The Sardinian saddle has a bare wooden tree very similar to the Hungarian. A common blanket, folded in twelve thicknesses, is placed under it. The girth and surcingle are of leather. Without expressing any opinion as to the comparative merits of these different saddles, I may be permitted to give a few general principles, which I regard as infallible in the choice of a saddle. The side-boards should be large, and made to conform to the shape of the horse's back, thereby distributing the burden over a large surface. It should stand up well above the spine, so as to admit a free circulation of air under it. For long journeys, the crupper, where it comes in contact with the tail, should be made of soft leather. It should be drawn back only far enough to hold the saddle from the withers. Some horses require much more tension upon the crupper than others. The girth should be made broad, of a soft and elastic material. Those made of hair, in use among the Mexicans, fulfill the precited conditions. A light and easy bit, which will not fret or chafe the horse, is recommended. The saddle-blanket must be folded even and smooth, and placed on so as to cover every part of the back that comes in contact with the saddle, and in warm weather it is well to place a gunny bag under the blanket, as it is cooler than the wool. It will have been observed that, in the French service, the folded saddle-blanket is tied to the pommel to prevent it slipping back. This is well if the blanket be taken off and thoroughly dried whenever the horse is unsaddled. A saddle-blanket made of moss is used in some of the Southwestern States, which is regarded by many as the perfection of this article of horse equipment. It is a mat woven into the proper shape and size from the beaten fibres of moss that hangs from the trees in our Southern States. It is cheap, durable, is not in any way affected by sweat, and does not chafe or heat the horse's spine like the woolen blanket. Its open texture allows a rapid evaporation, which tends to keep the back cool, and obviates the danger of stripping and sudden exposure of the heated parts to the sun and air. The experience of some of our officers who have used this mat for years in Mexico and Texas corroborates all I have said in its favor; and they are unanimous in the opinion that a horse will never get a sore back when it is placed under a good saddle. A saddle made by the Mexicans in California is called the _California saddle_. This is extensively used upon the Pacific slope of the mountains, and is believed to possess, at least, as many advantages for rough frontier service as any other pattern that has been invented. Those hardy and experienced veterans, the mountaineers, could not be persuaded to ride any other saddle, and their ripened knowledge of such matters certainly gives weight to their conclusions.
