FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
LOCAL DETAILS 
BALDWIN. 
Baldwin is located on the Seaboard Air Line Railway nine¬ 
teen miles west of Jacksonville. The elevation is approximately 
86 feet above sea. Three wells have been drilled at or near Bald¬ 
win. The deepest of these located at the Atlantic Coast Line Rail¬ 
road crossing one-half mile north of Baldwin is reported to reach 
a total depth of 580 feet and is cased 511 feet. A second well 
nearby reaches a depth of 100 feet. A third well located at Bald¬ 
win reaches a depth of 92 feet. All of these wells are non-flow¬ 
ing although the water rises within a few feet of the surface. The 
distance at which the water stands from the surface in the deep 
well is not reported beyond the statement that the well is non-flow- 
irg. 
BAYARD. 
Bayard is located on the Florida East Coast Railway fifteen 
miles south of Jacksonville. The elevation of this place is approx¬ 
imately 22 feet above sea. Flowing water is obtained at Bayard, 
one well having been put down for the Cotter-Lucas Co. This is 
a three inch well reported to have been drilled to a depth of 280 feet. 
The water here will rise at least fifteen feet above the surface. 
JACKSONVILLE. 
The large number of wells occurring at Jacksonville precludes 
the possibility of listing or describing all. Probably not less than 
five hundred flowing wells occur in or near this city. 
The first flow obtained at Jacksonville according to the records 
of the city well was a light flow from a depth of 487 feet. A large 
flow, however, is not obtained until the drill enters the Vicksburg 
limestones at a depth of about 524 feet. After reaching the Vicks¬ 
burg the flow increases upon breaking each compact layer. At a 
depth of 632 feet the flow in the new city well was found to be one 
million gallons per day. At the depth of 980 feet the same well 
supplied a flow of two million gallons per day. 
The material penetrated in the drilling at Jacksonville for a 
depth of about 500 feet consists largely of clays, sandy clays, and 
sands with some fossiliferous limestone and some shell deposits. 
From about 500 to 524 feet the record shows considerable dense 
hard rock. After penetrating this stratum the limestones of the 
Vicksburg group are reached.
