Watercolour by Thomas (Prinsep, 1800-1830) of moored boats from Arakan or Chittagong, dated c.1828. The image is inscribed on the album page: 'Mugh boats'. Mugh is the name commonly applied to natives of Arakan or Chittagong. Thomas Prinsep came from a family who served in India for three generations; five of his brothers were also in the country. Thomas was in charge of the surveying of the Sunderbunds; a large area of fresh and saltwater mangrove swamp in Bengal covering sixty to eighty miles and consisting of flat marshy islands covered with dense forests, inhabited by crocodiles and forming the final retreat of the Bengal Tiger. He made a detailed survey of the area and his maps of the 24 Parganas District formed part of the Hodges map of the Sunderbunds published in 1831. The limits of the Sunderbunds forest is known as 'The Princeps Line'. Thomas was sent to Chittagong in 1826.
