gravel, clay, and stones and forms a true till. This layer 

 exactly corresponds with the upper gravel- or till- layer of 

 section E. 



X. This layer has a thickness of 8 — 10 cm. It consists 

 for the main part of sand but this is only assorted in a rather 

 slight manner and mixed in part with clay and gravel and con- 

 tains rounded and edged stones of the size of a nut. It gives 

 a faint reaction to HC1. The colour of it is grey with a faint 

 dash of red. This material is, no doubt, a morainic one in- 

 fluenced by fluvio-glacial or marine water. 



XI. This layer consists of clay of a yellowish-grey colour 

 and finely laminated. It is in part mixed with sand, but gives 

 reaction to HC1. The thickness of this layer is only 7 mm. 



XII. This layer consists of sand, that is rather slightly as- 

 sorted and mixed in part with clay and gravel containing small 

 stones. It gives a faint reaction to HG1. The colour of it is 

 grey with a faint dash of red. The thickness of this layer is 

 only 4 mm. 



XIII. This layer has a thickness of 9 cm. and consists of 

 sandy clay of a yellowish-grey colour and finely laminated. It 

 gives reaction to HG1. 



XIV. This layer has a thickness of only 2 mm. and con- 

 sists of a finely laminated sand, very fine and of a reddish-grey 

 colour. It gives reaction to HG1. 



XV. This layer has a thickness of 5 cm. and consists of 

 clay of a yellowish-grey colour and finely laminated; in part it 

 is mixed with sand but gives reaction to HCl. 



XVI. This layer has a thickness of 15 mm. and consists 

 of sand of a grey or rusty brown colour. It gives a faint reaction 

 to HCl. 



XVII. This layer has a thickness of 18 cm. and consists of 

 clay that in the lower part of the layer gives a faint reaction 

 to HCl, but in the upper part of the layer gives a rather strong 

 reaction to the same acid. This clay is very fine-grained and 

 not a single stone is to be observed. It is of a yellowish-grey 

 colour and it is finely laminated presenting layers of a thickness
