The Lowlands of Scotland comprehend the south and southeastern portions of the country, and though not the grandest and most romantic, are by far the best cultivated, and in some respects the most beautiful. Including the level ground on the eastern coast to the south of the Moray Firth, they stretch along the coast through portions of Perthshire, and the old kingdom of Fife, towards the regions bounded on either side, by the river and the Firth of Forth, and thence to Kircudbright and the English border, including the principal cities, the most fertile tracts of arable land, the rivers Forth, Clyde and Tweed, and the range of the Cheviot hills, which extend from the north of England towards the north-west, join the Louther hills in the region of Ettrick and Yarrow, with their 'silver streams,' pass through the southern part of Ayrshire and terminate at Loch Ryan, in the Irish Channel. The Clyde is the most important commercial river in Scotland. Taking its origin among the mountains of the south, not far from the early home of its beautiful and more classic sisters, the Tweed and the Annan, it runs in many capricious windings, in a northwesterly direction, leaps in foaming cascades first at Bonnington, and then at Cora Linn, rushes on through the fine country of Lanarkshire, till, joined by many tributary streams, it passes through the large and flourishing city of Glasgow, bearing upon its bosom the vast commerce and population of the neighboring regions, flows around the walls of old Dumbarton Castle, with its time-worn battlements and glorious memories, in sight, too, of the lofty Ben Lomond, and the beautiful lake which it protects, touches the ancient city of Greenock, expands into the Firth of Clyde, and gradually loses itself amid the picturesque islands which adorn the western coast of Scotland. Were it possible, by placing ourselves upon some lofty elevation, to take in at one glance, the whole of this varied landscape of lake, river, and mountain; of tarn, trosach and moor, with verdant vales, and woody slopes between, we should confess that it was one of as rare beauty and wild magnificence as ever greeted the vision of man. And were our minds steeped in ancient and poetic lore, we should be prepared to appreciate the faithfulness and splendor of Burns's allegorical description of the "Genius of Scotland." "Green, slender, leaf-clad holly boughs, Were twisted gracefu' round her brows, I took her for some Scottish Muse, By that same token, And come to stop those reckless vows Would soon be broken. A hair-brained sentimental trace, Was strongly marked in her face; A wildly witty-rustic grace, Shone full upon her, Her eye e'en turned on empty space, Beamed keen with honor.
