​KAN-SUH, a north-western province of China, bounded N. by Mongolia, E. by Shen-si, S. by Szech’uen, W. by Tibet and N.W. by Turkestan. The boundary on the N. remains undefined, but the province may be said to occupy the territory lying between 32° 30′ and 40° N., and 108° and 98° 20′ E., and to contain about 260,000 sq. m. The population is estimated at 9,800,000. Western Kan-suh is mountainous, and largely a wilderness of sand and snow, but east of the Hwang-ho the country is cultivated. The principal river is the Hwang-ho, and in the mountains to the south of Lan-chow Fu rises the Wei-ho, which traverses Shen-si and flows into the Hwang-ho at Tung-kwan. The chief products of Kan-suh are cloth, horse hides, a kind of curd like butter which is known by the Mongols under the name of wuta, musk, plums, onions, dates, sweet melons and medicines.
