"Or put in between my leaves a pencil or anything thicker than a single sheet of thin paper. It would strain my back.
"Whenever you have finished reading me, if you are afraid of losing your place, don"t turn down the corner of one of my leaves, but have a neat little Book Mark to put in where you stopped, and then close me and lay me down on my side, so that I can have a good, comfortable rest.
"Remember that I want to visit a great many other little boys after you have done with me. Besides, I may meet you again some day, and you would be sorry to see me looking old and torn and soiled. Help me to keep fresh and clean, and I will help you to be happy."
APPENDIX
_In making a book of this kind, it is impossible to think of all the things that ought to be mentioned. Every reader is certain to know of some game or pastime that has been left out. In order that you may yourself bring this collection nearer completeness, the following Appendix of blank pages has been added. Some reference to everything that is written in the Appendix ought to be made, if only in pencil, in both the body of the book and in the Index._
