The unusual name derives from its use to hide stolen cattle by the
Border Reivers of the Johnstone clan who were referred to by their enemies as "devils"; it is also called ''Marquis of Annandale's Beef-Tub
(or Beef-Stand'') after the
Lord of Annandale, chief of the raiding "loons" (here meaning "lads", rather than "
lunatics"); the name may also refer to the resemblance the valley bears to a tub used for preserving meat. The Scots Dialect Dictionary, first published 1911 by Chambers and compiled by the lexicographer Alexander Warrack, gives the following; “deil’s beef-tub n. a roaring linn”. In the eighteenth and nineteenth century the local town of Moffat was famed for its sulphur baths. The
sulphurous water emanated out of the ground at the Moffat Well adjacent to the Devil’s Beef Tub. This was then transported to the town bath house where its efficacious properties were enjoyed by the public. It would appear that beef-tub is a corruption of bathtub. ==History==
