The preserving of a proper balance is the most difficult part of horsemanship, and it must be attended to in every movement that is given to the horse, in accordance with the laws of motion in mechanics. Thus, when the horse is urged forward, the body should lean forwards likewise; and when the horse is checked, the body should be bent backwards. A lady is said to have a good seat when she can see the right shoe of her horse in all his paces, by only bending slightly forwards; and when she has a good seat, particularly if she be courageous and have presence of mind, she will not easily be thrown. It is, however, proper to know what to do in cases of emergency. When a horse rears, the rider should loosen the rein, and press the weight of her body forward; and when a horse kicks, she should hold her body back and keep a tight rein. When a horse will keep turning round several times, he may generally be checked by pulling his head in the opposite direction to that in which he wants to turn; and, when a horse runs away, the best way is not to attempt to pull him in, but for the rider to direct all her energies to keeping her horse in the right course, and retaining her seat. When a horse shies it is from fear, and he should be patted and encouraged; and, when a horse stumbles, his rider should raise and support him by pulling in his head, and at the same time throwing her body back. I do not know whether you have a _pony-carriage_; but, if you have not, I would advise you to get one, as you would find it very useful in summer to drive round your park, and to pay visits to your neighbours. In a close carriage you see very little of the scenery, and enjoy but little benefit from the air; whereas, in an open carriage, you have more enjoyment of the beauty of the country than even in walking; and you have every advantage from the air without running so much risk of taking cold, as you would do if you were to open the windows of a close carriage. _Àpropos_ to this, I have often wondered that no better means have yet been contrived of ventilating a close carriage than opening the windows, the draught from which is sure to give cold to some one. Surely a ventilator might be fixed in the roof, and a little shutter contrived to slide below it, when it was not wanted, which might be moved by a string inside the carriage. I have lately seen, in the _coupé_ of a French diligence in the South of France, a little opening just above the windows, which was filled in with double _toile métallique_, or wire cloth, so very fine as to admit but little light, and no perceptible air, and which was yet sufficient to prevent the glass from becoming covered with steam when all the windows were closed; and something of the kind might, I think, be generally adopted.
