A six-inch well, drilled at this locality by J. C. Danielson, 
reached a total depth of 325 feet. The water in the well stands 
five feet from the surface. 
ST. PETERSBURG. 
Flowing wells are obtained at St. Petersburg, along the coast, 
the water rising 10 to 14 feet above sea level. A well near the 
dock is four inches in diameter and 100 feet deep. The water 
from this well rises 10 feet above the surface. Another well near 
the bay, about one mile southeast of St. Petersburg, was drilled 
480 feet deep. The water from this well rises about 10 feet above 
the surface and is salty. 
The city supply at St. Petersburg is obtained from one seven- 
inch and two ten-inch wells, variously reported at 135 and 235 
feet deep. These wells are located on the upland, about 31^4 feet 
above the level of the bay. When first drilled, the water is said 
to have stood 22 feet from the surface, but, after being used for 
some time, the water level was reduced to 36 feet from the surface. 
The following is an analysis of the water made by Dearborn Drug 
and Chemical Works, Chicago, Ill., December 11, 1911:
