take care of one animal or one acre of crops, in terms of a ten-hour 

 day. For example, it takes about 10 hours of labor to cut and harvest 

 one acre of hay, and it takes about 150 hours to care for an ordinary 

 grade cow one year. Therefore, each acre of hay cut once represents 

 one man work unit, and each grade cow cared for per year represents 

 15 man work units. A list of crops and animals and their correspond- 

 ing work units for both men and horses is given in Table 27. These 

 units are developed and periodically adjusted in accordance with the 

 most recent findings of farm cost accounts.
