I.92 FLORIDA GEOLOGICAL SURVEY-SEVENTH ANNUAL REPORT. 
A part of the drainage waters reaches the Atlantic Ocean by w'ay 
of the Oicklawaha and St. Johns Rivers. Silver Springs Run is the 
main source of supply of the former. The run and the river are both 
navigable streams, and are used for passenger and freight boats. 
The Withlacoochee River is of considerable size, rising some distance 
to the south of the area. It flows in a northwest direction through 
the area. A part of it is navigable. 
Settlement within the area surveyed followed some years after 
that of Alachua County, in which settlement was begun in 1825. 
The early settlers came originally from the Carolinas and Georgia, 
and immigration from these States has continued even to the present 
time. In the last few years there has been some immigration of 
people from the Northern, Western, and Southern States, attracted 
by the mild climate and the agricultural possibilities of this as well 
as of all other sections of the State. The present population is thus 
an aggregation of the native stock of the State and of the different 
States of the Union. There is also a large negro population scattered 
throughout the counties represented in the survey. Marion County 
is one of the largest in the State and has a population of 26,941, 
according to the Thirteenth Census. Levy, another large county in 
areal extent, has 10,361 inhabitants, and Sumter and Citrus, much 
smaller counties, have, respectively, 6,696 and 6,731. 
Ocala, the county seat of Marion County, is the largest place, 
having a population of 4,370 within its corporate limits in 1910. 
It is an important railroad center and a prosperous business town, 
its business interests reaching into the adjoining counties. Its bank¬ 
ing business extends to all the industries of the section, including 
phosphate mining, lumbering, turpentining, and agriculture. 
In the western part of the area surveyed, on the Atlantic Coast 
Line Railroad, are the towns of Dunnellon, Hernando, Holder, and 
Inverness. They are in the phosphate mining district, and their 
inhabitants are largely engaged in this industry. 
On the Seaboard Air Line Railway, in the eastern part of the 
area, are the towns of Belleview, Summerfield, Oxford, Wildwood, 
and Coleman. Their interests are entirely agricultural. In addi¬ 
tion there are a number of smaller places on the different railroad 
lines that are shipping points for forest and farm products. 
The railroad facilities of the area surveyed are exceptionally 
good. Main lines of the Seaboard Air Line and Atlantic Coast 
Line traverse the area from north to south, with some smaller 
V.
