The towns lying between the Great Wall and Ílí, though politically belonging to Kansuh, are more connected with the colonies in their form of government than with the Eighteen Provinces. The first town beyond the Kiayü Pass is Yuhmun, distant about ninety miles, and is the residence of officers, who attend to the caravans going to and from the pass. It is represented as lying near the junction of two streams, which flow northerly into the Purunkí. The other district town of Tunhwang lies across a mountainous country, upwards of two hundred miles distant. The city of Ngansí chau has been built to facilitate the communication across the desert to Hami or Kamil, the first town in Songaria, and the dépôt of troops, arms, and munitions of war. “With the town of Hami,” says an Austrian visitor in these regions, “the traveller comes upon the southern foot-hills of the Tien shan, and the first traces of Siberian civilization. Magnificent mountain scenery accompanies him on his way toward the west to the Russian line. In the government of Semipolatinsk are the express mail-wagons which stand ready at his order to carry him at furious speed to the town of the same name, then to the right bank of the River Irtysh, and so to Omsk.”[114] This route and that stretching towards the southwest bring an important trade to Hami; the country around it is cultivated by poor Mongols.[115] Barkul, or Chinsí fu, in lat. 43° 40′ N., and long. 93° 30′ E., is the most important place in the department; the district is called Ího hien. A thousand Manchus, and three thousand Chinese, guard the post. The town is situated on the south of Lake Barkul, and its vicinity receives some cultivation. Hami and Turfan each form a _ting_ district in the southeast and west of the department. The trade at all these places consists mostly of articles of food and clothing.
