Kelly Burn, the boundary here between Ayrshire and Renfrewshire, rises four miles to the east, and ripples down its glen to the sea at Wemyss Bay. It has dry braes, covered with bent, grass, and thyme, and damp hollows, with sprotts and rue, recalling the curious old ballad, renovated by Burns, and beginning---

"There lived a carle on Kellyburn braes (Hey, and the rue grows bonnie wi' thyme),

And he had a wife was the plague o' his days ; And the thyme it is withered, and rue is in prime."
