of Maungatautari, in the gorge of the Waikato Eiver. So far 

 as my limited experience goes, it has appeared to me that the 

 general characters of the formations on the main range of the 

 King Country correspond to a considerable extent with those 

 described by Mr. Cox as containing the auriferous series at the 

 Thames. The tufaceous rocks are described as a composition of 

 igneous fragments, and are considered to be auriferous, espe- 

 cially when in the vicinity of slates, and when the tufaceous 

 character is due to the decomposition of highly indurated and 

 metamorphosed masses. It is probable that portions of the 

 masses forming the Hauhungaroa Eange are allied portions of 

 the rocks mentioned above, and products of the great volcanic 

 action of the Taupo zone, and appear very like some of the 

 formations of the Thames Goldfields described by Mr. Cox. 



In collecting together these notes, gathered rather promis- 

 cuously, I have endeavoured to do so in as concise a manner as 

 possible, and in such a form as to be useful in future investiga- 

 tions ; but they have run into greater length than I intended.
