BUREAU OF AGRICULTURAL ECONOMICS. 139 



A farm management survey of 450 farms in Chester County, 

 Pa., was begun. A somewhat smiilar study was made in this same 

 area in 1911. The present study was undertaken to determine 

 the changes in the organization and management of farms in this 

 area during the 12 years intervening between the two investigations 

 and to find out as nearly as possible the types of farming which 

 will be most jjrofitable there under present conditions. 



An investigation was begun, in cooperation with the South Caro- 

 lina College of Agriculture and Agricultural Experiment Station, 

 to determine the changes in the organization and management of 

 farms in that State which need to be made to meet the conditions 

 that have developed there since the advent of the boll weevil. 



STUDIES IN IDAHO, OHIO, AND FLORIDA COMPLETED. 



A three-year study of farming in the irrigated sections around 

 Twin Falls, Idaho, carried on in cooperation with the University of 

 Idaho, was completed. 



A six-year study of the management of citrus-fruit farms in Polk 

 County, Fla., and of the organization and management of truck 

 farms in Hillsboro County, Fla., was completed. 



A five-year study of the effect of tractors on the organization of 

 farms in northern Ohio was completed. 



PROGRESS MADE IN CONTINUATION PROJECTS. 



Four projects begun in previous years were continued. For the 

 eleventh consecutive year, farm business analysis records of about 

 60 farms in Washington County, Ohio, were secured ; for the second 

 year, a study of the organization of dairy farms in Vermont; also 

 for the second year, a study of dairy farms in New York State; 

 cooperation was continued with the State colleges of Arkansas, 

 Georgia, and Mississippi on combined research and extension work. 



A study of the organization of about 200 farms in the irrigated 

 district of the Yakima Valley in Washington was begun. 



INVESTIGATIONAL METHODS IMPROVED. 



Considerable attention was paid during the year to methods of 

 collection and analysis of material, with a view toward making the 

 results of farm-management investigations more useful. New sched- 

 ules were designed for use in most of the work begun and plans 

 were made for using more refined statistical methods. 



A special study was made, in cooperation with the Division of 

 Land Economics, to arrive at the best method of determining the 

 use value of land as compared with the sale value. 



Another special study was made in an effort to find the best' 

 method of determining the relative value of different classes of labor 

 used on the farm. 



FARM MANAGEMENT DEMONSTRATION WORK ASSISTED. 



In cooperation with the farm management demonstration work, 

 of the States Relations Service, a series of lantern slides for an 

 illustrated lecture on ^Vhy Analyze My Business was prepared; a 

 scenario for a moving picture showing the advantages of proper
