to > this problem seemed to make acceptance of that chance preferable 

 to^ postponement for the minimum period of 2 years required to set 

 up controlled cotton-peanut rotation experiments. 



Flavor scores for the 1951 commercial samples from South Carolina 

 are presented in table 4. Panel A scored all and Panel B scored 4 

 of the treated samples significantly lower than the control. Both 

 panels scored 2 of the 3 untreated samples significantly low. In view 

 of these low scores for 2 of the 3 untreated samples the results provide 

 little basis for attributing the low scores given the treated commercial 

 samples to growth of the peanuts in rotation with BHC-treated cotton. 

 It may be noted also that the control sample was an exceptionaUy 

 well-flavored peanut butter and was scored high by both panels.
