WARREN, properly an old term of the English forest law, applied to one of the three lesser franchises, together with "chase" and "park," included under the highest franchise, the "forest," and ranking last in order of importance. The "beasts of warren" were the hare, the coney (i.e., rabbit), the pheasant and the
partridge. The word thus became used of a piece of ground pre served for these beasts of warren. It is now applied loosely to any piece of ground, whether preserved or not, where rabbits breed. (See FOREST LAWS.)
