THE GEANITE. 57 



of the main southern granitic mass^ high up on the western side of 

 the valley ; there being no apparent connection of the dykes with this 

 mass. The mutual influence of these dykes and the containing rocks 

 is very small indeed; the granite is less granular and less uniform than 

 elsewhere j but there is still plenty of free silica^ and without any sign 

 of a hornblendic mineral ; there is even less mica than in the main 

 granite. 



I have again in this section to point out the similarity with the 

 Behar rocks : they too are invaded by a granite, and apparently of later 

 date than the origin of their trappean rocks. 



N. B. — In the text I have endeavoured to give the local proper names in the 

 Jonesian form of transliteration, on the map the names are copied from the Topographical 

 Survey sheets.
