A gentle plea to a cow for her milk, offered in exchange for a silk gown. A soft, old-fashioned farmyard rhyme with a lulling repetition to it.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Cushy cow, bonny, let down thy milk,
And I will give thee a gown of silk;
A gown of silk and a silver tee,
If thou wilt let down thy milk to me.
