It is not possible to ascertain from a mere record of the changes in the holdings precisely how many of these virgates and half-virgates there were in the manor of Winslow. But in the year of the Black Death it may be assumed that the mortality fell with something like equality upon all classes of tenants, 153 changes of holding from the death of previous holders being recorded in 1348–9. Out of these, 28 were holders of virgates and 14 of half-virgates. The virgates and half-virgates of these holders who died of the Black Death must have included more than 2,400 half-acre strips in the open fields; and adding up the contents of the other holdings of tenants who died that year, it would seem that about two-thirds of the whole area which changed hands in that memorable year were included in the virgates and half-virgates. It may be inferred, therefore, that about the same proportion of the whole area of the open fields must have been included in the virgates and half-virgates whose holders died or survived. Clearly, then, the mass of the land in the open fields was held in these two grades of holdings.[21] «They are held in villenage.» Thus much, then, may be learned from the Winslow manor rolls with respect to the virgates and half-virgates. Not only were they holdings each composed of a messuage and the scattered strips belonging to it in the open fields, not only did they form the [p029] two chief grades of holdings with equality in each grade, but also they were all alike held in _villenage_. They were not holdings of the lord's demesne land, but of the land in villenage. The holders, besides their virgates and half-virgates, often, it is true, held other land, part of the lord's demesne, as free tenants at an annual rent. But such free holdings were no part of their _virgates_. The virgates and half-virgates were held in villenage. Of these they were not _free_ tenants, but _villein_ tenants. So also the lesser cottage holdings were held in villenage. But the holders of virgates and half-virgates were the highest grades in the hierarchy of tenants in villenage. They not only held the greater part of the open fields in their bundles of scattered strips; the rolls also show that they almost exclusively served as jurors in the 'Halimot,' or Court of the Manor; though occasionally one or two other villein tenants with smaller holdings were associated with them.[22] «The villein holders, 'villani,' are '_adscripti glebæ_.'»
