EXERCISE 75 



THE GEOGRAPHICAL DISTRIBUTION OF 

 POTATOES 



Object. To study the geographical distribution of 

 potatoes over the United States. 



Explanation. Potatoes are generally grown throughout 

 the United States, but the localities in which they develop 

 best are restricted. Maximum yields are usually produced 

 on a well-drained, sandy loam soil that contains an abun- 

 dance of humus. 



Equipment. Yearbook of the United States Department 

 of Agriculture. 



Directions. Record in tabular form the total and acre 

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

 accompanying map show the distribution of potatoes by 

 placing a star in each state for each 5,000,000 bushels of 

 potatoes produced. For each state producing less than 

 5,000,000 bushels record on the map the amount produced.
