used. If the rider's inward leg does not instantly receive the change of leg which his outward leg sends it, the horse will naturally put his croup sideways. Under these conditions, the changes of leg are never regular or well done. And, as it always takes two or three strides to straighten a horse, it will be impossible to do these changes with short intervals between them.

On the outside the evil is less, because the wall prevents the haunches from being brought too much round.

When the changes are correctly done with both legs to the right and to the left, and especially in the corners of the school, I only then begin to regulate them, which it is impossible to do before being certain that the horse will change each time, and at the moment I want him.

At first I content myself with getting him to change in every eight or ten strides of the canter, and I demand only a single change on each leg. If he becomes excited, he should be stopped and practised again at starting.

To be on good terms with the horse, it is necessary to count the strides of the canter. For example, when going to the right, with the horse cantering with the off fore, I count 1, 2, 3, 4, 5, 6, each number marking a stride. At the sixth I make him change, and then I make him do the same work with the near fore leading. If the horse does correctly the two changes I have asked, I stop him and pat him on the neck. I then begin again by requiring him to do only a single change on each leg.

At the end of a few days, when I feel that the horse does this work freely, I demand four and then six changes, always at the sixth stride. As long as the horse does this work in a tranquil frame of mind, I gradually increase the number of changes at the sixth stride, or, as it is said, at the sixth " time," but without over-doing it.

If the horse gets excited I stop him, but I do not pat him,
