lower for bathing purposes. The analysis shows the upper vein to be a saline water, 

 and the lower a strong brine, much stronger than sea-water. 



Upper Vein. 

 Upon analysis the water is shown to contain the following substances, the result 

 being expressed in grams per liter: 



Calcium oxide 5341

Sulphuric anhydride 1.3736 



Carbonic anhydride (calculated) 2924 



Chlorine 5780 



Silica 0216

OIHNGAWASSA SPRINGS. 



These springs are situated about three miles north of Marion, Marion county. 

 Within a radius of a quarter of a mile there are at least 50 springs. Most of these, 

 however, are ordinary fresh-water springs. There are three or four that are strongly 

 impregnated with mineral matter. The analysis of one of these is given, as it is a 

 representative of the class. This is the so-called "North spring." A li^-inch stream 

 is constantly running from it. The temperature is 57.2° F. On the bottom and sides
