DRAINAGE OF BLACK AND BOGGY SWAMPS, S. C. 21 
CONCLUSIONS. 
Anyone who is at all familiar with the agricultural conditions 
existing in the Black and Boggy Swamps drainage district at the 
time this survey was made ; could not but be impressed with the 
need for artificial drainage. Large areas cf land are at present 
yielding no revenue whatever, yet all apparently have such natural 
qualities as would make them excellent farming lands if they could be 
relieved of excess water. The plans presented in this report provide 
for such relief, which should be secured at an average cost of about 
$5.50 per acre and would be worth many times that amount, although 
to realize the fullest possibilities cf the soil in many parts of the dis- 
trict tile drainage also should be installed. The ditches have been 
designed of ample depth to serve as outlets for the tile drains. 
Besides the financial advantage cf increased crop production due 
to drainage, there is the benefit to the general health cf the commu- 
nity, which is none the less real and important because it is less 
easily measured in money values. The decrease of malaria, which 
now exists in certain parts of the district, by removing the breeding 
places of mosquitoes, will make those parts more desirable for resi- 
dence and thereby add to their commercial value.
