The gods have bestowed on man, indeed, the gift of teaching man his duty by means of speech and reasoning, but the horse, it is obvious, is not open to instruction by speech and reasoning. If you would have a horse learn to perform his duty, your best plan will be, whenever he does as you wish, to show him some kindness in return, and when he is disobedient to chastise him. This principle, though capable of being stated in a few words, is one which holds good throughout the whole of horsemanship. As, for instance, a horse will more readily take the bit, if each time he accepts it some good befalls him; or, again, he will leap ditches and spring up embankments and perform all the other feats incumbent on him, if he be led to associate obedience to the word of command with relaxation. (13) (13) Lit. "if every time he performs the word of command he is led to expect some relaxation." IX The topics hitherto considered have been: firstly, how to reduce the chance of being cheated in the purchase of a colt or full-grown horse; secondly, how to escape as much as possible the risk of injuring your purchase by mishandling; and lastly, how to succeed in turning out a horse possessed of all the qualities demanded by the cavalry soldier for the purposes of war. The time has come perhaps to add a few suggestions, in case the rider should be called upon to deal with an animal either unduly spirited or again unduly sluggish in disposition. The first point to recognise is, that temper of spirit in a horse takes the place of passion or anger in a man; and just as you may best escape exciting a man's ill-temper by avoiding harshness of speech and act, so you will best avoid enraging a spirited horse by not annoying him. Thus, from the first instant, in the act of mounting him, you should take pains to minimise the annoyance; and once on his back you should sit quiet for longer than the ordinary time, and so urge him forward by the gentlest signs possible; next, beginning at the slowest pace, gradually work him into a quicker step, but so gradually that he will find himself at full speed without noticing it. (1) Any sudden signal will bewilder a spirited horse, just as a man is bewildered by any sudden sight or sound or other experience. (I say one should be aware that any unexpected shock will produce disturbance in a horse.) (2) (1) Or, "so that the horse may insensibly fall into a gallop." (2) L.
