only under which condition is this exercise interesting and brilliant.

If the reader has attentively followed my explanations, he will know that accustoming the horse to the pressure of the legs prepares him for this school movement, which is very difficult for the animal to understand and do. In fact, up to this, he has learned only to raise, extend, and place his legs on the ground, one after the other ; but now he is required to extend only one leg, and to keep it in that position.

The canter with the off fore in the air has only three beats on the ground—the first made by the near hind, the second by the off hind, and the third by the near fore. The fourth time is marked in the air by the off fore, which is fully extended and kept as high as possible.

Before putting a horse to this work, we should wait until he is perfectly broken, and until he will offer no resistance. At this time, I have at my disposal two movements which have been separately learned, namely, the ordinary canter to the right, and the extension of the off fore. From the combination of these two exercises, in which my left leg is my chief helper, I obtain the canter to the right on three legs.

It seems, in theory, that I ought to easily obtain the canter to the right on three legs, by vigorously using the left spur. But, in practice, this is not so simple ; because, having put my horse into the canter, the use of the left spur will do no good ; for it will make him bring his haunches to the right, or get away, but it will not make him extend his off fore.

We should therefore canter the horse to the right, and, having halted him, make him extend his off fore. When he has done this, we should pat him on the neck, and then begin again several times.

When the horse extends the leg without difficulty during the halt, we should make him go through the same performance, during a shorter halt.
