GEOLOGY.— This Section will be officially represented by its Hon. Sees., 

 Rev. W^ Lower Carter, M.A., P\G.S., and Mr. J. W. Stather, F.G.S. 



Mr. J. W. Stather, F.G.S., writes as follows :— The geology of the Cave dis- 

 trict is chiefly interesting from its comprising a wide range of formations in small 

 compass. The Jurassic strata upon which South Cave is situated forms the strip o 

 country, under three miles wide, between the Trias of the IMain of York and ^th< 

 Chalk Wolds. The beds, which include the Lower, Middle, and Upper Lias, 

 Lower, Middle, and Upper Oolite, run roughly N. N.W. and S.S.E. and dip under 

 the chalk in an easterly direction. Between North Cave and the village of Cliffe 

 the Lower Lias forms a low escarpment, and the beds are well exposed in several 

 marl pits on the road side. The fossils found here include Liuiagiganlca^ Cardinict 

 listeti. Aninionites johnsloiii, Fkuroniya croivconiheia^ iModioIa Diininia, Osli-eayS^c

The Middle Lias is exposed in the neighbourhood of Hotham and North Cave, 

 Ijeing cut into by the roads going up the bank K. of these places. The Lower 

 Oolites of this district, which includes the Millipore or Cave Oolite, is well exposed 

 at South Cave 1-lailway Station. The fossils recorded are 7rigonia coiijnngens, 

 Lima pcdiniformis, Cricopora slaminea, &c. Of the ?vliddle Oolites represented 

 here, the Kelloway Rock is the most important member. It reaches a thickness of 

 more than forty feet and is seen in fine section in the cutting E. of South Cave 

 Railway Station. Fossils are very abundant, among which may be mentioned A. 

 niO'Jiolaris^ A, hivnigi^ B. owcnii, Gryphea bilobata^ Avicula braamburiensis^ 

 Iriovnia, Nafica^ Rhynchonclla socialis, iic. The Kimmeridgc clay and red chalk

Chalk near the Drewton Tunnel should also be seen, and St. Austin's Stone (a 



great mass of brecciated flint), at the head of Drewton Dale, is also worth a visit.
