Here's answer to week's question
(From page 2)
Elder Joseph F. Smith, speaking at the funeral of William Clayton in Salt Lake City Dec. 7, 1879, said that it was Clayton's pen "to a very great extent that we are indebted for the history of the Church - that is the history of the Prophet Joseph more particularly. . . . We have the journals which he kept . . . in the Historian's Office, from which - in connection with those of Elders Willard Richards and Wilford Woodruff and the Times and Seasons, a publication of the Church at that time - we have obtained the history of the Church during that period."
