THE PREROGATIVE OF THE GRAND MASTER TO PRESIDE over every assembly of the Craft, wheresoever and whensoever held, is a fifth Landmark. It is in consequence of this law, derived from ancient usage, and not from any special enactment, that the Grand Master assumes the chair, or as it is called in England, “the throne,” at every communication of the Grand Lodge; and that he is also entitled to preside at the Communication of every Subordinate Lodge, where he may happen to be present.
