survey of the district and prepared plans of the work to be done, 
together with an estimate of the cost. The survey was begun in 
August, 1912, and field work was completed in November of the same 
year. The following report presents a description of the district 
and of the drainage plan and a brief discussion of the problems in- 
volved in such reclamation. 
GENERAL DESCRIPTION. 
LOCATION. 
Black and Boggy Swamps drainage district is located about 75 
miles west of Charleston, S. C, 40 miles north of Savannah, Ga., and 
100 miles south of Columbia, S. C, in the southern part of Hampton 
County and the western part of Jasper County, S. C. (See figc 1.) 
It includes all the lands drained by Boggy Swamp and Black Swamp, 
together with the lands in the vicinity of Garnett that are drained by 
Church Branch, Hog Branch, and King Branch, all extending as far 
down as high water from the Savannah River; the area is 67,642 acres, 
or about 106 square miles. In shape the district is approximately a 
rectangle, 12 miles long northwest and southeast, and 9 miles wide. 
The Seaboard Air Line Railway and the Columbia-Savannah line 
of the Southern Railway traverse the district in a northerly and 
southerly direction, and on these railroads are situated the principal 
towns in the district, Scotia, Garnett, Furman, and Pineland. Other 
towns and settlements in the district are Brighton, Shirley, Robert- 
ville, Lawtonville, Staffords, and Goethe. 
TOPOGRAPHY. 
The district is situated 40 to 50 miles from the Atlantic Ocean, and 
thus lies within the Coastal Plain. There are in the neighborhood, 
including the Black and Boggy Swamps district, three distinct benches 
or levels paralleling the Savannah River. First, the river swamp 
proper; second, a higher level subject to occasional overflow, known 
locally as " savannas"; and third, the general elevation of lands in 
the district under consideration. The north, east, and west bounda- 
ries of the district are formed by natural watershed lines, but no such 
natural boundary occurs on the south. The general elevation of the 
lands in the southern part of the district east of the Seaboard Air 
Line Railway varies from 50 to 70 feet above sea level until the 
second bench from the river is reached, where it suddenly falls off 
about 25 feet. The foot of this slope has been determined upon as 
the district boundary. The southern part of the district west of the 
Seaboard Air Line Railway is much flatter and no decided slope is 
evident, the land rising gradually from the second to the third level, 
so that the southern boundary of the district should be more accu-
