CHAPTER XII. 
The Chlor-Sulfate Group. 
These are waters which retain many of the constituents of 
the chlorid group, yet contain sulfates in considerable abun- 
dance. They would have the laxative character of the strong 
sulfate waters mentioned in the previous group, but this would 
be somewhat modified by the presence of chlorids and often 
carbonates. 
This group is represented by the following waters : 
Carbondale, Osage county, Merrill spring. 
Great Bend, Barton county. 
Great Spirit Springs, Mitchell county. 
Leavenworth, Mountain Dew. 
Lincoln Springs, Lincoln county. 
Little River, Rice county. 
Marion, Marion county, upper vein. 
Overbrook, Osage county. 
Topeka, Shawnee county, Boon well. 
Topeka, Shawnee county, Phillips’s well. 
Merrill Mineral Spring. 
Southeast of the Carbondale well, on the opposite side of the 
street in a little depression, is situated the Merrill mineral 
spring. The flow of this is said to be 600 gallons per hour, 
and the water is supposed to come from a fissure in the rock 
several hundred feet in depth. It is seventeen feet down to 
this fissure, and a tile two feet in diameter is cemented tw this. 
By this means the water is brought to within eight feet of the 
surface, and from this point the water is raised by means of a 
pump and windmill and stored in a large cistern. 
There was a large bath and pavilion, for the convenience of 
visitors, but since their destruction by fire the only improve-
