Note: National, provincial and district boundaries have changed considerably since 1908. Typically, old states, ‘divisions’ and districts have been broken into smaller units, and many tahsils upgraded to districts. Some units have since been renamed. Therefore, this article is being posted mainly for its historical value.
River of Burma, called Nam Mao by the Shans, who in ancient days first established themselves in what is now Burma along the Shweh valley. The stream rises in China in the neighbourhood of Tengyiieh, and flows first in a south-westerly and then in a northerly direction past Namhkam village, through the Shan State of Mongmil and along the northern end of the Ruby Mines District into the Irra- waddy, which it reaches at a point 20 miles south of the town of Katha. The total length of the river is about 260 miles. It abounds in rapids, and is but little used for navigation, but is employed freely for floating timber. It has no tributaries of importance.
