Fig. 74. — One-1)hird of the hoise.-< in the United States are raised in tlie Corn Belt, 

 one-si.\th in the (ireat Plains Region, one-tenth in the Spring Wheat Area, and one- 

 twelfth in the Kansas-Oklahoma section of the Corn and Winter Wheat Region. These 

 are the regions of surplus grain and cheap forage. Comparatively few horses are raised 

 in the Cotton Belt, or the Central and North Atlantic States, because these are regions 

 of deficient grain production and feed must be shipped in at heavy expense. It is more 

 economical to ship the mature horses into these deficiency regions than to ship the grain 

 to grow them. (See Figs. 11, 12. 27, 32, 33, 36, and 41.) 



MULE COLTS, JAN. I, 1920 



Fig. 75. — Two-thirds of the mules are raised in the western section of the Corn and 

 Winter Wheat Region and the southern portion of the Corn Belt, the centers of 

 production being about 300 miles south of the centers of horse production. This may 

 be due in part to the adaptation of the mule to warmer temperature than the horse, 

 but also in part to the shorter distance and smaller cost of transportation to the Cotton 

 Belt, where most of the mules are sent (see Fig. 77). Formerly Kentucky and Ten- 

 nessee were the leading States in mule production, but now a much greater number are 

 raised in Missouri, Kansas, and Oklahoma, where feed is cheaper.
