BAILEY. | Mineral Waters. 259 
Other waters here classified are rich in chlorids, and would 
be classified as dilute brines, if they did not contain hydrogen- 
sulfid gas. They possess, therefore, the therapeutic properties 
of both classes of waters. 
A sulfur water can be recognized not only by the odor, which 
is that of rotten eggs, but also by the deposit of yellowish-white 
matter (sulfur) in the spring. In some waters there is a black 
deposit of iron sulfid. A silver coin placed in the water soon be- 
comes black from the formation of silver sulfid on the surface. 
This group is represented by the following waters: 
Brookville, Saline county. 
Cherokee, Cherokee county. 
Columbus, Cherokee county. 
Sulfur Well, Cloud county. 
Fort Scott, Bourbon county, artesian well. 
Fort Scott sulfo-magnesian well. 
Girard, Crawford county. 
Haddon mineral well, Geary county. 
Madison, Sulfur Well, Greenwood county,. 
Pittsburg, Crawford county. 
Wakefield, Sulfur Well, Clay county. 
Brookville Well, Saline County. 
The water from a well some distance southwest of Brookville 
proves to be a strong sulfur water. It is clear and limpid at 
first, but after a time deposits a sediment. ‘The water contains 
much magnesia and iron, probably existing as chlorids; cal- 
cium, as sulfate and sulfid; sodium chlorid, silica, and free 
hydrogen-sulfid gas. This water may be mentioned as of 
considerable interest, and quite likely to be of value medicinally. 
The Cherokee Well. 
In the southeastern part of the state it was for some years 
difficult to obtain good water for domestic purposes. Shallow 
wells in the vicinity of the coal deposits yielded water that was 
very unsatisfactory, and the surface-waters were liable to be 
contaminated with the drainage from the mines. On this ac-
