Mr. W. D. Hunter, in charge of the government cotton boll 

 weevil investigations, made the opening remarks, speaking of 

 the development of the quarantine rules, the changes made in 

 the various State regulations since the previous meeting at 

 Jackson, Miss., and of the changes which were advisable at 

 the present time, in order that no unnecessary restrictions to 

 interstate commerce be continued. 



Prof. H. A. Morgan gave in some detail his experience in 

 attempting to check the spread of the weevil into the State of 

 Louisiana during the seasons of 1903 and 1904. Believing the 

 principal means of dissemination was through shipments of 

 cotton seed and seed cotton, the Louisiana authorities .started 

 out to test the possibility of checking the boll weevil's spread. 

 Careful observations in the field revealed a clue to the possi- 

 bility that the weevils migrated by flight at certain seasons of 

 the year. Co-operating with Mr. Hunter and his assistants, 

 of the Bureau of Entomology, the migration in 1904 was care- 

 fully studied, and all the evidence obtained pointed to this as 

 the leading method of the weevil's .spread. The distance cov- 

 ered by the migrating weevils varied from 20 miles in northern 

 Louisiana to about 70 miles in southern Louisiana. At Jen- 

 nings, Louisiana, an isolation from all other cotton fields of 14 

 miles proved to be no protection to cotton growing there. 



Messrs. Morgan and Hunter spoke of the evidence obtained 

 last season to the effect that the weevils fly high during their 

 migration. Extensive beatings outside of cotton fields during 

 the migrating season did not result in the capture of a single 

 specimen and, as additional evidence, the weevils when spread- 

 ing into uninfested territory were found farther into a field 

 where it was bounded by timber on the south or west side than 

 where there was no such timber present. 



Representatives from the various States reported on the 

 status of the boll weevil quarantine laws. Those of Missis- 

 sippi, Alabama and North Carolina were in accord with the 

 resolutions adopted at the meeting of the Association at Jack- 

 son, Mississippi, August 2, 1904. The quarantines maintained
