Junior Warden (JW)
The Junior Warden’s jewel is the Plumb, an operative mason’s instrument used for determining the alignment of a vertical surface. It symbolizes upright behavior among Masons.
The Junior Warden is third in command amongst the Lodge Officers. He sits in the South, symbolic of the position of the sun at mid-day 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 his duty to arrange meals for the lodge, aided by the Senior and Junior Stewards.
Symbolically, it is also his duty to make certain that the members do not convert their refreshment into "intemperance or excess". This is a holdover from earlier days, which still remains as part of the Junior Warden’s job description, even though in most North American jurisdictions, alcohol is barred from the Lodge.
