NERBUDDA DISTRICT. 239 



looking from the east or from the west, at Muttardeo, or Persakote hills, 

 they appear to be very steep cones, or in some points of view almost 

 vertical pillars of rock ; looked at however from the north, or south, the 

 profile is very different. They then appear as flat topped hills, with slop- 

 ing sides, and the whole range to which they belong is much less picturesque 

 in outline when seen from this, than from the former direction.* 



At the base of both these hills and close under the foot of Muttardeo, 

 the soft green muds of the Talcheer group are found. 



The observer will on the ground be struck by the fact that the con-

schist series, and he will probably be at first led to the conclusion that 

 this part of the Talcheer basin, was, when those beds were originally 

 being deposited, very nearly identical in outline with the existing valleys 

 along the south side of the area now occupied by the rocks of the group. 

 He will perceive that the lowest of the Talcheer beds are often here ex- 

 posed as in the Rawundeo section, (see Fig. 5, p. 152,) and he will see that 

 the direction of the strike of the crystalline rocks closely coincides with 

 that of their boundary, even where this boundary is most clearly rectili- 

 near; and however remarkable this straight line direction may be, it thus 

 seems accounted for satisfactorily by referring it to the original form of the 

 basin of deposit, a form impressed on that basin by the structure of the

crystalline rocks. Still much, perhaps most, of this boundary is certainly 

 faulted, as is seen to be the case in many places along its line. Fig. 18, 

 shows a case of this, many instances similar to which might be adduced.
