a The records were taken three days after the apples were removed from storage. During the after-storage 
p i* ico the fruit was held at a temperature of approximately 70° F. The percentages show the general 
severity of the disease, allowance being made for the surface area scalded, and the intensity of the scalds 
as well as the number of apples affected.

o An apple was counted as having slight scald when it had but a slight touch of brown that probably 
would have little if any effect upon its market value. When worse than this it was counted as having bad 
slcald. The percentages in the last column give the general severity of the disease in one set of figures 
alowance being made for the surface area scalded and the intensity of the scald, as well as the number of, 
apples affected.
