Rather spar- ingly distributed throughout the district 3. LOWER WEY. With the exception of the narrow strip of land forming District I., this forms the north-western section of the county. About halfway along the south boundary the chalk widens out consider- ably and is covered by extensive beech woods. Further north and west are undulating commons and low hills of Bagshot Sand. The sandstone is soft and offers no support to rock loving species. On the commons occur the most considerable bogs in the county.
