Henry Harris comments on Joseph's "fortune-telling" with stone.
Henry Harris, Affidavit, in E.D. Howe, Mormonism Unvailed: Or, a Faithful Account of that Singular Imposition and Delusion, From Its Rise to the Present Time (Painesville: 1834), 251-252
Joseph Smith, Jr. the pretended Prophet, used to pretend to tell fortunes; he had a stone which he used to put in his hat, by means of which he professed to tell people's fortunes . . . I had a conversation with him, and asked him where he found [the plates] and how he come to know where they were. He said he had a revelation from God that told him they were hid in a certain hill and he looked in his stone and saw them in the place of deposit.
