EXERCISE 72 

 THE GEOGRAPHICAL DISTRIBUTION OF CORN 



Object. To study the geographical distribution of corn 

 over the United States. 



Explanation. The most important farm crops are usually 

 produced where the conditions of environment are most 

 favorable to their growth and development. The Corn Belt 

 of the United States lies in the Central States in the valleys 

 of the Mississippi River and its tributaries. Nearly all the 

 states produce corn, but three fourths of the corn crop of the 

 United States is produced in less than ten states, which are 

 known as the Corn Belt. 



Equipment. Yearbook of the United States Department 

 of Agriculture. 



Directions. Record in tabular form the total and acre 

 yield of corn for each state in the United States. On the 

 accompanying map show the distribution of corn by placing 

 a star in each state for each 10,000,000 bushels of corn pro- 

 duced. For each state producing less than 10,000,000 bushels 

 record on the map the amount produced.
