It might be helpful if you were to quote a MacLeish poem or stanza that illustrates such emulation and that in and of itself is also worth remembering and rereading.
Some 67 years ago I spent a few months focusing on MacLeish -- I doubt there's much there worth rereading. I own the Collected Poems (of that date), but I haven't opened the book (or been tempted to open it) in all those years. He tried hard -- but he's a yawn.
(He did help get Pound out of St. Elizabeth's.)
