THE WORLD'S GUYSER-REGIONS.

However, leaving the latter out of account, we find that in the adjacent 

 country both north and south of the park there are springs on the 

 same north and south line with the geyser-basins of Firehole River ; 

 and, if they are considered as a part of the same system, the length 

 of the line of thermal activity is about two hundred miles. 



As to the heights to which the geysers throw the columns of 

 water, there is probably but little difference between the three regions, 

 although the Yellowstone Park has, perhaps, a greater number which 

 erupt regularly to a height of one hundred feet or more. The records 

 of the New Zealand geysers are, however, somewhat deficient as to 

 data on this point. The following table presents some comparisons as 

 to this :

This list might easily be increased, but it includes all the principal 

 geysers. The bulk of the water in the New Zealand springs is so 

 great that in most cases the columns during eruption do not attain 

 great heights. 



* Three hundred and sixty feet is mentioned by Olafson and Povelson, but is proba- 

 bly an estimate. 



f A height of two hundred feet has also been recorded for one of the New Zealand 

 geysers. 



\ These arc two new geysers discovered in 1883 by Mr. Arnold Hagues, division of 

 the United States Geological Survey.
