pumped the head is reduced, stopping the flow in the other well. 
The 270-foot well has brackish water. 
The Clearwater Ice Factory has three wells, 46, 52 and 80 feet 
deep. They are all cased 30 feet and the water is reported to 
stand 26 feet from the surface. These wells are located on high 
ground, the difference in elevation being probably sufficient to 
account for the difference in head between these and the city wells. 
DUNEDIN. 
Flowing wells are obtained along the coast at Dunedin. The 
wells range in depth from 55 to 120 feet. C. B. Bowden has a 
six-inch well, 98 feet deep and cased 70 feet, in which the water 
stands 20 feet from the surface. This well is used as a public 
supply. T. J. Zimmerman has a well, at this locality, 68 feet deep, 
in which the water stands 12 feet from the surface. W. C. McLain 
has a flowing artesian well, about two miles north of Dunedin. 
This well is 202 feet deep and is estimated to flow 10 gallons a 
minute. This is the northernmost flowing well in this county.
