TCG Letter #255 / Carpenter Letter #109

Tolkien responded to Rayner Unwin's comments about The Fellowship of the Ring. He talks about allegory as well as other literary illusions.

Tolkien mentions in a post script that he is revising The Hobbit, which had needed to be amended due to work on The Lord of the Rings.^{For details on these revisions see Hammond/Scull, Reader's Guide, Part 1, p. 509 onwards.[1]}
