Cropthorne a rounded boulder of Felstone measuring about 

 2 ft. 2 in. X I ft.' At Cropthorne, Lucy found a block of 

 syenite weighing 20 lb.* Several small grit boulders with 

 blunt edges have been found in the gravel pit near the Cemetery 

 at Stratford-on-Avon. 



Flints occur in great numbers in the gravels, and many 

 of them are worn and fractured. Chalk and unrolled flints 

 are found at Hatton,^ and blocks of flint of considerable size 

 and in fresh condition at Stratford-on-Avon, Evesham and 

 Cropthorne.* 



Striated white chalk and flint are recorded from between 

 Rugby and Lowmorton, and chalk gravel three or four feet 

 in thickness from Hilmorton.^ In a small field at Rowington, 

 Brodie found " httle bits of very hard chalk, rounded and 

 scratched, together with some Greensand."^ I have met with 

 no authentic account of the discovery of red chalk in the Avon 

 Valley. 



Boulder Clays are recorded as occurring at various places 

 in the Avon Valley. " Glacial Till " occurs at Exhall,^ Blue 

 Clay, with chalk, at Coventry and Berkswell,* Boulder Clay at 

 Rugby,^ and Laminated Clay (?Lake-mud) at Snitterfield and 

 near the New Inn on the Ridgway.'° No trace of Boulder Clay 

 equivalent to that found in the district round Birmingham 

 occurs in South Warwickshire" where it is replaced by sand 

 and gravel." 



Contortion in the Lias Clay at Bilton, near Rugby, was 

 noticed by the Rev. J. M. Wilson.'^ Furrows in the Lias at 

 Bredon Railway Station have been described by Mr L. Richard-
