268 Report of Meetings for 1891. By Dr J. Hardy. 



Appendix. 



(A.) JVotes on the Surface Geology of North Charlton, Chathill, 

 Newham, etc. From the MSS. of the late George Tate, 

 F.G.S. 



North Charlton. 



After giving a Section of North Charlton Lime Quarry, where the 

 Limestone is now worked out, Mr Tate states, that uppermost lie the 

 Boulder beds and Gravel. This formation is red in colour ; occaaionally 

 of Clay, but generally porous. There are an immense number of blocks 

 of all sizes, chiefly local, of Sandstone, Limestone, Basalt, and a few 

 small Porphyries. 



The district around Charlton exhibits the peculiar features of the 

 Boulder formation — the hills rounded — combs scooped out— hills standing 

 out distinct : — all indicating the moulding action of water. The Forma- 

 tion is seen in the burn sides, and shows a large accumulation of Boulders 

 of local origin, embedded in a red gravelly Clay. The Clay is not 

 abundant or stiff. Large blocks of Sandstone, Limestone, and Basalt 

 appear ; — a few smaller rounded pebbles of Porphyry occur in the 

 gravelly parts of the upper portion. 



The most singular features of the district are, however, some grave- 

 looking hillocks in three of the fields ; and it is still an undecided 

 question whether they are natural or artificial. 



LUCKER. 



July, 1852. On the surface of a Quarry \ mile west from Lucker 

 Village, and at an elevation of at least 50 feet above the Railway line, 

 lies a band of Clay and Gravel, irregular in height, together of 10 feet 

 thickness. The Gravel is uppermost ; in the Clay are local lai-ge 

 Boulders; no polishings or scratchings — the deposit of the ordinary type. 



Chat Hill and Newham. 

 May 16, 1851. A little north of Chat Hill Farm House is the "Chat 

 Hill," which is a detached hill, about 200 yards long, 50 yards broad, and 

 50 feet high. It is steep on the W. side and N. end ; on the E. side it is 

 terraced looking, and rises by gentle slopes and irregular platforms. The 

 top is a flat surface, extending nearly the whole length and breadth of the 

 hill. The hill is a Boulder hill, somewhat clayey at the base, more 

 gravelly and sandy towards the top. The stones are rounded, varying in 

 size from small pebbles to blocks larger than the head. The rocks are 

 chiefly Sandstones and Limestones, with a few Basalts, and a very few 

 Felspathic rocks. On the west side is a pretty extensive flat or level 

 ground, which had evidently been covered with water — there also appear 

 markings on the hill indicative of changes in the level of the water.
