I have a very nice collection of insects, and would like to exchange with some one living in the South, or any other distant locality.

S. E. Thomas.—You can make a heated-air toy balloon with tissue-paper, a very light wire hoop with a cross piece, and a sponge. Cut your paper in shape like a lengthened quarter of orange peel, and after pasting the edges firmly together, joining them only at one end, paste the open end around the wire hoop. Soak the sponge with as much alcohol or turpentine as it will hold, and after fastening it securely to the cross piece of the hoop, light it, and the balloon will soon expand with the heated air, and rise. If you make the balloon of colored tissue-paper, and it rises while the sponge is still burning, the effect at night is very pretty. A bunch of tow might be used in place of a sponge.
Sadie McB.—We think the address given by the correspondent you wish to exchange with is sufficient. Write, and you will probably receive an answer.
Ed. S. K.—In Young People No. 23 you will find full directions for building a sloop-yacht.
