INNER MONGOLIA, or _Nui Mungku_, is bounded north by Tsitsihar, the Tsetsen khanate, and Gobi, their frontiers being almost undefinable; east by Kirin and Shingking; south by Chihlí and Shansí; and west by Kansuh. Wherever it runs the Wall is popularly regarded as the boundary between China and Mongolia. The country is divided into six _ming_ or _chalkans_, like our corps, and twenty-four _aimaks_[106] (tribes), which are again placed under forty-nine standards or _khochoun_, each of which generally includes about two thousand families, commanded by hereditary princes, or dsassaks. The principal tribes are the Kortchin and Ortous. The large tribe of the Tsakhars, which occupies the region north of the Wall, is governed by a _tutung_, or general, residing at Kalgan, and their pasture grounds are now nominally included in the province of Chihlí. The province of Shansí in like manner includes the lands occupied by the Toumets, who are under the control of a general stationed at Suiyuen, beyond the Yellow River. In the pastures northwest from Kalgan, in the vicinity of Lakes Chazau and Ichí, and reaching more than a hundred miles from the Great Wall, lie the tracts appropriated to raising horses for the “Yellow Banner Corps.” Excepting such grazing lands or the vast hunting grounds near Jeh-ho, reserved in like manner by the government, small settlements of Chinese are continually squatting over the plains of Inner Mongolia, from whence they have already succeeded in driving many of the aboriginal Mongol tribes off to the north. Those natives who will not retire are fain to save themselves from starvation or absorption by cultivating the soil after the fashion of their neighbors, the Chinese immigrants. It was, indeed, this influx of settlers which led Kanghí to erect the southern portion of Inner Mongolia into prefectures and districts like China Proper. This alteration of habits among its population seems destined, ere long, to modify the aspect of the country. Most of the smaller tribes, except the Ortous, live between the western frontiers of Manchuria, and the steppes reaching north to the Sialkoi range, and south to Chahar. These tribes are peculiarly favored by the Manchus, from their having joined them in their conquest of China, and their leading men are often promoted to high stations in the government of the country. ~OUTER MONGOLIA.~
