Warren

Chambers's Encyclopaedia, Volume 10: Swastika to Zyrianovsk and Index, p. 551

Warren is a place kept for the purpose of breeding game or rabbits. In its strict legal sense a right of free warren (extending to hares, rabbits, partridges, pheasants, and sometimes quails, woodcocks, and water-fowl) can only be derived by grant from the crown, and gives certain privileges to the warrener as to recovering game and destroying dogs which infest it.
