Proceedings of the Boll-Weevil Convention in Ne^w Orleans {New Oiieuns: 

 Bureau Agr. and Immig., 1903, pp. 9^).— A convention for the consideration of the 

 lx>ll-weevil problem was called by Gov. W. W. Heard, and held sessions in New 

 Orleans, November 30 and December 1, 1903. At these meetings a number of speak- 

 ers took an active part in the discussion, and various papers were presented on differ- 

 ent aspects of the boll-weevil problem. The distribution and general economic 

 aspects of the question were discussed by A. Brittin and C. Schuler. J. H. Connell 

 sjtoke on the prospects of the cooperation of this Department in combating the boll 

 weevil. An account was also given of the spread of the insect and the difficulties to 

 contend with in exterminating it. 



\V. D. Hunter referred to the work which has already been done by this Depart- 

 ment in fighting the boll weevil in Texas. The speaker stated his opinion as being 

 that extermination of this insect is impossible. Attention should be directed to 

 keeping the pest in check by means of proper rotation of crops and cultural methods. 

 The j)roblem of protecting Louisiana against invasion by the boll weevil was dis- 

 cussed by H. A. Morgan. Attention was called to the importance of the fact that 

 ill the United States cotton is the only known food jalant of the boll weevil. This 

 fact may be made use of in a system of rotation for preventing invasion by the pest. 

 The habits of the insect were described in detail for the purpose of illustrating feasi- 

 ble methods of eradication. 



S. A. Knapp referred to the interest manifested by the Secretary of Agriculture in 

 checking the ravages of the boll weevil, and outlined the methods of procedure 

 which have been adopted on demonstration farms. The speaker stated that the 

 results obtained on such farms have been so satisfactory as to induce many other 

 farmers to put the same methods in practice. The legality and constitutionality of 

 proposed legislation for preventing the spread of the boll weevil from Texas into 

 Louisiana were discussed by J. C. Pugh and W. Guion. 



The morning session of December 1 was devoted largely to a discussion of the 

 economic importance of the cotton-boll weevil to various commercial interests. The 

 planters' interest in combating the boll weevil was discussed by F. P. Stubbs; the 

 merchants' interest, by J. M. Parker; the bankers' interest, by S. M. Lawrason, and 

 the oil mills' interest, by S. P. Sullivan. The speakers described the injurious effects 

 of the unrestricted sjjread of the boll weevil upon the development of the various 

 industries. 



F. M. IMuUer read a paper on Birds in their Kelation to the Boll Weevil. In this 

 paper attention was called to the importance of birds in controlling the injurious 

 insects and the necessity of protecting the most beneficial birds. Resolutions win-e 

 adopted calling upon the farmers to exercise unusual precaution in jjreventing the 

 importation of the boll weevil, urging cordial cooperation with this Department, and
