SOLID CONSTITUENTS OF THERMAL WATERS. 



There are only two or three of the many constituents of thermal 

 waters to which we shall refer here in a brief consideration of their 

 sources. To take up each one would require more space than we can 

 spare. Silica is the -characteristic element in the waters of very hot 

 springs, especially in the geyser regions, not only in our own country 

 but in every other. This, therefore, is entitled to the first place in this 

 resume of the subject. 



SOURCE Ol'^ SILICA IN THERMAL WATERS. 



Tlie water found in geysers and hot springs being meteoric in its 

 origin, we must look to the rocks tlirough which it percolates for tlie 

 source of its mineral ingredients. Springs with siliceous deposits are
