farm increases, and for all these items combined the annual cost per 

 acre decreases, as the farms become larger. On the 66 farms of 60 

 acres and under in area, the annual cost per farm was $127 and the 

 total annual cost per acre was $2.85; on the 124 farms of 61 to 100 

 acres in area, the annual cost per farm was $167 and the annual cost 

 per acre was $1.99; on the 72 farms of 101 to 160 acres in area, the 

 annual cost per farm was $221 and the annual cost per acre was $1.71 ; 

 and on the 38 farms of 160 acres and over in area the annual cost 

 per farm was $303 and the total annual cost per acre was $1.36. 



QUALITY OF FARM BUSINESS. 



Quality, as shown in the yield of crops and the income per animal 

 unit, and especially the income per cow, exerts a great influence on 

 the income derived from the farms of Lenawee County. From these 

 standpoints there are marked differences in the farms surveyed. 

 While the crop yields on the average are good, there are numerous 

 farms on which the yields of practically all crops are much below the 

 average, and other farms on which the crop yields are far above the 

 average. There is a great variation also in income per animal unit 

 and the income per cow. This makes it possible to show the con- 

 trast in labor income as affected by these factors, 



CROPS AND LIVE STOCK. 



In studying the data secured from a survey of this nature it is not 

 an easy matter to separate entirely the two important factors of crop 

 yields and income per animal unit; hence it is necessary to present 

 the two together. Table XIV shows the. combined effect of crop 

 yields and live stock on the 300 owner-farms, but the arrangement 

 of the figures makes it possible to study the influence of each inde- 

 pendently of the other.
