SCIENTIFIC BREEDING.

parents. The results of training must not be confused with 
heredity. Heredity—its nascent power has always been present, 
more or less, in the animal. Training in such lines as such 
faculties may exist, develops it, intensifies it; the more of each, 
the more there will be to expect as the combined result. There¬ 
fore who would attempt to train a Clyde except for draft, a hun¬ 
ter except for clearing obstacles, a trotter except for trotting. 
These laws govern heredity in the brute creation as persistently 
as they do in the human family, and the introduction of good, 
or the eradication of bad qualities will be found amenable to the 
breeder’s science through the potent agency selection. This 
forms the stepping-stone to scientific breeding, and until man 
has learned to take advantage of the hereditary tendencies toward 
good qualities, and works away from those that bring bad forms, 
bad temper, sterility, tendency to short life, and unpromising 
progeny, he is not worthy of being called a breeder of improved 
domestic animals. 
Selection .—A sire or dam should be rejected for any one 
really bad fault. The greatest strength of either is limited by 
his or her worst point. They are often selected because they 
possess one or more very good points.- This is a wrong principle 
in selecting. The selection of sire and dam should begin by re¬ 
jection for bad points. Brood-mares should be selected with as 
much critical scrutiny as stock horses, individual excellence is 
the criterion always in view, and embraces size, form, blood, 
color, performance, including ample and facile breathing ap¬ 
paratus. 
I firmly believe in a balanced structure for the greatest physi¬ 
cal capacity. Moreover, I contend that the undue development 
of one portion of the organism is plainly at the expense of its 
co-ordinate part. 
Applying these conclusions to the horse, I contend that when 
the horse is balanced, that is when he measures as high at the 
coupling as he does at the withers, and as long from the shoulder 
points to the posterior projection of the hips as he is high from 
the ground to the withers and the coupling, then the carcass is
