We gave a public meeting to our parents and friends, and entertained them with music, and essays, etc., prepared on the subjects previously studied. We also had a blackboard illustration, showing the causes of wells and springs, drawn and explained by one of our boys. Again we invited the young ladies’ club to hold a meeting at our rooms, and after listening to their programme of essays, music, etc., we invited them to a banquet, cooked, arranged, and served _wholly_ by our _boys_. All pronounced it a fine success. We have had various excursions, examining gravel banks, gullies, cañons (small ones), etc. We have had experiments in chemistry, and have used the various acids, to the full satisfaction of the owner of the club-room. In order to fix in the minds the description of the different rocks, two of our young members have invented games of mineralogy,—one to be played like “Authors,” and the other like the geography game. The members like to try the latter on their adult friends, to see how much they know of the hardness, streak, chemical composition, forms of crystals, and uses of the common rocks.—L. B. Elsworth, Cor. Sec. 571, _Grand Rapids, Mich._ We organized our club in the first part of January, 1883, with about fifteen members; but we have grown, and now we have twenty-five members. We meet for one hour every Monday evening. One plan has been to call for items of interest from each of the members, and of these items we are forming a scrap-book. We have often had short talks from gentlemen upon various subjects, such as gunpowder and the care taken of it; light, and sound, and electricity with experiments. Our meetings are well attended, and the interest rather increases than otherwise.—Ed. Avery, Sec. 578, _Osceola, Iowa._ Our Chapter has a membership of twenty. We meet every Wednesday evening in a room fitted for that purpose. We have a cabinet containing a fine collection of ores, fossils, etc. Our Chapter was organized over two years ago. Since then our membership has gradually increased, and with it the interest of the members. The condition of the society is in every way promising.—Lee Burns, Sec., Box 744.
