1 This table does not include the newly infested area in Arizona, as the extent of this is still problematical. 



^ Table II gives a distinct idea of the importance of the uninfested territory from the standpoint of cotton production. The distribu- 

 tion of production throughout the country has been summarized for the 10-year period 1909-1918, inclusive, and this production has been 

 distributed within each State between the infested and uninfested areas as shown by the 1920 dispersion line

1 This table does not include newly infested territory in Arizona. 



In Table II it is shown that only 8.5 per cent of the Texas crop is produced bevond the weevil-infested area. In Oklahoma 28.8 

 per cent is produced outside the weevil line, and in Arkansas and Tennessee the percentages are 28.8 and 67.3, respectively. Georgia 

 shows practically complete infestation, as it produces only one-tenth of 1 per cent of its crop beyond the weevil line. In South Carolina 

 only 14.8 per cent is produced in the uninfested section, while in North Carolina the infested area produces only about 10 per cent of the 

 crop in that State. Considering the cotton-producing States as a whole, it is seen that a general average of 16.2 per cent of the total cotton 

 crop is produced m uninfested territory. This shov/s the small amount of territory which is still possibly subject to weevil infestation 



We are indebted to Prof. Franklin Sherman and assistants, of the North Carolina Department of Agriculture, for assistance in detei 

 mining the advance of the weevil. Most of the work was done by the following agents: E. S. Tucker, F. F. Bondy W B William'^ 

 and R. W. Moreland. j • •
