PROLIFERATION FROM FEEDING PUNCTURES IN SQUARES. 
As the square precedes the boll in the natural process of develop- 
ment and the feeding puncture precedes oviposition in the attack 
of the weevil, we shall consider first the observations regarding pro- 
liferation resulting from feeding punctures made in squares. 
PROLIFERATION IN CONTROL OF BOLL WEEVIL. 
These 
: : ‘ty 
observations include nearly 25 varieties of cotton. They are grouped : 
by years and localities in order to bring as closely together as is possi- 
ble those records which may be considered as most strictly compar- 1 
able. The totals and averages for so many seasons and localities ; 
should constitute a very fair average statement of the true condition. —

a Weighted average. 
The general average for all the various seasons and localities 
shows that in squares approximately one-half of all feeding punc- 
tures stimulate proliferation. The highest percentage shown is 75.6 
per cent in ‘‘Jannovitch” (an Egyptian variety), at Victoria, Tex. 
on October 22, 1903, while the lowest percentage found was 12.9
