AMHERST, a district and city within the Tenasserim division of British Bunnell, and within the jurisdiction of the chief commissioner of that province. The DISTRICT forms a narrow strip of land between the Indian Ocean and the mountains which separate it from the independent kingdom of Siam. It lies in 160 N. lat., 98° E. long., and consists partly of fertile valleys formed by spurs of the mountain system which divides it from Siam, and partly of a rich alluvial tract created by the great rivers which issue from them. The most important of these are the Salween river and the Houng-da-raw Khyoung. The river highways bring down inexhaustible supplies of rice to Maulmain, the chief town of the district, as also of the province of Tenasserim, and the second city in British Burmah. The district comprises an area of 15,144 square miles, of which 346 are cultivated, 4889 are capable of being brought under cultivation, and the remaining 9909 square miles are returned as uncultivable. The population in 1872 numbered 235,738 souls, occupying 38,945 houses, and consisting of 203,774 Buddhists, 15,598 Hindus, 12,279 Mahometans, and 4081 Christians.
