FLORIDA STATE GEOLOGICAL SURVEY. 
LESSIE. 
A deep well at Lessie, owned by J. R. Wilson & Company 
and drilled by D. C. Stafford, is reported to have a depth of 450 
feet. It is a two-inch well and furnishes an abundant supply 
of water. 
EOFTON. 
The well of J. W. Rodgers at Lofton was bored in 1906 and 
is reported to have a depth of 510 feet. It is two inches in 
diameter and gives a good flow, but the height to which the water 
would rise above the surface was not learned The water from 
the well is used for general domestic purposes and to supply the 
turpentine still. 
DUVAL COUNTY. 
LOCATION AND SURFACE FEATURES. 
Duval County joins Nassau County on the south, and is sepa¬ 
rated from it by the Nassau River and its tributary, Thomas 
Creek. The St. Johns River flows through Duval County. The 
surface drainage from this county is carried off largely through 
these rivers and their tributaries. 
The surface is in general flat or but slightly rolling. The 
surface elevation rises gradually from sea level. The highest 
elevation reached is found in the southwestern part of the county, 
where the “Trail Ridge” forms part of the boundary. A narrow 
strip along this part of the county exceeds 100 feet in elevation. 
With this exception practically all parts of this county lie below 
the 100-foot contour line, while much of the area lies below the 
25-foot contour line. 
The elevations in Nassau and Duval Counties have been ob¬ 
tained from various sources. An important line of levels extend¬ 
ing from Trout Creek across Nassau and Duval Counties in a 
southwesterly direction, made' during the summer of 1909, in con¬ 
nection with a preliminary survey for a ship canal across Florida, 
were kindly made available for this purpose in the office of the
