Ellen E. Dickinson, based on an unknown source, reports Joseph claimed to have found stone while digging a well.
Ellen E. Dickinson, New Light on Mormonism (New York: Funk & Wagnalls, 1885), 30
While [Joseph] was watching the digging of a well, or himself digging it, he found, or pretended to find, a peculiarly shaped stone that resembled a child's foot in its outlines. It has been said that this little stone, afterward known as the "peek stone" and the "Palmyra seer stone," had been in the possession of Mrs. Smith's family for generations, and that she merely presented it to Joseph when he was old enough to work miracles with it; and that he hid it in the earth to find it again when it was convenient. As has been written, the "seer stone" was "the acorn of the Mormon oak."
