The theory of the Book of Mormon is so closely akin to the theory of the origin of the American Indians in the lost tribes, as advocated before and about 1830 by such writers as Adair, Boudinot, Smith and Priest, that it would be very easy for the witnesses, who had not heard the "Manuscript Found" read for twenty years, to confound one with the other. Even to-day we hear intelligent people, some of whom have read the Book of Mormon, unthoughtedly speak of it as a history of the lost tribes. The important thing is that the writers of both romances have the ancient inhabitants (Israelites) coming from the city of Jerusalem and under the leadership of Lehi and Nephi.
