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 50 years old. The top branches could 
not be reac ~— with the spray 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. 
FALL PIPPIN SPRAYED REPEATEDLY WHILE IN BLOOM. 
Date of 
treatment. Condition of bloom. 
May 16.... About 12 per ct. of the blossom buds are now open. None 
but the center blossoms have yet opened. 
DLR LS S22 None but center blossoms have yet opened and not all of 
these are open. 
May. 19... Rain yesterday prevented spraying. Perhaps 20 per ct. to 
25 per ct. of all blossom buds are now open. 
May 21%’... Probably 75 per ct. of blossom buds have opened. But 
few clusters have all blossoms open.

May 25.... The petals have fallen from about three-fourths of the 
blossoms.

May 27; it, 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
