226 FLORIDA GEOLOGICAL SURVEY-SEVENTH ANNUAL REPORT. 
survey, where they are associated with other fine-textured soils, and 
they occur also with the high hammock lands in the northern part, 
from York to Earlybird. There is also an area on the extreme 
northern boundary west of Standard. In the southwestern part of 
the area, in the vicinity of Lecanto, in Citrus County, there is a con¬ 
siderable body broken by other soil types. There are also a few 
small areas associated with the soils along the Withlacoochee River. 
The greater part of the type is flat to gently undulating. With the 
hammock lands, it occupies the flat or undulating areas between the 
high hammocks as extensions from those slopes occurring between 
the 70-foot and 90-foot contours. The area around Lecanto has con¬ 
siderable relief, being conspicuously rolling, ranging from 20 feet 
elevation in sink holes to slightly over ipo feet above sea level on 
the hilltops. All the areas are marked by sink holes of varying sizes 
and depths, caused by the removal of limestone by solution, the type 
resting upon limestone formations at comparatively slight depths. 
The Gainesville fine sandy loam has good drainage, the surface 
waters percolating either directly downward into the porous lime¬ 
stones or into the sink holes. The sandy soil mantle, because of its 
being underlain by clay, is fairly retentive of moisture. 
The subsoil of the Gainesville fine sandy loam is probably' for the 
most part, if not entirely, of residual origin, from the Vicksburg 
group of limestones. The rocks have weathered irregularly, and 
the more resistant parts protrude here and there above the surface. 
In some areas partially weathered limestone is occasionally found on 
the surface and in the soil mass. The surface sandy mantle is of 
doubtful origin. It is possible that much of it is water-transported 
material deposited over the residual clayey subsoil. In part it may 
also be residual, representing the siliceous parts of the parent lime¬ 
stone. 
This type was one of the earliest soils in the area to be cleared 
and cultivated. It had good natural drainage and the light soil was 
easy to cultivate and fairly productive. It is now devoted entirely 
to general farm crops and makes fair yields. It is a soil that would 
be well suited to trucking, but its location, with the exception of a 
few areas, is at present too far from shipping points. Having a clay 
subsoil, it would be adapted to citrus-fruit growing, providing the 
situation were right. None of the areas, except those along the 
Withlacoochee, lie near bodies of water. 
The type is partly forested, the growth being longleaf pine, fairly
