124 FLORIDA GEOLOGICAL SURVEY-'THIRD ANNUAL REPORT.
County. In both of these wells the water reached at a great depth is found to be too salty for use.
The Western Gulf Coast area begins at Carrabelle in Franklin County and probably extends without interruption to the western line of the State. This area, however, is very imperfectly known. The flow along this westward extension of the State is evidently due to the rapid southward dip of the formations exposed along the northern line of the State and in southern Georgia and Alabama. Both the Oligocene and the Miocene formations exposed along the Ocklocknee, Apalachicola and other rivers crossing western Florida from north to south, dip and pass from view in approaching the coast. It is doubtless from these or from later formations that the flowing water of this section is obtained. At Apalachicola the artesian water has a head bringing it only a few feet above the surface. The wells at this locality vary in depth from 350 to 620 feet. A number of deep wells have been drilled along St. Andrews Bay in Washington County. The artesian water in this section will rise several feet above sea level. One of the city wells at Panama City is reported to flow 13.02 feet above the surface, or about 15 feet above sea level. A second city well located on higher ground is non-flowing although drilled to a depth of 630 feet.
'Several wells, ranging in depth from I8I to 210 feet, have been drilled along Choctawhatchee Bay, in Walton County. A strong flow is obtained in this section. A well 210 feet deep, 3 miles south of Freeport, owned by the Baker-Wingfield Company. had a pressure when measured September 22, 1910, of 15 pounds, equivalent to a head of 34.65 feet above surface. Another well near by, 189 feet deep, belonging to the Choctawhatchee Lumber Company had a pressure on the same date of 12%,2 pounds, equivalent to a head of 28.87 feet above the surface. Both of these wells are located on low ground near sea level. A well I8I feet deep belonging to Messrs. J. C. Blackburn and J. N. McLain located on higher ground in the town of Freeport had a pressure of 6'2 pounds, equivalent to a head above the surface of 15 feet.
At Pensacola and generally along the coast in Escambia County good flowing wells are obtained. A well at Northrop, 1030 feet deep, belonging to Stephen Lee, is reported to have a head of 6o feet above the surface. At Muscogee a well 175 feet deep, belonging to the Southern States Lumber Company, is reported to have a head of :38 feet above the surface. A well on Bayou Grande near Pensacola belonging to Mgessrs. Stephen and W. F. Lee, is reported to be IOOO feet deep and to have a pressure of 24 pounds,
