During 1902, 1903, and 1904, cotton was grown continuously on Field 

 A and corn on Field B, but since that time up to the present, these two 

 crops have been grown in rotation in alternate years on the two fields. 

 In Tables YI and VII are given the results secured with cotton and 

 corn on the different plats of the two fields at this farm.
