A wren built her nest in a box on a New Jersey farm. The occupants of the farm-house saw the mother teaching her young to sing. She sat in front of them and sang her whole song very distinctly. One of the young attempted to imitate her. After proceeding through a few notes its voice broke, and it lost the tune. The mother recommenced where the young one had failed, and went very distinctly through with the remainder. The young bird made a second attempt, commencing where it had ceased before and continuing the song as long as it was able, and when the notes were again lost the mother began where it had stopped and completed it. Then the young one resumed the tune, and finished it. This done, the mother sang over the whole series of notes the second time with great precision, and again a young one attempted to follow her. The wren pursued the same course with this one as with the first, and so with the third and fourth, until each of the birds became a perfect songster.—Selected.
