this scarp round, it is found that the dip gradually flattens out till the clilT 

 is reached at the northern end, where the beds are practically horizontal. On 

 following the scarp towards Packer's Creek the dip changes gradually, and 

 the inclmation is to the east at very low angles, and this gradual swing 

 continues till the fault is reached. This portion of the area thus exhibits 

 a synclinal arrangement.

It seems, therefore, that the beds have been subject to folding agencies 

 which have operated in a roughly east-and-west direction, and that under 

 their influences the middle block has been raised and cut oft' on its western 

 margin from the neighbouring blocks whose edges preserve their proper 

 alignment. This is the only sign that I observed of ;he beds having 

 been aft'ected by faulting. They show just that intensity of dislocation
