PURPOSE OF THE STUDY. 
The accompanying tables, graphs, and maps were compiled for a 
study of the marketing of the 1920-21 wheat, corn, and oat crops, 
with the ultimate object of ascertaining a fair estimate of the average 
value per bushel of the entire crop rather than of a specified grade. 
The tables have been compiled in two sections, each illustrated by 
graphs. One section gives cumulative data in 12 steps, each step 
being a complete summary from the beginning of the crop movement 
year to the end of the period. The other section gives monthly 
data compiled from the same figures as were used for the cumulative 
tables and each month is complete in itself. In reviewing the cumu- 
lative tables it should be remembered that all changes of the market 
during the period are averaged in the results. 
METHOD OF COMPUTING PRICES. 
That the reader may be in a position to judge for himself the worth 
of each of the prices used in the tables, a simple explanation of the 
methods of computation follows. The same methods were used for 
each of the grains.
