Yule’s map the _Goolan Sigon_ range. The climate is cooler than in Sz’chuen, owing to this elevation, and not very healthy; snow lies for weeks at Yunnan fu, and the summers are charming. The Yangtsz’ enters the province on the northwest for a short distance. The greatest river in it is the Lantsan, which rises in Tibet, and runs for a long distance parallel with and between the Yangtsz’ and Nu Rivers till the three break through the mountains not far from each other, and take different courses,--the largest turning to the eastward across China, the Lantsan southeast through Yunnan to the gulf of Siam, under the name of the Meikon or river of Cambodia, and the third, or Salween, westerly through Burmah. The Meikon receives many large tributaries in its course across the province, and its entire length is not less than 1,500 miles. The Lungchuen, a large affluent of the Irrawadi, runs a little west of the Salween. The Meinam rises in Yunnan, and flows south into Siam under the name of the Nanting, and after a course of nearly eight hundred miles, empties into the sea below Bangkok. East of the Lantsan are several important streams, of which three that unite in Annam to form the Sangkoi, are the largest. The general course of these rivers is southeasterly, and their upper waters are separated by mountain ridges, between which the valleys are often reduced to very narrow limits. There are two lakes in the eastern part of the province, south of the capital, called Sien and Tien; the latter is about seventy miles long by twenty wide, and the Sien hu (_i.e._, ‘Fairy Lake’) about two-thirds as large. Another sheet of water in the northwest, near Talí fu, communicating with the Yangtsz’ kiang, is called Urh hai or Uhr sea, which is more than a hundred miles long, and about twenty in width. ~INHABITANTS AND PRODUCTIONS OF YUNNAN.~
