cannot be told in advance. Each horse has its peculiar sensibility, which must be discovered by experiment.
When the jambette both to the right and to the left is obtained by means of the snaffle, it is asked in the same way by the bit. When everything is thoroughly mastered with the trainer on foot, the latter mounts, and repeats the exercise by partial flexions of the neck, without using the whip. If, however, the horse does not understand when first mounted, it can be helped out by touches of the whip on shoulder or leg. But the whip should be eliminated as soon as possible.
Another way of obtaining the same jambette is to begin mounted. It is evident that, with the horse standing, a partial flexion of the neck to the right will shift on to the left fore leg the weight formerly carried by the right fore leg. This, therefore, being unloaded, tends to be raised from the ground. If, now, the trainer, at the first sign of this lifting, rewards the horse with caresses, the latter will very soon comprehend what is wanted; and, at the partial flexion of the neck, will hold up the right fore leg. (Figure 27.) The same means reversed operates to secure the elevation of the left fore leg.
During this practice on the jambettes, the rider's legs maintain the horse standing and straight, and prevent movement backwards. Here, then, are the principles which obtain the flexion at the scapulo-humeralis articulation.
