GEOLOGICAL Survey. 
During the past year Mr. Cox has been engaged for three months, from 
January to March, in an examination of Cape Colville Peninsula, more 
especially at the mining centres of the Thames, Coromandel, Waitekauri, 
Owharoa, Waihi, and Te Aroha. The most important results which he has 
obtained, lie in his determination of the stratification of the rocks at the 
Thames. He has shown there that the beds of the auriferous series consist 
of alternations of a moderately hard, compact, pyritous, tufaceous sandstone 
(tufanite of Dr. Hector); with less pyritous beds; a similar rock, which is, 
however, much broken up into pieces by joints; and a hard green dioritic 
rock, which is of true fragmental origin, but which passes at places into 
crystalline bands which are never continuous for any great distance. It is 
in the first of these that the reef has proved most highly auriferous, and 
while gold does occur in them while passing through the second class of 
country, they are not as a rule payable, and where the reefs traverse the 
hard rocks, they are absolutely barren. He has shown that several of these 
hard belts occur, and that where they are met with in the lower levels of 
the mines, the gold is cut off by them, but that other belts of auriferous 
country occur below, in which reefs have been worked. His work 
generally tends to show that, so far from the Thames being worked out,
