Liverpool (585), the third city and first seaport of Great Britain, in Lancashire, on the Mersey, 3 m. from the sea, formerly the chief seat of the slave interest in Britain; owed its present prosperity to the impulse of the cotton trade at the end of the 18th century; progressing rapidly it has now docks stretching six miles along the Mersey, which receive a sixth of the tonnage that visits British ports; through it passes a third of our foreign trade, including enormous imports of wheat and cotton and exports of cotton goods; it possesses shipbuilding and engineering works, iron-foundries, flour, tobacco, and chemical factories; the public buildings, town hall, exchange, colleges, and observatory are fine edifices; it was the native place of W. E. Gladstone.
