 were adopt' 1 *! and at once placed in effect. 



1904 



The work of the Commission during 1904 was entirely un- 

 der the direction of Prof. II. A. Morgan. 



At the beginning of the year the only territory in Louisiana 

 known to be infested by the boll weevil was in western Sabine 

 Parish. This infestation the Commission exterminated by in- 

 ducing the farmers in the affected territory to abstain from the 

 planting of cotton during 1904, the planters and farmers being 

 paid a cash rental for the acreage thus 'thrown out" of cotton 

 during that season. 



An infestation discovered near Logansport in July, 1904 > 

 was also exterminated. More particular references to these are 

 made in Circular No. 5 of the Commission, copy of which is sub- 

 mitted herewith. 



In August, 1904, Prof. Morgan discovered that the boll 

 weevil, in addition to being disseminated artificially in hulls, 

 cotton seed, etc.. possesses a migratory habit, which manifests 

 itself during late summer and autumn. This migration of the 

 wevils, during the summer and autumn months of 1904, carried 

 the infestation again into the territory where the pest had been 

 exterminated, and, in addition, gained for it about twenty 

 miles to the eastward. The discovery of this habit of the insect 

 entirely revolutionized the methods to be employed in limiting- 

 the weevils' progress, and the quarantine regulations, which 

 had previously been enforced to the extent of causing serious 

 Inconvenience to business interests, were supplanted by regula- 

 tions fully as effective in preventing the artificial spread of the 

 weevil and entailing no loss to individuals or business interests. 



These regulations have, up to the present time, been entirely 

 effective in preventing the weevil from obtaining a foothold in 

 Kastern and Northeastern Louisiana. Had it not been for the 

 enforcement of these regulations there can be but little doubt 

 t'ftt there would now be many local centers of infestation in 

 the ; ,rea (four-fifths of the State) still free from this pest.
