The boundary comes south down the eastern boundary of Warwick Wood but half way turns sharply north north west going across the wood almost as far as Warwick Lane. It then turns sharply south west and goes down, and past, the boundary of the wood. It goes as far as the Common Watercourse and then turns east to follow it. After a while it turns south west in a kink, and then back south east for a while before turning again back on itself south west and going west for some distance. It then turns sharply south east again going towards a piece of woodland
