 will enable us to come close to the water's 

 edge. Now we must bend away from the 

 water and around the bog garden; now 

 we cross it on a stone causeway or rustic 

 bridge. 



All around the grass and flowers run right 

 out to the water's edge. This is the essential 

 point, and perfectly easy to attain. The
