“ This demesne land, originally held at the will of the lord, in course of time came to acquire fixity of tenure, and developed into the modern copyhold (see Manor) . It is from demesne as used in sense (a) that the modern restricted use of the word comes, i.e. land immediately surrounding the mansion or dwelling-house, the park or chase. Demesne of the crown, or royal demesne, was that part of the crown lands not granted out to feudal tenants, but which remained under the management of stewards appointed by the crown. ”
