A Lodge has six jewels; three of these are immovable and three movable.
The immovable jewels are the Square, Level, and Plumb.
The square inculcates morality; the level, equality; and the plumb, rectitude of conduct.
They are called immovable jewels, because they are always to be found in the East, West, and South parts of the Lodge, being worn by the officers in those respective stations.
The movable jewels are the Rough Ashlar, the Perfect Ashlar, and the Trestle-Board.[1]
The rough ashlar is a stone as taken from the quarry in its rude and natural state.
↑Such is the division of the jewels in the Lodges of this country; but in English Lodges the reverse is the case; there the rough and perfect ashlars and the trestle-board are the immovable jewels, and the square level, and plumb are the movable, because they descend from one set of officers to their successors.
