DAKOTA. 
Information as to mineral waters in Dakota is meager and the data ob- 
tained are insufficient for the compilation of a very complete list of the 
springs and wells that are known to be mineralized. The Territory has 
not been sufficently developed to have much attention directed to the sub- 
ject. In some of the southeastern counties are springs and wells in which 
the water is said to be chalybeate, but correspondence with persons
