Fig. 10. — Over five-sixths of the crop land is in the humid eastern half of the United 

 States, and nearly two-thirds is concentrated in the triangiUar shaped area described 

 under Figure 9. In this area, which includes only about one-fourth of the land of the 

 United States, are produced four-fifths of the corn, three-fourths of the wheat and i 

 oats, and three-fifths ot the hay crop of the nation. Ko region in the world of equal, 

 size affords so favorable natural conditions for the growth of corn, and few regions; 

 possess so favorable conditions for the culture of the small gi'ain and hay crops. (See 

 Figs. 24, 29, 30, 32, 33, 34, and 38.)
