Of more frequent use than the wool of the goat is the wool of the camel which grows close to the skin beneath the long hair. In the tropical countries, as in Soudan, the camel has no wool, but in more northern latitudes it yields a crop which increases in quantity and improves in quality as the climate grows colder. Thus in Arabia, Asia Minor, and in most of Persia and Turkestan the yield is small, in the table-lands of Eastern Persia and Afghanistan it is much larger, and on the lofty plateaus of Turkestan and Chinese Tartary as much as ten pounds of wool is obtained yearly from each beast. The clip is taken at the usual moulting season during the spring of the year. The wool of the older camels is coarse and dark, what is taken from the young is finer and lighter, and the most silky and valuable of all is what is obtained from the unborn. The best grade has been more highly esteemed than the wool of any other animal, and rugs in which it constitutes the pile are more valuable than those in which the wool of sheep is used. It is seldom woven in modern rugs, but dyed wool or goats’ hair of similar colour is often substituted for it.

The wool or underhair of the yak is used only among the mountain tribes of Tartary, and is never found in any of the choicer grades of rugs. Occasionally the hair of the horse or cow is employed to a limited extent in the pile of nomadic rugs, where it may be distinguished by its coarse and wiry character. In old rugs of which the pile is much worn cows’ hair will now and then protrude like the hairs of small bristle brushes. Only very rarely is human hair seen in a rug.

Natural colours of the several kinds of wool, which have made it possible to dispense with their dyeing, have always been taken advantage of by weavers. The only black yarn on which the wear of time has left no impress is from the fleece of the proverbially despised black sheep. Shades of white, ivory, brown, grey, rufus, and even a plum are obtained from different varieties. Likewise a wide range of rich chestnut colours are furnished by the camel.

It is but natural that the nomad should depend on the wool of his flocks and herds for warp, weft, and pile; but people of fixed habitations have employed other kinds of material also. Where the sensuous luxury of the East called for magnificent carpets, they were often woven almost entirely of silk, which was easily obtained, as silkworms thrive on the mulberry trees that grow wild on the plains of Central and Southwestern Asia. Silk rugs are still woven in a few cities of Asia Minor and Persia. For the cheaper grades of rugs flax, hemp, and jute have been sparingly used; and during recent years cotton has been widely adopted, particularly in Persian, Indian, and Chinese rugs, on account of its cheapness as compared with wool. It is, however, almost entirely as warp and weft and rarely as pile that it is used. Though much less durable than wool, its white colour is far less likely to darken with age; yet there is a poorer variety which, after being thoroughly wet, acquires a dark colour.

In the preparation of these different textile materials wool requires the greatest care. In some parts of the Orient it is not washed, and the lustrous hues of the pile are attributed to the fact that it is dyed in its naturally greasy state; but in other parts the grease and dirt are carefully removed. This cleansing is a craft that has been transmitted from parent to child, and is practised according to different methods in different parts of the country. One of the chief essentials is an abundance of clear running water free from alkali; for when the water is hard, as is often the case in the more arid parts of the country, it loses some of its cleansing properties, and potash or other chemicals are required to counter-act this unfavourable quality. After the wool has been thoroughly washed it is carefully dried in the sun and open air.

The next important step is the proper sorting, picking, and combing. The sorting consists of the separation of black and light wool, or of an inferior from a better grade; and the picking consists of the removal of burrs or foreign particles. The object of combing is to effect an orderly arrangement of the wool so that it is ready for spinning. One method, corresponding to carding, is to draw the wool repeatedly between rows of upright spikes set in a wooden frame until every matted particle has been separated and all the fibres are disentangled. The older method, still employed in nearly every part of the Orient, consists of “teasing” with the cord of a heavy bow, which is suspended or held firmly by the left hand over the wool, while with the right hand the cord is made to vibrate either by striking it with a wooden instrument or plucking it, so that the fibres of wool are separated and assorted by the vibrations.

When the wool has thus been prepared, it is wound about the distaff and then spun into yarn. In many parts of the Orient the common spinning-wheel has been introduced and adopted for both wool and cotton; in other parts are crudely made spinning-wheels of different design and about the height of a man. The natives of districts more remote from civilisation still cling to the primeval spindle, which sometimes consists of no more than a rounded stick half an inch in diameter and a foot in length with a ball of clay at one end. Many of the nomadic tribes of Asia Minor and Mesopotamia use in place of it a small stone of convenient shape, to which is tied a strip of linen a few inches in length. A few fibres of wool are attached to the end of the linen by twisting them about it, and a few more fibres are similarly attached to these when the stone is suspended and twirled. As the fibres become closely twisted together more fibres are added until on account of the length of the thread thus formed the stone reaches the ground. The thread is then wound about the stone and secured by a couple of loops so as to leave a piece only a few inches in length, to which more wool is attached in continuing the spinning. When a large ball of thread has been spun, it is removed from the stone and the process begun again.
