Chapter I: DEFINE the supple Trot to be that in which the Horse at every

Motion that he makes bends and plays all his Joints; that is to say, those of his Shoulders, his Knees and Feet, which no Colts or raw Horses can execute, who have not had their Limbs suppled by Exercise, and who always trot with a surprizing Stiffness and Aukwardness, and without the least Spring or Play in their Joints. The _even_ or _equal_ Trot, is that wherein the Horse makes all his Limbs and Joints move so equally and exactly, that his Legs never cover more Ground one than the other, nor at one Time more than another: To do this, the Horse must of necessity unite and collect all his Strength, and if I may be allowed the Expression, distribute it equally through all his Joints.

TO go from the _extended_ Trot, to the _supple_, you must gently, and by degrees, hold in your Horse; and when by Exercise he has attain'd sufficient Ease and Suppleness to manage his Limbs readily, you must insensibly hold him in, still more and more, and by degrees you will lead him to the _equal_ Trot.

THE Trot is the first Exercise to which a Horse is put; this is a necessary Lesson, but if given unskilfully it loses its End, and even does harm.

HORSES of a hot and fretful Temper have generally too great a Disposition to the _extended_ Trot; never abandon these Horses to their Will, hold them in, pacify them, moderate their Motion by retaining them judiciously, and their Limbs will grow supple; they will acquire at the same time that Union and Equality, which is so essentially necessary.

IF you have a Horse that is heavy, consider if this Heaviness or Stiffness of his Shoulders or Legs is owing to a Want of Strength, or of Suppleness; whether it proceeds from his having been exercised unskilfully, too much, or too little. If he is heavy, because the Motions of his Legs and Shoulders are naturally cold and sluggish, tho' at the same time his Limbs are good, and his Strength is only confin'd and shut up, if I may so say, a moderate but continual Exercise of the Trot will open and supple his Joints, and render the Action of his Shoulders and Legs more free and bold; hold him in the Hand, and support him in the Trot, but take care so to do it, as not to check or slacken his Pace: Aid him and drive him forward, while you support him; remember at the same time, that if he is loaded with a great Head, the Continuation of the Trot, will make his Apuy hard and dull, because he will by this means abandon himself still more, and weigh upon the Hand. All Horses that are inclined to be _remingue_, should be kept to the extended Trot; every Horse who has a Tendency to be _remingue_ is naturally disposed to collect all his Strength, and to unite himself; your only way with such Horses is to force them forward: In the Instant that he obeys, and goes freely on, retain him a little; yield your Hand immediately after, and you will find soon that the Horse of himself will bend his Joints, and go united and equally.

A HORSE of a sluggish and cold Disposition, which has nevertheless Strength and Bottom, should likewise be put to the extended Trot; as he grows animated, and begins to go free, keep him together by little and little, in order to lead him insensibly to the _supple_ Trot; but if while you keep him together, you perceive that he slackens his Action, and retains himself, give him the Aids briskly, and push him forward, keeping him nevertheless gently in Hand; by this means he will be taught to go freely and equally at the same time.

IF a Horse of a cold and sluggish Temper is weak in his Legs and Loins, you must manage him cautiously in working him in the Trot, or otherwise you will enervate and spoil him. Besides, in order to make the most of a Horse, who is not over strong, endeavour to give him Wind, by working him slowly, and at Intervals, and by increasing the Vigour of his Exercise by degrees; for you must remember that you ought always to dismiss your Horse, before he is spent and overcome with Fatigue. Never push your Lesson too far in hopes of suppling your Horse's Limbs by means of the Trot; instead of this you will falsify and harden his Apuy, which is a Case which happens but too frequently.

FARTHER, it is of Importance to remark, that you ought at no time, neither in the _extended_, _supple_ or _equal_ Trot, to confine your Horse in the Hand in Expectation of raising him, and fixing his Head in a proper Place; if his Apuy be full in the Hand, and the Action of his Trot should be check'd and restrain'd by the Power of his Bridle, his Bars would very soon grow callous, and his Mouth be harden'd and dead; if, on the contrary, he has a fine and sensible Mouth, this very Restraint would offend and make him uneasy. You must endeavour then, as has already been said, to give him by degrees, and insensibly, a true and just Apuy, to place his Head, and form his Mouth, by Stops and Half-stops; by sometimes moderating and restraining him with a gentle and light Hand, and yielding it to him immediately again; and by sometimes letting him trot without feeling the Bridle at all.

THERE is a Difference between Horses who are _heavy_ in the Hand, and such as endeavour to _force_ it. The first Sort lean and throw all their Weight upon the Hand, either as they happen to be weak, or too heavy and clumsy in their Fore-parts, or from having their Mouths too fleshy and gross, and consequently dull and insensible. The second _pull_ against the Hand, because their Bars are lean, hard, and generally round; and the first may be brought to go equal, and upon their Haunches, by means of the Trot and slow Gallop; and the other may be made light and active by Art, and by settling them well in their Trot, which will also give them Strength and Vigour. Horses of the first sort are generally sluggish, the other kind are for the most part impatient and disobedient, and upon that very account more dangerous and incorrigible.

THE only Proof, or rather the most certain Sign of your Horse's trotting well, is, that when he is in his Trot, and you begin to press him a little, he offers to Gallop.

AFTER having trotted your Horse sufficiently upon a strait Line, or directly forward, work him upon large Circles; but before you put him to this, walk him gently round the Circle, that he may comprehend and know the Ground he is to go over.--This being done, work him in the Trot; a Horse that is loaded before, and heavily made, will find more Pains and Difficulty in uniting his Strength, in order to be able to turn, than in going strait forward.--The Action of turning trys the Strength of his Reins, and employs his Memory and Attention, therefore let one Part of your Lessons be to trot them strait forward; finish them in the same Manner, observing that the Intervals between the Stops (which you should make very often) be long, or short, as you judge necessary: I say you should make frequent Stops, for they often serve as a Correction to Horses that abandon themselves, force the Hand, or bear too much upon it in their Trot.

THERE are some Horses who are supple in their Shoulders, but which nevertheless abandon themselves; this Fault is occasion'd by the Rider's having often held his Bridle-hand too tight and strict in working them upon large Circles: To remedy this, trot them upon one _Line_ or _Tread_, and very large; stop them often, keeping back your Body and outward Leg, in order to make them bend and play their Haunches.

THE principal Effects then of the Trot, are to make a Horse light and active, and to give him a just Apuy. In reality, in this Action he is always supported on one Side by one of his Fore-legs, and on the other by one of his Hind-legs: Now the fore and hind Parts being equally supported cross-wise, the Rider can't fail to supple and loosen his Limbs, and fix his Head; but if the Trot disposes and prepares the Spirits and Motions of a sinewy and active Horse for the justest Lessons, if it calls out and unfolds the Powers and Strength of the Animal, which before were buried and shut up, if I may use the Expression, in the Stiffness of his Joints and Limbs; if this first Exercise to which you put your Horse, is the Foundation of all the different Airs and Manages, it ought to be given in Proportion to the Strength and Vigour of the Horse.

TO judge of this you must go farther than mere outward Appearances. A Horse may be but weak in the Loins, and yet execute any Air, and accompany it with Vigour, as long as his Strength is united and intire; but if he becomes disunited, by having been work'd beyond his Ability in the Trot, he will then falter in his Air, and perform it without Vigour and Grace.

THERE are also some Horses, who are very strong in the Loins, but who are weak in their Limbs; these are apt to retain themselves, they bend and sink in their Trot, and go as if they were afraid of hurting their Shoulders, their Legs or Feet. This Irresolution proceeds only from a natural Sense they have of their Weakness.--This kind of Horses should not be too much exercised in the Trot, nor have sharp Correction; their Shoulders, Legs, or Hocks would be weaken'd and injur'd; so that learning in a little Time to hang back, and abandon themselves on the Apuy, they would never be able to furnish any Air with Vigour and Justness.

LET every Lesson then be weigh'd; the only Method by which Success can be insured, is the Discretion you shall use, in giving them in proportion to the Strength of the Horse, and from your Sagacity in deciding upon what Air or Manage is most proper for him; to which you must be directed by observing which seems most suited to his Inclination and Capacity.
