the outcrop of the Dakota and Permian. It obtains its waters 
from the Dakota. 
Cloud County. The sulfur spring at Concordia is on or 
near the outcrop of the Upper Cretaceous and the Dakota 
and draws its supply largely from the Upper Cretaceous. 
TERTIARY. 
Cowley County. The Arkansas City mineral well receives its 
supply from either the Permian or the Upper Carboniferous, 
probably the former. 
The Geuda springs are located on or near the outcrop of the 
Tertiary and Permian strata, and receive their waters largely 
from the Tertiary. 
Reno County. ‘The Hutchinson brine well, although situated 
on the Tertiary, draws its supply from the Red Beds or Upper 
Permian. | 
UPPER CRETACEOUS. 
Mitchell County. The Waconda springs are, in some respects, 
the most interesting natural phenomena known in the state. 
They are what might be called deep-seated springs, as they 
draw their supply through a considerable vertical distance from 
the saliferous shales overlying the Dakota. 
Ellis County. The Victoria spring exists in the Upper Cre- 
taceous and obtains its waters from the same. 
Russell County. The spring at Fay lies wholly within the 
Upper Cretaceous. 
Jewell County. White Rock and Omio springs receive their 
waters from the Upper Cretaceous. 
The Burr Oak well also drains the Upper Cretaceous strata. 
As previously stated, it is a rather difficult task to give any- 
thing like an exact geological position to the sources of supply 
of wells and springs, especially wells, as the depth is, in most 
cases, not exactly known, and, even if it were, an element of 
doubt exists.
