Eastern Woodland Indians mostly made do by hunting, gathering, and growing. But people like variety and new things.
So, they traded with other groups both near and far. If your village was inland, you might head to the coast to trade for shellfish. You might bring furs from animals trapped near your rivers. In the north, the growing season is shorter. A northerner might swap salted fish for grains grown down south. You never used money. Trading was done with barter. You exchanged one type of goods for another.
