COTTONSEED OIL. 



The 10 experiments summarized in Table XL were made with cot- 

 tonseed oil dming 1912 and 1913. This oil was emulsified in all cases 

 exactly as kerosene oil is emulsified in the preparation of kerosene 

 emulsion. The sprays were applied in experiments 3, 4, 5, 6, and 7 

 with a hand sprayer and the applications were so thorouglily made 

 that every scale was covered. The sprays in the other experiments 

 were applied with a power sprayer.
