a vital, but not so very demanding part if they have some botanical knowledge by recording (monitoring) sites easily visited at regular intervals, noting changes from year to year and month to month if possible. If a positive policy for hedgerows and verges is possible instead of the familiar "Don't touch!".... "Now look what you've done!" it might be based on the following: 1. ancient boundaries. 2. links between established reserves such as ponds, marshes or woods. 3. dramatic ecological contrast with the surrounding countryside or providing special habitats. There is another factor that has nothing to do with specialist interest or nostalgia for bygones. Over and over again, in all parts of the country, people who have made efforts to live in country areas are suddenly realising that the nearby countryside is not theirs. Places where they have a right to walk are diminishing to the narrow strips of land left between the efforts made in agricultural productivity and provision for motoring necessitated by their own demands. It is reassuring to recall that hedgerows and verges were originally created by man and, hopefully, could be man made again. BOOK NOTES I have recently come across three books which should be of interest to our members. The first of these is "Prehistory," by Derek Rose (Paladin, 1971, 80p). This has an introductory chapter which discusses the rise of prehistory, and the theories on the origin of man by which it was moulded and which in turn it itself moulded. This is followed Page 12
