iS4 MANORIAL ADMINISTRATION In order to aid them in their work it was necessary for the lord to give the chief officials the clearest account possible of what were the lands and people they had to control, and what things they might expect from the manorial population, in money, in service and in kind. Two main classes of documents gave them this information: the rentals or extents, and the customals. The rental or extent set out in the greatest detail exactly what was to he demanded of every single landholder on the manor. It first dealt with the freeholders, and this was a comparatively brief matter, for once their rent was paid little but an occasional service, such as attendance at the Manor Court on special occasions, or coming to oversee the workers during harvest was expected of them* The unfrec, however, were another matter: they had to render numerous rents and services, and often every detail of what was to be demanded of them was set out in the minutest fashion* And it did not follow that because one man did certain things his fellow would do likewise. Further, as we have seen, there were many groups in the manorial society, and the services of each of these groups demanded its own space in the extent. Once he had got this, however, the official knew what he might legitimately demand from everyone who held land of his lord. We have already noted the way in which the customal came into being. It embodied the many by-laws, as we may call them, which had gradually been evolved, and which, henceforth, re- presented "the custom of the manor". Both official and serf knew full well what these customs were, and after he had grasped what were a man's services as laid down in the extent, the wise official was careful to see how far (if at all) it was modified by anything laid down in the customal before he took any action. Our information concerning the manorial organisation comes from these two primary sources and also from the detailed accounts which the manorial officials were required to make yearly, and also from the Manor Court proceedings about which much will be said later,* In addition to this, we have a number of 1 These detailed accounts or campoti are classed in the Public Record Office as Ministers' Accounts, i.e. accounts rendered by an official appointed to minister affairs on the lord's behalf. They are discussed in detail below on pp. 186 ft. The Manor Court and its proceedings are dealt with in chapter vm, PP-195 ff-
