The doltfd lines indicate the courses of tlie original consequents flowing S.E. ; 



the arrows, the courses of present streams. 



the breaches high above the valleys of obsequent rivers 

 were cut by rivers which were extensions of the Thames 

 system ; that obsequent streams, such as the Chelt, Frome, 

 etc., which now flow in their respective valleys below the 

 breaches, are rivers of later date which have worked back 

 from the Severn, cutting out newer and lower valleys 

 beneath the floors of the original consequent valleys.
