Just about half the species noted in each of the two swamps 
(which are only 12 miles apart in a straight line) were common 
to both. 
Right at the mouths of these rivers the marshes with shrubs and 
herbs are more extensive than the wooded swamps, but in going 
up stream one would doubtless soon find the proportions reversed. 
The peat is several feet deep in the Escambia estuaries (its 
depth was not investigated at the mouth of the Yellow River), but 
probably still more impure than in the case of the Blackwater, and 
therefore of little value. 
EAST FLORIDA. 
The only fresh-water estuary in East Florida, besides the St. 
Marys River (which I have not examined on the Florida side) and 
a few creeks south of it, is that of the St. Johns River. The tides 
ascend this remarkable stream about to Lake George, giving it 
something like 100 miles of estuary. The following plants which 
I have seen in the river swamps between Palatka and the railroad 
bridge about five miles south of there are probably fairly typical 
of this whole lower portion of the St. Johns.
