There was a time when you had to go the farmer for your milk an d eggs. The farmer took something he or she needed, maybe some corn that you grew in your fields. This exchange of products is called barter. The barter system is based on reciprocal gifts: "if i give some corn, will you give me some eggs?" Barter worked before money existed.
Before that system, people didn`t have anything like money. They helpedeach other and gave each other thing. If they killed a bison together, they would cook the meat and share it with everybody in the community. If a man needed to build a house or hut, other men helped him.
Barter also included physical labor. Men and women worked in exchange for food.
