Uncle Jaque, I found a version in Randolph, as sung by Mrs. Marie Wilbur of Arkansas. The title here is "How Tedious and Tasteless the Hours." Since this thread is long and non-specific, I will post it under that title in a new thread.
"Greenfields" has been used for a completely different modern tune and song in the DT and Forum, although Sandburg used it (he reproduced text and music from the Missouri Harmony, 1808, page 152-155). The author is unknown, although Newton has been named in some later hymn books.
