Discussion:
A long time ago, two boys went hunting with bows and arrows. They saw a blackbird sitting in a tree. They were hungry, so they shot the bird with an arrow and made a fire to cook the bird.
Just as the bird was ready to be eaten, a woman walked out of trees towards them. I’m very hungry,” she said to them. The boys took the cooked bird off the fire and gave it to her.
The woman sat down and ate every bit of the meat. When she finished eating, she stood up. “You boys are very kind to share what you have. I’m going to give you something in return. Come back tommorow to this exact spot.”
The next day the boys returned. They looked at the place where the fire had been. On the ground were strange tall plants with cobs covered with soft yellow seeds. The boys had never seen anything like it.
“Let’s take this home and ask somebody what it is,” they said.
No one in the village knew what it was. They all tasted it and liked it. What should this delicious present be called? The boys said, “We shall call it Tanchi.” And that is how Tanchi, or corn, came to be.
