Elizabeth Karr, The American Horsewoman
“ Rearing.—With the young horse, rearing is the last frantic effort to unseat his rider; an old rogue will sometimes resort to it, having found his rider timid and much alarmed at the movement. A lady should never ride a horse that has once reared dangerously, unless the action was occasioned by the injudicious use of too severe a curb-bit. A horse that has once reared without provocation will be very apt to do so again. The danger of this vice is, that the horse may fall backward and upon his rider. ”
