174 THE HORSE, ASS, AND MULE 



Many of these ponies, with all their good qualities, are most 

 uncertain of temper and may prove very irritating when least 

 expected. Curtis makes the mustang and Indian pony of dif- 

 ferent breeding, though they range the same in height (12 to 14 

 hands), weigh much the same (600 to 850 pounds), and have 

 much the same color. The Indian pony is given as more blocky 

 than the mustang, the cannons are wider, and the pasterns 

 more upright. 



The Polo pony is not a breed, but represents a type and size 

 suitable to be used in playing polo. For this purpose anything 

 possessing the necessary speed, activity, endurance, and intelli- 

 gence will do. The maximum height allowed by the American 

 Polo Association is 14^ hands. Small Thoroughbreds, Western 

 ponies, and cross, or half-breds, are popular.
