Collectivization in the countryside generally began with the establishment of CNT-FAI committees. These committees collectivized the soil of the rich and in some cases the soil of the poor as well. Farm buildings, machinery, transport and livestock were also collectivized. Food reserves and other amenities were stored in a communal depot under committee control. In many localities, the local committee issued its own inconvertible paper money; wages were paid with this money, the size of which was determined by the size of the family. Locally produced goods were free if abundant, or bought at the communal storage. State issued convertible money was only used in trade with regions that had not adopted this system, and trade with other anarchist regions was done by barter. Since the committee controlled all the money supply, travel to another region required getting permission and convertible money from the committee.
