CARTSDYKE, for a time a quoad sacra parish, in the EAST parish of GREENOCK, burgh of GREENOCK, Lower ward of the county of RENFREW; containing 3651 inhabitants. This place is situated on the Firth of Clyde, and adjoins the town of Greenock, of which it has become a suburb, on the east side. It is also called Crawfurdsdyke, from the erection of a small quay by its proprietor, Thomas Crawford, Esq., who obtained from Charles I. a charter erecting his lands here into a burgh of barony. There is a good roadstead, in which ships ride at anchor, and the place has two or three small quays: it was of considerable importance for shipping, before the town of Greenock existed. A mechanics' library here contains nearly 1500 volumes. The parish was separated from Greenock in 1839, for ecclesiastical purposes, and was in the presbytery of Greenock and synod of Glasgow and Ayr. The church, originally in connexion with the Secession Synod, was rebuilt on the same site in 1828, at a cost, including a school-house, of £1052, defrayed by private subscription; it passed from the Established Church to the Free Church, at the time of the Disruption, and contains 906 sittings. Besides the school attached to the church, there are several other schools, affording instruction to a considerable number of children.-See GREENOCK.
