The Working Tools
The Working Tools of Fellow Craft are the Plumb, the Square and the Level, and are thus explained:
The Plumb is an instrument used by Operative Masons to try perpendiculars, the Square to square their work, and the Level to prove horizontals; but we, as Free and Accepted Masons, are taught to use them for more noble and glorious purposes. The Plumb admonishes us to walk uprightly in our several stations before God and man, squaring our actions by the Square of Virtue, ever remembering that we are traveling upon the Level of Time to that “undiscovered country from whose bourne no traveler returns.”
