 New York State College of Agriculture, at Cornell University, have 

 been published by that institution as Bulletin No. 377. 



LIVE-STOCK ECONOMICS. 



Part of the work for the past year has been a continuation of the 

 investigation conducted cooperatively with the Bureau of Animal 

 Industry. Three hundred and fifty additional records were procured, 

 making a total of practically 1,000 for the three years. 



FARM TENURE. 



Investigations on tenant dairy farms were continued, particularly 

 in Wisconsin and Illinois. In this work survey records were taken 

 on l.-)0 dairy farms, and a manuscript has been prepared for publica- 

 tion containing the results of this study. An inquiry into the method 

 of renting dairy farms also was made in Delaware and Maryland. 

 The material thus collected, when combined with that secured from 

 farm management surveys in other regions, will be used as a basis for 

 further discussion of tenancy on dairy farms. A study of tenancy 

 on wheat farms was begun during the year. As a preliminary step in 

 this work about 620 farm-tenancy factor sheets were prepared from 

 survey records taken mainly by the States Relations Service. Field 

 work in Kansas, Nebraska, South Dakota, North Dakota, and Minne- 

 sota supplemented this material with more than 400 farm survey 

 records taken on tenant wheat farms. 



During the year a bulletin was published on " The Systems of 

 Eenting Truck Farms in Southwestern New Jersey." A detailed 

 study was also conducted on cost to landlord and tenant of crops 

 raised on a New York share-rented crop farm. Two manuscripts 

 have been prepared for publication as a result of this study. A be- 

 ginning was made of the investigation of tenancy on stock farms. 

 About "300 tenant factor sheets were prepared from survey records 

 taken in various States by the States Eelations Service and the Iowa 

 Agi'icultural College. This material will be supplemented by field 

 work in Ohio, Indiana, Illinois, Michigan, Iowa. and_ Missouri on 

 tenant farms on which live stock is an important enterprise. 



In a study of lease contracts used in renting farms nearly 300 

 lease contracts in actual operation were examined, every State being 

 represented. The number of farm survey records studied with regard 

 to the essential features of a lease agreement was 2,900, being taken 

 on dairy farms, stock farms, general farms, and farms on which 

 T.-heat, potatoes, sugar beets, beans, tobacco, and other crops were 

 especially important enterprises. This study has served to show the 

 great variation in the lease contracts under different conditions. 



FARM PRACTICE IN ITS RELATION TO THE MAINTENANCE OF 



CROP YIELD. 



The work of the past year has been devoted very largely to the 

 tabulation, digesting, and writing up of results obtained in previous 

 field work, in particular a special study of certain highly productive 

 farms which were a part of the farm-management survey made in 

 Chester County, Pa., and a study of a 1,500-acre ranch in southern 

 California which had been cropped in sugar beets until the yields had
