There is nothing particular to record with regard to the south- 

 ern portion. The northern portion is also divisible into two 

 parts — this time by a grass-covered slope, which marks a line 

 of fault. In the first part of this northern portion is seen 

 about 3 feet of the usual kind of Upper Trigonia-Gvit, with a 

 well-marked layer of oysters on top. Then comes a rubbly 

 deposit, which is of exceptional interest, in that — as already 

 mentioned — it has yielded a number of comparatively rare 

 echinoids. In the Coral-Bed equivalent, and in presumably 

 the basal portion of the overlying limestone-rubble, Terebratula 

 suhsphceroidalis , Upton, is by no means uncommon. 



At the extreme northern end of the other portion of the 

 quarry are bedded, unfossiliferous limestones, passing up into 

 more rubbly rock, which contains Clypeus Agassizi, Wright, 

 while this is followed by distinctly fossiliferous limestone — the 

 whole constituting the local Clypeus-Gvit. The White Oolite 

 is represented by greyish, rather sandy-looking limestones, with 

 few fossils except for Acanthothyris spinosa (Schlotheim) ; and 

 then, capping the section, are the Rubbly-Beds — quite typical 

 and abounding in Terebratula globata, auctt. non Sow., Holec- 

 typus depressus (Leske), etc. 



Returning to the combe at the northern end of the hill, at 

 the head of which a new house has been erected and a reservoir 

 constructed, a number of interesting exposures were available 

 when the pipe from the windmill in the bottom, near the Yew- 

 tree Inn, to this reservoir on the hill-top, was being laid. The 

 freestones were disclosed with the Upper Trigonia- and Clypeus- 

 Grits above. Then in a trial hole, occupying a position between 

 the Clypeus-Gvit and Rubbly-Beds, and therefore presumably 

 on the horizon of the White Oolite, were the interesting beds 

 detailed below. Here and there on Stinchcombe Hill it seems 

 probable that there are pockets of Fullers' Earth ; but this 

 deposit is best seen in a pond-side close to the road on Break- 

 Heart Hill.
