woods along the Withlacoochee River and in the Lake Tsala Apopka 
section. In the latter development it occupies flats standing only 
slightly above the waters of the lake or which extend into the shal¬ 
low parts of the lake and are covered by water only during the wet 
season. In the Tsala Apopka Lake section there are also' areas sup¬ 
porting a hammock growth of water oak and live oak, magnolia, and 
other hardwood trees and shrubs. The flatwoods support a thick 
growth of scrub saw palmetto, with some gallberry on the poorly 
drained spots, and broom sedge and wire grass on the better drained 
areas. The tree growth consists of shortleaf pine having a stunted 
appearance and frequently gnarly and twisted tops. There is a con¬ 
siderable area of this soil in the shallow ponds and prairies which 
hold water only during wet periods, at other times being* entirely 
dry, and which support a characteristic growth of dog fennel, with 
some grasses and sedges. These areas are indicated by symbol. 
The Leon fine sand is considered a poor and undesirable soil. It 
is too wet during rainy seasons and too dry in dry seasons. Because 
of the finer texture of this soil it is a somewhat better soil than the 
Leon sand. 
To insure success with crops on this land, irrigation is necessary, 
and with the methods of subirrigation in vogue in some parts of the 
State* by the use of tiles, which bring a supply of water as required 
and at other times afford drainage, agriculture, especially the pro¬ 
duction of special crops, could be made profitable. In addition to 
irrigation and drainage, however, success would depend upon the 
incorporation of a good supply of organic matter in the soil and the 
liberal use of complete commercial fertilizer or barnyard manure. 
A great variety of crops could be produced. Lettuce and celery are 
grown on similar soil in other sections of the State, also cucumbers, 
strawberries, and some other special crops. A little of the land is 
cleared and cultivated to the general farm crops, but the yields are 
low. There are areas along the’ Withlacoochee River that could be 
drained readily and irrigated, though probably artesian water could 
not be obtained. At present most of this soil is too far from the 
railroads to make the growing of special crops practicable and its 
value is very low. 
*See Circular No. 21, Bureau of Soils. This circular discusses briefly the 
uses and value of subirrigation in the trucking section about Sanford, Fla.
