 and partial perishableness. 



Most of the potatoes raised in the Upited States are 

 still grown as a cash crop in relatively small parcels on 

 many farms. There is a tendency, however, toward the 

 development of potato-growing centers in widely sepa- 

 rated sections of the United States. By a careful inspec-

 are located in Aroostook County, Maine, the Norfolk and 

 Eastern Shore trucking regions of Virginia and Maryland, 

 the Red River Valley of Minnesota and North Dakota, 

 the Kaw Valley of Kansas, the Greely and Carbondale 

 districts of Colorado, and the San Joaquin and Sacramento 

 valleys of California.
