II. — Further Explorm'iok of the Tt Newydd Cave, Tremeir- 

 CHiON, North Wales. By Eev. G. C. H. Pollen, S.J., F.G.S. 



IN a paper read before the Geological Society on December 15, 

 1897,^ the author gave the results of an exploration of 60 feet 

 from the old quarry. The work has now been extended to 150 feet 

 in this direction. In the upper portion a stalagmite floor has been 

 found in situ, completely sealing up the local gravels. Over this 

 were found five feet of clay with broken limestone, which is all that 

 is left to represent the strata in which the former roof of the cave 

 was situated. The whole is now overlain with boulder-clay, con- 

 taining many specimens of northern and. western drift, with striated 

 stones of more local origin. No trace of erratics or of glaciated 

 stones have been found in the lower cave materials. 



The cave has also been traced for 55 feet across the floor of the 

 quarry where it re-enters the rock, running in the direction of the 

 gully which separates it from the Ffynnon Beuno and Cae Gwyn 

 caves. In the lowest gravel of this pai-t a water-worn fragment of 

 the molar of JEqnus was found. The following succession seems to 

 be established for the contents of the cave : — 



(a) Cave nearlj-^ filled by torrents with local gravel containing 

 water- worn fragments of mammalian teeth. 



(6) Formation of stalagmite floor. 



(c) Last few yards of floor broken up and redeposited further 

 down the cave by floods, which completely filled lower portion with 

 sand and clay. 



(d) Denudation of rock above, destroying roof of upper portion 

 and depositing limestone debris on floor. 



(e) Introduction of striated stones and northern and western 

 erratics, which are deposited as one bed over the hillside. 



III. — On THE Exploration or Two Caves at Uphill, Weston- 

 super-Mare, oontaining Remains of Pleistocene Mammalia, 

 By the late Edward Wilson, F.G.S.^ 



(Commuuicated by Herbert Bolton, F.E..S.E.) 



QUARRYING operations now proceeding in the Carboniferous 

 Limestone near the old parish church of Uphill have led to 

 the discovery of two caves. 



The caves are about half-way up the face of the quarry, which is 

 100 feet in height. The floor of each cave is covered with a deposit 

 which varies from one to two feet in thickness. 



A typical section of the upper cave deposits is as follows : — 



ft. in. 



1. Deep purplisli-red, soft, sandy Marl, containing blocks of Limestone 4 



2. Greenish -yellow, soft, sandy Marl ... ... ... ... ... 1 2 



3. Greenish-drab argillaceous "Sandstone 5 6 



4. Limestone floor.
