SOIL SURVEY OF THE OCALA AREA/ FLORIDA. 
239 
The orange-grove properties are not on the market, and the ham¬ 
mock land at Coleman is worth $250 to $300 an acre, being the most 
valuable land in the area surveyed. There is rarely any change of 
owners, however, as the land is so desirable because of the profit to 
be derived from it that only under extraordinary circumstances is 
it disposed of. The value has increased 400 or 500 per cent in the 
last 10 years. 
The individual holdings are small, the hammock being divided 
into 10-acre tracts and very few having more than this acreage. The 
whole area of a tract is devoted to the crops, the owners living on 
the sandy lands at Coleman, where the location is more healthful and 
the land has little agricultural value. 
The mechanical analyses of typical samples of the soil, subsoil, 
and lower subsoil of the Parkwood clay loam are given in the fol¬ 
lowing table:

PARKWOOD FINE SANDY LOAM. 
The surface soil of the Parkwood fine sandy loam varies consid¬ 
erably in depth, ranging from about 6 inches to 2 feet. It varies 
from a light fine sandy loam to a loamy fine sand, the immediate 
surface usually being black and somewhat mucky, especially in 
wooded areas, and the subsurface dark gray to gray. The subsoil 
begins as a plastic yellow silty clay, containing some marl and weath¬ 
ered limestone material, and grades into gray or nearly white marly 
clay, the content, of calcareous material increasing downward. There 
is a variation in which v the surface soil is black down to the clay
