 through the English thorough-bred, we have got at home 

 in our runners and trotters and saddle-beasts, and by a 

 principle of natural selection in the bronco. And this same 

 quality we Occidentals, by more intelligent and careful 

 breeding and trainino^ and racing than the horse has ever 

 undergone elsewhere, may fairly claim to have improved.
