Phillips. — On the Volcanoes of the Pacific. 511 



Mount Eden — upon the isthmus connecting that city with 

 Onehunga. We all know the phenomena of our hot-lakes 

 district, White Island, and the Hanmer Plains. The Ker- 

 madecs are also volcanic, and liable to great earthquake 

 shocks. The longitude of these spots, roughly calculated 

 from the poor maps in a country library, is as follows : 

 Hanmer Plains, 172° 45' E. ; Tongariro, 175° 48' E. ; White 

 Island, 177° 12' E. ; Auckland, 174° 45' E. ; and the Ker- 

 madecs, 178° W. 



The distance from Tongariro to the Whakaari Volcano 

 (White Island) is 120 nautical miles. Over the whole dis- 

 tance, according to Dr. Hochstetter in his geology of New 

 Zealand, almost in the very line between these two active 

 craters, volcanic phenomena " seethe, bubble, and steam from 

 more than a thousand crevices and fissures that channel the 

 lava-beds of which the soil consists, a sure prognostic of the 

 still smouldering fire in the depths below ; whilst numerous 

 fresh-water lakes — of which Lake Taupo is the largest (twenty 

 miles in diameter)— fill up the large depressions of the ground. 

 This is the lake district so famous for its boiling springs, its 

 steaming fumaroles, solfataras, and bubbling mud-basms." I 

 give the extract now, in order that members may fully reahse 

 the phenomena close to their doors — along a distance of 120 

 miles — before I carry them to the evidences of much gi-eater 

 phenomena in the Pacific. 



Mount Egmont is also an extinct crater : longitude 174° E. ; 

 height, 8,280 ft. 



Almost every volume of our Transactions contains valuable 

 references and tabulations by Sir James Hector of earthquake 

 phenomena, to which I refer members ; and I would also refer 

 them to the excellent earthquake papers by Professor Hutton, 

 Mr. A. McKay, Mr. Field, and other contributors. We live 

 in New Zealand in the midst of unaccountable earth-move- 

 ments, as it were ; but it may be that by arranging for the 

 establishment of seismitic stations in the neighbouring islands 

 of the Pacific — to which I am about to refer — we may begin 

 to understand the cause of these movements a little more 

 clearly than at present. In one of his papers* Mr. McKay 

 placed the centre of the 1888 disturbance of September and 

 October in the Amuri district (Hanmer Plains), at Glen Wye, 

 the force of the shock diminishing in all directions from this 

 particular part, and Sir James Hector agreed. Perhaps by 

 throwing into one paper all the facts at my disposal of Pacific 

 phenomena a wider range for earth-movements will be granted 

 by geologists.
