The Legs serve for two Purposes; they may be used as Aids, or Corrections, to the Animal. They should then be kept near the Sides of the Horse, and in a Line with the Man's Body; for being near the Part of the Horse's Body where his Feeling is most delicate, they are ready to do their Office in the Instant they are wanted. Moreover, as they are an Appendix of the Thighs, if the Thigh is upon its Flat in the Saddle, they will, by a necessary Consequence, be turned just as they ought, and will infallibly give the same Turn to the Feet; because the Feet depend upon them, as they depend upon the Thighs.
The Toe should be held a little higher than the Heel, for the lower the Toe is, the nearer the Heel will be to the Sides of the Horse, and must be in danger of touching his Flank. Many Persons, notwithstanding, when they raise their Toe, bend and twist their Ankle, as if they were lame in that Part. The Reason of this is very plain; it is because they make use of the Muscles in their Legs and Thighs; whereas, they should employ only the Joint of the Foot for this Purpose; a Joint, given by Nature to facilitate all the Motions of the Foot, and to enable it to turn to the Right or Left, upwards or downwards.
Such is, in short, the mechanical Disposition of all the Parts of the Horseman's Body. I will enlarge no further upon a Subject treated on already so amply by every Writer; as it is needless to write what has been already handled. I have had no other Design in this Chapter, than to give an Idea of the Correspondence that there is between all the Parts of the Body, because it is only by a just Knowledge of this mutual Relation of all the different Parts, that we can be enabled to prescribe Rules for giving that true and natural Seat, which is not only the Principle of Justness, but likewise the Foundation of all Grace in the Horseman.
CHAP. II.
Of the Hand, and its Effects.
The Knowledge of the different Characters, and the different Nature of Horses, together with the Vices, and Imperfections, as well as the exact and just Proportions of the Parts of a Horse's Body, is the Foundation upon which is built the Theory of our Art; but this Theory will be unnecessary and even useless, it we are not able likewise to carry it into Execution.
This depends chiefly upon the Goodness and Quickness of Feeling in the Hand, a Delicacy which Nature alone can give, and which she does not always bestow. The first Sensation of the Hand consists in a greater or less Degree of Fineness in the Touch or Feeling; all of us are equally furnished with Nerves, from which we have the Sense of Feeling, but as this Sense is much more subtle and quick in some Persons than in others, it is impossible to give a precise Definition of the exact Degree of Feeling in the Hand, which ought to communicate and answer to the same Degree of Feeling in the Horse's Mouth; because there is as much difference in the Degrees of Feeling in Men, as there is in the Mouths of Horses.
I suppose then a Man, who is not only capable to judge of the Qualities of a Horse's Mouth from a Knowledge of the Theory, but who has likewise by Nature that Fineness of Touch, which helps to form a good Hand; let us see then what the Rules are that we must follow, in order to make it perfect, and by which we must direct all its Operations.
A horse can move four different Ways, he can advance, go back, turn to the Right, and to the Left; but he can never make these different Motions, unless the Hand of the Rider permits him by making four other Motions which answer to them: So that there are five different Positions for the Hand.
The first is that general Position, from which proceed, and indeed ought to proceed, the other four.
