Then what are people to do In order to
retain the bodily essentials Of youth
or vigor?
Among some Of the tests I con-

sought to lind out first the fatigue In
cident 70 one day in school; next that
resulting from a week of Institutional
work and finally the cumulative IA
tigue incident to the iengthening Pc
riod Of the school term Data taken
In thirteen cases showed an average
fatigue amounting to 9.3 per cent. for
one days work. or to put II In other
terms. 10 per cent. Of the teachers
were physically less efficient at the
end Of the school day than they were
at tho beginning Of the morning ses-
sion. There IL no reason to suppose
that the scholars themselves may not
have been affected quite as radically
in a relative sense"
OF the thirteen subjects 56 per cent.
showed a ~recuperation Of IL per cent.
during the interval between the close
Of school Friday afternoon and the
beginning of the morning session on
the Monday following. This re-
covery Of vitality was much more
marked when the period Of recupera-
ton was extended for ten days. Out Of
the entire group 81 per cent. were
bettered in physical efficiency on an
average Of 3.6 per cent. And DR..
Goldberger says: ut Is Interesting to
note that the longer rest resulted In
twice a. much recuperatton-1.7
per cent. over the week end. compared
to 36 per cent. for the ten day holi-
day."
According to a tabular statement
covering q little YER two months there
was observed depreciation In physi-
cal efficiency Of 7.3 per cent. in 70 per
cent. Of the teachers subjected TO ex-
animation. OF . group Of ffty-three
teachers examined Just before and i'm
mediateiy after their summer vaca-
tons DR.. Goldberger reports:
Seventy per cent. Of the teachers
in this group gained 1928 per cent. in
efficiency. r seven times the arnoun

rests az Per cent?. and three and a
half times the gain resulting from
the ter day holiday. Those teachers
that were out of town from nine TO
ten weeks gained 1877 per cent in Vi
tality: those that were away from four
to eight weeks were benefited 1913
per cent: while those away from one
to four weeks improved s.3 per cent.
The latter group were in wretched
condition when the school year closed.
but because Of the room for improve
ment. they made q greater proportion

shorter vacation. What II equally sig
niAcant is tho fact that the teachers
who continued scholastic work in sum-
mer schools. vacation Fairgrounds or
other Institutional work suffered a
loss Of vitality Of eos per cent. Even
those that were I'll during part or the
whole Of the hummer lost only 1861
per cent. which shows the greater
drain Of continued labor"
The moral TO be drawn from the oh
seryations made Is the need Of rest or
An alienation In the nature OF ones

undeniable evidence Of a persons fund

Why. then. wait until n is thor

Give nature her chance to do'her work
