If the privileged villainage of ancient demesne is founded on the same causes as villainage pure and simple, the distinguishing element of 'privilege' is supplied to it by the private interest of the king. This seems obvious enough, but it must be insisted upon, because it guards against any construction which would pick out one particular set of rights, or one particular kind of relations as characteristic of the institution. Legal practice and later theory concerned themselves mostly with peculiarities of procedure, and with the eventuality of a subject owning the manor. But the peculiar modes of litigation appropriate to the ancient demesne must not be disconnected from other immunities, and the ownership of a private lord is to be considered only as engrafted on the original right of the king. With this preliminary caution, we may proceed to an examination of those features which are undoubtedly entitled to attract most attention, namely, the special procedure which is put in action when questions arise in any way connected with the soil of ancient demesne. [Parvum breve de recto.] Bracton says, that in such cases the usual assizes and actions do not lie, and the 'little writ of right close' must be used 'according to the custom of the manor.' The writ is a 'little and a close' one, because it is directed by the king to the bailiffs of the manor and not to the justices or to the sheriff[156]. It does not concern freehold estate, but only land of base though privileged tenure. An action for freehold also may be begun in a manorial court, but in that case the writ will be 'the writ of right patent' and not 'the little writ of right close[157].'
