The productions of Koko-nor consist of grain and other vegetables raised along the bottoms of the rivers and margins of the lakes; sheep, cattle, horses, camels, and other animals. Alpine hares, wild asses,[111] wild yaks, vultures, lammergeiers, pheasants, antelopes, wolves, mountain sheep, and wild camels are among the denizens of the wilds. The Chinese have settled among the tribes, and Mohammedans of Turkish origin are found in the large towns. There are eight corps between Koko-nor and Uliasutai, comprising all the tribes and banners, and over which are placed as many supreme generals or commanders appointed from Peking. The leading tribes in Koko-nor are Eleuths, Tanguts, and Tourbeths, the former of whom are the remnants of one of the most powerful tribes in Central Asia. Tangout submitted to the Emperor in 1690, and its population since the incorporation has greatly increased. They inhabit the hilly region of Kansuh, Koko-nor, Eastern Tsaidam, and the basin of the Upper Yellow River. They resemble gipsies, being above the average in height, with thick-set features, broad shoulders, hair and whiskers, black, dark eyes, nose straight, lips thick and protruding, face long and never flat, skin tawny. Unlike the Mongols and Chinese they have a strong growth of beard and whiskers which, however, they always shave. They wear no tail, but shave their heads; their dress consists of furs and cloths made into long coats that reach to the knees. Shirts or trowsers are not made use of; their upper legs are generally left bare. Women dress like the men. Their habitations are wooden huts or black cloth tents. The Tangut is cunning, stingy, lazy, and shiftless. His sole occupation that of tending cattle (yaks). He is even more zealous a Buddhist than are the Mongols, and extremely superstitious.[112] The trade at Síning is large, but not equal to that between Yunnan and Burmah at Talí and Bhamo; dates, rhubarb, chowries, precious stones, felts, cloths, etc., are among the commodities seen in the bazaar. It lies about a hundred miles from the sea, at an elevation of 7,800 feet, and near it is the famous lamasary of Kumbum, where MM. Huc and Gabet lived in 1845. The town is well situated upon the Síning ho, and though constructed for the most part of wood, presents a fine appearance owing to the number of official buildings therein. The population numbers some 60,000 souls.[113]
