He should never force, alter, or lose the true Apuy, either in raising, supporting, holding in, or driving forward his Horse.—His Head should be not only firm and steady, but it is indispensably necessary that his Seat should be exactly strait and just; for since the Arm is an Appendix of the Body, it is certain that if the Motions of the Horse shake or disorder the Body of the Rider, the Bridle-hand must inevitably be shook, and consequently the true Apuy destroy'd.
In this Attitude then approach the Calves of your Legs, support and hold your Horse up with your Hand, and when the Fore-part is at its due Height, aid with the Switch upon the Croupe.
If your Horse rises before, keep your Body strait and firm; if he lifts or tosses up his Croupe, or yerks out, fling your Shoulders back without turning your Head to one side or the other, continuing the Action of the Hand that holds the Switch.
Remember that all the Motions of your Body should be so neat and fine as to be imperceptible; as to what is the most graceful Action for the Switch-hand, that over the Shoulder is thought the best; but then this Shoulder must not be more back than the other; and care must be taken that the Motion be quick and neat, and that the Horse do not see it so plainly as to be alarm'd.
I have said, that when the Horse made his Leaps too long and extended, you should then aid with your Hand-spur; and for this Reason, because the Hand-spur will make the Horse raise his Croupe without advancing, as the Effect of the Switch will be to raise the Croupe, and drive the Horse forward at the same time; it should therefore be used to such Horses as retain themselves.
Remember that you should never be extreme with your Horse, and work him beyond his Strength and Ability; indeed one should never ask of a Horse above half of what he can do; for if you work him till he grows languid and tired, and his Strength and Wind fail him, you will be compell'd to give your Aids roughly and openly; and when that happens, neither the Rider or the Horse can appear with Brilliancy and Grace.
THE END.
