PLATE VIII. 



Fig. 1. — In the foreground, cotton on the plot fertilized with 

 dried blood. In the background, cotton on the plot fertilized 

 with cotton seed meal. Cotton was the only crop that was 

 notably injured on the plots fertilized with cotton seed meal.

 is making a better growth than on the plots fertilized with dried 

 blood or cotton seed meal.
