§ 7. With the Norman conquest came a great revival of monastic life. The conquerors founded and heaped benefactions on new monasteries, or enlarged the possessions of Norman abbeys by granting them new estates in England. Many manors and more churches thus became the property of religious houses; and, where the property of a benefactor was widely scattered, a monastery might acquire a number of churches in many different counties. Thus the church of Kirkby in Malhamdale, in west Yorkshire, became the property of the abbey of West Dereham, in Norfolk; while a moiety of the tithes of Gisburn, in the same neighbourhood, belonged to the nuns of Stainfield, near Lincoln. These gifts, in the first instance, depended entirely on the free will of pious benefactors. The monasteries were naturally expected to present suitable priests to the churches; but this was left to their discretion. The logical result of these unconditional benefactions was that, as time went on, many churches were totally appropriated by monasteries: the income from the tithes, which should have served for the support of parish priests, was absorbed by the religious proprietors. Bishops recognised the evil; and towards the beginning of the thirteenth century steps were taken to check the control of monasteries over their subject churches. Archbishop Geoffrey Plantagenet in 1205 allowed the abbey of West Dereham to appropriate the fruits of the church of Kirkby in Malhamdale, but required them to reserve a stipend of ten marks yearly for a vicar. Such ordinations of vicarages became common within the next few years; and the great feature of the episcopate of Hugh of Wells, bishop of Lincoln 1209-35, was the provision of vicars, not monks, but secular priests with sufficient stipends, in the appropriated churches of his huge diocese. The monastery was usually allowed to take the greater tithes, _i.e._ the tithes of corn, for itself, the smaller tithes, or a sum in commutation of them, being reserved to the vicar. The study of episcopal registers shews that these provisions were sometimes evaded; and anyone who has made out lists of vicars of appropriated churches knows that frequently long gaps occur, in which it is probable that the monastery allowed the presentation to lapse unchecked; but the ordination of vicarages was in great measure a cure for the evil. However, during the thirteenth century, laymen still continued to present religious bodies with large gifts of property. The inroads which these benefactions began to make upon estates held in chief of the king were a menace to royal power. In order to provide a regular restraint upon the growth of ecclesiastical property, the statute of mortmain was passed in 1279. As a consequence of this measure, any man who wished to alienate land or churches to a religious corporation, was required to apply for royal letters patent. If it were found by inquisition that the property could be alienated without prejudice
