king," was one of those reserved as specially pun- ishable in behalf of the king himself. These crimes were the original pleas of the crown but the king's peace by an easy process extended itself "until it had become an all-embracing atmosphere; " id. 402. That general peace which is now denominated the peace of the king or of the state, as the case may be, was in the early days protected only by the hundred court and the ealdorman. It is possible that medieval usage which applied to an inferior court the phrase the peace of the lord who held it, dates from the earliest period of the administration of justice. There is said to be some evidence that in the tenth century the phrase peace of the witan, was used, but no authority for the use of the term folk-peace; 1 Poll. & Maitl. 28.

The Lord Chancellor and the judges of the Queen's Bench Divison of the High Court are conservators of the peace at common law; they have all the common-law powers for the preservation of the peace which are possessed by other conservators, such as sheriffs and justices of the peace; they may command all men, whether private citizens, soldiers, or constables, to assist in the suppression of unlawful assembiles, and may arrest peace-breakers, by command, on view of the breach, or by their warrants.
