The emended reading as it appears in the text of this edition is given first, followed by a square bracket and an identification of the source for the change. Corrections made by Mark Twain's typist in the course of transcription are designated “TS”; Albert Bigelow Paine's corrections on the typescripts “TS-ABP”; those which appear in the 1916 edition are designated “Paine I.” Mark Twain's authoritative revisions are designated “TS-MT.” Emendations which appear without ascription are made for the first time in this edition. The rejected manuscript reading follows the source of the emendation. When an emendation supersedes both the manuscript and typescript readings, the rejected readings follow the emendation and are indicated by the appropriate identification. Editorial choices among alternative readings are also included in the list; the words appear in the order the author wrote them, separated by a slash, thus “went/stretched.” An asterisk before the page number refers the reader to the Textual Notes. Page and line references do not include titles and chapter headings.
