Long ago, an Ojibway Indian naming Wenibojo went on a long trip to the forest. When he got hunger, he dug up the roots of a bush and ate them. The roots were tasted good, but they made him sick. Wenibojo looked for everything better to eat. Suddenly he heard the sounds of ducks nearby. He followed the sounds from a beautiful lake, which the ducks were eating plants. Wenibojo tasted one. To his surprise, it was wild rice! He returned his village to tell the people there about the special food. Nowadays, the Ojibways still harvests rice, but only as many as they need. They always left some rice on the farm so that the ducks can eat.
