be combmed \vitli rotation of crops, using, for two or three years 

 previous to planting cotton on tbe land, some of the grasses or grains 

 best adapted to the requirements of the particular locality. This 

 course has proved most practicable and successful in combating this 

 disease. 



In order to attain success by this method the plomng must be 

 very thoroughly done and at the proper time. Good results can 

 not be secured unless the land is plowed to a depth of at least 7 

 inches, and 9 inches would be still better. This work cannot be 

 done ^\iih. the small plows in general use by cotton planters. A 

 good disk plow or a 12 to 14 inch plow of the ordinary form must 

 be used. In the experiments of the writers the plomng was done 

 early in December. We believe it would be better to do it in 

 November, as the soil would have a greater opportunity to become 

 aerated; but if it is impossible to do the plowing in the fall it 

 should be done during the winter or early spring.
