[Mrs. S. F. Anderick]
... Uncle Earl's farm was four miles south of Palmyra village, and his house was nearly opposite old Jo Smith's, father of the Mormon prophet. ... Jo was pompous, pretentious and active at parties. He claimed, when a young man, he could tell where lost or hidden things and treasures were buried or located with a forked witch hazel. He deceived many farmers, and induced them to dig nights for chests of gold, when the pick struck the chest, someone usually spoke, and Jo would say the enchantment was broken, and the chest would leave. Williard Chase, a Methodist who lived about two miles from uncle's, while digging a well, found a gray smooth stone about the size and shape of an egg. Sallie, Williard's sister, also a Methodist, told me several times that young Jo Smith, who became the Mormon prophet, often came to inquire of her where to dig for treasures. She told me she would place the stone in a hat and hold it to her face, and claimed things would be brought to her view. Sallie let me have it several times, but I never could see anything in or through it. I heard that Jo obtained it and called it a peep-stone, which he used in the place of the witch hazel. Uncle refused to let Jo dig on his farm. I have seen many holes where he dug on other farms."
