UPPER GONFWANA SERIES. 63 



Both the top and the base of the section are obscured by cotton soil, but 

 rather more than 2 miles to the west, sof tish gritty sandstones appear 

 from below the black soil. 



The beds included in the section have a general low dip to the east- 

 ward, but they show also several small local rollings. The angle of dip 

 ranges from 2° to 5° on the western side of the ridge, and 12° to 15° on 

 the eastern side, close to the village. The section represents a distance 

 of about 350 yards in length. 



The colouring of the beds on the ridge varies frequently and within 

 very short distances. Unfortunately, the shales are of no use economi- 

 cally, because of their breaking up into small pieces owing to the great 

 number of joints traversing the beds ; hence they are nowhere quarried, 

 though other hard shales, which break into great flaggy pieces, are largely 

 quarried at a little distance to the south. These latter unfortunately are 

 poor in fossil remains of all kinds. 



Fossils occur in all the shaly beds and are numerous in most, plants 



being rather less numerous than animal remains. The two classes of 



organisms constantly occur together in the same hand specimens. The 



most remarkable and about the best preserved fossils were obtained from 



the thin flaggy hard shale (No. 3 of the section) which, for brevity, I call 



the " fish bed/' From this came doubtless the very
