Of restlessness, shown in mus
cular movements. Many times, he
says, he has sat In a position where
ne could watch an audience as it lis
tened to some long scientific memoir.
He took notes OF how people acted
under the strain Of protracted atten-
1on-how often they moved. At the
beginning Of the hour they would sit
quietly; then they would begin 10
move on the average Of once every
four seconds, then every three seconds.
and he says that 1t is possible to trace
right through any audience every de-
gree of fatigue by the number Of mus
cular movements made.
He has simply put together mathe-
matically some data that are familiar
to all of us. We have all seen-and.
alas, been a part of-an audience that
was trying to endure the last half
hour OF an uncomfortable speech. NV
erybody was shifting his position,
crossing one leg over the other or back
again, moving the fingers, playing with
watch charm or chain, yawnfnR
twitching, folding programme. wiping
eyeglasses, adjusting back hair, twist
ing mustache. Those were all fatigue
signs.
A loss of self control in small things
that's the symptom in different terms.
and another name for it is irrftabilHy.
At first it seems strange that this
undue sensitiveness to slight stimuli
should be so sure an effect of fatigue;
but 1t means that the resistance gates
are down and we become aware Of
sensations pouring in from all sides.
slight sensations that ordinarily we
take no notice of because-by the laws
OF attention-they are quietly shut out
from our consciousness. But when our
attention is tired-no longer focused,
but scattering-all these slight nerve
pricks attack us insistentIy and we
cannot neglect them.
A noise that you will not hear when
you are rested VIII be perfectly dis
tracing when you are tired. You win
go over and shut a window; you win
walk around aimlessly; you will swear
at the faint crackle Of distant graphic
phone. If there is a light above you
at an evening lecture 1t viii hurt your
eyes almost beyond endurance. In
stead Of making the nervous system a
less responsive instrument, fatigue
makes it more responsive-more re-
sponsive, but less serviceable.
Every man who is anxious to hit his
job between the eyes should make a
study of his own fatigue curve, and
be should put the moral Of It to heart.
To know when it's time to quit-and
