and Talchirs are completely cut out, aud the Mahadevas lowered to tlic 

 level of the gueiss. 



At the western extremity of the field a very pretty confirmation of 

 the existence of a fault, which is otherwise pretty evident, is afforded 

 by the occurrence of a small patch of Talchir boulder bed in the Supahi 

 river, [at the foot of the Maliadeva scarp. The full force of this 

 will be better appreciated by a reference to the map than by any 

 description. 



On the south' boundary of the field there still remain some Talchir

 and shales underlying a small area of Barakars, which is cut off by a fault, 

 gneiss being thrust up in the angle formed by it with the terminal 

 fault just mentioned. 



Talchirs are again seen at the base of the section in the Supahi, 



north-west of Purro, where the lowest bed ap-

Hence eastwards they are more or less distinctly traceable up to the 

 Purro stream, where a boulder bed rests naturally on the gneiss. 



Further east, though not exposed in the Koel section, Talchirs pro- 

 bably occur underneath the sandstone, as they are well developed in the 

 streams near Mundul, where liver-coloured shales are more abundant 

 Talchirs between Mun. ^^^^ elsewhere. There is also a considerable

thickness in a zone which laps round the base of the Mundul ranare. 

 from hence eastwards up to Hetlee^ where the boundary is faulted 

 and the Talchirs cut out.

At the eastern end of the field in the Kande hill station there is a

ing flat-topped ridges of a character most unlike that normally
