all sizes, principally derived from adjacent hills, much rounded, 

 striated and polished. To the W. in the same section are beds 

 of stratified sands and gravels, with fragments of Tellina, 

 Astarte, and Balanus. These beds appear to have been 

 deposited against the mass of clay ; stones contained much less 

 rounded than in the clay. 21 species of Foraminifera were 

 found in the clay,t and 15 in the stratified sandy beds. 



Redeposited fossils found included a Carboniferous coral, 

 Gryphea incurva, Cardinia ovak's, ammonite, serpula, and 

 other fragments. One well-bored stone (chalk) was found and 

 another more doubtful specimen. Rolled fragments of gypsum 

 were obtained at the junction of the boulder clay and Trias. 

 300 boulders taken at random from three different depths were 

 all erratics. Several photographs of the cutting were taken. 



(N.B. — In the lists of Erratics, measurements are given in 

 inches unless otherwise specified. Boulders less than one foot 

 long not measured unless of special interest. Origin of rock 

 given, with the compass direction of parent formation added.
