and finally to the same end-products, these two minerals composing in the 

 end the mass of the altered rock. 



The Vein-system. 



The gold-belt, which occupies a zone running nearly north and south, 

 passes through the broken foothill country of the Victoria and Brunner 

 Ranges, on the east side of the Inangahua Valley. It extends almost 

 continuously from the Lyell to Black's Point, near Reefton, in the 

 Inangahua Gorge, and, crossing the river, passes south as far as Snowy 

 and Blackwater Creeks, in the Grey River watershed. 



The belt thus indicated is, in its broader aspect, merely a portion of 

 the continuous reef-bearing zone of the West Coast. Thus, passing north- 

 wards, we come to the reefs at Mokihinui and on the Owen Goldfield, and

finally^ to Jthe^Golden^RidgeTdistrict, near CoUingwood. To the south, 

 wherever the belt of slates appears, we find reefs in the same line — in the 

 Taipo River and the Wilberforce. This belt of reefs is certainly irregular 

 in its course, but it cannot be geologically subdivided, as all the veins have 

 the same features, which will be described in detail under the next heading. 

 On the Reefton Goldfield, commencing at the north end, we find first 

 the Alpine Consols and other lesser-known claims at the Lyell. Passing 

 south we reach Larry's, where the Caledonian Mine is situated. Next, at
