and hovels afford shelter for both rich and poor.[108] The four khanates constitute one _aimak_ or tribe, subdivided into eighty-six standards, each of which is restricted to a certain territory, within which it wanders about at pleasure. There are altogether one hundred and thirty-five standards of the Mongols. The Kalkas chiefly live between the Altai Mountains and Gobi, but do not cultivate the soil to much effect. They are devoted to Buddhism, and the lamas hold most of the power in their hands through the _Kutuktu_. They render an annual tribute to the Emperor of horses, camels, sheep, and other animals or their skins, and receive presents in return of many times its value, so that they are kept in subjection by constant bribing; the least restiveness on their part is visited by a reduction of presents and other penalties. An energetic government, however, is not wanting in addition. The supreme tribunal is at Urga; it is the _yamun_, par excellence, and has both civil and military jurisdiction. The decisions are subject to the revision of the two Chinese residents, and sentences are usually carried into execution after their confirmation. The punishments are horribly severe; but only a decided and cruel hand over these wild tribes can keep them from constant strife. Letters are encouraged among them by the Manchus, but with little success. Many Buddhist books have been translated into Mongolian by order of the Emperors; nor can we wonder at the indifference to literature when this stuff is the aliment provided them. Their tents, or _yurts_, are made of wooden laths fastened together so as to form a coarse lattice-work; the framework consists of several lengths secured with ropes, leaving a door about three feet square. The average size is twelve feet across and ten feet high; its shape is round and the conical roof admits light where it emits smoke. The poles or rafters are looped to the sides, and fastened to a hoop at the top. Upon this framework sheets of heavy felt are secured according to the season. A hearth in the centre holds the fire which heats the kettle hanging over it, and warms the inmates squatted round, who usually place only felt and sheepskins under them. The felt protects from cold, rain, snow, and heat in a wonderful manner. A first-class _yurt_ is by no means an uncomfortable dwelling, with its furniture, lining, shrine, and hot kettle in the centre. A carpet for sleeping and sitting on is sometimes seen in _yurts_ of the wealthier classes; in these, too, the walls are lined with cotton or silk, and the floors are of wood. The lodges of the rich Kalkas have several apartments, and are elegantly furnished, but destitute of cleanliness, comfort, or airiness. Most of their cloths, utensils, and arms are procured from the Chinese. The Sunnites are fewer than the Kalkas, and roam the wide wastes of Gobi. Both derive some revenue from conducting caravans across their country,
