At one locality, Nolan’s Creek, a vein of quartz contains copper 
pyrites, but not in sufficient quantity to pay for the working. 
In the sands of the Wando, minute rubies are abundant, and the 
quartz bands occasionally enclose good sized pieces of tourmaline. 
The remains of igneous outbursts exist here and there amongst 
the sedimentary strata, but on so small a scale that they might 
_ easily escape obser vation, Sometimes they are from recent basalti¢ 
overflows, and then the decomposed rock and ashes make a fertile 
soil, though of limited extent. At the Chetwynd, the bounding 
slaty rocks are highly metamorphosed, and thus converted into a 
brittle, dark-colored rock, crossed by regular bands of a lighter color, 
the characteristic cleavage being destroyed. At aquarry here, opened 
for the purpose of obtaining road metal, offshoots from the basaltic 
dyke are intercalated amongst this banded rock, which they have 
pushed both upwards and downwards, forcing it in some places to 
assume a horizontal position and in others to dip at varying angles. 
The workmen are obliged to excavate both rocks in cutting into the 
hill, but they are careful to separate the brittle and less useful one 
from’ the bluestone, which they are mainly in search of. The 
separation is easy enough, as both rocks run in well marked veins of 
varying width. In other localities, junctions of similar strata occur, 
without any metamorphosing effect being produced, as at Wando 
Dale, where a basaltic dyke is found in immediate contact with un- 
altered slates. 
At the Wando Gorge, there are two singular hills of igneous origin,. 
one on each side of the Wando, and the passage between is so 
narrow, that the passing traveller might well wonder what had become 
of the river, until on approaching, he finds that it runs in a channel 
between these two hills, of only a few yards in width. They were 
no doubt originally sw elling 2 mounds, connected at their base, but now 
cut through by the river W ando, which thus finds an outlet to the 
Glenelg, Sato which it flows. The hills are in a line with a low 
sclistose range, locally known as “The Hummocks,” extending from 
near Casterton to the table land at Brimboal.
