It would not be possible to give in detail the various breeds of sheep existing in different countries. Merino sheep are now bred in many parts of the world, and, together with the high crossbreds, are the source of all the fine wools known as merino, half-blood, and three-eighths wools. Long wools are derived from various native breeds, chiefly English, and from the lower crossbreds of merinos, such as quarter and low quarter bloods. Chinese, Siberian, and Turkish wools, as well as many other uncivilized types, are usually very long and coarse, and are known as carpet and braid wools. [Sidenote: _Sources_] Most of the best merino wools come from Australia, the next best from South Africa, and from South America. The latter have one fault in that they contain many spiral burrs which are difficult to remove, and which frequently get through the machines and show up as imperfections in the cloth. Europe grows some very fine short wools, but these hardly ever leave the countries they are grown in. [Sidenote: _U. S. Domestic_] United States wools are known as “domestic” and “territory.” Domestic wools are those grown in the eastern and middle western states, notably in the Ohio valley. These contain the highest grades of merino wools grown in this country. It must be remembered that sheep raising began in the East, and as civilization expanded, was gradually crowded further and further westward. The opening of the Erie Canal in 1825 made available the fertile pasture lands of the Ohio valley. The Ohio Canal eight years later opened up still more territory, and in 1849 during the famous gold rush, sheep were first taken to California. [Sidenote: _Territory_] The territory wools are those grown in the Rocky Mountain Plateau states. Recently, with improved methods and greater care in breeding, some very fine wools have been derived from Idaho, Wyoming, Nevada, and Montana, and from a few other states. The Texas and California wools are usually classed separately, because they are in most cases clipped twice a year. A little later we shall discuss the various grades and sorts of wool obtained from the different breeds, but as the wool is shorn or pulled before it is graded, we shall take up these processes first.
