The loose eye. The square-cut eye of the regimental bit greatly impedes its action, besides cutting the leather of the headstall; to remedy this, about a quarter of a century ago, I placed on the bit of the 2nd Life Guards what has since received the name of “the loose eye,” and I am proud to see it still where I placed it. It was not intended for common bits; the round eye and the snap hook give them perfect freedom of action. “The loose eye” has, however, become common on common bits.

The noseband. A noseband prevents the cheek of the bit and of the headstall from going forward, and so impedes the true action of the bit. To close the horse’s mouth, in order that a high porte may act against the roof of the mouth, is a monstrous notion. I had the honour to abolish nosebands in the 2nd Life Guards.

Defence against the bit by the tongue. The horse employs his tongue as a defence against the bit, passively as a cushion to protect the more tender parts on which the bit is intended to work, and actively he uses the muscles of the tongue, in resistance to it: this may be proved by using a straight mouthpiece, or one arched upward or downward, but without a porte. From under these a horse will never withdraw his tongue, and he will go with a dead bearing on the hand, though equal, that is, not more on one side of the mouth than on the other. Effect of the porte. Even a very narrow porte, not a quarter the width of the tongue, will suffice, when pressure is used, to defeat this defence, and completely to engage the tongue within the porte. But being then much compressed, it will sustain a great part of the leverage, and the horse will endeavour still more to make his tongue the fulcrum of the bit, and to relieve his bars from that office, by protruding his tongue, and thus forcing the thick part of it within the porte. If the porte is made wide so as to allow space for the tongue, the corners formed by the porte and the cannons (those parts between the porte and the branches) are apt to work injuriously against the bars, and also to slip quite off them, which makes the action of such bits uncertain, though they are very effective and severe if the mouthpiece is no wider than the horse’s mouth. But the mouthpiece which gives complete room for the tongue, and yet brings the cannons into perfect contact with the bars, is that of which M. de Solleysell claims the invention, and which he describes as “à pas d’asne, with the porte gained from the thickness of the heels.” Let the mouthpiece be in width four inches inside, this I believe, will be sufficient for most horses, since the part of a horse’s mouth where the bit should work is narrowest, and the cheeks should consequently be set outward. Let the entrance to the porte, between the heels be three-fourths of an inch, and let the porte open laterally to two and a half inches inside.

Defence by the lip. But when the tongue is perfectly disengaged from the bars by the porte, the horse will still defend them by drawing his lip in on one side, interposing it between one bar and one cannon of the bit, and pulling on one side of his mouth only. It is the common error to attribute this to nature having formed one bar stronger than the other; but these and other tricks are not to be looked on as the results of natural defects, but as habitual defences against the pain caused by a hard, harsh bearing on the horse’s bars; with a smooth and gentle bearing he will not take to them, or will discontinue them. For callous bars Xenophon prescribes gentle friction with oil! and the practice of the Augustan age of the manége, recommended by Berenger was to amputate that part of the tongue which a horse protruded or lolled out!

Defence by the teeth. One of the most common defences against the bit is taking the leg (the lower part of the branch) of the bit with the corner tooth. This is easily counteracted by a lip-strap. It should fasten round the leg of the bit, so as to slide up and down, and should be tight enough to be horizontal.

Bar of the military and driving bit. The reason for the bar at the lower part of a driving bit or a military bit, is to prevent the horse catching his bit over his neighbour’s reins. The French cavalry ordonnance, in discussing the merits of this bar, does not seem to be aware of its origin and meaning.

If the theories here laid down are true, it will result that the common bits are best for the common run of coarse hands, as being less severe, from their action being divided and on less sensible parts; and also, that they should be curbed more loosely, and placed higher in the horse’s mouth, in proportion to the degree of coarseness to be expected in the rider’s hand. Martingale. So although a martingale spoils hands, it may be used as a defence, that is, supposing the necessity of mounting a high, harsh hand on a susceptible horse. In this case an easy snaffle with a running martingale will at least counteract the height of the hand, and the friction will to a certain degree steady and counteract the unequal bearing on the horse’s mouth. A low smooth hand is the only true martingale: this will never be acquired as long as an implement is used which tends to permit harsh, high handling with impunity to the rider.

The snaffle, even of a double bridle, should be sewed to the bridle; it is safer for leading, and it is only the curb bit which you wish to have the power of changing. The reins should be thin and supple, they will last the longer for it; for reins break from being stiff and cracking, and suppleness of reins is essential to delicacy of hand.

As the collected paces of the parade are not in vogue in England, a gentleman rarely has occasion for his curb at all, except to train a horse for a lady, or in the case where a commanding power is required over a horse who, by bad or cruel handling, has become a puller, or habitually restive, or whose animal impetuosity or ferocity leads him to attack his neighbours. In such a case a Chifney bit, with the mouth-piece described, with half the length of leg, and a third part of the weight, will be found more effective than a clipper bit; and at the same time that weight is got rid of, danger is avoided, which, with branches running far below the horse’s mouth, is very great in going through living fences or coverts.

With such a bit, so placed, I have seen the taper tips of the most beautiful fingers in the world constrain the highest-mettled and hottest thorough-bred horses, and “rule them when they’re wildest.” It is an implement which will give to the weakest hand the power of the strongest, which most of the strongest hands cannot be trusted to wield, and which, if ladies’ hands are light, equal, and smooth, will give them the power of riding horses such as few men might venture to mount.
