Peninsula towards the island of Kioa, the land slopes gradually 

 downward toward a depression which crosses the whole width of the 

 main peninsula. Southeast of the gap, the hills are eroded to late

 reeds, are in distinct contrast to the well-watered slopes clad with 

 verdure about Mbutha Bay. This area forms the second part of the 

 district. 



The rocks of this district cannot be exactly correlated with those

about Lambasa. The andesites of the Natewa peninsula are less 

 dissected than the Lambasa andesites and the interbedded ash gives 

 no evidence of having been laid down beneath the sea. These vol- 

 canic rocks are, therefore, probably not of the same age. Tt may be 

 possible that the more dissected andesites of Waikava Peninsula 

 corresponds to the Lambasa volcanics but most of the rocks of the 

 peninsula are believed to have been erupted since the main ujilift of 

 the island.
