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