THE HORSE, ASS, AND MULE 



The speed of the trotter is the main factor influencing values, 

 and the speed record of an animal, or its relationship to such, 

 will essentially affect its selling price. As might be expected, 

 foals occasionally change hands at large prices, based on the 

 pedigree and speed records therein. The speed of the trotter 

 has been constantly improved, until the end of 1904 saw records 

 that would not have been thought possible by persons living a 

 generation ago. All of the standard racing records have been 

 materially changed during the nineteenth century. The following 

 statement shows how this record has been lowered between 18 10 

 and 1904, representing horses in harness and not under saddle.
