16 BUNDELCUND. 



in conformable bands to the exclusion of the limestone, the bond being 

 then generally chert. — The nature of these pebbles is open to doubt: 

 sometimes when so agglomerated, the amygdaloidal spaces are empty, 

 leaving the mass as a light, sponge-like shell of chert, sometimes the 

 cavities contain a little ochreous earth, as if the siliceous element alone 

 of the jasper had been removed, however, even in the most altered speci- 

 mens the derivative origin of the siliceous bond is apparent ; there are in 

 it small angular interstitial cavities coated by crystalline quartz. All 

 these beds lie quite undisturbed on a denuded surface of granite." 



The nature of the section and the relation of this peculiar rock to the 

 Tirhowan limestone is better exhibited in the line of hills of which the 

 second hill of Chutterkote is the most south easterly. 



"The Putrounda hill is about the highest of the lot: to four-fifths of 



its height it is of pink granite, in steep bare faces

and projecting masses — the sandstone comes in 



then quite undisturbed, actual contact not seen but about it got pieces of 



what is probably the bottom rock — a conglomerate in which felspar and 



quartz fragments preponderate, but in which are also small pieces of 



jasper and agate ; the whole in a coarse ferruginous sandy matrix. A few 



feet above the granite got a rather coarse fel spathic sandstone. Some of 



the beds are ripple-marked and flaggy ; at top the thick fine sandstone 



comes in." The conglomerate noticed here apparently belongs to the 



Vindhyans but has some borrowed materials from the siliceous breccia. 



The section on the hill over Burtpore is very similar to that described 

 but here there is probably some remnant of the lower formation, as I got 

 fragments of a siliceous vesicular rock, the cavities containing green 

 earth.
