Hoover’s Spring, Onaga, Pottawatomie County. 
In the northern part of Pottawatomie county, about one-half 
mile north of the village of Onaga, which is accessible by the 
Kansas City, Leavenworth & Western railway, is a mineral 
spring owned and managed by Henry Hoover. The spring is 
in a depression east of the owner’s residence, and in the vi- 
cinity, both north and west, are hills overlooking the valley of 
the Vermillion on the east. The whole region is diversified by 
numerous hills and valleys, and is well watered and timbered. 
Hoover’s spring, which is 200 feet above the Vermillion, has 
been excavated twelve feet, to the clay. It was then walled and 
cemented to a point three feet above the floor of the spring-house. 
Clear water, which may be seen to bubble from the sand at the 
bottom, is conducted away to a cement reservoir about twenty 
feet distant. No attempt is made to utilize the water, except 
by local patrons and an occasional shipment of a few gallons. 
The flow is 180 gallons per hour. The composition of the water 
is as follows:
