Sub-Basin of the Sor Brook 



or the shenington, broughton, bloxham and 



adderbury streams 



The northern or Broughton, and most of the important 

 tributaries, rise near Blackwell Wood, close to the 

 north-western Watershed, draining the southern part 

 of the Edge Hills, then ranging by Shenington and 

 Shutford to Broughton, Bodicot, and Adderbury, entering 

 the Cherwell opposite, or west of Aynho. North-west 

 of Banbury the Ratley, Horley, and Drayton Streams rise 

 immediately south-east of the Edge Hills, uninterruptedly 

 traversing the Lower Lias Valley to Horley, when a 

 stream from the west meets the north and south stream 

 at Moore Mill, which continues its course by Drayton to 

 Broughton, and enters the Sor Brook. The Sor Brook 

 then flows entirely over the Lower Lias, and drains the 

 Middle Lias along its narrow bed for nine miles. 



The Great Copready and Long Compton Fault extends 

 for 17 miles, ranging from north-east of Banbury to 

 Broughton, Whichford, and Long Compton. The area 

 drained by the Sor Brook and its tributaries is about 

 60 square miles, 55 of which are occupied by the Middle 

 Lias, the remaining small portion being chiefly composed 

 of the Great Oolite, but much faulted. 



The Deddington Basin and Stream 



This considerable tributary enters the Cherwell from the 

 west, and runs parallel to and south of the Swere. It rises 

 due west at Pomfret Castle, and continues in a direct line 

 to its union with the Cherwell, between North Aston and 

 Somerton. Nine-tenths of the drainage in this basin is 

 from the Lower, Middle, and Upper Lias ; a strip of Great 

 Oolite along the southern side, from Pomfret Castle by
