On April 26, 1944
the Professor wrote a letter to his youngest son, Christopher.....
"Yesterday felt effects of Sunday night. Went off early to town and did some executors business for Mrs. Wright , gave a poor lecture, saw the Lewises and C.W. (White Horse) for 1/2 hour; mowed three lawns, and wrote letter to John, and struggled with recalcitrant passage in 'The Ring'. At this point I require to know how much later the moon gets up each night when nearing full, and how to stew a rabbit ! "

(Note: "C.W." was Charles Williams. "John" was John Tolkien, the Professor's eldest son. )
