The chief commercial city and port of China, on the Wusung, an affluent of the Yangtse-kiang, 12 m. from the coast, and 160 m. SE. of Nanking; large, densely-peopled suburbs have grown round the closely-packed and walled city, which, with its narrow, unclean streets, presents a slovenly appearance; the French and English occupy the broad-streeted and well-built suburbs in the N.; the low-lying site exposes the city to great heat in the summer, and to frequent epidemics of cholera and fever; an extensive system of canals draws down a great part of the interior produce, and swells the export trade in tea, silk, cotton, rice, sugar, etc.
