On the Cavalry Commander (4.5-5.1)

When he is being rubbed down and teased with flies he is bound to use his hoofs in the same way as when he walks. The frogs also are hardened by stones scattered in this way.

The same care must be taken to make his mouth tender as to harden his hoofs. This is done by the same methods as are employed to soften human flesh.

It is a mark of a good horseman, in our opinion, to see that his groom, like himself, is instructed in the way in which he should treat the horse.

First then the man ought to know that he should never make the knot in the halter at the point where the headstall is put on. For if the halter is not easy about the ears, the horse will often rub his head against the manger and may often get sores in consequence. Now if there are sore places thereabouts the horse is bound to be restive both when he is bridled and when he is rubbed down.
