SHEEP IN THE FEEDING YARD
THE WOOL-GROWING INDUSTRY
The rug wools grown in Persia, Turkestan, Turkey in Asia, and the Caucasus Mountains are also characteristic. They vary in fineness, and because they do not readily felt they are the best in the world for rug stock. The "pile" or surface of the rug remains elastic and stands upright even after a hundred years of wear. This quality is due mainly to conditions of climate and soil.
WOOL PRODUCTION
In some instances the wool is obtained by a daily combing of the half-grown lambs. This process, however, is employed in the rug-making districts only; in general, the fleeces are clipped either with shears or machine clippers. In the United States the latter are generally employed, and but little attempt is made either to sort the fleeces or to separate the various qualities of wool in the same fleece.
The raw wool always contains foreign matter such as burs and dirt; it is also saturated with a natural oil which prevents felting. The oil, commonly called "grease," or "yolk," is an important article of commerce; under the name of "lanolin" (adeps lanæ) it is used in medicine and pharmacy as a basis for ointments.
