25 Years Ago – September 2001

• The General Meeting featured a presentation by Jenny McElwain, Assistant Curator of Paleobotany at the Field Museum. The title of her presentation was “Global Warming, the Greenhouse Effect and Fossil Floras. A 400 Million Year History.”
• Paleontology and Lapidary held “brag nights” for people to show off their summer finds.
• There were a few field trips in September 2021, including Sylvania, OH for Devonian marine fossils and Braceville for Mazon Creek fossils.
• The Auler’s wrote a nice report about the Thunder Bay field trip in July 2001.
• Karen’s Komments had stories about New Mexico Dinosaurs, a Chinese Pterodactyl, Chinese birds, a Spanish Sauropod, and other interesting news briefs.

50 Years Ago – September 1976

• All the Study Groups held “brag nights”, a long ESCONI tradition for the September meetings.
• The Micromount of the Month was Cerussite. A common mineral found in lead mines.
• There was a story about selling coprolites in the newsletter. The price was $1.30 a pound.
• H. Stern Jewelers, Inc. ran an extensive ad campaign announcing emeralds for sale. Rumor had it they $40,000 worth in the first week. And, 6,554 carats in two months.

70 Years Ago – September 1956

• The September Regular Meeting was a “brag night.”
• There was a report about the National Convention in St. Paul, Minnesota. Ben Hur Wilson is Historian of the American Federation of Mineralogical Societies.

• Hazel and Max Hillmer sent in a nice write up about their Mexican vacation.
• About 50 people went on a field trip to the quarry in St. Paul, Indiana on July 14th, 1956. That must have been hot, but just think of the nice things they found…
