The flower could not, as on the previous evening, fold up its petals and sleep; it dropped sorrowfully. The boys only came the next morning; when they saw the dead bird, they began to cry bitterly, dug a nice grave for it, and adorned it with flowers. The bird's body was placed in a pretty red box; they wished to bury it with royal honours. While it was alive and sang they forgot it, and let it suffer want in the cage; now, they cried over it and covered it with flowers. The piece of turf, with the little daisy in it . was thrown out on the dusty highway.
