Fig. 22. — The typical variations of the quantities indicated along the left margin in relation to a given 
variation in the western summer hog pack. The solid lines represent the observed variations (corre- 
lations), the dotted lines, those expected according to the theory advanced in the text. The vertical 
lines separate the longer summer and shorter winter seasons of six years (see legend of fig. 16)
