B. The "Kereru" is an old, well-established geyser, with 

 intermittent irregular action, sometimes throwing up water 

 40ft. high. Its water deposits a black sinter formation, quite 

 different in character from that of the others. I am therefore 

 inclined to think that, though on the same line of fissure, it is 

 not directly connected with them. 



C. The "Indicator" is a small hole. Gin. by 1ft., on the 

 common fissure. It generally plays intermittently for aii hour 

 or so before Pohutu, throwing a jet of steam and w^ater, at 

 an angle of 45°, to a height of 5ft. to 10ft. 



D. "Pohutu" is a perpendicular oval tube or funnel, 

 about 2ft. long by 18in. wide (formed in the fissure), worn 

 quite smooth. It is an intermittent geyser — the greatest in 

 Whakarewarewa, if not in the whole thermal district — throw- 

 ing a splendid column of water to a height of from 50ft. to 

 80ft., and lasting from one to two hours at each eruption. 

 Previous to September, 1888, it was very irregular in its action, 

 sometimes inactive for several months. 



E. " Te Horo." — This is a splendid pool of blue water, 

 about 15ft. diameter and 20ft. deep, with a kind of drain 

 leading out of it, thus : 



This pool is hydrostatically connected with Pohutu. It is 

 usually full of water to the line a (section, PI. XL.); but when 

 Pohutu is about to play the water becomes hot and boiling, and, 

 rising to the level of h, it overflows through the outlet. The 

 action then becomes more intense and furious, large volumes 

 of water being thrown up from 10ft. to 20ft. in height, and 

 falling back into the pool in beautiful showers, the large drops 

 sparkling like so many diamonds. It is a splendid sight, well 

 worth seeing. Sometimes this ebullition goes on for an hour 

 or so, when all at once the water in tlie tube of Pohutu 

 rises to overflowing and the eruption of Pohutu takes place. 



F. " Waikoroihi " is a small geyser-tube situated about 

 40ft. south of Te Horo, and a few feet higher up. It plays 

 almost constantly, throwing water from 5ft. to 20ft. high. 



G. " Wciiroa " is a splendid geyser, and the last southwards 

 in the fissure. When in eruption it somewhat resembles 

 Pohutu ; it is very irregular, being sometimes inactive for six 

 months at a time. 



Having noticed the great irregularity of action of the 

 different geysers, I thought that it must, to a great extent, be
