Despite the elaborate territorial division of labor which this country enjoys, there still remains, in addition to retailing, a considerable volume of local trade. Most farmers have surpluses of eggs which they exchange for groceries, while many of them follow the practice of making a few extra pounds of butter each week for the local trade. Very often they buy and sell grain, hay, and foodstuffs among themselves, and even make barter exchanges. Likewise people in the towns and smaller cities have business relations differing somewhat from ordinary retailing. They exchange labor and even commodities. If we could include retailing under the head of local trade, it would, of its very nature, be the most important of all trade, since all goods except those exchanged directly are finally retailed.
