"Confessions of a Caricaturist", vol. 1 (1901)
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.
To have known the man was even as great a treat as to read his books. Lewis Carroll was as unlike any other man as his books were unlike any other author's books. It was a relief to meet the pure simple, innocent dreamer of children, after the selfish commercial mind of most authors.
In More Romps there is plenty of healthy spirit, but just a suspicion of vulgarity, against which Mr. Harry Furniss would do well to guard in his future illustration of childish revelry.

The artist's tact in meeting the author in the wood where things have no names kept their association alive for the seven years that Carroll was puttering with the book [Sylvie and Bruno] and that Furniss was supposed to be looking at the pictures.
