Joseph Smith receives a revelation directing Oliver Cowdery and Hiram Page to sell the Book of Mormon copyright in Canada. Page says that he, Cowdery, Joseph Knight, and Josiah Stowell made the trip to Kingston, Canada, but were unsuccessful in their mission. David Whitmer remembered that Joseph Jr. was at the Whitmer residence in Fayette when the group returned . According to another source, the men left "early in 1830" and "went over on ice" . Because Page said the revelation was received in Manchester, it was probably dictated during Smith's January 1830 visit.
