Note {6} — Chapter LIX
Henry Yule translation
Note 6.—The towns and villages were probably those immediately north of the Great Wall, between 112° and 115° East longitude, of which many remains exist, ascribed to the time of the Yuen or Mongol Dynasty. This tract, between the Great Wall and the volcanic plateau of Mongolia, is extensively colonised by Chinese, and has resumed the flourishing aspect that Polo describes. It is known now as the Ku-wei, or extramural region.
