reached a depth of 2,000 feet. The well was non-flowing and the 
water salty. No adequate record of this well was kept, and it is 
not known to what depth the well was cased, nor whether or not 
there was any attempt made to drill beyond and case off the salty 
water. The second well was drilled, in 1909-10, by S. O. Johnson 
and reached a total depth of 1010 feet. This well is cased about 
150 feet. It is non-flowing and salty. Two samples of water 
from this well have been received from Mr. Johnson. One is 
said to have been taken from the water near the top of the well: 
the other from near the bottom of the well. The first of these 
samples contains chlorine 2,340 parts per million parts water. The 
sample said to have come from the bottom of the well contains 
1358 parts chlorine per million parts water. 
THE SOUTHERN GULF COAST AREA. 
Flowing wells have been obtained in areas of low elevation 
at Tampa, St. Petersburg and elsewhere, along the Gulf Coast 
for some distance north of St. Petersburg. It is only near the 
sea level in this northward extent of the area that a flow is to be 
expected. In Manatee County, along the Manatee River, strong 
flowing wells have been obtained; some of them having a pressure 
of eight or more pounds. The wells in this county are used 
extensively for irrigation. In DeSoto County flowing wells occur 
at Punta Gorda, and along Peace Creek into Polk County. Some 
of the wells at Punta Gorda have a head of about fifty feet. In 
Lee County flowing wells have been obtained at Ft. Myers, along 
the Caloosahatchee River to Labelle, and in the interior southeast 
of Ft. Myers. In the well of A. P. Miller, of Ft. Myers, having 
a depth of 535 feet the water was found to be under a pressure 
of 17 pounds, giving it a head of 39 feet above the surface. The 
southward extent of this flowing area has not been determined. 
Approaching the southern limit the amount of salt in the water 
increases, certain of the wells toward the southern part of Lee 
County becoming too salty for use. The Vicksburg Limestone is 
probably the water bearing formation in Southern as in Eastern 
Florida. 
Whether or not flowing wells can be obtained in the Ever-
