tell me, why this strong young colt, foaled in some peaceful valley of vermont, far removed from all beasts of prey—why is it that upon the sunniest day, if you but shake a fresh buffalo robe behind him, so that he cannot even see it, but only smells its wild animal muskiness—why will he start, snort, and with bursting eyes paw the ground in phrensies of affright? there is no remembrance in him of any gorings of wild creatures in his green northern home, so that the strange muskiness he smells cannot recall to him anything associated with the experience of former perils; for what knows he, this new england colt, of the black bisons of distant oregon?
