a division of Argyleshire in Scotland, which gives the title of marquis to the duke of Argyle. It extends above 30 miles in length from north to south, and about nine at its utmost breadth; bounded on the east by Braidalbin; on the west, by the islands; on the north, by Lochaber; and is divided from Knapdale on the south, by Loch Ettrick, on the banks of which stands the castle of Bergomark, wherein the courts of justice were anciently held. This district, abounding with lakes, is the most pleasant and fertile part of Argyleshire, producing plenty of oats and barley. It once belonged to the ancient family of Mac Dongal, still residing on the spot; but devolved to the lords of Argyle, in consequence of a marriage with the heiress, at that time a branch of the Stuart family. The only place of note in this district is the castle of Dunstaffnage, or St Stephen's mountain, which formerly belonged to the kings of Scotland, some of whom are here interred; at present it is possessed by the duke of Argyle, and governed by an hereditary captain.
