This shows no decided gain by any treatment. Even the 
unsprayed trées gave good results. At picking time, In October, 
the difference between the crops was indistinguishable. 
Experiment 2 (SJackson)—{1) The east sides of four well-grown 
Maiden Blush trees were sprayed on Saturday morning, May 19. 
About five gallons of Bordeaux were applied to each half tree. 
All the sides showed an abundance of bloom, and about ninety 
per ct. of the blossoms were open at the time of spraying. 
Weather cool and partly cloudy. A slight wind carried a little 
spray over to the west side of the trees. (2) On Saturday, June 
9, when the fruit had set, the west sides of these four trees were 
sprayed. All of the trees had been sprayed alike with the Kedzie 
mixture by Mr, Jackson before the blossoms opened. 
At the second spraying, June 9, and on August 20, these records 
were taken:

The parts sprayed in bloom gave the better results. 
Experiment 8 (Jackson).—-Most of the trees of Twenty Ounce 
in Mr. Jackson’s orchard are badly attacked by apple canker. 
The four trees used in this experiment, although affected, are 
still thrifty. (1) On Saturday morning, May 19, the east sides 
only of these trees were sprayed at the rate of four gallons of 
Bordeaux to each half tree. The trees were then white with 
bloom. Weather cool and partly cloudy, becoming warmer in the 
afternoon. (2) On Saturday, June 9, when the fruit had set, 
the west sides of the trees were sprayed. Weather slightly 
cloudy. 
Following are the records taken on June 9 and Augus. 20:
