The ground on which this town has been erected belonged originally to the estate of Newark, and was purchased by the magistrates of Glasgow, in 1668, in order to provide a convenient harbour for the merchant-vessels belonging to that city--hence the name of Port Glasgow. In 1775, a charter was obtained from parliament, conferring on the town the privilege of a burgh of barony, and granting a constitution, which vested the management of its municipal affairs in a council of thirteen, including two baillies. By the Burgh-Reform Act, the number was reduced to nine, consisting of a provost, two baillies, and six councillors. The Reform Bill elevated it to the rank of a parliamentary burgh; and, in connexion with Kilmarnock, Rutherglen, Dumbarton, and Renfrew, it sends one member to parliament. In its general appearance, Port Glasgow presents an air of much neatness and regularity. The streets are straight, and for the most part cross each other at right angles; while the houses, nearly uniform in size, and generally whitewashed, give to the whole a light and regular appearance. Among the modern buildings the town-house, and parish-church are chiefly deserving of notice. The town-hall, of plain but substantial workmanship, is ornamented in front with a portico, resting on four massy fluted pillars, and surmounted with a handsome spire, which rises from the centre. Of this edifice, the ground-floor has been laid out chiefly in shops; but the upper story, in addition to the chambers of the council and town-clerk, contains a large and commodious reading-room, with several apartments occupied as mercantile counting-rooms. The church was finished seventeen years ago, and affords accommodation for about twelve hundred persons. It is square in form, and plain in its exterior; but is much and deservedly admired for the simplicity and elegance of its internal arrangement. The wealthy inhabitants of the place did themselves great honor, and at the same time set a valuable example to others, by gratuitously contributing a sum of fifteen hundred pounds to assist in the expenses of its erection. Attached to this Port are two capacious harbours, substantially built, and so completely sheltered from storms, that the vessels moored within them have rarely been found to suffer injury even in the severest weather. These harbours are furnished with ample quay and shed-room, and also with a commodious graving-dock--the oldest in Scotland. The largest vessels that trade to the Clyde are found at this port; such is the facility of access to this harbour, that vessels which draw twenty-one feet of water are towed up and down the channel with the greatest ease and safety.
