Joseph Smith Jr. and his father Joseph Smith Sr. sign "Articles of Agreement" concerning the seeking of a lost Spanish silver mine near Josiah Stowall's property in Harmony Pennsylvania. Stowall had heard of Joseph Smith's ability to see hidden treasures and brought him 150 miles from Palmyra, New York to help locate the fabled treasure. No money was ever found and Joseph was later tried and convicted as a "disorderly person" for his "glass looking" activities with Stowall. However it was in Harmony that Joseph met Emma Hale, his future wife.
