The panel having been thus filled the court shall appoint one of their number as foreman of that body. After which the grand jury shall be sworn upon their oaths in due form of law touching their duties as grand jurors; the oath being usually administered by the clerk of the court. But where the duty of swearing the grand jury is not restricted to the clerk of the court, they may be sworn by any officer having power to administer oaths generally, under direction of the court.9
