I have made selections of all that is worth assaying, and 

 have sent the numbered samples corresponding with the 

 assay. The whole seems surface only, and, I think, gives 

 very good encouragement for furtlier search. — W. P.

The geological character of the country between Najwer and 

 the extinct volcano Euapehu, ritt Kuripapanga, has not, as far 

 as I am aware, been published, nor do I think that route 

 has been traversed by any one connected with the Geolo- 

 gical Survey. In January of the present year, in company 

 with Messrs. Petrie and Hamilton, I visited Euapehu for the 

 second time, and the following passing notes were taken 

 during my journey by this route : — 



The road might be described as running due west from 

 Napier along the parallel of 39° 30', and for all j^ractical 

 purposes it might be taken as being on the same j)arallel 

 as Euapehu and Egmont, the two highest and largest 

 extinct volcanoes in New Zealand. The distance between 

 Napier and Euapehu by road would be about 110 miles; but 

 as the crow flies the distance is about seventy, Euapehu being 

 about midway between Napier on the east and New Plymouth 

 on the west of the North Island. As far as Kunj^apanga, fifty 

 miles from Napier, the drainage belongs to the Hawke's Bay 

 river-system ; but beyond this the chief drainage is into Cook 

 Strait and the South Taranaki Bight. The country between 

 Napier and the Erehwon plateau resembles an inclined plane, 

 through which run river- valleys transverse to what was at one 

 time a great plain of denudation for most of the East Coast 

 country, extending from Poverty Bay southward as far as the 

 Wairarapa Valley. Generally it may be said that the road 

 to Euapehu and the volcanic district south of Lake Taupo by 

 way of Kuripapanga passes through the country drained by
