Table IX presents a study of the bolls and squares found shed and 
on the "round under the plants recorded in Tables VI and VII. 
The totals of Tables VI. VI L and IX are arranged for convenience 
in Table X. From the tacts thus presented it is found that 18 is the 
average number of good bolls per plant. The normal average has al- 
ready been given as 22. Hence the loss from injury is 18.1' per cent in- 
stead of 26.6, as found by tbe usual method. This difference is Largely 
due to having included the data of Table IX, which represents the 
shed bolls found on the ground under the plants examined. As has 
been shown by Table IV, many of these would have been shed by 
natural process, but were bored before having fallen. Hence, if in- 
cluded, they exaggerate the real damage. The actual damage should 
be estimated upon the basis of the average amount normally matured 
by the cotton plant in any given locality under favorable conditions. 
Omitting Table IX from Table X we have the following results:

The above percentages are obtained upon the ba<i>< of what was 
actually found upon the plant Augu>t 27, without reference to the num- 
ber of bolls normally matured per plant for that locality. The per cent 
of damage is shown to be 1*1.7. which, compared with the L&2 per cent 
obtained on the other basis, shows that this estimate is quite accurate 
and, for all practical purposes, satisfactory.
