A man who wants to make a bow carry a very long way must be standing entirely on one foot and raising the other so far from the foot he stands on as to afford the requisite counterpoise to his body which is thrown forward on the first foot. And he must not hold his arm fully extended, and in order that he may be more able to bear the strain he must hold a piece of wood which as used in crossbows extends from the hand to the breast, and when he wishes to shoot he should suddenly leap forward and at the same instant extend his arm with the bow and release the cord.
