Horses should always be _cleaned_ in the open air, if the weather will permit; as they frequently hurt themselves against their stalls when cleaned in the stable, and sometimes acquire a habit of crib-biting. Many horses have skins so fine as to be unable to bear the use of the common curry-comb, and these horses should be cleaned with brushes the bristles of which are of uneven length. Good cleaning is a most essential point in the management of a horse; and the horse ought to be so clean as not to soil your hand, or your pocket-handkerchief, if drawn over his back. Another point to be attended to, after a horse has had unusual work, is, to let the groom rub his legs down well, particularly his back sinews: each leg should be rubbed for at least ten minutes. When horses come in warm, with their legs very dirty, they should not be washed immediately, but they should be rubbed dry with straw, and only some of the dirt taken off with a dry brush. The feet should, however, be examined, and any stones that may be in should be picked out, and the soles of the feet washed. A horse, when very hot, should also not be covered with a cloth, till he has been rubbed dry with straw. Washing the legs of a horse with cold water, when the horse comes in hot and dirty, is sure to give a sudden chill; and putting on a cloth, while the hair of a horse is wet from the effects of violent exercise, sends the perspiration in, and is sure to lay the foundation for disease. When a horse is very hot, he should be rubbed for half an hour before any cloth is put on at all; and then, if the heat of the horse break out into moisture again, the horse should have a second rubbing, after which he should be covered with another quite dry cloth. The coat of a horse generally becomes thick and shaggy in winter, and when it does so the horse may with perfect safety be clipped, and indeed it will be an advantage, as the hair, if short, is much easier dried when wet, and can be more thoroughly cleaned. Great care, however, must be taken to protect a horse when newly clipped from cold; and, should the weather be severe, the horse not only ought to have an additional cloth on in the stable, but his legs may be bandaged with flannel rollers. The feet of a horse should be stopped every other night with a mixture of clay and cow-dung, and this, and anointing the hoof with tar in hot weather, will keep the horny part of the foot moist and elastic. A great improvement has taken place in shoeing horses within the last few years, by interposing a thick piece of leather, and, in some cases, of India rubber, between the iron shoe and the hoof of the horse.
