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.

A very important addition to the harbour accommodations of Port Glasgow was obtained a few years back in the erection of wet-docks. The then existing harbours having been found much too small for the increasing number of ships belonging to the port, the inhabitants of the town resolved to avail themselves of their local advantages, by converting the Bay of Newark, naturally adapted to the purpose, into a spacious dock, where vessels of the largest class might lie securely afloat in every state of the tide. The trustees of the harbours obtained an act of parliament, investing them with the necessary powers for carrying this desirable object into effect; and funds having been secured, they were enabled to commence the work, which was soon in rapid progress, and completed about twelve years ago. This dock, having spacious quays, with a twenty-five feet depth of water alongside, holds out special advantages to the trade, both in point of safety and convenience.

The charges levied at this port are on the most moderate scale, and considerably below the rates imposed at the neighbouring ports. To merchants engaged in trade with the Clyde, Port Glasgow thus presents the double advantage of low charges and very superior accommodation; while, at the same time, the privileges of the warehousing system are on a footing equal to those of any other port in the kingdom. Warehouse-room is provided on a very extensive scale, and is open for the general accommodation of the trade, on very moderate terms. In addition to the regular bonded warehouses, there is a large area for receiving wood into bond, and an excellent warehouse for crushing refined sugars, in which large quantities of that article are prepared for exportation to the Mediterranean markets.

Shipbuilding is also carried on at this port to a considerable extent: of late years the builders have been chiefly employed in the construction of steamboats, of which they have produced a great number, some of them of the largest class, and all of very superior workmanship. From the nature of the trade, the rope-work and canvas factory are here in a state of constant activity, and give employment to a great number of hands. The vast improvements effected within the last few years, by deepening the river, and extending the harbours and docks as already mentioned, give Port Glasgow just cause to anticipate all the advantages arising from a prosperous and extending commerce.
