"Nevermore," quoth the barred owl.
Thanks, sorry for my misspelling...
I had just assumed it was the fatal bellman from Macbeth.
Or perhaps the bellman from "The Hunting of the Snark." A great poem about orienteering (loosely speaking).
Huh. I had never read the whole thing, and didn't realize how much vocabulary it shares with "Jabberwocky".
