There is another trot which is called the "swimmer," in which the horse ought to trot as fast as he can, while indicating with his fore legs a time of suspension in the air. But, as the speed is great, the period of suspension is much less marked than in the Spanish trot. I do not think that this is a school movement. A horse which trots well with his shoulders and knees will do it naturally. I content myself with merely mentioning it.

SERPENTINE AT THE TROT.

This movement consists in making a horse take four side steps to the left and four to the right at a well-collected trot. During the whole time the horse ought to go on two tracks, the forehand gaining a little more ground at the side to which the animal is proceeding, so as to prevent the haunches from going in front of the shoulders.

This movement appears simple, but it is very difficult to do correctly. We can quickly see that there is only a very short interval to put the horse back from one diagonal to the other gently and smoothly. All the merit and all the difficulty of this exercise consist in taking exactly four steps to each side. If the animal sometimes takes three, and sometimes five, there is no difficulty, merit, or interest.

CANTER ON THREE LEGS.

We can make a horse canter on three legs, in which case the three first times of the canter are done in a rassembléd canter (in four times), and the fourth time is done in the air. If, for example, we are cantering to the right, the off fore should be held up, without touching the ground.

Few horses can do in a brilliant manner the canter on three legs. Many can succeed in doing it ; but only a very energetic animal can hold his leg well extended in the air, without its touching the ground, during the whole period of the movement,
