In addition to 1he.se hardwood hammocks, there are also what are 

 known as cabbaiic palmetto and shell hammocks, terras that somewhat 

 overlaj) in their meaninfj. The eal)ha,2:e palmetto hammocks (Fi?. 110), 

 usnally rather low and flooded during the rainy season, when properly 

 drained, make excellent land for citrns groves. The shell hammocks, 

 so called becanse of the large amount of shells in the soil, are common 

 to the east and west coasts and are often palmetto hammocks as well. 

 Groves on these shell hammocks grow excellent fruit but have to be 

 handled with considerable care, as they are quite subject to Exanthema 

 or dieback.

The pine lands may be divided roughly into three kinds: (a) the 

 rolling, well-drained pine land, where the long-leaf pine, Finns palustris, 

 is usually the predominating growth (Fig. Ill) ; (&) the second grade 

 pine land, also somewhat rolling, where there is an undergrowth of 

 scrub oaks, and where the soil is frequently poorer; (c) the spruce 

 pine lands, which are composed of white sand containing an extremely 

 small amount of organic matter. A great many of the best groves in 

 Florida are grown upon the rolling pine lands. The second grade pine 

 lands are looked on with some suspicion, and groves are successfully 

 grown upon spruce pine land only with great care and expense. 



Flat woods means land that is more or less level and is usually 

 underlaid with elaj', harclpan or rock, and is likely to be temporarily 

 flooded during a part cf the rainy season. This land is apt to contain 

 a sparse growth of pines with an undergrowth of saw palmettos 

 (Sercnoa serrulala) and gallberry bushes {Ilex glahra) (Fig. 112). 

 Flat woods lands with clay subsoil are successfully used for citrus 

 groves, those with hardpan are usually avoided.
