428, _St. Paul, Minn._ Since our organization we have had seventy-eight meetings, all at our house. As one of our number is studying for the occupation of mining engineer, and has a forge, furnace, lathe, etc., we have decided to study iron, steel, and the methods of mining and manufacturing them. We have a club-room, where we keep our cabinets, and a small library.--Philip C. Allen, Sec. 436, _Toronto, Canada._ Our president and several of our members have moved from town, so we have done comparatively nothing since I wrote you. But Charles Ashdown and I are endeavoring to get some new members, and I believe we shall have a stronger and better Chapter than ever.--David J. Howell, Sec. 439, _Wilmington, Del._ We have collected more cocoons and chrysalids this winter than ever before. Many of them are very rare, among them, _Achemon_, _P. satellitia_, _Smerinthis gemmatus_, _E. imperalis_, and _Callosama angulitera_.--Percy C. Pyle. 440, _Keene, N. H._ We have several hundred specimens, mostly _lepidoptera_ and _coleoptera_. Have found a great many fine beetles lately under the bark of dead trees and stumps where they pass the winter. We always note the place of capture of all specimens, and all other items of interest.--Frank H. Foster, Sec. 448, _Washington, D. C._ We bring to our third anniversary, a gratifying sense of well-being and desert, with promise of continued vigor. Our portfolios hold 343 reports, and every member is there represented. Our fifty books and pamphlets are read with application. We are ambitious for a children's Chapter, and long to make discoveries. Perhaps some of us may some day, and with this thrilling thought we are planning careful summer walks, with thoughtful "observation books."--Sabelle Macfarland. 450, _Fitchburg, Mass._ As we have consolidated all our Fitchburg Chapters into one, now known as No. 48, Fitchburg, A, there is no special report from 450, but I think we now have an earnest society on a solid foundation.--Geo. F. Whittemore. 453, _Oswego, N. Y._ Active. Will soon hold meetings weekly instead of fortnightly. Special study for the year has been archaeology and geology. Have been much interested in the _archeopteryx_. On archaeology, will send you a more lengthy report.--Will A. Burr, Sec. [_The promised report came in due time, and it is a masterpiece of patient work,--carefully illustrated with drawings of Indian arrow-heads, axes, pottery, needles, fish-hooks, pipes, and anvils. It covers twelve pages closely written. We value it, and have placed it carefully on file._] 460, _Washington, D. C._ This Chapter was organized in the spring of 1882 from a small association we then had; it had already existed for two years or more when we heard of the A. A. We concluded this would give us a wider scope for scientific investigations, and so made formal application for admission into the Association, which had already advanced with marvelous rapidity.
