With a pity, the bird threw a piece of wood. With it the ant reached the bank again. While she was resting and drying herself in grass she heard a man coming up. He was walking without shoes on his feet and carrying a gun in his hand. As soon as he saw the bird, he wished to kill her, and he would certainly do so, but the ant bit(咬) him in one of his feet and at that moment the bird flew away at once.
