GRANGEMOUTH, police burgh, seaport and parish, Stirl ingshire, Scotland. Pop. (1931) I1,798. It is situated on the south shore of the estuary of the Forth, at the mouth of the Carron and also of Grange Burn, a right-hand tributary of the Carron, 3 m. N.E. of Falkirk by the L.M.S.R. and L.N.E.R. It is the terminus of the Forth and Clyde Canal, from the opening of which (1789) its history may be dated, and is now the chief port of the Firth W. of Leith. With Stirling and Falkirk, Grangemouth returns one member to parliament. The growth of the docks, which cover an area of 58 acres, rendered it necessary to divert the influx of the Grange from the Carron to the Forth. Timber, iron and oil are the leading imports, and coal and oil the chief exports. The industries include shipbuilding and rope and sail making. There is regular steamer communication with London, Antwerp, Christiania, Hamburg, Rotterdam, Stockholm, etc. Ex periments in steam navigation were carried out in 1802 with the "Charlotte Dundas" on the Forth and Clyde Canal at Grange mouth.
