Areas Affected With Crazy-Top 
A.— View of a portion of a large crazy-top spot in a field of Mebane cotton. It will be noted 
from the difference in productiveness of the plants that the affected area is very 
distinct. 
B.— Relation of water penetration to effects of crazy-top disorder. The productive plants at 
the left occupy an area where water was impounded at the end of the furrows. The 
greater part of the plants in the area at the right, where water penetration was shal- 
low, were severely affected with crazy-top and produced few bolls
