Preceding two sentences (which allude of course to the Boston Tea Party) are not in Tr. Though it has the physical form of a letterbook and has long been so designated, the “Mercy Warren Letterbook” is not really a letterbook at all. The letter copies in it, extending from 1770 through 1800, are all in unidentified hands (no trace of her hand has been detected in the 94volume); they are arranged by correspondent rather than by date; editorial excisions and emendations appear in the texts; and the letters are furnished with literary captions, often with conjectural dates (some of them clearly wrong), and occasionally with explanatory notes. From all this it would appear that the volume is actually a collection of letters selected and transcribed from Mrs. Warren's original drafts (which may or may not be extant elsewhere) with a view to printing them in a volume. To judge from the handwriting, the copies were made not long after 1800, though perhaps after Mrs. Warren's death in 1814. Texts of letters derived from this source (and some in the present edition are so derived) cannot therefore be considered reliable.
