INFLUENCE OF CORN ON THE HOG SITUATION 
It may be seen in Table 3 that there are important correlations 
between the corn variables and the hog variables of the same and later 
The more important of these relations are shown graphically 
rears.

Fig. 16.— The typical variations in corn crop, the price of corn, the price of hogs, the live weight of hogs, 
and western pack and pork production which precede, accompany, and follow a given corn crop 
The summer (S) and winter (W) seasons of six years are represented between the vertical lines, reading 
from left to right. The summer seasons are represented as longer than the winter seasons. The given corn 
crop is represented as determining the relative corn supply for about a year following. The variations 
of all the quantities are assumed to be measured from their respective trends in terms of their average 
(more accurately, their standard) deviations. They are thus simply the correlations as given in Table 3. 
The solid lines are the observed correlations, the dotted lines are those expected on the theory advanced 
in the text and summarized in Figure 27. 
in Figures 16 and 17. The correlation can be interpreted as giving 
the average departure from the trend of one of the variables, in rela- 
tion to a given departure of the other variable, both departures being
