418 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



of this study are published in Department Bulletin 341. An analysis 

 of the agriculture of farms in the cotton-growing States has also 

 been made, and the results have been prepared for publication. The 

 work in Ohio and Indiana, where studies are being made over a 

 period of years in the same areas, has been continued. Four years' 

 records are now available for the Ohio district and three years' 

 records for the Indiana district. Special attention has been given 

 to the determination of factors entering into the cost of the farmer's 

 living and what the farm contributes directly in the form of garden 

 products, milk, butter, eggs, etc. Farmers' Bulletin 635 has been 

 issued, and another manuscript has been prepared for publication. 



Analyses have also been made of several hundred farms in agri- 

 cultural districts where tenant farming is of primary importance. 

 Special attention has been given to a study of the underlying prin- 

 ciples of lease contracts and the effect of the various features of each 

 system of tenancy upon the income received by tenant and landlord. 

 A study of the tenant systems of farming in the Yazoo-Mississippi 

 Delta, also a study of systems of renting truck farms in south- 

 western New Jersey, have been published. 



FARM ACCOUNTS. 



The studies of the various systems of bookkeeping as worked out 

 by farmers and other individuals interested in this line of research 

 have been continued. Additional information regarding the prac- 

 ticability of certain of these systems has been compiled, and two 

 manuscripts are in course of preparation. 



FARM EQUIPMENT. 



The investigations on this subject have been confined to studies of 

 the character, cost, and adequacy of farm equipment in machinery, 

 implements, etc., with reference to farms of different types and sizes 

 in different sections of the country. A large amount of data has been 

 collected dealing with the farmers' experience with the various items 

 of farm equipment, and these results have been compiled for publi- 

 cation. Three bulletins dealing with the economic features of equip- 

 ment have been issued within the past year. These are Department 

 Bulletins 321 and 338 and Farmers' Bulletin 719. One other manu- 

 script has been prepared for publication. In studies on the equip- 

 ment of truck farms and greenhouses much valuable data has been 

 secured. Special attention was given to systems of heating green- 

 houses and the various factors affecting the cost of same. 



HISTORY AND DISTRIBUTION OF FARM ENTERPRISES. 



Substantial progress has been made in the studies on the history 

 and distribution of various crops and types of live stock in this 

 country. Large masses of geographic and statistical data have been 

 compiled for use in connection with an Atlas of American Agricul- 

 ture and an Atlas of World Agriculture. These data have been 

 collected from the various governmental agencies both in this de- 

 partment and in other departments in Washington. Cooperation
