'Data for the Great Plains States — Kansas, Nebraska, North Dakota, and 

 eastern South Dakota — included in the North. 



Note: Supply data for 1952, 1962, 1970 and 1976 are estimates of the trend levels 

 of harvests and differ somewhat from the estimates of actual consumption shown 



in some tables. For the projection years, the data show the volume that would be 

 harvested given the assumptions of the study. 



Inventory data for 1 952 and 1 962 are as of December 31 . Data for 1970, 1977 and 

 the projection years as of January 1
