C. H. T. Crosthwaite, The Pacification of Burma
“ The passes through this range lead to a hilly plateau, the altitude of which is from two to four thousand feet above sea-level rising occasionally to five and six thousand feet. This plateau is intersected from north to south by the Salween River, which, rising somewhere in the mountains to the north-west of Yunnan, enters the sea at Moulmein. The channel of the Salween is in most places deep. To the east the high land continues, but is rougher and more mountainous, and rises until the watershed between the Salween and the Mekong is crossed. ”
