EXPLANATION OF PLATE 12. 
Fig. 1.—Muck soil. The Everglades of Florida along the drainage 
canal, west of Fort Lauderdale. The soil here consists of muck to a depth 
of three to five feet, underlaid by sands which, in turn, rest upon oolitic 
limestone 1 . 
Fig. 2.—Prairie soil. One of the typical small prairies. View taken 
10 miles west of Sebastian. The soil consists of light colored sands to a 
depth of several feet, underlaid by clay or hardpan. The small prairie 
shown in the foreground is surrounded by palmetto flatwoods. 
Fig. 3.—Calcareous hammock soil. A view in Turnbull Hammock, one 
mile west of Daytona. Shell marl here lies at or very near the surface. 
The native vegetation includes cabbage palmetto and various deciduous 
hardwood trees. The calcareous soils are desirable, particularly for vege¬ 
table growing.
