H. L. de Bussigny, Hand-book for Horsewomen
“ The school, on the other hand, is the nursery of cavalry; and, for the army, speed is not so much needed as uniformity of movement and general handiness in rapid and complicated evolutions. Hence the great military riders of the continent have aimed at bringing the horse under complete control, and to this end they have applied themselves to the problem of mastering his hind legs, which are the propelling power, and therefore the seat of resistance. And it is precisely this subjection that horses dislike and try to evade with the utmost persistence. ”
