John Crawfurd was an envoy to Cochin China and Siam in 1821 before he succeeded William Farquhar as Singapore's second Resident in 1823. Crawfurd's diplomatic voyage went through modern day Thailand, Vietnam and the Malay Peninsula. His account of Singapore is accompanied by a view of the town and roads, and a plan of Singapore town. It is significant for its early 1820s description of Singapore's natural habitat, its early years of trade, and descriptions of his own contributions to Singapore's early years as a trading settlement.
