some of the slight elevations in the high pine land. They vary 
in size from only a few hundred feet to several miles. There are 
two groups of them: first, the large ones, which are really widen- 
ings of the Ocklawaha River, and second, the small, clear-water 
lakes. These latter are never very large, and the water contained 
in them is as clear as crystal. These are particularly numerous 
in the high pine land. They have no apparent inlet or outlet, and 
as a rule occur in deep depressions. How it is that the water re- 
mains so perfectly clear and limpid is hard to explain. Compared 
with our northern lakes, they contain little vegetation. /otamo- 
getons, Vallisneria, and other forms so common in the lakes of 
the North, are entirely absent, and are to be found only in the 
Ocklawaha River and the large lakes alluded to above. 
Another peculiarity about these clear-water lakes is their varia- 
tion in elevation. The case of Lakes Alfred and Irma will illus- 
trate this feature. They lie a little to the southeast of Eustis, and 
are only separated by a steep hillside some 500 or 600 feet long, 
Lake Imra being at the top of the hill. The difference in eleva- 
tion is about 65 feet. One or two small streams, rising in this 
hillside, flow into Lake Alfred. But in spite of this its waters 
gradually lowered during the entire summer, and when I left in 
September the lake was nearly dry. The waters of Lake Irma, 
on the contrary, remained at the same level, although it is consid- 
erably higher and would be expected to drain into Lake Alfred. 
As stated before, the flora of this section is very rich, and this 
fact is due to the exceeding variation in the physical features of 
the surrounding country. There are five well-marked areas, the 
flora of each one being different, and having certain plants pecu- 
liar to itself. These might be designated as: High Pine Land, 
“ Scrub,” Low Pine Land, “ Bayheads’’ and « Hammocks.” 
Of these the high pine land is the greatest in extent. The 
tall timber is composed entirely of the long-leaved or yellow pine, 
Pinus palustris. The trees have perfectly straight trunks, rising 
to a height of 50 to 75 feet, the branches all being borne near the 
top, leaving the trunks entirely naked. The two other prevailing 
trees are Quercus Catesbaei and Q. cinerea, the shining bright 
green deeply cut leaves of the former making a strong contrast to 
the narrow entire and grayish-green foliage of Q. cinerea. The
