became calcareous, when passing across the outcrop of the crystalline 



limestone ; fragments of this rock were here enclosed in a matrix of the 



usual flinty aspect, but which was found to be strongly impregnated with 



carbonate of lime. 



Passing from Dilheri village (see map) to Hinhotia, and eastwards

Breccia, to be struck with the aspect of many small hills 



which rise from the plain. 



They will be seen to affect a general east and west direction, and 

 sometimes to form pretty continuous ridges, parallel to the general line 

 of the bounding range of the valley. The beds of the schists along 

 here are nearly vertical, and these hills at first seem to be formed of 

 some of these vertical beds, harder than those around, and which from 

 this cause have resisted denudation, and remained as a hill while the 

 softer beds around were removed. It is soon found, however, that the 

 direction of the hill ridges is not that of the strike of the schist beds, 

 all the varieties of which may in turn be found at their base, but that 

 these ridges owe their existence to the breccia. This rock is always 

 found on the summit, it may almost always be traced up the east and 

 west sides of these hills, and sometimes across the flat ground from the 

 east of one to the west of another of them, while on the north and south 

 the schist beds only are seen, except that in most cases fallen masses of 

 the breccia greatly obscure the real structure of the ground, and in some 

 these are so numerous on the north and south slopes of the hills that 

 it is impossible to discover where the breccia is in place, and where only 

 accidentally present, as fallen from the higher part of the hill. 



Many other cases might be pointed out where lines of this breccia 

 mark the direction of disturbances which have affected the area occupi- 

 ed by the metamorphic rocks of our district, and these are shown on the 

 map by white lines. But the evidence of faulting derivable from such 

 cases is not confined to these older formations.
