Padley's OR THE Cetiosaurus Quarry, Chipping Nor- 

 ton. — This classic quarry (52) is situated in the part of Chipping 

 Norton called " Tite's End " ; but now the once vast quarry 

 is practically abandoned, and cottage-gardens are sheltered in 

 its welcome depression. Now, this part of Chipping Norton 

 is better known as " The Quarry." 



The following details were obtained at the extreme 

 southern end of the quarry.
