"Mab."—It is immaterial what kind of paper you use when preparing copy for printing, but it should be written only on one side.


Flora D.—Transparent tracing-paper may be made by saturating any kind of paper with boiled oil, or oil and varnish mixed, or with a solution of colorless dammar resin in benzole. It may also be made so as to receive washes of India ink by varnishing ordinary writing-paper with Canada balsam dissolved in oil of turpentine. The sheets should be hung on a line to dry, and if not sufficiently transparent, a second coat of varnish may be applied.


Mattie P., Gracie S., Lloyd E., and Others.—The puzzles with which you favor us are excellent, but unfortunately the answers are the same as those of puzzles which have already appeared in Young People, and it will therefore be impossible to print them.


J. T. Morgan and Arthur L. V.—We regret that we can not print your communications. If you will read the introductory note to the Post-office Box of Young People No. 45, you will see that it is contrary to our rules to print letters offering stamps or other things for sale.
