16 THE HORSE, ASS, AND MULE 



Societies for promoting Arab horses are found in various coun- 

 tries. In the United States Arab horses are registered in " The 

 American Thoroughbred Studbook." The " General Studbook of 

 Great Britain " serves the same purpose in that country. In 1908 

 the Arabian Horse Club of America was incorporated, and Vol- 

 ume I of the "Arabian National Studbook "was published in 1913. 

 This contains the registration of one hundred and twenty-seven 

 Arabs and sixty-eight Americo-Arabs. In addition to registering 

 pure Arabs, this association registers, under certain conditions, 

 crosses with Thoroughbreds, trotters, " Kentucky saddle horses," 

 Morgans, and Clays.
