which did it more or less brilliantly, according to their degrees of energy.

It is very difficult to explain how to teach the see-saw piaffer, but I will try to do so.

It will at first be seen that this movement should not be required from any horse, unless he can do the slow and high piaffer. As such an animal, when doing this exercise, has extreme mobility, the slightest feeling on the reins will be sufficient to make him bring a leg a little back, in the same way that the smallest increase in the pressure of the spur will cause him to bring a leg a little forward.

Being at the piaffer, we ought, by means of the legs, to make the horse bring his near hind under him where he puts it down. The right diagonal being in support, the near fore—which, under the same action of the legs of the rider, has been carried forward at the moment when the near hind is placed under the animal's body—remains held up in the air, the knee bent, and the off hind also in the air (Fig. 66). Immediately the hand ought to act, in order to bring back the near fore, which is about to be placed behind the off fore, and which forms, along with the off hind, the left diagonal support ; whilst the near hind, in its turn, does a time in the air, and the off fore performs its movement in the piaffer.^[1] (Fig. 67.)

We can see that in the forward movement the near hind is placed in front of the off hind (Fig. 66), and that in the retrograde movement the near fore is placed behind the off fore (Fig. 67). This is the cause of the see-saw action from the rear to the front.

If the reader understands my explanations he will observe
