70 PROCEEDINGS OF THE COTTESWOLD CLUB 



Faults, as far as the Post House, south of Great 

 Rollwright ; these entirely bound the tributaries whose 

 sources are doubtless due to these parallel and extended 

 lines of disturbance. 



The Swere and its many small streams drain an 

 elongated basin in the Great Oolite and Forest Marble, 

 from Swereford to the south of Great Rollwright, as above 

 stated. 



East of Swereford to Wiggington, South Newington, 

 to Barford St John and Barford St Michael, to its 

 confluence with the Cherwell near the Paper Mill, the 

 river runs entirely between the two faults, the area 

 between them being little more than half-a-mile wide. 

 This complicated district is drained by another feeder to 

 the Cherwell from the west, parallel to the Swere, and 

 enters the main stream below Deddington, rising in the 

 Great Oolite at Pomfret Castle, close to the southern 

 water-parting of the Swere. 



This Deddington stream drains a well defined but small 

 basin in the Lower, Middle, and Upper Lias, bordered 

 on the south side by a narrow belt of Great Oolite, which 

 defines the area between it and the basin of the Dome. 



The numerous streams west and south of Banbury 

 from the Faulted district of Epwell, Tadmarton, Edgehill, 

 and Broughton, with those of Bloxham and Adderbury, 

 flow almost entirely over and drain the sandy beds of the 

 Middle Lias to the south of the Swere Valley, and 

 the long valley of Lower Lias drained by the Deddington 

 Stream is defined by the watershed between Dunstevv, 

 Great Tew, and Pomfret Castle, close to the southern 

 water parting of the Swere ; all south of this line, 

 to the Cornbrash, between Witney and Woodstock, 

 including the sub-basins of the Darne and Swere, is 

 occupied by the Great Oolite and Forest Marble as far as 

 Bladon.
