2. Arenaceous deposit as in Arthur's Cave, with blue clay 

 intermixed, at the base of which and above the stalgamitic 

 floor, (which had not then been pierced,) in a crevice were 

 found molars and teeth of Mammoth, Rhinoceros, and Hyaena. 

 It is remarkable that in this cave the bones of the extinct beasts 

 were found overlying the stalagmitic floor, instead of being 

 covered by it as in Arthur's Cave ; but Mr. Stmonds gave it as 

 his opinion that there were evidences of the presence of an 

 upper thin floor of stalagmite, which had been broken up by 

 the miners in quest of minerals, and through which cause this 

 cave had suffered great disturbance. 



The third Field Meeting of the Club, on Tuesday, 16th July, 

 had for its object the examination of that portion of the Bristol 

 Coal-field which adjoins the 



MANGOTSFIELD STATION 



on the Midland Railway. 



It is probable that few indeed of the tens of thousands who 

 pass the Mangotsfield Station ever cast a thought towards the 

 great face of rock, seamed with a vein of impure coal, which 

 there presents itself to view ; yet does this rock tell a tale of 

 no ordinary import to him who has eyes to see and ears to hear. 

 The hill, of which this boss is the substructure, is called Rodway 

 HiU, and is itself a key to the geological history of the Bristol 

 Coal-field. It is a portion of the great mass of so-called 

 " Pennant" Sandstone, 1500 feet in thickness, which forms the 

 diaphragm between the upper and lower coal-basins of the 

 Bristol area— that of Coal-Pit Heath and Parkend to the north, 

 overlying the "Pennant;" while that of Kingswood to the 

 south lies below it. 



It was for an examination of this interesting district that on 

 the 16th July the Cotteswold Field Club met at the Mangotsfield 

 Station. Here they were joined by Handel Cossham, Esq., 

 and many other gentlemen, and under their guidance and that 

 of our colleague, R. Ethekidge, they proceeded to explore the 

 middle portion of the Bristol Coal-field.
