_The next point after offenders are once apprehended, is to carry them before a proper magistrate, viz., a Justice of the Peace, and this leads us to say something of the nature and authority of that office. My Lord Chancellor, or Lord Keeper of the Great Seal, the Lord High Steward of England, the Lord Marshal, and the Lord High Constable, each of the Justices of the King's Bench, and as some say, the Lord High Treasurer of England, have, as incidental to their offices, a general authority to keep the peace throughout the realm, and to award process for their surety thereof, and to take recognizances for it. The Master of the Rolls has also a like power, either incident to his office, or at least by prescription. As to the ordinary constructors or Justices of the Peace, they are constituted by the King's Commission, which is at present granted on the same form as was settled by the Judges in the 33rd Year of Queen Elizabeth, by which they are appointed and assigned every one of then jointly and separately to keep the King's peace in such a county, and cause to be kept all statutes made for the good of the peace and the quiet government of the Kingdom, as well within liberties, as without, and to punish all those who shall offend against the said statutes, and to cause all those to come before them, or any of them, who threaten any people as to the burning their houses, in order to compel them to be kept in prison until they shall find it. As to the other powers committed to these justices, it would be too long for me to explain them, and therefore after this general Act, I shall go on to take notice of the manner in which the person accused is treated, when brought before them._
