THE POLLED SHORTHORN 251 



The promotion of Polled Shorthorn interests is officially super- 

 vised by the American Polled Shorthorn Breeders' Association, 

 organized at Chicago in 1889 as the American Polled Durham 

 Breeders' Association. However, on July 11, 1919, the associa- 

 tion in session in Chicago substituted '" Shorthorn " for Durham. 

 Seven volumes of the herdbook have since been published up 

 to 1919. It is to be noted in this connection that breeders are 

 seeking to produce mainly animals that are eligible to registration 

 in the "American Shorthorn Herdbook." The greater the per- 

 centage of "double standard" Polled Shorthorns produced, the 

 less the necessity of maintaining an independent herdbook for 

 the polled cattle of the breed.
