Chapter I: HAVE thus explained the different Positions and Motions of the Hand;

let me shew now in a few Words the Effects which they produce.

THE Horseman's Hand directs the Reins; the Reins operate upon the Branches of the Bit; the Branches upon the Mouth-piece and the Curb; the Mouth-piece operates upon the Bars, and the Curb upon the Beard of the Horse.

THE Right Rein guides the Horse to the Left; the Left Rein to the Right. Would you go to the Right, you pass to the fourth Position of the Hand, that is, you carry and turn your Nails to the Right; now in carrying thus your Nails to the Right, and reversing your Hand in such a manner, that your Thumb point to the Left, and your Little-finger being raised turns to the Right, you by this means shorten your Left Rein; it is this Left therefore that turns and guides the Horse to the Right: Would you go to the Left, pass to the fifth Position, you will carry the Back of your Hand to the Left, so that your Nails will be turned down a little, your Thumb will be to the Right, and the Little-finger to the Left; this will shorten the right Rein, and the right Rein determines your Horse to the Left.
