DUMBARTON  , a royal, municipal and

police burgh, seaport, and county town of Dumbartonshire, Scotland, situated on the river Leven, near its confluence with the Clyde, 151 m . W. by N. of Glasgow by the North British and Caledonian railways . Pop . (1891) 17,625; (1901) 19,985 . The Alcluith (" hill of the Clyde ") of the Britons, and Dunbreatan (" fort of the Britons ") of the Celts, it was the capital of the district of Strathclyde . Here, too, the Romans had a naval station which they called Theodosia . Although thus a place of great antiquity, the history of the town practically centres in that of the successive fortresses on the Rock of Dumbarton, a twin-peaked mount, 240 ft. high and a mile in circumference at the base . The fortress was often besieged and sometimes taken, the Picts seizing it in 736 and the Northmen in 87o, but the most effectual surprise of all was that accomplished, in the interests of the young King James VI., by Thomas Crawford of Jordanhill on March 31, 1571 . The castle was held by Queen Mary's adherents, and as it gave them free communication with France, its capture was deemed essential . Crawford decided to climb the highest point, concluding that, owing to its imagined security, it would be carelessly guarded . Favoured with a dark and foggy night the party of 150 men and a guide reached the first ledge of rock undiscovered . In scaling the second precipice one of the men was seized with an epileptic fit on the ladder .

Crawford

bound him to the ladder and then turned it over and was thus enabled to ascend to the summit . At this moment the alarm was given, but the sentinel and the sleepy soldiers were slain and the cannon turned on the garrison . Further resistance being useless, the castle was surrendered . During the governorship of Sir John Menteith, William Wallace was in 1305 imprisoned within its walls before he was removed to London . The higher of the two peaks is known as Wallace's seat, a tower, perhaps the one in which he was incarcerated, being named after him . On the portcullis gateway may still be seen rudely carved heads of Wallace and his betrayer, the latter with his finger in his mouth . Queen Mary, when a child, resided in the castle for a short time . It is an ugly barrack-like structure, defended by a few obsolete guns, although by the Union Treaty it is one of the four fortresses that must be maintained . The rock itself is basalt, with a tendency to columnar formation, and some parts of it have a magnetic quality . The town arms are the elephant and castle, with the motto Fortitudo et fidelitas . Dumbarton was of old the capital of the earldom of Lennox, but was given up by Earl Maldwyn to Alexander II., by whom it was made a royal burgh in 1221 and declared to be free from all imposts and burgh taxes . Later sovereigns gave it other privileges, and the whole were finally confirmed by a charter of James VI .

It had the right to

levy customs and dues on all vessels on the Clyde between Loch Long and the Kelvin . " Offers dues " on foreign ships entering the Clyde were also exacted . In 1700 these rights were transferred to Glasgow by contract, but were afterwards vested in a special trust created by successive acts of parliament . Most of the town lies on the left bank of the Leven, which almost converts the land here into a peninsula, but there is communication with the suburb of Bridgend on the right bank by a five-arched stone bridge, 300 ft. long . The public buildings include the Burgh Hall, the academy (with a graceful steeple), the county buildings, the Denny Memorial, a Literary and a Mechanics' institute, Masonic hall, two cottage hospitals, a fever hospital, a public library and the combination poorhouse . There are two public parks—Broad Meadow (20 acres), part of ground reclaimed in 1859, and Levengrove (32 acres), presented to the corporation in 1885 by Peter Denny and° John McMillan, two ship-builders who helped lay the foundation of the town's present prosperity . The old parish kirkyard was closed in 1856, but a fine cemetery was constructed in its place outside the town . Dumbarton is controlled by a provost and a council . With Port-Glasgow, Renfrew, Rutherglen and Kilmarnock it unites in returning one member to parliament . The principal industry is shipbuilding . The old staple trade of the making of crown glass, begun in 1777, lapsed some 70 years afterwards when the glass duty was abolished . There are several great engineering works, besides iron and brass foundries, saw-mills, rope-yards and sail-making works .

There are quays, docks and a

harbour at the mouth of the Leven, and a pier for river steamers runs out from the Castle rock . The first steam navigation company was established in Dumbarton in 1815, when the " Duke of Welling-ton " (built in the town) plied between Dumbarton and Glasgow . But it was not till . 1844, consequent on the use of iron for vessels, that shipbuilding became the leading industry .
