ENTERPRISE. 
Flowing wells are obtained at Enterprise, along the shore of 
Lake Monroe, and in areas where the elevation does not exceed 
more than ten or twelve feet above the level of the water in the 
lake. The depth of the wells in this vicinity ranges from 20 to 
200 or more feet, the average depth being between 90 and 110 
feet. The water is hard and is charged with hydrogen sulphide, 
in some instances containing a large amount of salt. A well 
owned by Mr. William S. Thayer was drilled to a depth of 98 
feet. It is two inches in diameter and is cased 45 feet. The 
estimated elevation of this well is 15 feet above the level of the 
water in Lake Monroe. The water is reported to rise to within 
three feet of the surface of the ground. An analysis of the water 
from this well made in the office of the State Chemist showed 
it to contain 140 parts total solids to 1,000,000 parts water. The 
total solids are reported to be composed of calcium carbonate
