VOL. xvn. (I) INFERIOR OOLITE-SOUTH COTTESWOLDS 109 



There are several other quarries in the Freestones on this 

 hill for example, near the top of the lane leading up from 

 Fording Brook ; at the top of Nunnery Lane ; at Break-Heart 

 Hill ; and again in Hillside Wood. 



There are no beds between the Upper Tngoma-Gnt and 

 Freestones in this hill-mass. Everywhere the former rests upon 

 a water-worn and bored surface of the latter. 



The quarry at Break-Heart Hill is the one concerning the 

 date of the limestones in which Mr H. B. Woodward entertained 

 some doubt. He leaned to its Inferior-Oolite age, but referred 

 the beds to the horizon of Witchell's White Oohte instead of 

 to the freestones of MunhisoncB hemera.' Actually, there are 

 three feet of Upper Trigonia-Gni overlying about five times 

 that thickness of Freestone. 



Mr Woodward also referred to the Nunnery-Lane Quarry, 

 describing it as the " section south of Dursley."

The Upper Trigonia-Gvit is only thin here in comparison 

 with its normal development in the Mid Cotteswolds ; but 

 is quite typical and replete at the top with fragments of 

 Trichites. Its surface is oyster-strewn, and thereon rests a 

 marly layer correlative with the Upper Coral-Bed, which at 

 Stancombe Quarry has yielded quite a number of highly- 

 interesting echinoids. The upward succession is best made 

 out in the Stancombe Quarry, which is on the east side of 

 Hollow Combe. It is divided into two portions by a trackway.
