Hab Dab and David Din
Ding the deil oer Dabsons Linn.
Hab Dab means Halbert Dobson; David Din means David Dun; and Dabsons Linn, or Dobs Linn, is a waterfall near the head of Moffat Water.
Dobson and Dun were two Cameronians who lived for security in a cave in the ravine. Here, as they said, they saw the devil in the form of a pack of dried hides, and after fighting the foul fiend for some time, they dinged him into the waterfall.
