Peter and his mother lived in a small village. They were very poor. To help his mother, Peter often collected wood from the forest. He also cut down small trees. One morning, a bird flew down from a branch and asked him not to cut down a certain tree. The bird explained that its home was in the tree.

Peter left the tree alone. The bird was happy and asked Peter to bring along an empty bag the next morning. Early the next day he went to the tree and waited for the bird.

The bird soon appeared and asked Peter to hold on its tail and follow him. They went to a faraway valley. Peter saw gold all over the place. He picked up some pieces of gold and put them into his bag. The bird told Peter that they must leave the valley before the sun came up. Peter quickly filled his bag and left for home.

He now had plenty of money for himself and his mother. Peter told his best friend about the tree, the bird and the gold. His friend wanted some gold too. He went to the same tree and pretended that he was going to cut it down. The bird asked him not to do so. The following morning it led Peter’s friend to the valley of gold. When the sun was about to rise, the bird told him to leave. The greedy(贪婪的) boy would not do so. The sun came up and he was changed into a bird.
