Little or no alluvial deposit occurs over the Evenlode 

 watershed. 



Owing to the excess of the Lower Jurassic Rocks 

 comprising the Valley of the Evenlode, and their impor- 

 tance to the Thames, I append the areas occupied by 

 the nine following divisions, and draining 167^ square 

 miles : 



At Woodstock the Evenlode receives the Glyme, which 

 rises in three small Liassic Valleys north-east of Chipping 

 Norton. These three sources or feeders form quite a 

 system of their own, cut out of the Great and Inferior 

 Oolites, and down to the Middle Lias, and drain an area of 

 10 square miles ; with this exception the Glyme and the 

 Darne chiefly unwater or drain the Great Oolite Rocks 

 only.
