Two Burns poems -- "A Poet's Welcome to his love-begotten Daughter; the first instance that entitled him to the venerable appellation of Father," and "To a Mouse, On turning her up in her Nest, with the Plogu, November, 1785."  (This latter required some thought in class about what exactly was going on agriculturally.  Feel free to comment on this [or anything] at amimetobios.com!)  The shifts in Burns's language between Scots light and near-standard English.  The distance therefore between speaker and poet.  Comparison to Wordsworth's writing in the "natural language of natural men."  Then Blake's "To the Evening Star" and a couple of Songs of Innocence and of Experience.  The title of "Songs of Innocence" considered as already impying duality.  The two Chimney Sweep poems.
