"Where can I get setting-boards for setting butterflies and moths? Is a microscope costing from $3 to $5 powerful enough to properly examine plants and insects? Is there any Chapter or society of young naturalists for exchanging specimens of natural history? If so, I would like to hear from it." Make the setting-boards yourself. The ROUND TABLE published directions for using them only a short time since. A low-priced microscope will answer very well for examining plants, but a more powerful one is needed for insects. You say "properly" examining. Much depends on how important you regard the word "properly." As a general rule, it is poor economy to purchase cheap scientific instruments. If you can afford a microscope costing $8 to $20, you will find it much more satisfactory. Might you not secure one on approval?--A New York member asks for a proof of a prize-story which the ROUND TABLE desires to have illustrated. We regret to say we have no such story at present, and no plans have been made to have our prize-stories illustrated this year. * * * * * Woman's Bicycle Distance Record. Here is an interesting query. "A. M." asks the woman's bicycle distance record. She says hers, ridden during one year, is 5700 miles. She asks if she holds the record. Let us hear from members on this interesting point. * * * * * THAT WONDERFUL SAIL. HARPER'S ROUND TABLE has rarely published a puzzle that so exercised the minds of its young friends and led to so much instructive research. A curious thing about the contest was the fact that questions thought in advance to be difficult were answered readily, while some quite easy questions were missed by almost every solver. Such an outcome has never before been known in all of these many contests. For example, the sign at the boat-landing, and the three riddles 21, 22, and 23, were put into the puzzle as "stickers." Yet more than half the solvers answered all three of the riddles, and every one of them, save perhaps a half-dozen, discovered the keys to the landing sign, much to the astonishment of the puzzle's author. Of the riddles, the one that proved the most difficult was 22. On the other hand, the "Mad Yankee" and the "Bad Lands of the Say It," both quite easy, were missed by almost everybody. Such a fact is no less astonishing than that all should guess the hard questions.
