after which the whole mixture was stirred vigorously in order 
that the entire “ sloppy ” mass should be thrown into suspension. 
It was then pumped back into itself with the spray pump for from 
three to five minutes to insure a thorough emulsification of the in- 
gredients. 
THE ORCHARDS. 
The orchards in which the treatments were made are located in 
Ontario Co., at Geneva; in Suffolk Co., at Northville; and in 
Niagara Co., at Youngstown. The conditions were the same as 
those given in the previous section for Orchards II, IV and V. 
In addition an orchard was selected for the summer spraying in 
which the trees were about forty years old and very badly scale 
infested. At Youngstown a portion of an apple orchard of 400 
trees which was infested with scale received the spring treatment. 
with this mixture in comparison with the recognized standard 
sprays. | 
The total number of trees under experiment was 6738, of stand- 
ard varieties of apples, peaches and plums. 
DISCUSSION OF EXPERIMENTS. 
FALL TREATMENT. 
Orchard IV; Plums.—In this orchard 63 Burbank and Reine 
Claude plums, and two small cherries were sprayed. These trees 
in the past had been very productive and were thrifty. Local 
hydrated lime was used and applications containing 10 per ct., 
15 per ct., 20 per ct., 25 per ct., 30 per ct., 35 per ct. and 40 per 
et. of oil were made. The preparations having the higher per- 
centages of oil were applied with difficulty as the washes were 
very heavy because of the small quantity of water used in pro- 
portion to the amount of lime employed. For purposes of com- 
parison some trees were treated with a 10 per ct. limoid-kerosene 
wash. 
Results: Hydrated lime mixture, 10 per. ct. oil.—This mixture 
was applied to 13 Reine Claude plums, each tree being numbered 
with respect to the order in which it was sprayed. On May 10 
trees 1 and 2 were severely injured, the only evidence of life be- 
ing scattering blossoms and leaves on the tips of the highest 
branches. With the coming of summer these trees gradually
