278 FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
This list is of course not complete, but it probably represents 
the bulk of the vegetation of the heart of the far-famed and “mys¬ 
terious” Everglades. None of the species are particularly tropical 
(for they all range at least as far north as Georgia, and two or 
three of them evdn to Canada), or even rare. 
I did not have time to make a careful study of the peat here, 
but I was told that it averages about ten feet deep, resting some¬ 
times on sand and sometimes on limestone.* A sample of it from 
about a foot below the surface was taken near the canal about half 
way between the dredge and the mouth of the river (locality No. 
28). This, although it shows up pretty well in the analysis, may 
not be a fair sample of this, the largest peat deposit in the State. 
Farther out in the Everglades the proportion of mineral matter 
might be a little less. 
*A somewhat hypothetical section of the peat and underlying formations 
in this part of the Everglades, by Samuel Sanford, was published in the second 
annual report of this Survey, page 193.
