As to the long horns, which came originally from Craven in Yorkshire, it may be remarked that this breed has been rapidly disappearing of late, and has everywhere given place to better kinds. Of this species there are--or perhaps were--two leading classes, the Lancashire and the Leicestershire improved. Of the short horns, the leading breeds are the Dutch, the Holderness, the Teeswater, the Yorkshire, the Durham, the Northumberland, and some others. AMERICAN CATTLE. The breeds of cattle which stock the farms of the United States are all derived from Europe, and, with few exceptions, from Great Britain. The highest breeds at the present time are of comparatively recent origin, since the great improvements in breeding were only commenced at about the period of the American Revolution. The old importations made by the early settlers, must consequently have been from comparatively inferior grades. In some sections of the Union, and more particularly in New England, the primitive stock is thought to have undergone considerable improvement; whilst in many parts of the Middle, and especially of the Southern States, a greater or less depreciation has ensued. The prevailing stock in the Eastern States is believed to be derived from the North Devons, most of the excellent marks and qualities of which they possess. For this reason they are very highly esteemed, and have been frequently called the American Devon. The most valuable working oxen are chiefly of this breed, which also contributes so largely to the best displays of beef found in the markets of Boston, New York, and Philadelphia. By means of this domestic stock, and the importations still extensively made of selections from the short horns, and others of the finest European breeds, the cattle, not only of New England, but of other sections, are rapidly improving, especially in the Middle and Western States. A brief sketch of the principal breeds of American cattle, as well as of the grades or common stock of the country, will be of service to the farmer in making an intelligent selection with reference to the special object of pursuit--whether it be the dairy, the production of beef, or the raising of cattle for work.
