58 THE MANOR once they were passed, the lord could enclose his common lands without any assent of the free tenants being necessary. This still •left him "the custom of the manor" to deal with, and this was generally a powerful force.1 The'' common assent" of the whole vill determined the dates at which various parts of the common should be open, or the number of cattle which each member of the manor might pasture thereon. Any infringement of these arrangements caused instant trouble and litigation. Neverthe- less, after these two statutes came into force, the lords gradually exercised more and more pressure, and the peasants were slowly deprived of their sometime powers and privileges. Where the commons merged into the wastes would be difficult to say. Some manors had only a limited amount of common strictly reserved for its own members, but in many parts of the country there were large tracts of waste lying between one vill and another. They were no-man's-land, and frequently so vast in extent that no very clear delimitation of ownership had ever been made.2 The vills surrounding them inter-commoned there- on at will. Such, for example, was the waste in the district of Whalley, where some 36,000 acres were used as pasture and woodland by various vills, and only 3500 acres were cultivated as arable.3 The waste of the New Forest was calculated at about 60,000 acres and fringed upon some twenty-one vills; that of Ashdown contained neady 14,000 acres, and being Crown land formed part of no manor. Epping Forest contained about 6000 acres and extended into seventeen manors, and so the list might be continued.4 These vast stretches of waste were utilised by all those vills which were near enough to do so and their rights run back into time immemorial. These vills inter-commoned in the waste in groups roughly determined by their geographical position. To take an example: Miss Neilson, in her introduction to A Terrier of Fket, has analysed with great care the arrangements made in 1 See, for example, A Terrier of Fleet (ed. N. Neilson), Ixxviii, and also below, p. 100, for a discussion of the force of custom. 2 See, for example, Bracton's Note Book, Case 1194, where the jury say a certain piece of waste " arapla est et magna, et nesciunt aliquas divisas quantum pertinet ad unam villam quantum ad aliam *', 8 Whitaker, Whalley, I, 233. 4 Dartmoor Preservation Association, I, xxviii.
