162 THE BREEDS OF LIVE-STOCK 
polo mount seems to be one that is three-quarters Thor- 
oughbred. As laid down by E. D. Miller in his book, 
“ Modern Polo,” the polo mount should be a Thoroughbred 
out of a mare by a Thoroughbred; that is, it should 
be three-quarters Thoroughbred race horse. 
In America, the mounts used to play the game are secured 
chiefly from the West, and the demand for mounts here is 
not yet anything like what it is in England. The supply 
is entirely inadequate to meet the demand, and polo 
mounts are sought for the English market not only in 
America, including Canada, Mexico and Argentina, but 
in every corner of the horse-breeding world, — Egypt, 
Syria, Barbary, Russia, France, Persia and South Africa. 
While the mounts thus secured are not equal in speed, 
endurance or courage to, the English or American race 
horse, the best, when trained and fitted, command very 
high prices. The prices may be said to range anywhere 
from $300 to $3000. In fact, there is no limit to the 
price, as those who play the game are, as a rule, men of 
means to whom a really good animal is cheap at any 
price. The exacting qualifications, however, make first- 
class polo mounts rare. 
Breeding polo mounts at present is somewhat of an 
experiment and presents many difficulties, the chief 
being the limit of height. All breeding of horses goes 
to prove the impossibility of insuring the progeny of any 
given size. In America, the western pony mare is bred 
to small Thoroughbred stallions, and in a very few cases 
to Arabian horses. In England, to keep the size down, 
pure pony blood as foundation stock is being used to 
found a breed of polo mounts, the fillies being bred back 
to stallions of the same breed as their sires, the produce 
of which will be three-quarters Thoroughbred. The
