In this interpretation the writer has been animated neither by a spirit of curiosity nor of animosity, but by a sincere desire to ascertain, if possible, from the recognized & official Masonic publications the true nature, essence & doctrines of the institution, and to present them to the reader in intelligible & unveiled language. The book is divided into four Parts entitled: Freemasonry a Religious Institution; Freemasonry is an Esoteric Institution; Masonic Hieroglyphs; Ethics of Freemasonry.
