Pig. 76. — Over one-quarter of the mature horses (2 years old and over) in the 

 United States are in the Corn Belt, and over three-quarters are in the humid eastern 

 half of the country. The small number of horses in the Cotton Belt and the eastern 

 sections of the Corn and Winter Wheat Region is owing in large measure to the pref- 

 erence for mules as work animals in these regions (see Fig. 77). The acres of crops 

 per mature horse and mule in the Cotton Belt (17 acres) is practically the same as in the 

 Corn Belt (18 acres), or in the Hay and Pasture Region (16 acres). The numlxT of 

 horses in cities and villages ("not on farms or ranges") was 1,705,611 on January 1, 

 1920, or about one-tenth the number of mature horses on farms.
