Richard,
I did some research on Stuart Gerry Brown, one of the authors of the "Reading Poems" book Mr. Bones seems to have had when he died. I found this collection on Syracuse University's Website:
Stuart Gerry Brown Papers An inventory of his papers at Syracuse University
It's a description for a collection of his papers, and it includes a brief Biography of the man.
Born April 13, 1912, in Buffalo, New York, to Charles H., Jr. and Edith (Brown) Brown, he received his A.B. degree from Amherst College in 1934 and his Ph.D. from Princeton University in 1937. In 1937 he became an English instructor at the University of Wisconsin. In 1940, he went to Grinnell College as an associate professor of English and was a full professor of English when he left Grinnell in 1947 to become a professor of Citizenship and American Culture at the Maxwell Graduate School of Citizenship and Public Affairs at Syracuse University. During 1961-1962 and 1964-1965, he was visiting professor at the East-West Cultural Center at the University of Hawaii. In August of 1965, Mr. Brown resigned from Syracuse University to become graduate professor of American Studies at the East-West Center.
IDK about you, but this sounds like the Stuart Gerry Brown we're looking for. Get this though. The collection includes letters and papers he received from students. If this guy taught Mr. Bones, he might have an assignment or letter from him here in this collection.
It looks like we need to reach out to the University in advance to schedule an appointment to review the papers. I'm not sure if you or anybody else has followed this lead yet, but if not, I suppose anybody whose able to make the trip ought to go and see if there's a clue in these papers.
