between fallen and hanging squares or bolls. However, taking the 
figures as they are, we have the following results:

BREEDING RECORDS OF 1906. 
Although the work of 1906 was very incomplete in some respects, 
it is representative of the conditions. The facts have been ascer- 
tained one at a time, and as each one has been proved, it has been 
found that more complete records should have been taken earlier in 
the season. The material was collected at 25 representative locali- 
ties in Texas, 2 in Indian Territory, and 5 in Louisiana. Seventy 
collections of infested forms were made, comprising about 87,000 
bolls and squares. The result is that these infested forms contained 
39,183 weevil stages, of which 1,689, or 4.31 per cent, were para- 
sitized. The material collected was separated into lots, according to 
location and the nature of the forms. 
A brief classification of the results, by months and by the four 
plant conditions, gives some very important information. In the 
first place, the percentage of parasitism is, to all intents and pur- 
poses, about equal throughout the season and not highest in the fall. 
It must, of course, be borne in mind that the collections were not 
made at regular intervals at stated places, but are from different 
localities each month and include different factors. During Sep- 
tember and October a number of localities on the extreme border 
line were examined, but the percentage is not appreciably altered. 
The plant conditions were altered also, so that one month there 
might be more squares than bolls, and another month more bolls than
