PREFACE. 
The section of farm economics in the United States Department of 
Agriculture began to make a detailed study of farms in 1907; the object 
being to provide data — fundamental economic units — for effecting an 
economic farm organization. 
In making a working plan for a farm developing a cropping system, etc., 
in other words, effecting an economic farm organization, there is a certain 
adjustment of farm forces, dealing with the size of the farm, values, rela- 
tive profitableness of crops and live stock, yields, feed requirements of 
live stock, necessary equipment, available working time for operations, 
etc., which will produce maximum net returns.
