He told me that in the beginning of June, 1829, he received a letter from the Prophet asking him to come to Palmyra and convey him to his father's house, that he might there be able to work on the translation of the Book of Mormon. The journey required about three days each way, and it was necessary to put up at inns on the way. David having forgotten the names of the inns and their proprietors, Joseph looked through the seer stone and told him them. Oliver Cowdery made a note of these, and by inquiry on the journey found that the Prophet had stated correctly.
