which dropped. The difference in the amount of fruit on trees 

 of Alexander, Twenty Ounce and Oldenburg which were 

 sprayed in bloom and corresponding trees of these varieties 

 which were not so treated was not great enough to be deter- 

 mined from inspection as late as August 16. The Oldenburgs 

 were picked August 21 and graded by Mr. Collamer into three 

 grades as shown in his report which follows. No record was 

 kept of the drops, but the amount was relatively large when 

 compared with the amount of picked fruit.

From this it appears that the average loss of picked fruit per 

 tree was 20 lbs., or about two-fifths of a bushel. It is but fair 

 to say that this variety, the Oldenburg, is not well adapted for 

 a test of the effect of spraying in bloom on the yield, because 

 the fruit does not ripen so that it can all be picked at once, and 

 consequently it is not easy to keep an accurate record of the 

 drops and of the different grades of marketable fruit. 



Four trees of Pumpkin Sweet were sprayed in bloom, and four 

 corresponding trees were not sprayed in bloom. On August 16 

 the following notes on these trees were made: 



Row 3, sprayed in bloom. 



Tree 1. — No fruit on the tree. 

 Tree 2. — But little fruit on the tree. 

 Tree 3. — But very little fruit on the tree. 

 Tree 4. — But very little fruit on the tree. 



Row 4. not sprayed in bloom. 



Tree 1. — But very little fruit on the tree. 



Tree 2. — But very little fruit on the tree. 



Tree 3. — But very little fruit on the tree.
