for its flatness, paucity of streams, and barrenness 

 eencrallv The few and separate streams discharge their 

 taters into the Thames over the Oxford Clay, at four or 

 five points from north of "Old Man's Weir to Standlake. 

 The Charney Brook rises at Black Bourton, and after 

 passing Bampton enters the Thames at Charney Ford. 



There does not appear to be any definite system of 

 drainage over or from the Oxford Clay on either side of the 

 Thames, which is almost a part of the Bampton area, from 

 the confluence of the Cole near Lechlade, to near Oxford. 

 The extreme flatness of the Oxford Clay hardly admits 

 of a determinable watershed for the Bampton waters, but 

 which, nevertheless, at times must be considerable. 



The Watersheds of the Ock and the Thames run 

 parallel, that of the Ock on the south side of the River 

 ranges from Faringdon to High Woodbridge and Long- 

 worth The escarpment south of the Thame is composed 

 of the Corallian Rocks which release or pass to the 

 Thames over the Oxford Clay the waters of the few 

 streams that rise along the well defined belt and low 

 Iving plain of the Oxford Clay. North of the Thames the 

 higher ground and escarpment of the Cornbrash ranges 

 from Broughton to Broadwell, Alvescott, North Brize and 

 Witney ; the broad plain for the entire distance being 

 composed of Oxford Clay. 



As near as can be determined the following Rocks 

 occupy the Bampton area : 



The Great Oolite - - ^% square miles 

 „ Forest Marble - - 13/^ 

 „ Cornbrash - - 9% 

 „ Oxford Clay - - 35>^ "
