All statistics concerning apple production have a "break" in 1934 

 when the basis of reports was changed from "total production" to "com- 

 mercial production". Consumption data have a similar break since they 

 are obtained by subtracting quantities iinharvested and quantities used 

 on the farm from total production. The consumption rates shown in 

 Table 1 were therefore broken from 1932 to 1935. When trend lines 

 are fitted by the method of least squares. Chart 1 shows that the rate 

 of decline in per capita consumption of fresh apples was smaller in the 

 latter period. The rate of per capita consumption of processed apples, 

 however, increased during the latter period after declining from 1920 

 to 1932. This can be best explained by the diminishing rate of consump- 

 tion of dried apples and the increasing rate of consumption of canned 

 and frozen products. As the use of dried apples declined during the 

 early period and the per capita consumption of canned apple products 

 remained about constant, the total rate of consumption of processed 

 apples declined. During the later period, the per capita consumption 

 of canned and frozen apple products (the latter initially appeared in 

 consumption figures in 1938) increased as shown by the trend line fitted 

 to per capita consumption of processed apples in Chart 1.
