numbers of work units reflect the importance of this factor. Repre- 

 senting, then, the best measure of size, this use of work units in the 

 table emphasizes the importance of a gpod-sized business in the farm 

 economy. 



The relation of man Avork units per farm to various other factors is 

 shown in Table 40. All figures given in Tables 39 and 40 that relate 

 to factors of size increased with this measure, — number of men, num- 

 ber of horses, number of cows, total capital and acres in crops. Some 

 of the other factors listed afford a clue to the reason why size is im- 

 portant in the farm economy.

* Houses and barns only. 

 ** Automobiles and milking machines not included. 



The larger average incomes of the larger farm businesses were due 

 primarily to greater efficiency in the use of human labor, horses, ma- 

 chinery, and capital. A particularly striking relationship is show^n in 

 the output index (see definitions), which measures the relative quan- 

 tity of farm products produced per man. 



In this study, it was found that the larger farm businesses obtained 

 higher average yields both of animals and of crops. Because of this 

 chance relationship, the higher average labor incomes of the larger 

 farms shown in Tables 35 to 39 were due in part to their higher aver- 

 age yields.
