The Rose Grimms' fairy tale, legend

There was once a poor woman who had two children. The youngest had to go every day into the forest to fetch wood. Once when she had gone a long way to seek it, a little child, who was quite strong, came and helped her industriously to pick up the wood and carry it home, and then before a moment had passed the strange child disappeared. The child told her mother this, but at first she would not believe it. At length she brought a rose home, and told her mother that the beautiful child had given her this rose, and had told her that when it was in full bloom, he would return. The mother put the rose in water. One morning her child could not get out of bed, the mother went to the bed and found her dead, but she lay looking very happy. On the same morning, the rose was in full bloom.
