Fig. 49. — The regions of heaviest potato production lie to the north of the Corn Belt. 

 This is due partly to the fact that the quality and yield of potatoes are better in regions 

 of cool climate, and partly to the fact that corn, which requires labor at the same time, 

 is very productive and gives a greater return. Many of the large centers of potato^ pro- 

 duction are in regions of sandy or loamy soils — Aroostook County (Me.), Long Island, 

 New .Jersey, ea.stern Virginia, western Michigan, central Wisconsin, and Anoka County 

 (Minn.). Many of the minor centers of production are located near large cities, since 

 potatoes are a "bulky crop, expensive to transport, and can be sold at a profit by local 

 gardeners and farmers in competition with the crop from the large production centers.
