Her feet beneath her petticoat,
Like little mice, stole in and out,
As if they fear'd the light:
But O, she dances such a way!
No sun upon an Easter-day
Is half so fine a sight.

Compare: "Her pretty feet, like snails, did creep
A little out, and then,
As if they played at bo-peep,
Did soon draw in again"—Herrick, To Mistress Susanna Southwell
