If you had the rent of Dee Mills, you would spend it all. Dee Mills, in Cheshire, used to yield a very large annual rent. (Cheshire proverb.)
There was a jolly miller Lived on the river Dee; He worked and sung from morn to night; No lark so blithe as he; And this the burden of his song For ever used to be - I care for nobody, no, not I If nobody cares for me.'
Bickerstaff: Love in a Village (1762).
