S. G. W.: Most Worshipful Grand Master, I find the stone to be level. The Craftsmen have done their duty.
G. M.: R. W. Junior Warden, what is the proper implement of your office?
J. G. W.: The Plumb.
G. M.: What are its moral and Masonic uses?
J. G. W.: Morally, it teaches rectitude of conduct; and by it we prove our work.
G. M.: Apply the implement of your office to that portion of the corner-stone that needs to be proved, and make report.
The Plumb is applied to the sides of the stone.
J. G. W.: Most Worshipful Grand Master, I find the stone to be plumb. The Craftsmen have done their duty.
Grand Master (striking the stone three times with his gavel), says:
This corner-stone has been tested by the proper implements of Masonry. I find that the Craftsmen have skillfully and faithfully done their duty; and I do declare the stone to be well formed and trusty, truly laid, and correctly proved according to the rules of our Ancient Craft. May the building be conducted and completed amid the blessings of Plenty, Health and Peace.
