The above is, of course, the crudest of methods compared with the best School systems, but if you have taught Nelly her side steps (or pirouettes), as I have described them to you, or in other words have to a certain extent suppled her forehand and croup by the proper flexions, you can start in a more certain way. You must not expect to succeed at once. Success depends upon Nelly's intelligence, your own patience, and the delicate perceptions of both. I assume that you will have already taught Nelly to canter whenever you wish her to do so, though she may have been selecting her own lead. Now, you can, of course, see, when you want her to canter, that if you keep her head straight with the reins and press upon her near flank with your leg, she will throw her croup away from your leg, and be for the moment out of the true line of advance. This is bad for the walk or the trot, but just what you want to induce her to start the canter with the off shoulder leading. For if you can keep her in this position until she takes the canter, she will be more apt to lead off with her right shoulder, because the forcing of her croup to the right has also pushed this shoulder in advance of the other. If at the same time she is traveling along a slope which runs up from her right, say the left side of the road, or on a circle turning to the right, she will be all the more apt to do this. You can aid her also by a little marked play with the right rein, which will tend to enliven that side, and by giving it increased action, aid in bringing it forward, even if not done with entire expertness.
A number of English writers state that the proper indication for the lead with the right foot is a tap of the whip on the right side, but this appears to be lacking in good theory, and might prove very confusing to a horse, despite the fact that the animal can be made to learn anything as an indication. A tap of the whip under the right elbow would be more consistent with the horse's action, although it is quite possible, as a feat, to teach a horse to lead with the off shoulder by pulling his off ear, or his tail, for the matter of that. But indications are best when they tally with a sound theory of the horse's motions.
Reverse causes will induce Nelly to lead with the left shoulder. Not, of course, at once. For though she will do it in a circle or figure eight, on the road she may still be often confused. It requires much time and practice to make her perfect. But once Nelly catches the idea, you can surely succeed in impressing it on her for good and all, and though she will blunder often enough, she will in the end learn it thoroughly.
When you start out to make Nelly lead off with one shoulder, be sure you accomplish your object. If she leads off with the other, stop her at once, and try again. Always succeed with a horse in what you undertake. If you cannot, on any given day, make Nelly lead right, do not let her canter at all, but keep her on a trot or a walk. It requires a number of successful trials to make it plain to the intelligence of a horse that he has done what you want, and is to do it again on similar indications. It is, therefore, well for him not to have to learn too many new lessons at once.
XLI.
To change lead in motion is harder for the horse and rider both to learn, and there is no better test of a well-trained horse than an immediate and balanced change of lead on call. A canter is a gait somewhat similar to the gallop, though the feet move and come down in different progression. But at certain times one or more of the four feet are successively sustaining the weight, and there is an interval when the horse is unsupported in the air, or has only one hind foot upon the ground. It is this last period which the horse chooses in which to change his lead. Now, suppose you are cantering with Nelly's right shoulder leading, and want her to change to the left. If you press upon her right flank with your leg, she will want to shift her croup to the left. This will incline her naturally to turn her head to the right, which inclination you must counteract with as little motion as possible of the reins. Nelly will thus find that she is cantering uncomfortably to herself, and if you will keep along in this way for a few strides, she will very likely shift to her left lead, because the constraint of your leg and the bit are irksome while she continues to lead with the right, and she will try what she can do to get rid of the restraint. She certainly will change after a while, particularly if aided by the circle or slope, even if she does it because she does not know what else to do. And by rousing or lightening the left shoulder by a play of the left rein you will materially aid the change. So soon as she has changed, reward her by a few words, and canter along on the new lead.
The reverse accomplishes a similar result. It will probably take you many weeks to bring about all this. If you do it in a few weeks, you will succeed far beyond the average. But the process of teaching an intelligent horse, if you are patient, is as pleasant as the result of the lessons is agreeable, after they have had their due effect.
A horse should be so well trained as to be ready to turn with a "false" lead if you ask him to do so. Left to himself, he should take the proper lead at the moment of turning. But he must obey you to the extent of doing what he would otherwise not do, and should properly not do, if you give him the indication. And this without becoming confused, so as to fail to do the proper thing on the next occasion.
Though I by no means hold up Patroclus to-day as a model performer of School-paces, which I am perhaps too lazy to keep him as perfect in as I ought to do, the results of good training still remain. I sometimes, when out of sight, canter him quite a stretch, say quarter of a mile, changing lead, first every fourth stride, then every third stride, then every second, in regular rhythmic succession. If Patroclus fails to do this feat with exactness, I can always recognize my own error in too late an indication, rather than his in obeying it. It is possible to canter him very slowly with a change of lead at every stride, but such work is very exhausting to a horse, and I have not often done it. This latter feat must be done so slowly that the gait is properly not a canter; but Patroclus can perform the true canter, and change at every second step readily for several hundred yards.
