It is an interesting fact that the Hambletonians, 
the Mambrino Chiefs, and the Clays all have a hall- 
mark, so to say, of their own, not found of course in 
every individual belonging to their blood, but still 
extremely common. In the Hambletonian family this 
is a white hind foot, mottled with black; in the 
Mambrino Chief family, especially in the Mambrino 
Patchen branch, it is one hind leg gray from foot to 
hock; in the Clays, it is a few gray hairs at the root 
of the tail.

the main sources of trotting speed,—namely, the 
Messenger strain as exhibited especially in the Ham-

the Hambletonian family, and the Grand Bashaw or 
Barb strain preserved in the Clays, —I come to the 
fourth main source of trotting speed, namely, the 
Morgans, a New England breed.
