The clay layer of section E is to the south-west overlapped 

 with a nearly levelled deposit of gravel or rather till. This de- 

 posit is of a grey colour with a dash of red, and the material 

 is coarse and rather unassorted as gravel niixed with clay and 

 containing numerous stones and blocks as well rounded as edged 

 ones. This till deposit completely corresponds with the till layer 

 of section B. 



The most interesting phenomena is, however, represented in 

 the far most complete section F. In ascending order we, in this 

 section, find a rather long series of numerous interesting layers. 



I. At the bottom of the series, that was not, however, fol- 

 lovved down to the firm rock, a rather well assorted material of 

 a grey or reddish colour was met with. This coarse gravel con- 

 taining rounded as well as edged stones seemed to represent a 

 fluvio-glacial deposit corresponding completely with the lowest 

 layer of section E. This deposit was only penetrated to the 

 depth of two or three decimetres, but the position of this layer 

 seems, however, to be sufficiently determined. 



II. This layer has a thickness of 30 cm. and consists of a 

 fine clay of yellowish-grey colour. This clay gives a strong 

 reaction to HC1 and is finely laminated. Clay layers of a thick- 

 ness of about one centimetre may be traced as separated by quite 

 thin layers of fine sand of a grey or rusty brown colour. 



III. This layer has a thickness of 5 cm. and consists of an 

 unassorted material of coarse gravel with clay and stones. It 

 gives a faint reaction to HC1 and it is of a grey colour with a 

 dash of red. 



IV. This layer has a thickness of 15 cm. and consists of 

 rather fine clay that is conspicuously laminated in thin layers 

 of only about one millimetre in thickness arranged in groups of 

 about one centimetre in thickness, each layer of clay being se- 

 parated from the other one by sand-layers thin as paper. The 

 clay has a yellowish-grey colour and gives a faint reaction 

 to HG1. 



V. This layer has a thickness of only one or two centi- 

 metres and consists of coarse gravel, presenting an unassorted
