Most of the adventures in this book really happened. One or two were my own experiences. The others were experiences of boys in my school. Huck Finn really lived. Tom Sawyer is made of three real boys. My book is for boys and girls, but I hope that men and women also will read it. I hope that it will help them remember pleasantly the days when they were boys and girls, and how they felt and thought and talked, what they believed, and what strange things they sometimes did.
