Fig. 77. — About flve-sixths of the mature mules (2 years old aiul over) in the United 

 States are in the Cotton Belt and the Corn and Winter Wheat Rej;ion. In the eastern 

 Cotton Belt (east of Texas and Louisiana), where negro farmers are most numerous 

 (See Figs. 116 and 117), there are twice as many mature mules as horses. The popularity 

 of mules is also increasing in the North and West. Whereas the number of horses 

 over 1 year of age on farms in the United States was only « per cent greater in 1 !)•_'<» 

 than in 1910, the number of mules increased 33 per cent." This rate of increase was 

 almost as great in the North as in the South. Mules, it will be noted, are used on 

 farms in every State of the Union.
