Twain's preface tells readers there are autobiographical sources to the events in the novel. It also alerts them to when it is set and notes that the book is intended for children and adults alike. He makes a point to say that the two boys who are at the center of the story are not based on singular individuals.
This brief entry dates the story. Twain wrote the preface in 1876, and his statement that the events are set "thirty or forty" years prior sets the story's time as sometime between 1836 and 1846. It validates the use of so many autobiographical notes in a way that is not common in literature; Twain invites comparison to his own life's events as sources.
