The poem
"Why can't you say what you mean straight out in prose?" Well, say it yourself: then say "It's that, but more, Or less perhaps, or not that way, or not That after all." The meaning of a song Might be an undernote; this tree might mean That leaf as much as trunk, branch, other leaves. And does one know till one begins? And let's Look over hedges far as eyesight lets us, Since road's not, surely, road, but road and hedge And feet and sky and smell of hawthorn, horse-dung.
