In the manufacture of some sorts of _cords_ from the intestines of sheep, the outer peritoneal coat is taken off and manufactured into a thread to sew intestines, and make the cords of rackets and battledores. Future washings cleanse the guts, which are then twisted into different-sized cords for various purposes; some of the best known of which are whip-cords, hatter's cords for bow-strings, clock-maker's cords, bands for spinning-wheels, now almost obsolete, and fiddle and harp-strings. Of the last class, the cords manufactured in Italy are superior in goodness and strength; and the reason assigned is, that the sheep of that country are both smaller and leaner than the breeds most in vogue in England and in this country. The difficulty in manufacturing from other breeds of sheep lies, it seems, in making the treble strings from the fine peritoneal coat, their chief fault being weakness; by reason of which the smaller ones are hardly able to bear the stretch required for the higher notes in concert-pitch, maintaining, at the same time, in their form and construction, that tenuity or smallness of diameter which is required in order to produce a brilliant and clear tone. [Illustration] DISEASES AND THEIR REMEDIES. The dry and healthful climate, the rolling surface, and the sweet and varied herbage, which generally prevail in the United States, insure perfect health to an originally sound and well-selected flock, unless they are peculiarly exposed to disease. No country is better suited to sheep than most of the Northern and some of the Southern portions of our own. In Europe, and especially in England, where the system of management is, necessarily, in the highest degree artificial, consisting, frequently, in an early and continued forcing of the system, folding on wet, ploughed ground, and the excessive use of that watery food, the Swedish turnip, there are numerous and fatal diseases, a long list of which invariably cumbers the pages of foreign writers on this animal. The diseases incident to our flocks, on the contrary, may generally be considered as casualties, rather than as inbred, or necessarily arising from the quality of food, or from local causes. It may be safely asserted that, with a dry pasture, well stocked with varied and nutritious grasses; a clear, running stream; sufficient shade and protection against severe storms; a constant supply of salt, tar, and sulphur in summer; good hay, and sometimes roots, with ample shelters in winter--young sheep, originally sound and healthy, will seldom or never become diseased on American soil.
