Unlike manufactures and transportation, agriculture has undergone no radical changes in the matter of organization. Now, as has been the case for centuries, the typical farmer operates a single farm largely with his own labor and that of his family. He assumes all the business risks and enjoys all the profits. There have, however, been three developments in our agriculture which we must notice at this point. First,' farmers produce more for the markets than they formerly did, selling their products for money and buying goods which their predecessors had produced on the land and in the home. Along with this change has gone a growth of specialized farming in which each farmer concentrates on a few crops. Second, the invention and improvement of farm machinery has set free multitudes of laborers for other industries. Third, there has been a significant increase in the number of farm operators known as tenants, who, as the term signifies, do not own the land they operate.
