MONG PAI (called Mobye by the Burmese)  , the most

south-westerly of the British Shan States of Burma . It has an approximate area of loon 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 Yon, 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 189o, and died a few years later .
