The size, setting on, and motion of the ear, are important points. Ears rather small than large, placed not too far apart, erect and quick in motion, indicate both breeding and spirit; and if a horse is in the frequent habit of carrying one ear forward, and the other backward, and especially if he does so on a journey, he will generally possess both spirit and continuance. The stretching of the ears in contrary directions shows that he is attentive to every thing that is passing round him; and while he is doing this he cannot be much fatigued, or likely soon to become so. It has been remarked, that few horses sleep without pointing one ear forward and the other backward, in order that they may receive notice of the approach of objects in every direction. When horses or mules march in company at night, those in front direct their ears forward, those in the rear direct them backward, and those in the centre turn them laterally or across; the whole troop seeming thus to be actuated by one feeling which watches the general safety. The ear of the horse is one of the most beautiful parts about him, and by few things is the temper more surely indicated than by its motion. The ear is more intelligible even than the eye; and a person accustomed to the horse can tell, by the expressive motion of that organ, almost all that he thinks or means. When a horse lays his ears flat back on his neck, he most assuredly is meditating mischief, and the stander by should beware of his heels or his teeth. In play the ears will be laid back, but not so decidedly or so long. A quick change in their position, and more particularly the expression of the eye at the time, will distinguish between playfulness and vice.
