North Island rising as a low flat dome, on the summit of 

 ■which stand Euapehu and Tongariro ; while the South 

 Island has also been elevated several hundred feet. And 

 this elevation appears to be still going on. 



This short sketch will, I hope, show you that New Zea- 

 land has had an eventful history, and we need not be sur- 

 prised if we still occasionally feel it to be somewhat unsteady.

A TRIP to the Kawekas by way of Puketitiri is a pleasure 

 not easily forgotten by any one fond of nature. These moun- 

 tains lie to the north-west of Napier, at a distance, speak- 

 ing generally, of fifty miles. The range is isolated, being 

 separated from the Euahine Eanges in the south by a long 

 low saddle, through which the Eiver Ngauroro passes, and 

 from the Te Waihiti and Eaukumara Eanges to the north 

 and north-east by a wide area of broken country, through 

 which traverse the head-waters of the Mohaka Eiver. 



The Kaweka Mountains and offshoots may be said to
