TWEEDALE, or PEEBLES, a county of Scotland, taking the name of Tweedale from the river Tweed, that runs through the whole length of the county, stretches about 25 miles in length, and at some places 18 in breadth; bounded on the east by Ettrick Forest, on the south by Annandale, on the west by Clydesdale, and on the north by Mid-Lothian. Tweedale is a hilly country, well watered with the Tweed, the Yarrow, and a great number of smaller streams, that fertilize the valleys, which produce good harvests of oats and barley, with some proportion of wheat. All the rivers of any consequence abound with trout and salmon. The lake called West-Water-Loch, swims with a prodigious number of eels. In the month of August, when the west wind blows, they tumble into the river Yarrow in such shoals, that the people who wade in to catch them run the risk of being overturned. There is another lake on the borders of Annandale, called Lochgenneen, which forms a cataract over a precipice 250 paces high: here the water falls with such a momentum as to kill the fish underneath. About the middle of this county is the hill or mountain of Braidalbh; from the top of which the sea may be seen on each side of the island. Tweedale abounds with limestone and freestone. The hills are generally as green as the downs in Sussex, and feed innumerable flocks of sheep, that yield great quantities of excellent wool. The country is well shaded with woods and plantations, abounds with all the necessaries of life, and is adorned with many fine seats and populous villages. The earls of March were hereditary sheriffs of Tweedale, which bestows the title of marquis on a branch of the ancient house of Hay, earls of Errol, and hereditary high constables of Scotland. The family of Tweedale is, by the female side, descended from the famous Simon de Fraser, proprietor of great part of this country, who had a great share in obtaining the triple victory at Roslin. In the neighbourhood of Peebles, near the village of Romana, on the river Lene, we see the vestiges of two Roman castella, or stationary forts; and a great many terraces on the neighbouring hills, which perhaps have served as itinerary encampments. In the shire of Tweedale there are many ancient and honourable families of the gentry. Among these Douglas of Cavers, who was hereditary sheriff of the county, still preserves the standard and the iron mace of the gallant lord Douglas, who fell in the battle of Otterburn, just as his troops had defeated and taken Henry Percy, surnamed Hoffpur. In the church-yard of Drumalzier, belonging to an ancient branch of the Hay family, the famous Merlin is supposed to lie buried. There was an old traditional prophecy, that the two kingdoms should be united when the waters of the Tweed and the Panfel should meet at his grave. Accordingly the country people observe, that this meeting happened in consequence of an inundation, at the accession of James VI. to the crown of England.
