Joseph tells Emma about the "plains of the Nephites" and recounting Book of Mormon history while on Zion's camp.
Joseph Smith, Letter to Emma Smith, June 4, 1834, 57–58, Joseph Smith Papers
The whole of our journey, in the midst of so large a company of social honest men and sincere men, wandering over the plains of the Nephites, recounting occasionaly the history of the Book of Mormon, roving over the mounds of that once beloved people of the Lord, picking up their skulls & their bones, as a proof of its divine authenticity, and gazing upon a country the fertility, the splendour and the goodness so indescribable, all serves to pass away time unnoticed, and in short were it not at every now and then our thoughts linger with inexpressible anxiety for our wives and our children our kindred according to the flesh who are entwined around our hearts; And also our brethren and friends; our whole journey would be as a dream, and this would be the happiest period of all our lives.
