In this part of the field, or 
along the Paupugnee valley, these 
d CILE quartzites have, 
in  Paupugnee with the strata 
ioa both above and 
below them, been subjected to 
frequent though not very exten- 
sive dislocation, by which several 
sections of the country have 
been, by a succession of step- 
faults, thrown down to the south- 
wards. These dislocations are 
tolerably evident in the line of 
scarps overlooking the Paupugnee 
river, and more particularly at 
the. Annamalla pass, where the 
Mogamoor river cuts across the 
ridge; at the gap further south 
opposite Cotapully ; and again, 
in the shallower gap north-west 
of Vaimpully. There are other 
fainter traces of faulting between 
these points. Unfortunately these 
several lines were not clearly 
traceable into the great series 
of slaty shales and trappean rocks 
above the quartzites, mainly by 
reason of the covered-up condi- 
tion of the low country to the
