ELEMENTS OF HIPPOLOGY. 61 The two ridge-like'poi-tions of the bone of the lower jaw be- tween the molars and the tushes are called the bars, and form the points of application for the bit. As regards their action on the horse's jaw, bits are classified as bar, snaffle, and curb bits. A bar bit is an unbroken bit that acts, without lever- age, directly on the horse's jaw, as in Figure 43. The bar bit is supported partly on the bars of the horse's jaw and partly on his tongue. This is tough, leathery, and insensi- tive. When the pressure of the bar bit on the horse's jaw becomes painful to the bars, he relieves the pain by thrust- ing his tongue further under the bit, thereby lifting it from the bars and transferring the pressure to his tongue. To nullify this action of the tongue and still have a bit that is not, with proper use, exces- -The Lower Jaw-Bone sively severe, a hinge is intro- duced in the center of the bar bit, and the resulting bit is called a snaflie bit. By pulling on the reins of a snafHe bit, a pincer action is de- veloped by the closing of the angle between the halves of the mouthpiece. This raises the hinge, lifting the mouthpiece off the tongue, and applies pressure to the bars in a way impossible of relief by the tongue. Digitized by Microsoft®.
