WATER. 



There is, probably, no part of this continent that can boast 

 of so large a number of bold, limpid springs, whose pure, cool 

 waters gush forth in such abundance to beautify and refresh the 

 land. Bryce's Spring, on the Niangua, is one of the largest. 

 It rises in a secluded valley where it forms a small pond and 

 then flows away a river. This river, just below where it flows 

 from the spring, is 126 feet wide, and has an average depth of 

 about one foot, and its velocity is a little more than one foot per 

 second. This immense spring discharges more than 126 cubic 

 feet of water per second, 455,326 per hour, and 10,927,872 

 cubic feet per day. The water is nearly pure, sustains about 

 the same temperature at all seasons, and shows no perceptible 

 fluctuations in quantity either in the dryest or wettest seasons.
