who, as a rule, couceritrate their attention on gold. The 

 establishment of the School of Mines at the Thames affords 

 every facility for acquiring a thorough acquaintance with the 

 mineralogy of the goldfields. It is to be regretted that recent 

 failures, and still more dishonest transactions, have brought 

 discredit on such a rich and extensive goldfield as Ohinemuri, 

 which must necessarily become some day one of the first gold- 

 producing districts of the world.

The Progress Eeport No. IS of the Geological Survey, for the 

 years 18b6-87, and published in the latter year, contains a

 counties of the North Island, by Mr. McKay, F.G.S., the 

 Assistant Geologist. Being interested in the district referred 

 to, and having also written somewhat upon portions of the 

 same district, I have read the report with a good deal of
