With certain light and well-shaped horses, I have obtained changes of the leg at the canter almost immediately ; although the majority of horses generally require six months to learn to do it properly. The same can be said of everything in riding.

SHOULDER-IN AT THE CANTER.

I have put demi-voltes at the canter into ordinary riding, because one might require, when hacking, to take a few steps at the canter on two tracks, in a more or less correct manner, in order to get out of somebody's way. I will now take up the study of the canter in high-school riding.

When the horse does demi-voltes correctly at the canter, I try by shoulder-in work at the canter, to bring his shoulders away from the wall. For this, the horse has been admirably prepared by work on two tracks at the school walk, and further by demi-voltes at the canter.

I start my horse at a canter on the near fore, and being on the right track, I keep him on it for a few strides. I then carry my hands to the right, in order to bring his shoulders away from the wall, but only about a yard. I work my right leg strongly, in order to carry the haunches from the right to the left ; whilst my left leg receives, so to speak, the haunches, which my right leg has just sent it, and throws the impulse on the hand. In fact, the left leg presses the horse forward, and thus prevents him from getting behind his bridle. It also regulates the pace by preventing the animal from sidling off to the left. If there is nothing to check the speed of the pace to the side, whether at the walk, trot, or canter, the horse will fatally regulate his pace, and will rush to the side in order to get out of hand, that is to say, he will no longer keep on two tracks. It is therefore necessary, in order for the movement to be regular, that the rider can regulate the cadence at all paces, and that he always keeps his legs close to the sides of
