TWENTY-SIXTH ANNUAL MEETING. 41 



From an examination of these two analyses it can be readily seen that the 

 waters are much alike, the Great Spirit spring being a little stronger than 

 the other. This difference is noticed mostly in the sulfates and in the salt; 

 yet. for all tlTis, there is a remarkable similarity in the mineral salts and in 

 their relative proportions. 



A spring situated in the valley, where the water flowed off with little fall 

 into the river, and where there was a frequent opportunity for erosion at 

 high water, would not show the same tendency to build up a solid mound 

 about it that a spring would that issued from the rocks on high ground. At 

 any rate the analysis of this water may throw a little light on the method by 

 which the mound of the Great Spirit spring was built up, as the two are in the 

 same vicinity.
