We worked together for seven years. Tenniel and other artists declared I would not work with Carroll for seven weeks! I accepted the challenge, but I, for that purpose, adopted quite a new method. No artist is more matter-of-fact or businesslike than myself: to Carroll I was not Hy. F., but someone else, as he was someone else. I was wilful and erratic, bordering on insanity. We therefore got on splendidly.
