“I heard Joseph Smith[, Jr.] preach baptism for the dead; saw him baptizing for the dead in the Mississippi River. I heard him say, ‘Peradventure, the Ten Tribes were not on this globe, but a portion of this earth had cleaved off with them and went flying into space, and when the time comes when the ‘earth reels to and fro like a drunken man, and the stars from heaven fall,’ it would join on again.’”
