This aggregation of plants resembles that of the swamps with calcareous water more than it does that of the strictly non-calcareous swamps.
ESTUARY OF THE SUWANNEE RIVER.
(PLATE 2 1 )
The Suwannee River takes its rise in Okefinokee Swamp and other swamps in the sandy pine woods of Southeast Georgia, and until it passes WVhite Springs it is a typical non-calcareous coffeecolored stream. In the remainder of its course quite a number of limestone springs discharge into it, which are said to make it quite clear at times.* I have, however, crossed it at seven different places
*William Bartram, who visited the Suwannee River (then known as the Little St. Juan) in the latter part of the 18th century, probably about where the northern corner of Levy County now is, spoke of it as "the pellucid river," saying of it among other things:- "The waters are the clearest and purest of any river I ever saw, transmitting distinctly the natural form and appearance of the objects moving in the transparent floods, or reposing on the silvery bed." (See the first edition of his Travels, pp. 224-226, 1791; or part 2, chapter 7, of any edition.) But Florida scenery seems to have wonderfully stimulated his imagination-as it has that of many another writer since his day-nd his descriptions of this state are unfortunately less reliable than those of other states mentioned in the same volume. It is possible, however, that for some reason this river carries relatively less calcareous water now than it did in Bartram's time.
