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 fig. 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-
