7. On Worked Flints from Glacial Dejjosits of Cheshire and the Isle of 

 Man. By J. Lomas, A.R.C.S., F.G.S., Pres. Liverpool Geol. Soc. 



Flints are not common in the glacial deposits of N.W. England. In one 

 or two places in the Wirral, however, and in the Isle of Man, they are fairly plen- 

 tiful. Sometimes they occur in the Boulder Clay, but more frequently in Glacial 

 Sands and Gravels. 



Some of the flints collected in these localities show undoubted signs of human 

 workmanship. 



Prenton, Birkenhecd. — The flints exhibited were collected from a recent exca- 

 vation near Mount House. Soft Bunter is seen on the S. and W. faces overlaid 

 by glacial sands. Between the two lies a bed of gravel containing small Lake 

 District and Scotch erratics up to fi in. diameter, along with broken Triassic 

 rocks, clay galls, and marine shells. In this gravel most of the flints have been 

 found. Others occur in the overlying sand, which also contains erratics and shell 

 frao-ments. Similar sand occurs at many places in the immediate neighbourhood, 

 and is usually overlaid by Boulder Clay. 



Spital Sandpit.— False bedded clean sand is seen, containing gravel and rolled 

 clav galls, overlaid by tough Boulder Clay. The flints occur both in the gravel 

 and JBoulder Clay. 



Capenhurst.—F]inta collected from gravel bands and clay in old sandpit 

 opposite church. 



MoUington, near Chester.— Lax^e sandpit, near high road, contains very little 

 cravel, and the flints mostly occur in the Boulder Clay which caps the section. 



Cliffs, N. of Ramsey, Isle of Man. — Glacial deposits in north of island well 

 exposed in the fine cliffs which extend from Eamsey almost to the Point of Ayre. 

 Near Ramsey, sands and gravels predominate, and these get successively more and 

 more clayey towards the N. 



In collecting the flints the author took great care to separate those found in 

 the talus slopes from those actually in the clays and gravels. The flints were 

 exhibited. 



8. The Glacial Sections at Moel Trifaen. 

 By E. Greenly, F.G.S., and A. B. Badger. 



Attention is called to the impending destruction of the best and clearest part 

 of the Moel Trifaen sections, and some lantern-slides shown to illustrate especially 

 the nature of the rock surface below the gravels and the relation of these to the 

 Boulder Clay. The terminal curvature in the slates is dwelt upon. This is well 

 marked, and is independent of the inclination of the surface, which does not exceed 

 3° to 4°. The laminae are bent over in a southerly direction. The displaced 

 laminse pass up into a breccia of angular and sub-angular fragments of slates which 

 underlies the gravels. 



It is hoped that an efibrt will be made while yet there is time to preserve an 

 adequate record, by photography and other means, of the phenomena displayed in 

 this classical section.
