The strongest Aid is that of pinching with the Spur; the next in degree, is applying the Calf of the Leg; pressing with the Knees is the third, and leaning upon the Stirrup is the last and least; but if these Aids are given injudiciously, they will have no Effect. They must accompany and keep Pace with the Hand; for it is the just Correspondence between the Heel and Hand, in which the Truth and Delicacy of the Art consists; and without this Agreement there can be no riding.
It is the Foundation of all Justness; it constitutes and directs the Cadence, Measure and Harmony of all the Airs; it is the Soul of Delicacy, Brilliancy and Truth in riding; and as a Person who plays upon a musical Instrument adapts and suits his two Hands equally to the Instrument, so the Man who works a Horse ought to make his Hands and Legs accord exactly together. I say his Hands and Legs should accord and answer one to the other with the strictest Exactness, because the nicest and most subtle Effects of the Bridle proceed entirely from this Agreement; and however fine and nice a Touch a Horseman may be endued with, if the Times of aiding with the Legs are broken and imperfect, he never can have a good Hand; because it is evident that a good Hand is not the Offspring only of a firm and good Seat, but owing likewise to the Proportion and Harmony of all the Aids together. I understand by the Harmony and Agreement of the Aids, the Art of knowing how to seize the Moment in which they are to be given, and of giving them equally and in a due Degree, as well as of measuring and comparing the Action of the Hand and Legs together; by which both these Parts being made to act together, and in time, will create and call out, as it were, those Cadences and Equalities of Time, of which the finest Airs are compos'd; Measures and Cadences which it is not possible to describe, but which every Horseman ought to comprehend, attend to, and feel. If I want to make my Horse go forward, I yield my Hand to him, and at the same time close my Legs; the Hand ceasing to confine, and the Legs driving on his hinder Parts, the Horse obeys. I have a mind to stop him, I hold him in, and approach my Legs to his Sides gently, in order to proportion my Aids to what I ask him to do; for I would not have it felt more than just to make him stop upon his Haunches.
I want to turn him to the Left, I carry my Hand to the Left, and support him at the same time; that is to say, I approach my Left-leg, my Hand then guides the Horse to the Left, and my Leg, which operates at the same time, helps him to turn; because by driving his Croupe to the Right, his Shoulder is enabled to turn with more Ease. I want to go to the Right, I carry my Hand to the Right, and I support him with my Right-hand, my Leg determining his Croupe to the Left, facilitates the Action of the Shoulder which my Hand had turned to the Right.
I would make a Change to the Right, my Left-rein directs the Horse, and my Left-leg at the same time confines his Croupe, so that it can't escape, but must follow the Shoulders.—I would change Hands again to the Left, my Right-rein then guides the Horse, and my Right-leg does just the same as my Left-leg did in going to the Right.—I undertake to work the Shoulder and Croupe at the same time; for this Purpose I carry my Hand out.—The inner Rein acts, and the outward Leg of the Horse is press'd, either by this Rein, or by my outward Leg, so that the outward Rein operates upon the Shoulder, and the inner Rein with my outward Leg directs the Croupe.—I put my Horse to Curvets.—I aid him with my outward Rein, and if he is not enough upon his Haunches, my Legs, accompanied with the inner Rein, aid me to put him more upon them; if he turns his Croupe out, I aid and support him with my outward Leg; if he flings it in too much, I confine him with my inner Leg.
I put him to make Curvets sideways, my outward Rein brings his outward Shoulder in, because the outward Shoulder being brought in, his Croupe is left at liberty; but if I have occasion I use my inner Rein, and if his Croupe is not sufficiently confin'd, I support it with my outward Leg.—Again, I put him to make Curvets backwards, I use then my outward Rein, and keep my Hand near my Body. At each Cadence that the Horse makes, I make him feel a Time; one, and every time he comes to the Ground, I receive and catch him as it were in my Hand; but these Times ought not to be distant above an Inch or two at the most; I then ease my Legs to him, which nevertheless I approach insensibly every time he rises. Thus by making my Hands and Legs act together, I learn not only to work a Horse with Justness and Precision, but even to dress him to all the Airs; which I shall speak of distinctly and more at large.
As to the rest, be it remember'd, that it is not alone sufficient to know how to unite your Aids, and to proportion them, as well as the Corrections, to the Motions and the Faults in the Horse's Air, which you would remedy; but whenever you are to make use of them, you must consider likewise if they are suitable and adapted to the Nature of the Horse; for otherwise they will not only prove ineffectual, but be the Occasion even of many Disorders.

Of the Passage.
The Passage is the Key which opens to us all the Justness of the Art of riding, and is the only Means of adjusting and regulating Horses in all sorts of Airs; because in this Action you may work them slowly, and teach them all the Knowledge of the Leg and Hand, as it were insensibly, and without running any risque of disgusting them, so as to make them rebel.—There are many sorts of the Passage: In that which is derived from the Trot, the Action of the Horse's Legs is the same as in the Trot; the Passage is only distinguish'd from the Trot, which is the Foundation of it, by the extreme Union of the Horse, and by his keeping his Legs longer in the Air, and lifting them both equally high, and being neither so quick nor violent as in the Action of the Trot.
In the Passage which is founded on the Walk, the Action of the Horse is the same as in the Trot, and of consequence the same as in the Walk; with this Difference, that the Horse lifts his Fore-feet a good deal higher than his Hind-feet, that he marks a certain Time or Interval sufficiently long between the Motion of each Leg; his Action being much more together and short, and more distinct and slow than the ordinary Walk, and not so extended as in the Trot, in such a manner that he is, as it were, kept together and supported under himself.
