378 ANNUAL REPOETS OF DEPARTMENT OF AGRICULTURE. 



A report upon agricultural drainage in Georgia has been prepared 

 for publication by the State geological survey, in cooperation with 

 the State geologist's office. 



SWAMP LANDS. 



The compilation of available data upon the amount of swamp and 

 other wet lands has been completed. According to the best informa- 

 tion obtainable, it is estimated that there are about 71,000,000 acres of 

 swamp land of various kinds, including tidal marsh, and 42,000,000 

 acres subject to overflow from streams. 



A report upon storm tides along the central Gulf coast, including 

 high-water records for the three highest of such tides, has been pre- 

 pared and rather widely distributed in mimeographed form. 



Surveys and drainage plans for six swamp districts have been made 

 and reports transmitted to the interested landowners. An equal 

 numJber of other similar areas have been- examined and preliminary 

 reports transmitted. 



IRRIGATION IN TllE HUMID REGION. 



Near Vineland, N. J., experiments have been begun to test the prac- 

 ticability of clay tile wound with wire and laid in concrete for dis- 

 tributing pipes in farm irrigation plants. 



RURAL ENGINEERING. 



FARM DOMESTIC WATER SUPPLY AND DRAINAGE DISPOSAL. 



Surveys were made and plans prepared for a gravity supply of 

 spring water, comprising collecting works, deliver}^ main, standpipe, 

 and distribution system. 



Drawings were made for a reinforced concrete storage tank 20 by 

 10 feet. 



Plans were prepared for utilizing the flow of an artesian well at 

 the kitchen sink and in a cooling tank beneath the kitchen floor. 



The manuscript and about 30 drawings are nearing completion 

 lor a comprehensive bulletin on " Farm Domestic Water Systems." 

 Methods of collecting, raising, storing, distributing, and purifying 

 water are described and illustrated. 



There was completed and published in the Yearbook (Yearbook 

 Separate 712), the article, "Sewage Disposal on the Farm." Plans 

 were drawn for a septic tank installation at Granville Test Farm, 

 N. C. 



Five examinations were made for the purpose of outlining systems 

 of sewers of sewage disposal installations. One lecture was given on 

 rural sanitation illustrated with lantern slides. Among the exami- 

 nations was the Marine Corps cantonment at Quantico, Va. 



Detailed information regarding the installation of sanitary meth- 

 ods of sewage and garbage disposal, the pumping, storing, and dis- 

 tributing of water as well as the development and protection of 

 sources of water supply has been furnished to many individuals 

 through correspondence and consultation. In some instances per- 

 sonal visits were made.
