138 FLORIDA GEOLOGICAL SURVEY-I3TH ANNUAL REPORT

in size from lakes covering several square miles (most of these near the lake region) to small wet prairies and cypress ponds. Streams are, few and sluggish, and the rivers have extremely shallow valleys.
 Soils. There are no soil surveys of this region yet, except a narrow fringe at the extreme eastern edge, but the soils are. very similar in texture to those of the western division, and would presumably be classed mostly as fine sand. Chemically the average soil is probably less fertile than in the western division, especially in phosphorus (if the vegetation is a safe guide), but the Kissimmee River prairies are said to be much better than the flatwoods, and to produce some good crops without fertilizer.
 TVegctation. The principal vegetation types are palmetto flatwoods, prairies of several kinds, cypress ponds, low hammocks, swamps, fresh marshes, and a few patches of scrub. The prairies are several miles wide along the two largest rivers, and those along the Kissimmee (which the writer has not yet had opportunity to explore) are. said to have an abundant and varied native fauna and to be great cattle ranges, thus resembling some of the western plains Other and probably different prairies border the lakes near Kissimmee (fig. 26), and there are numerous small wet prairies in shallow depressions. The cypress ponds usually have narrow prairie-like margins, as stated in a preceding paragraph.
 The commonest plants seem to be as follows
