82 A TREATISE ON HORSE-BREEDING.

 number, perhaps, of rams and boars. 



It is quite reasonable to suppose that a mate-

 gans as upon the motor apparatus; and upon 

 cattle, sheep, and swine as upon horses. And 

 breeders should not be in too great haste to 

 declare an animal a non-breeder under such 

 circumstances. Ample time should be given 

 for thorough acclimatization in all cases of this 

 nature. 



CONTROLLING THE SEX. 



It has been said that there is nothing new 

 under the sun, and that each succeeding gener- 

 ation spends most of its time in shoveling over 

 the same earth that has been examined in vain 

 by its predecessors in search of hidden treasures. 

 Theories that have been advanced, investigated
