important positions: first the theory of personal subjection is modified in its legal application by influence in favour of liberty; and next this influence is not to be traced exclusively to moral and intellectual progress, but must be accounted for to a great extent by peculiarities in the political structure of feudalism. [Enfranchisement.] One point remains to be investigated in the institution of villainage, namely modes in which a villain might become free. I have had occasion to notice the implied manumission which followed from a donation of land to a bondman and his heirs, which in process of time was extended to all contracts and concords between a lord and his serf. A villain was freed also, as is well known, by remaining for a year and a day on the privileged soil of a crown manor or a chartered town[132]. As to direct manumission, its usual mode was the grant of a charter by which the lord renounced all rights as to the person of his villain. Traces of other and more archaic customs may have survived in certain localities, but, if so, they were quite exceptional. Manumission is one of the few subjects touched by Glanville in the doctrine of villainage, and he is very particular as to its conditions and effects. He says that a serf cannot buy his freedom, because he has no money or goods of his own. His liberty may be bought by a third person however, and his lord may liberate him as to himself, but not as regards third persons. There seems to be a want of clearness in, if not some contradiction between these two last statements, because one does not see how manumission by a stranger could possibly be wider than that effected by the lord. Again, the whole position of a freed man who remains a serf as regards everybody but his lord is very difficult to realize, even if one does not take the later view into account, which is exactly the reverse, namely that a villain is free against everybody but his lord. I may be allowed to start a conjecture which will find some support in a later chapter, when we come to speak about the treatment of freedom and serfdom in manorial documents. It seems to me that Glanville has in mind liberation _de facto_ from certain duties and customs, such as agricultural work for instance, or the payment of merchet. Such liberation would not amount to raising the status of a villain, although it would put him on a very different footing as to his lord[133]. However this may be, if from Glanville's times we come down to Bracton and to his authorities, we shall find all requirements changed, but distinct traces of the former view still lingering in occasional decisions and practices. There are frequent cases of villains buying their freedom with their own money[134], but the practice of selling them for manumission to a stranger is mentioned both in Bracton's Treatise[135] and in his Notebook. A decision of 1226 distinctly repeats Glanville's teaching that a man may liberate his serf as to
