Owing to the dearth of labourers for hire, and the loss of many of the services of their villeins, the lords found it very hard to farm their demesne lands. It should be remembered, too, that an additional hardship from which they suffered at this time was that the quit rents paid to them in lieu of services by tenants who had already become free were, owing to the rise in prices, very much depreciated. Their chief remedy was to let their demesne lands. The condition of the Manor of Forncett in Norfolk well illustrates the changes that were now going on. There, in the period 1272-1307, there were many free tenants as well as villeins, and the holdings of the latter were small, usually only 5 acres. It is also to be noticed that in no year were all the labour services actually performed, some were always sold for money. Yet in the period named there was not much progress in the general commutation of services for money payments, and the same was the case in the manors, whose records between 1325 and 1350 Mr. Page examined for his _End of Villeinage in England_.[121] The reaping and binding of the entire grain crop of the demesne at Forncett was done by the tenants exclusively, without the aid of any hired labour.[122] However, in the period 1307-1376 the manor underwent a great change. The economic position of the villeins, the administration of the demesne, and the whole organization of the manor were revolutionized. Much of the tenants' land had reverted to the lord, partly by the deaths in the great pestilence, partly because tenants had left the manor; they had run away and left their burdensome holdings in order to get high wages as free labourers. This of course led to a diminution of labour rents, so the landlord let most of the demesne for a term of years,[123] a process which went on all over England; and thus we have the origin of the modern tenant farmer. A fact of much importance in connexion with the Peasants' Revolt, soon to take place, was that the average money rent of land per acre in Forncett in 1378 was 10d., while the labour rents for land, where they were still paid by villeins who had not commuted or run away, were, owing to the rise in the value of labour, worth two or three times this. We cannot wonder that the poor villeins were profoundly discontented.
