On June 2 typical branches were selected and a record was 

 made of the number of fruits which were found in the same 

 way as was done with the Mcintosh tree. The results are sum- 

 marized in the following statement of the number of fruits 

 which set on typical branches sprayed repeatedly in bloom com- 

 pared with the number which set on typical branches which 

 were not sprayed in bloom.

 be made. All through the season this tree furnished a most 

 striking object lesson of the effect which spraying in bloom may 

 have upon the yield of fruit. The half of the tree which 

 was sprayed repeatedly during the blooming season ripened prob-
