I am not familiar with the work of Edward Thomas. Has he been anthologized much? Though I prefer free verse, or less regular rhyming and rhythm, this poem succeeds better than most because of the nostalgic imagery and the metaphoric connection of the poet with the aspens. And it's just a pleasure to read aloud - with a little practice. One question: is there a typographical error in line 12? should no ceasing be not ceasing or now ceasing? As it is, I haven't figured out how to read it.
