Edinburgh, Dec. 31. 1850.
_Darby and Joan._--Can any of your readers refer me to a copy of the ballad
of Darby and Joan? There is a tradition in the parish of Helaugh, near
Tadcaster, that they were inhabitants of that village, and that the ballad
is the composition of some poet who was a constant visitor to the Duke of
Wharton, when living in the manor house.
