Cinderella ... went to her mother's grave, and planted the branch on it, and she wept so much that her tears fell upon it and watered it. It grew and became a beautiful tree.

Cinderella went to this tree three times every day, and beneath it she wept and prayed. A white bird came to the tree every time, and whenever she expressed a wish, the bird would throw down to her what she had wished for.
