 of February and March following I visited the volcanic area extending 

 from Ruapehu to Mount Tarawera. My purpose was to study volcanic 

 phenomena as presented by this almost imique extent of comitry, known 

 generally as the Taupo volcaiaic zone. The distance in a straight line is a 

 little over a himdred miles. Within this extent of country all aspects of 

 volcanic phenomena occur, from the active volcano, as Ngauruhoe and
