“ It formed the tract south of Pegu conquered from Burma in 1826, which was for many years known as the Tenasserim province. The southern extremity of the division approaches the insular region of Malaysia, and it is fringed along its entire western coast by a number of islands, forming in the north the Moscos and in the south the Mergui Archipelago. The eastern frontier is formed by a mountain range 5000 ft. high, which acts as a water-parting between the Tenasserim and the Siamese river systems. ”
