PRUNE AND CHERRY BROWN-ROT IN THE NORTHWEST. 7 
was beginning to color. There was very little blossom infection in 
either orchard. Lime-sulphur again caused some injury to the 
foliage, but not quite as much as in the previous year. It was also 
found that the addition of 4 pounds of lime to each 50 gallons of 
lime-sulphur resulted in materially reducing the follage injury. 
The prunes from the Felida orchard were harvested on September 
12 and 23. Fruit from the first picking was shipped in pony 
refrigerators to Washington, D. C., received in good condition on 
September 19, and held at a temperature of 70° to 80° F. till Septem- 
ber 23, when notes were taken. There was practically no rot on the 
prunes in the Salem orchard. They were harvested September 6; 
sound fruit was shipped by ordinary express to Wenatchee, Wash.,

Fic, 2.—The effect of spraying upon the development of brown-rot on Italian Prunes 
in the orchard and after harvest; experiments of 1916, 
and held at room temperatures till September 16, when the notes 
shown in Figure 2 were taken. 
The results again emphasize the great value of spraying in im- 
proving the holding and shipping quality of the fruit even when 
the orchards are practically free from the disease. 
SPRAYING EXPERIMENTS IN 1917. 
The spraying experiments were continued in the Felida orchard 
in 1917. The spray mixtures were the same as those used in the 
1916 experiments except that an additional plat was treated with a
