C. N. C.—The specimen you send is a postmark. For purposes of exchange it is better to cut the postmark square, as it is more easily pasted in an album in the manner described in an article on "Stamp Collecting" in Young People No. 54, which has been applied by many of our readers to postmarks as well.
We have been requested to bring to the notice of those correspondents who may write to Judith Wolff, of Barranquilla, that they can not receive answers to their letters sooner than six or eight weeks.
"Electricity."—"The Brave Swiss Boy" has not been published in book form. The entire story, however, is contained in the first nine numbers of Young People, Vol. I.
Virgie McL.—We are very sorry to disappoint you, but our Post-office Box is so crowded that we can not give up space to your poem. Neither can we print your offer of exchange, for reasons which were given in the introductory paragraph to the Post-office Box of Young People No. 45.
Nellie A. B.—See answer to William D. in the Post-office Box of No. 64.
