Prevailing Opinion of Horsemen.

It is a prevailing opinion among horsemen generally, that the sense of smell is the governing sense of the horse. And Faucher, as well as others, have, with that view, got up receipts of strong smelling oils, etc., to tame the horse, sometimes using the chesnut of his leg, which they dry, grind into powder and blow into his nostrils. Sometimes using the oil of rhodium, organnnum, etc.; that are noted for their strong smell. And sometimes they scent the hands with the sweat from under the arm, or blow their breath into his nostrils, etc., etc. All of which, as far as the scent goes have no effect whatever in gentling the horse, or conveying any idea to his mind; though the works that accompany these efforts handling him, touching him about the nose and head, and patting him, as they direct you should, after administering the articles, may have a very great effect, which they mistake to be the effect of the ingredients used. And Faucher, in his work entitled, "The Arabian art of taming Horses," page 17, tells us how to accustom a horse to a robe, by administering certain articles to his nose; and goes on to say, that these articles must first be applied to the horse's nose before you attempt to break him, in order to operate successfully.
