Polleonda range, flanking the Ontimitta valley, the quartzites are seen 
on the western steep slopes to be overlying slates with a thin series of 
limestones, &e., which must be the lower member of the Poolumpett 
series; while in the southern part of this range, or that flanking the 
north bank of the Chey-air, the same quartzites are covering slaty shales, 
&c., with limestones of the upper band. 
They show along the summit of this lofty range of hills running 
parallel with the north or left bank of the Chey-air; while the subjacent 
slaty shales and bands of limestone crop out from underneath them with 
a general undulating north-south strike. 
In their continuation as the Kaukul Conda ridge and its southerly 
prolongations down the middle of the Chey-air 
field, they are much folded, and have been let 
down in the Kaukul Conda* by a north-west south-east line of fauit, 
Kaukul Conda fault. 
which in the south-west flanks of this mountain gives the idea that the 
limestones of the Nundaloor valley are overlying the strata of the 
mountain. A section through this part of the country will illustrate 
this lie of the rocks :—

It is unfortunate that the wide bed of the Chey-air obscures any 
further trace of the fault; its position, if it continues southwards, is 
not again recognizable except by a much closer search than time would 
allow us to make. The undulating aspect of the quartzites in Kaukul
