To W.H. Auden (excerpt #2)

All I remember about the start of The Hobbit is sitting correcting School Certificate papers in the everlasting weariness of that annual task forced on impecunious academics with children. On a blank leaf I scrawled: 'In a hole in the ground there lived a hobbit'. I did not and do not know why. I did nothing about it, for a long time, and for some years I got no further than the production of Thror's Map. But it became The Hobbit in the early 1930s, and was eventually published not because of my own children's enthusiasm (though they liked it well enough), but because I lent it to the then Rev. Mother of Cherwell Edge when she had flu, and it was seen by a former student who was at that time in the office of Allen and Unwin. It was I believe tried out on Rayner Unwin; but for whom when grown up I think I should never have got the Trilogy published.
