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.
