This statement shows clearly that even spraying once in bloom 

 may lessen very much the proportion of fruit which sets. Fig. 1, 

 Plate LVII, shows a cluster from the Baldwin tree which was 

 sprayed in bloom, as it appeared June 5. This illustrates the 

 kind of injury which may follow the spraying of trees when in 

 bloom. None of these blossoms have set fruit except possibly 

 one of the latest on the outside of the cluster which seems to 

 have swollen somewhat and might have developed into fruit. 

 Fig. 3, Plate LVII, shows a cluster which was taken on the same 

 day from the corresponding tree not sprayed in bloom. This 

 shows how abundantly the fruit set on these Baldwin trees where 

 the blossoms were not hit by the spray. 



Plate LVIII, Fig. 1, shows a cluster from a Twenty Ounce tree 

 sprayed once in bloom. The treatment killed the central blos- 

 som but the later outside blossoms set some fruit. Fig. 2 shows 

 another cluster of the same variety in which none of the blos- 

 soms survived the treatment. The table shows the number of 

 fruits which set on typical branches sprayed but once in bloom 

 compared with the number which set on typical branches not 

 sprayed in bloom.
