THE HORSE, ASS, AND MULE 



The conformation of the pacing horse often shows a steepness 

 of croup and curving of hocks which appear to be more or less 

 associated with the gait, though not necessarily so. Some of the 

 most famous pacers in American racing history have had this 

 peculiar conformation which, to say the least, is not beautiful. 



The pacing standard, as established by the American Trotting 

 Register Association, is the same as the existing trotting stand- 

 ard. Except that the word "pacer" is substituted for the word 

 "trotter," the word " pacing" for the word "trotting," and the

speed standard 2.25 for 2.30, the first five paragraphs of official 

 trotting and pacing standards are alike. The pacing standard, 

 however, has a sixth paragraph, which is as follows : 



6. The progeny of a registered standard trotting horse out of a registered 

 standard pacing mare, or of a registered standard pacing horse out of a 

 registered trotting mare. 



This last paragraph brings out the interesting point in an offi- 

 cial way, that the result of the union of a pacer and trotter may 

 create a standard-bred pacer.
