COOEDINATION OF ENTERPRISES 83 



as regards soil fertility and yet not conflict with 

 corn or hay in labor while bringing in more 

 money, the other crop should be raised. If corn 

 could be correspondingly replaced, more profit 

 would accrue to the farmer. But because corn 

 brings in larger returns than hay is not a rea- 

 son for adding more corn land to the rotation. 

 The farmer is already producing as much corn 

 as he and his team can care for, and to add more 

 corn land would add to the labor cost on the 

 farm. To produce corn and hay is not to in- 

 crease the labor cost, but simply to use labor 

 which would otherwise be unproductive. This 

 principle of coordination, into which enters di- 

 versity, rotation, and, to a degree, size of busi- 

 ness, is the vital one for the farmer.
