ably less than a peck of fruit. The opposite side which was not 

 sprayed in bloom bore a very heavy crop; so heavy, in fact, that 

 the windstorm referred to broke down the limbs on that side 

 and ruined the tree. 



A Fall Pippin apple tree was selected for a similar test and a 

 corresponding tree of the same kind which appeared to have 

 about the same amount of blossom buds, was chosen for com- 

 parison. These trees were 5'0 years old. The top branches could 

 not be rear ^ with the sipray well enough to insure thorough 

 application to the blossom clusters, accordingly only the lower 

 parts of the tree which could be readily reached with the 

 extension rods used in applying the spray, were included in the 

 test. The dates on which the treatments were made appear in 

 the following statement.

Cordition of bloom. 



About 12 per ct. of the blossom buds are now open. None 

 but the center blossoms have yet opened. 



None but center blossoms have yet opened and not all of 

 these an> open. 



Rain yesterday prevented spraying. Perhaps 20 per ct. to 

 25 per ct. of all blossom buds are now open. 



Probably 75 per et. of blossom buds have opened. But 

 few clusters have all blossoms open. 



The petals have fallen from about one-half of the blos- 

 soms. 



The petals have fallen from about three-fourths of the 

 blossoms. 



The petals have fallen from perhaps 90 per ct. to 95 per 

 ct. of the blossoms. No further spraying in bloom was done 

 to this tree. 



On June 4, typical branches from this tree and from the corre- 

 sponding tree which was not sprayed in bloom were compared, 

 and the following records of the fruits which were found were 

 taken in the way described above for Mcintosh. Plate LVI, 

 Fig. 1, shows a cluster of Fall Pippin sprayed in bloom while a 

 corresponding cluster from the Fall Pippin which was not
