geological rEATURES.

banks of the Morumbidgee River, to examine, 
with the accuracy I could have wished, either 
the immediate connection between these rocks 
or their gradual change from the one to the 
other. I was content to ascertain their actual 
succession, and to note the general outlines of 
the ranges ; but the defect of vision under which 
I labour, prevents me from laying them before 
the public. 
From what has been advanced, however, it 
will appear that the physical structure of the 
southern parts of the colony is as varied, as 
that of the western interior is monotonous, and 
we may now pursue our original observations 
on the soil of the colony with greater confi- 
dence. 
In endeavouring to account for the poverty 
of the soil in New South Wales, and in attri- 
buting it in a great degree to the causes already 
mentioned, it appears necessary to estimate 
more specifically the influence which the geo- 
logical formation of a country exercises on its 
soil, and how much the quality of the latter 
partakes of the character of the rock on which 
it reposes. And although I find it extremely
