One morning Susan had promised to give her little bird his liberty. When she had opened the door of the cage, she ran to her Mamma, and they both watched him. He flew down and warbled the sweetest song Susan ever heard. When he had flown away, she watched him until her eyes pained her, and the tears rolled down her cheeks. She felt sorry to part with him, but she knew it was wrong to deprive him of his liberty.
