 were quite similar to those which were found with the second 

 crop. With the fourth crop the evidence was stronger than before

 only superior to that which was grown on the sandy soil, in tex- 

 ture of leaf, firmness of head and general appearance, but it was 

 also heavier. In the last-named particular the results differed 

 from those which were obtained with Oops II and III but other- 

 wise they do not conflict with them.
