The Mysteries of Free Masonry is a book about this infamous secret society, written by the New York businessman William Morgan, who was a mason himself, but turned against them. Morgan claimed to have been made a Master Mason while he was living in Canada, and he appears to have briefly attended a lodge in Rochester. After he was denied participation by members in Batavia, New York, he decided to publically expose secrets of Freemasonry. The book reveals and explains all the degrees conferred in the Royal Arch Chapter and Grand Encampment of Knights Templars—Knights of the Red Cross—of the Christian Mark—and of the Holy Sepulchre.
