"DUMBARTONSHIRE (sic), Co., partly maritime but chiefly inland, in W. of Scotland, comprising a main body and a detached portion; area, 154,542 ac.; pop. 75,333, or 312 persons to each sq.m. The main body is in the shape of a crescent, having the convex side adjacent to the estuary of the Clyde, and measures 1.5 to 14 miles in breadth, and about 38 miles between its extreme points. The N. section (about two-thirds of the entire area), projecting between Loch Long and Loch Lomond, is wholly mountainous, and is celebrated for its picturesque and sublime scenery. Ben Vorlich and Ben Vane, in the extreme N., are 3092 and 3004 ft. high. The lower district along the Clyde is flat, and in general under excellent cultivation. The peninsular par. of Roseneath separates Loch Long and the Gare Loch, offshoots of the Firth of Clyde. The detached section (12 miles by 4 miles) lies 4.5 miles E. of the nearest point of the main body. The rivers, besides the Clyde, are the Leven, Allander, Kelvin, and Endrick. The mfrs. are very important; numerous bleachfields, dye, print, and other works line the banks of the Leven; and there are extensive shipbuilding yards along the Clyde: D. in former times formed part of the territory of Lennox. Vestiges of the Roman wall of Antoninus still exist. The co. comprises 11 pars. and a part, the parl. and royal burgh of Dumbarton (part of the Kilmarnock Burghs), and the police burghs of Cove and Kilcreggan, Helensburgh, and Kirkintilloch. It returns 1 member to Parl."
