Some of you may perhaps have seen the very kind things which so many of the papers said about "The Wallypug of Why." Now I am going to tell you a secret, even at the risk of seeming ungrateful to them.It is this. Much as I value their kind opinion, and proud and happy as I am that my book has met with their approval, I value your criticism even more highly than theirs, and I am going to ask you to do me a great favour. I have had so many letters from little friends about "The Wallypug of Why" that it has made me greedy, and, like Oliver, I want more. So will you please write me a letter too,...
