It is well also for the groom to have orders to remove the dung and litter
						daily to one and the same place. For by doing this he will get rid of it
						most easily and at the same time relieve the horse. The groom must also know about putting the muzzle on the horse when he takes
						him out to be groomed or to the rolling-place. In fact he must always put
						the muzzle on when he leads him anywhere without a bridle. The muzzle appears on several Greek vases. The Greek
							horse was given to biting. For the muzzle prevents him from
						biting without hampering his breathing; and moreover, when it is put on, it
						goes far towards preventing any propensity to mischief.
