THERE IS GENERAL AGREEMENT that the cost of parliamentary enclosure was high, and Turner has suggested that, whatever figures have been quoted, they are underestimates. Such high costs had important implications for the structure of rural communities, especially the survival of small owner-occupiers. 1 The Marxist view of parliamentary enclosure claims that high costs forced small owner-occupiers to sell out to their larger, wealthier neighbours, costs per acre being greater for small owners. 2 On the other hand, costs were very variable within regions at the same period. 3 Williams has shown that, in Somerset, costs per acre could vary by 100 per cent between different enclosures at the same period and on similar terrain, but there have been few attempts to identify and explain such variations. 4 In any parliamentary enclosure process costs can be divided into two main categories. First, there were public costs, ranging from the legal fees involved in putting a bill before parliament to making multiple copies of the award. 5 Secondly, there were private costs, such as ring fencing allotments, making internal boundaries and improving the land. The debate has focused on the cost of enclosing open-field arable and commons in lowland England where most of the enclosure was accomplished in the 1 M. E.
