Sylvan Springs, Ottawa. 
These springs are situated about two miles northwest of Hight 
Mile creek, a branch of the Marais des Cygnes. There is a ford 
at this point over the creek, and a drive has been cut through 
the timber, so that the springs are accessible. The springs are 
the property of the estate of S. E. Allison, and perhaps $100 
was spent in the improvements noted. The water of the main 
spring comes out of the rock on a level with the creek, but 
when confined it rises above that level, so that by carefully 
walling up and cementing about the spring an abundant sup- 
ply is retained. In order to obtain the water conveniently a 
platform has been built above the spring, and the water is 
brought to this platform by means of a pump. 
The flow is about 200 gallons per hour in the dryest weather. 
Within a few rods are several other springs, but the one of 
which the analysis has been made has the greatest flow. With- 
in the last five years the water has been hauled to Forest Park 
Ottawa, and placed in permanent tanks for use during the Chau- 
tauqua assembly, which meets for about two weeks in July of 
each year. The water has found quite an extensive use locally, 
but has not been shipped.
