different classes of fruit is shown for each of the treatments.

The apparent average loss per tree from spraying in bloom 
was nine-tenths of a bushel of marketable fruit, but including 
all grades it was only six-tenths of a bushel. With trees stand- 
ing 30x30 feet apart, making 48 trees per acre, the loss of mar- 
ketable fruit at this rate amounts to 43 bushels per acre. This 
fruit would have readily sold at picking time for $1.25 per barrel 
so that the apparent loss in yield might be conservatively esti- 
It should be noted that tree No. 18 of Row 2 was somewhat smaller than 
the other trees under experiment: also tree No. 16 of Row 8 and tree No. 16 
of Row 4 had but a medium amount of bloom. If these are excluded the 
average yield per tree of those sprayed in bloom is 13.56 bushels and the 
average per tree for trees not sprayed in bloom is 14.91 bushel per tree. In _ 
this ease the average for trees sprayed in bloom is 1.35 bushels per tree 
iess than for trees not sprayed in bloom,
