Cora E.—We fear you could not exchange living birds, especially in the winter season, as these delicate household pets are very sensitive to changes of temperature. If you can propose any safe way of effecting the exchange, we will gladly publish your request, provided you send us your full address, which this time you neglected to do.
Anna and Thomas.—By great patience and persistency you may succeed in teaching your pet crow to speak a few words, but the experiment is not often successful with the common American bird. The English raven is more easily taught to imitate the human voice.
Bob White.—Gray's Lessons in Botany is much used in elementary classes.—The educational works on art by J. D. Harding, the English artist, are excellent drawing-books, and will also give you some idea of handling colors. There are several volumes in this series, but each can be bought separately.
A Constant Reader.—The recipe you require involves the handling of so many dangerous and explosive chemicals that we are unwilling to place it before our young readers.
Bessie H. S.—Your first letter arrived too late for acknowledgment among others of its class, but your name was in the list of favors in Young People No. 26.
