MŌNG PAI (called Mobyē by the Burmese), the most south-westerly of the British Shan States of Burma. It has an approximate area of 1000 sq. m., and a population (1901) of 19,351. The general character of the country is hilly, rising westwards in a gentle slope from the chief stream, the Nam Hpilu or Balu. This is navigable for native boats throughout the year to the point where it sinks underground in Karen-ni. The chief cultivation is rice, with about two acres of dry or hill rice to one of wet bottom. The hill fields are left fallow for ten years after two years’ cultivation. The chief, the Sawbwa Hkun Yōn, held charge through the reigns of four Burmese kings, and submitted early in 1887 on the first arrival of British troops. He abdicated in favour of his son in 1890, and died a few years later.
