"about ten days ago I got started on a new book, and am completely, brazenly devoted to it: my hair is uncut, my letters are unwritten, the house is a shambles, and I sit here as happy as Mrs. Jellaby, though I am in 1836, not Africa. It won't go on like this, I shall fall over some obstacle, and wake out of my dreams with a black eye and broken shins: but while it does last, I daren't interrupt it. I haven't had such a spell of writing for nearly three years."
