19
were not active. The remaining part of the circle is divided be-=

tween intermissions and interruptions (14.38 and 18,02 minutes ree
spectively).

The averace per cent of activity for all positions in cone
nection with the time allowed by rules (8 minutes per quarter) is
as follows: First quarter 25 per cent, second quarter 26 percent,
third quarter 26.7 per cent and fourth quarter 28,5 per cent. This
showed an averagé increase of 3.5 per cent of activity for the last
ennieer over that of the first quarter. The average per cent of
activity of movements with reference to the total elapsed time was
17.5, 17.2, 17.0 and 16.4, or a decrease of 1.1 per cent of activity
between the first and fourth quarters; the per cent readings being
from the first to the fourth quarter,

This study showed that the proportion of interruptions in-
creased as the game progressed - from 30.9 per cent of the total
elapsed time for the first quarter to 42.6 per cent for the fourth
quarter, an increase of 11.7 per cent for the fourth quarter over the
first quarter,

The percentage of non-activity showed a deerease of 10,6
per cent for the last quarter over the first quarter, The percent»
age of activity, interruptions and non-activity by quarters is shown
By four small circle drawings in Plate I=B, The circles represent
the average total elapsed time for completing each quarter. Each
quarter being divided into three parts. A- interruptions; B- activity
and C- non-activity,

The time distribution of activity and non-activity per
quarter and for intermissions in sequence for an entire game is shown

in diagromatic form in Plate II, The average time spent to complete
