some extent by nature at the trot; while the horse with hock placed 
high—that is, with long hind cannon—is a galloper from impulse. Do 
not understand by this that a horse with fairly long hind cannon can 
not carry trotting speed — far from it; many a horse that lacks the 
best essentials for perfection at the trotting gait, by long and careful 
training, proper balancing by shoes and toe weights, and restraint by 
straps and hobbles, may be trained to trot at speed; but the time is 
past when trotting interests can be sustained by training and manipu¬ 
lation only. The impulse to trot — the “instinct” if you will — must 
be controlled in great degree by conformation of the parts concerned, 
combined with mental aptitude. Both these essentials for the future 
trotter may be fixed by well known laws of breeding and become es¬ 
tablished features of the future trotting breed.
