A sunmiary of the piincipal projects carried on during the i)ast 

 fiscal year under each of these divisions is given herewith. 



IMPROVEMENT OF EABM LANDS. 



A survey and plans were made by L. L. Ilidinger for nnderdrain- 

 ing the wet lands on the Berry School farm near Home, Ga. Pupils 

 •of the school, boys from the mountain districts, assisted in the survey, 

 and, with the superintendent of the school, w-ere instructed regarding 

 drainage and the methods of laying tile. For a part of the lines loca- 

 tion and grade stakes were set. The drains have been installed by the 

 students according to the plans. 



Attempts to drain farm lands in the vicinity of Chadbourn, N. C., 

 have heretofore met with but partial success. A survey was made 

 by S. H. McCrory, and plans were prepared for improving the nat- 

 ural watercourses and constructing new ditches to provide outlets 

 for about 3,200 acres of cultivated land. 



H. M. Lynde surveyed tracts on the plantations of S. G. Stoney 

 and J. P. Clark, in Berkeley County, S. C, and prepared plans for 

 the channels necessary to drain about 7,000 acres of wet lands. The 

 improvements will be made by the owners of the propertv, and wnll 

 serve as an example to other OAvners of similar lands in that part of 

 the State. 



The farm of L. S. Rogers, near West, Miss., was surveyed. For 

 the wet area there was planned a complete sj'stem of underdrainage, 

 supplemented by levees to prevent overflow by water from adjoining 

 lands. 



An experimental system of tile drainage was planned for 26 acres 

 on the farm of H. K. Knox, near Baton Rouge, La. The drains will 

 be installed by the landowner, to determine the feasibility of tile 

 ■drainage in the heavy alluvial soil of that vicinity. 



DRAINAGE OF SWAMP LANDS. 



During the w'inter a survey was made under the supervision of 

 A. E. Morgan to secure data for preparing a comprehensive scheme 

 to drain about 1,000,000 acres in the St. Francis Valley, in Arkansas. 

 The area includes about the eastern half of Craighead and Poinsett
