In the north-east of their grounds lies the thriving town of Dolon-nor (_i.e._, Seven Lakes), or Lama-miao, of about 20,000 Chinese, founded by Kanghí. The Buddhist temples and manufactories of bells, idols, praying machines, and other religious articles found here, give it its name, and attract the Mongols, whose women array themselves in the jewelry made here. It is in latitude 42° 16′ N., about ten miles from the Shangtu River, a large branch of the river Liao, on a sandy plain, and is approached by a road winding among several lakes. North-west of Dolon-nor are the ruins of the ancient Mongolian capital of Shangtu, rendered more famous among English reading people by Coleridge’s exquisite poem-- In Xanadu did Kubla Khan A stately pleasure-dome decree: Where Alph, the sacred river, ran Through caverns measureless to man Down to a sunless sea. So twice five miles of fertile ground With walls and towers were girdled round-- than by Marco Polo’s relation, which moved the poet to pen the lines. It was planned as Mukden now is, an outer and inner wall inclosing separate peoples, and its tumuli will probably furnish many tablets and relics of the Mongol emperors, when carefully dug over. It was too far from Peking for the Manchu monarchs to rebuild, and the Ming emperors had no power there. It was visited in 1872 by Messrs. Grosvenor and Bushell of the British Legation; Dr. Bushell’s description corroborates Polo’s account and Gerbillon’s later notices of its size.[40] There are several lakes, the largest of which, the Peh hu, in the south-western part, connects with the Pei ho through the river Hü-to. The various branches of the five rivers, whose united waters disembogue at Ta-ku, afford a precarious water communication through the southern half of Chihlí. Their headwaters rise in Shansí and beyond the Great Wall, bringing down much silt, which their lower currents only partially take out into the gulf; this sediment soon destroys the usefulness of the channels by raising them dangerously near the level of the banks. The utilization of their streams is a difficult problem in civil engineering, not only here but throughout the Great Plain.
