And, this section, J, is not at all exceptional in proving the 

 existence of a fresh-water bed, as in several places in the sur- 

 roundings part of the very same series may be traced in smaller 

 sections. Thus, for instance, at some distance to the north quite 

 a similar section was opened rendering in ascending order the 

 following layers arranged as follows: — 



1. Glay, finely laminated intercalated with quite thin sand- 

 layers. The clay has a blue colour and may be traced to the 

 depth of about one meter and a half without the section entering 

 the bottom of the series. 



2. Gravel, rather coarse and mixed with stones. This gravel 

 has a reddish-brovvn colour and in some places, at least, has a 

 thickness of half a metre. 



3. Sand, rather well assorted and containing remains of 

 trees. This sand has a reddish-grey colour and the thickness 

 of the sand-layer is about two or three decimetres. 



4. Decomposed or weathered material to the thickness of 

 about three decimetres. This layer is, however, levelled in the 

 foundation plane.
