His Jewel of Office is the Plumb,… which is a stonemason’s instrument used for ascertaining the alignment of a vertical surface.

It symbolizes upright behavior among Masons.

The Junior Warden of a Masonic Lodge is the third in command of the Lodge. The Junior Warden sits in the South (symbolic of the position of the sun at midday) and is responsible for the Brethren while the Lodge is at ease or refreshment.

His position is similar to a Second Vice-President. The Junior Warden, too, may open the lodge if the Master is unable to attend the meeting.

It is the Junior Warden’s duty to arrange meals for the lodge, and, typically, the 2 Stewards act as his assistants in this responsibility.

Symbolically, it is also his duty to make certain that the members do not convert their refreshment into intemperance or excess.
