Proceedings, &c, for 1882. 309 



Maori word " wliakaari" is " the mouth or place of vapour." All 

 action appears to have ceased on one side of the lake, and as far 

 back as the Maories can recollect it has been in the same state. 

 It is a remarkable thing that the escape of gas in these springs is 

 much more violent in the middle of the day than at any other 

 time. It gradually lessens in the afternoon, till it reaches a 

 minimum in the night. 



Mr. Ellery remarked that in all perennial and intermittent springs 

 this has been observed. 



In reply to a question from Mr. Ellery, Mr. M'lvor stated that 

 the quantity of mineral matter in solution was as much as 2 lbs. 

 to the gallon. After some few further remarks the discussion 

 closed.
