Free-warren confers the property in wild animals, and that property may be claimed (a) in the land of another, to the exclusion of the owner of the soil; for in ancient times persons summoned to parliament often obtaine from the Crown grants of warren in their demesne lands, comprising such parts of their manors or honours as then were, or might come into their actual possession; but the grant of warren(b) to a party in all his demsne lands, does not extend over the lands of freeholders of the manor, as such grants are construed strictly.
