APPUI

APPUI, in the Manage, q. d. rest or stay upon the Hand; is the reciprocal Effort between the Horse’s Mouth and the Bridle-Hand; or the Sense of the Action of the Bridle in the Hand of the Horseman. See HEAD, BRIDLE, etc. A just Appui of the Hand, is the nice bearing up or stay of the Bridle; so that the Horse being awed by the Sensibility and Tenderness of his Mouth, dares not rest too much upon the Bit-Mouth, nor check or beat upon the Hand to withstand it. A dull, obtuse Appui, is when a Horse has a good Mouth, but his Tongue so thick, that the Bit cannot work, or bear upon the Bars; the Tongue not being so sensible as the Bars: though the like Effect is sometimes owing to the grossness of his Lips. A Horse is said to have no Appui, when he disowns the Bit-mouth; is too apprehensive of the Hand, and can’t bear the Bit. He is said to have too much Appui, when he rests or throws himself too much, too hardily upon the Bit. Horses designed for the Army ought to have a full Appui upon the Hand.
