a Weighted average. 
Two rather striking contrasts are shown by a study of the figures in 
this table. First, in the 1,040 King squares examined there were 
found 417 weevil stages, while in 672 Shine squares examined there 
were found 543 stages. Stated in a way to make the contrast most 
evident, in King there was found an average of one weevil stage for 
each 2.5 squares; in Shine an average of one weevil stage for each 1.24 
squares. That is, in Shine there were almost exactly twice as many 
_ weevil stages found; in proportion to the number of squares examined, 
asin King. This is a factor, however, which would naturally vary 
widely with the degree of infestation found in the field and it is a well- 
_ established fact that weevils were much more numerous and injurious 
at San Antonio in 1905 than they were at Calvert, Tex. The second 
striking contrast is to be found in the percentage of mortality. In 
King squares without proliferation only 0.9 per cent of the weevil 
stages found were dead, while in Shine squares without proliferation 
ten times as large a proportion, or 9.1 per cent, of the stages found 
_ were dead. Doubtless much of this difference may have been due to 
‘seasonal rather than to varietal differences, since it appears that in 
King squares at Calvert in 1905 the percentage of mortality was much 
. greater than at Victoria in 1904. 
In other respects there is a most striking uniformity in the results 
shown. The percentage of squares showing proliferation varies only 
; 
between 49.7 per cent for Shine and 54 per cent for King. The
