Due to the shortage of labor, landlords' returns had decreased from about 20% to about 5%. But some found new methods of using land that were more profitable than the customary services of villeins who had holdings of land or the paid labor of practically free men who paid a money rent for land holdings. One method was to turn the land to sheep breeding. Others leased their demesne land, which transferred the burden of getting laborers from the landlord to the lessee-tenant. The payment was called a "farm" and the tenant a "farmer". First, there were stock-and-land leases, in which both the land and everything required to cultivate it were let together. After 50 years, when the farmers had acquired assets, there were pure land leases. Landlords preferred to lease their land at will instead of for a term of years to prevent the tenant from depleting the soil with a few richer crops during the last years of his tenancy. The commutation of labor services into a money payment developed into a general commutation of virtually all services. Lords in need of money gladly sold manumissions to their villeins. The lord and lady of some manors now ate with their family and entertained guests in a private parlor [from French word 'to speak"] or great chamber, where they could converse and which had its own fireplace. The great chamber was usually at the dais end of the great hall. The great hall had been too noisy for conversation and now was little used. There were also separate chambers or bed-sitting rooms for guests or members the family or household, in which one slept, received visitors, played games, and occasionally ate.
