A NEW LONDON FLORA. 



KESTON COMMON 



Stands on higher ground and is higher at the upper than at the lower end, 

 which adjoins the preceding ; fronting the windmill is a hollow with 

 boggy ground extending downwards, and on the other side of the slope 

 beyond is a reservoir fed by a spring known as Cassar's Well ; this reservoir 

 flows into another larger and enclosed one. The spring is in fact the 

 source of the Ravensbourne rivulet. Bordering the common on one side 

 is Holwood Park, where are extensive remains of an ancient entrenched 

 town or camp. On the other side is a wood sloping to the south-west. 

 The common is overgrown with Furze, Bracken, and Ling.
