DEAINAGE INVESTIGATIONS. 43 



J. R. Haswell formulated plans for improving McRae Branch, 

 Telfair Count}^ Ga. This branch is the main outlet for the drainage 

 of the flat lands in the vicinity, and its improvement, together with 

 the construction of necessary laterals, is essential as a preliminary 

 step to the complete drainage of the adjoining 1,650 acres of " flat 

 woods." 



The Belzoni Drainage District lies in the eastern part of Washing- 

 ton County, Miss. An extensive survey was made under the super- 

 vision of H. A. Kipp, who worked out plans for the reclamation of 

 90,000 acres in this district. The report on that project has been 

 issued in printed form.^ The drainage conditions in that district and 

 the corrective methods to be pursued are representative of many 

 similar areas in the Yazoo Delta which, though having rich alluvial 

 soil, are not available for cultivation without drainage. 



Lewis A. Jones surveyed and made plans for the drainage of 25,600 

 acres of seeped and overflowed bench land along the Elkliorn River, 

 in Holt County, Nebr. Ninety per cent of this area is at present too 

 wet for cultivation, being only suitable for wild hay. The damage 

 is due partly to insufficient channel capacity above the area under con- 

 sideration, but mostly to the seepage from the adjoining hill land, the 

 latter condition being the cause of almost uniform saturation of the 

 bench lands during- the spring and early summer months. 



There has been formed in Robeson County, N. C, the Back Swamp 

 and Jacob Swamp Drainage District. The territory included in this 

 district was surveyed under the supervision of S. H. McCrory, who 

 prepared detailed plans and estimates for the necessary drainage im- 

 provement. The report has been published as a bulletin of the office.- 

 The district contains 32,850 acres of wet land in which drainage con- 

 ditions are due to lack of efficient outlet, it being in this respect repre- 

 sentative of other large areas in eastern North Carolina. 



The Hopkins Drainage District, in Richland County, S. C, con- 

 tains some 24,000 acres which are not available for cultivation owing 

 to poor drainage outlets. The swampy condition results in malaria 

 to such an extent that white people are unable to reside continuously 

 in that section. The drainage improvements formulated by J. V. 

 Phillips, following a survey of the district, contemplate the complete 

 drainage of 3,500 acres of rich bottom land in addition to so improv- 

 ing the entire health condition of the district that it may be settled 

 by progressive people. 



In Charleston County, S. C, the McClellanville Drainage District 

 has been organized to include 4,450 acres, 1,245 of which are con- 

 tained in the permanently wet Little Wambaw Swamp. This area, 

 although naturally very fertile has poor drainage outlets, and on
