On the Cavalry Commander (5.4-5.5)

He should tie up the horse at a place above the head, because when anything irritates his face, the horse instinctively tries to get rid of it by tossing his head upwards; and if he is tied thus he loosens the halter instead of breaking it by tossing up his head.

In rubbing the horse down, the man should start at the head and mane; for if the upper parts are not clean, it is idle to clean his lower parts. Next, going over the rest of his body, he should make the hair stand up with all the dressing instruments,[*] and get the dust out by rubbing him the way the hair lies. But he should not touch the hair on the backbone with any instrument; he should rub and smooth it down with the hands the way it naturally grows; for so he will be least likely to injure the rider’s seat.
