@esk beering notes from mother - "Pleese excuse Johnny

fror showers today es he has not been feeling rell."
In @ddition to the parede of excuses for showers, my
absence list ves from 4 to 6 tires es long #s under
ordinery conditions. It hed re worried. |

Perdon re, Doctor, wheat type of class work were you
doing et this tire? You know thet might have hed sore-
thing to do with the situetion.

Well, Ded, that edded to my worry, as we were doing
heavy epperatus work et the time, end the students vere
reslly getting e workout. It looked to me as though I
might be responsible for sore of the absences by having
these students do hard rork and then teking » shower.

I believe if they ripe dry it won't hurt them.

Thet wee my ides, but » group of boys in * hurry often
Slight the pert of the shorer about wiping dry end get-
ting the heir wet jfust before going outside. The sit-
ustion looked bed, end I rede un my Wind to see if I

wes Ceuising the trouble. The principel, D. Ws Followay,
geve perrission for re to make a studye I rented to see.
if the same absence rate prevailed sarong the boys not
taking deily physicel education classes. Tro lists vere
mede; first, all the boys taking daily gyrnesiur classes,
307 in number; end second, a list of en equel number of
boys not in physicel educstion. The next step wes to
check the *bsences from school during the three reeks
wren the influenze wes et its worst. After the ebsences
were recorded, it was » sivple thing to add the totals
end see which group w#re ebsent the mosts

Just a moment, Docs We have ® group of people rho are
sick oy injured end heve doctor's excuses from physical

edudation for the entire yeers It would not be feir to
fheve this heéndicapped group ineluded with those not tak-

ing physicel educetion.

I am gled you suggested thet points It was teken care
of by heving the school nurse check the second liste

All the doctor's excuses were filed in her office and
she cut off all the persons excused« We then edded more
students until the second list equalled the number in
the first list. After completing the eddition of the
ebsences we found e total of 474 days absent from school
for the group teking deily exercise, and 600 days #b-
sent from tre non-exercise group. A @ifference of 126

days of extra school rork ras pvatilable for those &n

the exercise group.

Thet #11 sounds very good, but it seers to re thet if
you were to try this agein you might get » different
enswer.

Thet is entirely true, but the methereticiens heave
