At the River Tweed the border runs down the middle of the river, however between the villages of Wark and Cornhill the Scottish border comes south of the river to enclose a small riverside meadow of approximately 2 to 3 acres (about a hectare). This piece of land is known as the Ba Green. It is said locally that every year the men of Coldstream (to the North of the river) would play mob football with the men of Wark (to the South of the river) at Ba, and the winning side would claim the Ba Green for their country. As Coldstream grew to have a larger population than Wark, the Coldstream men always defeated the Wark men at the game, and so the land became a permanent part of Scotland.
