Probably because the Leicester blood prevails in, or, at least, mingles with, every other long-woolled breed, a great similarity in the appearance and quality of this fleece has become apparent, of late years, in every district of England. The short-woolled fleeces are, to a very considerable degree, unlike in fineness, elasticity, and felting property; the sheep themselves are still more unlike; but the long-wools have, in a great degree, lost their distinctive points--the Lincoln, for example, has not all of his former gaunt carcass, and coarse, entangled wool--the Cotswold has become a variety of the Leicester--in fact, all the long-woolled sheep, both in appearance and fleece, have almost become of one variety; and rarely, except from culpable neglect in the breeder, has the fleece been injuriously weakened, or too much shortened, for the most valuable purposes to which it is devoted. In addition to its length, this wool is characterized by its strength, its transparency, its comparative stoutness, and the slight degree in which it possesses the felting property. Since the extension of the process of combing to wools of a shorter staple, the application of this wool to manufacturing purposes has undergone considerable change. In some respects, the range of its use has been limited; but its demand has, on the whole, increased, and its value is more highly appreciated. Indeed, there are certain important branches of the woollen manufacture, such as worsted stuffs, bombazines, muslin-delaines, etc., in which it can never be superseded; and its rapid extension in the United States, within the past few years, clearly shows that a large and increasing demand for this kind of wool will continue at remunerating prices. This long wool is classed under two divisions, distinguished both by length and the fineness of the fibre. The first--_the long-combing wool_--is used for the manufacture of hard yarn, and the worsted goods for which that thread is adapted, and requires the staple to be long, firm, and little disposed to felt. _The short-combing wool_ has, as its name implies, a shorter staple, and is finer and more felty; the felt is also closer and softer, and is chiefly used for hosiery goods.
