3. _The Wentworth Letter:_ The letter so designated, and from which the foregoing notes of this lesson are taken, was written at the request of Mr. John Wentworth, editor and proprietor of the _Chicago Democrat_. A friend of his, Mr. Bastow, was engaged in writing a history of New Hampshire and evidently desired to make some mention of the rise of Mormonism, and hence he enlisted the good offices of Mr. Wentworth to get a statement from the Prophet Joseph himself on that subject; and hence this letter was written. It is one of the most valuable of our original historical documents, and gives in concise form the very best statement possible of the rise, progress and doctrines of the Church up to the time it was written; namely, March, 1842. In addition to the statements concerning the Book of Mormon quoted in the foregoing notes, it was in that document that the summary of doctrines believed in by the Church appears, commonly known as the "Articles of Faith." The Wentworth letter entire is to be found in the Millennial Star, Vol. 19, pp. 117-120. 4. _Precautions taken in Printing the Book of Mormon:_ Nothing is said by the Prophet in his History of the difficulties that arose whilst the Book of Mormon was in the hands of the printer; nor of the care that was taken to prevent the manuscript falling into the hands of enemies of the work. It is proper, however, that these matters should be stated at this point. It appears that when the arrangements were completed with Mr. Grandin for printing the Book of Mormon, the Prophet went down to Harmony, in Pennsylvania. Before taking his departure, however, it was arranged: First: that Oliver Cowdery transcribe the whole manuscript; hence it came about that there were two manuscript copies of the Book of Mormon, the original, which was taken in charge by the Prophet after the publication of the book, and the copy made by Oliver Cowdery for the printer's use, and which finally was given by him into the custody of David Whitmer, with whose family it remains to this day (1901.) (Since the above was written the custodian of the Whitmer family has placed the Ms. in the care of Joseph Smith, son of the Prophet Joseph.) Second: that the copy made by Cowdery from the original manuscript only should be taken to the printer's, so that if that should be destroyed the original would remain in the hands of the Prophet and his associates, from which it could be replaced; and even this copy was supplied the printer in small quantities at a time, usually enough only for a single day's work of the printer. Third: that in going to and from the office whoever carried the manuscript--usually it was Oliver Cowdery--should always have a guard to attend him.
