Here is a definition of a word found within Masonic ritual that is not common outside of our Lodge rooms.
Ashlar. To the uninitiated it is a stone selected by a mason and worked with tools to be made square for building purposes, or for pavement. Speculative Masons see the immovable jewels of rough ashlar and perfect ashlar, and apply the lessons of our progressive science. Students of Masonry may find more information in the collection of ‘The Newsletter of the Committee on Masonic Education’ (GL of Canada ‘Reflections’ newsletter): Vol 2, No. 2; Vol. 4, No. 1; Vol. 6, No. 2; Vol. 6, No. 4, Vol. 9, No. 3.
