At Forncett and on the manors of the Berkeley estates commutation had little part in the disappearance of labor dues. The vacated land was leased in larger or smaller parcels at the best rents which could be obtained. This rent bore no relation to the value of the services formerly due from the land. The customary tenements which had been the units upon which labor dues were assessed were broken up, and the acres leased separately, or in new combinations, to other men.[71] At Forncett, as in the case of the Winchester manors where the services were commuted, the terms of the new arrangement can be compared with those of the old, and it is seen that the money rent obtained was less than the value of the services formerly due. The customary services were here valued at over two shillings per acre; the average rent obtained was less than one shilling an acre. The net pecuniary result of the change, then, was the same as though the services had been commuted for money at less than their value. Another method of reducing rents in this period was the remission of a part of the services due. Miss Levett notes the extent to which this took place on the Winchester manors, and suggests that the Bishop wished to avoid the wastefulness and inefficiency of serf labor.[72] She overlooks the fact that he failed to exact the money payment in place of the services for which manorial custom provided. It was a well established custom that in case work owed by the tenants was not used they should pay money instead. The amount of work needed each year on the demesne varied according to the size of the harvest, etc., but the number of days' works for which the tenants was liable was fixed. The surplus of works owed above those needed were "sold" each year to the villains. Frequently the number of works sold exceeded the number performed, although formal commutation of dues had not taken place. At Nailesbourne (1348-1349), 4755 works were due from the villains, but nearly 4000 of these were sold.[73] If the Bishop had merely wished to avoid waste, then, in ceasing to require the performance of villain services on his manors, he would have required the payment of the money equivalent of these services. When the services were excused, and the customary alternative of a money payment also, the change was clearly an intentional reduction in the burden of villain tenure. This fact makes emphasis upon the payment of money as the distinguishing feature of the changed relations between landlord and tenant in this period misleading. There was every precedent for requiring a money payment in the place of services not wanted. When, therefore, a great many services were simply allowed to lapse, it is an indication that it was impossible to exact the payment. It makes little difference whether the services were commuted at a lower rate than that at which they had formerly been "sold" or whether the villain was simply held accountable for a smaller number
