picked at the beginning of the test, September 11. None but perfectly 
formed bolls were included in the weighings, thereafter. When af¬ 
fected by weevils the boll was discarded. Seven pickings were made 
covering a period of one month. At the end of that time there were 
still 133 green, unopened bolls on the stripped plants and with very 
few exceptions all the plants in the devastated area were putting out 
new leaves from top to bottom. On October 15 other duties interfered 
and opportunity to examine these plots again did not occur until De¬ 
cember 5. Many unopened and half-open bolls were found on plants 
that held their foliage until frost came and stopped development. 
At the beginning of the test 100 wide open fully matured bolls from 
plants that did not lose their foliage weighed 21 ounces, and the same 
number of similar bolls from plants that had lost their foliage weighed 
19 ounces. It was not expected at this early date, two days after 
stripping, that any difference in weight could be attributed to cotton 
worm work. It would seem to be a natural variation. 
The following record of pickings and weights is interesting:

Average weight of 100 bolls from the stripped plot 16.42 ounces. 
Average weight of 100 bolls from plot with the foliage uninjured 
16.94 ounces. 
All but 16 bolls out of 1,255 can be accounted for on the 123 plants 
in the stripped plot.* No record was made of the entire number of 
bolls on the 250 plants in the plot with uninjured foliage. On both 
plots the opening bolls were of all sizes. 
No significance is attached to a comparison of the number of bolls 
damaged by the boll weevil on the two plots. Accurate record was 
not kept in the plot with foliage uninjured. The weevil-injured bolls 
were left on the plants for the tenant to pick. 
The dried-up bolls were all small and found on both plots, but were 
more readily seen on the stripped plants than on those with leaves. 
* Two bolls were injured by cotton worms and discarded.
