The Pure-bred 337 
rules, the unregistered dams will have no number, al- 
though their names will usually appear. When the 
animals have been registered in foreign countries, the 
foreign registration number will always accompany the 
American number, but will be in parenthesis. Canadian 
numbers will be put in brackets. In addition to such 
certificates of registration, the secretary of the association 
publishes all such pedigrees in a book, which is called a 
stud-book. The volumes of such books are published 
as often as there are sufficient number of pedigrees to 
warrant it. With our leading breeds of horses, there are 
from ten to twenty volumes published. 
Recognized associations. 
In the stallion business there have been many fakes 
in pedigrees or certificates of registry. This has led to 
a closer study of the breed associations to determine 
which are reliable in their methods of recording and which 
have rules stringent enough that the animals registered 
may be considered pure-bred. The larger number of 
the stallion registration laws allow pure-bred licenses 
to animals registered in the following associations. Ani- 
mals recorded in other associations are considered of 
doubtful breeding. 
American Association of Importers and Breeders of Belgian 
Draft Horses, Wabash, Indiana. 
American Breeders and Importers Percheron Registry, Plain- 
field, Ohio.
