(C) Fine bright red sand, very irregularly current-bedded 

 with intercalated layers of gravelly earth. 8 feet thick at N. 

 and 4 feet 6 inches at S. end, resting unconformably upon 

 boulder clay, and dipping towards S. No shells and no Fora- 

 minifera. 



(D) Boulder clay 5 feet 6 inches thick, dipping to N. by E. 

 at an angle of 24 . Extending southwards, becomes horizontal, 

 resting upon an apparently old surface of sand. Shells more 

 plentiful than in B, including — Leda pernula, Tellina balthica, 

 B alarms tulipa-alba ; and 13 species of Foraminifera. Boulders 

 striated and polished. Long axis N.E. and S.W. 97 per cent, 

 were erratics. 



(E) Fine red sand, like C. Base not visible. Greatest depth 

 exposed 4 feet, dipping to N. and S. No shells, and only 2 

 species of Foraminifera. 



This section is unlike anything else in the immediate vicinity, 

 the north-eastern half containing much boulder clay, which 

 extends N. of the railway line for some hundreds of yards. 

 Circular pellets of the clay with stones varying from 14 to 30 

 inches in diameter and more lenticular masses of gravel are 

 frequently found in the pure sand, which forms the south- 

 easterly half of the hill, attaining a depth of 35 feet. About 20 

 feet below the surface over half of this sandy area, imbedded in 

 the sand, was a layer of calcareous sandstone about an inch in 

 thickness dipping eastward. A cutting driven across the hill 

 encountered a mass of boulder clay, containing a pit of sand 

 60 feet wide and 12 feet deep. Much sand is exported for 

 moulding. 



A similar deposit of alternate layers of sand and boulder clay 

 occurs near Dundonald station, and thin isolated layers of clay 

 are not uncommon in sand-pits in Co. Down. Where the 

 boulder clay occurs, pits of sand about 12 feet in diameter are 

 not uncommon. 



The brick-clay bed at the opposite angle from the main 

 section described is dark, tough, brownish clay. Boulders 

 scarcer and smaller than in the beds already described, 86 per
