Strathmore, the far-stretching band of low country which skirts the frontier mountain-rampart of the Highlands, is flanked along the hither side by the Lennox, the Ochil, and the Sidlaw Hills, and extends from the centre of the main body of Dumbartonshire to the German Ocean at Stonehaven. In this large sense it is exceedingly various in breadth, as well as in the features of its scenery; and comprehends part of Stirlingshire, all Strathallan, most part of Strathearn, and all the Howe of Mearns in Kincardineshire. But the strath is more popularly regarded as consisting only of what is flanked by the Sidlaw Hills, and as extending from Methven in Perthshire to a point a little NE of Brechin in Forfarshire; and, in this view, it is somewhat uniform in breadth and feature, and, belonging principally to Forfarshire, has been succinctly described in our notice of that county. This great district is, in the aggregate, remarkably beautiful and fertile; it contains numerous towns, villages, and elegant mansions; and it is the seat of a great and industrious population. See Glamis Castle and Ruthven.
