ROCKLAND — The Rockland Public Library hosts a History Talk and a Bog Nature Talk in July. Information on both events is as follows:

History Talk

The Rockland Public Library and the Rockland Historical Society present Andy O’Brien, Tuesday, July 19, at 6:30 p.m. This event is free and open to all, and located in the library’s Community Room.

Did you know Rockland was once a hotbed of labor radicalism where lime workers and granite cutters founded revolutionary unions? Did you know the Socialist Party of Maine was established in Rockland? And did you know three sisters launched the first society in Maine dedicated to universal suffrage for both women and African Americans? Join Andy O’Brien for a presentation on the history of Rockland’s notorious troublemakers in the 19th  and early 20th centuries who fought for equality and justice for all.

Following the program, we will adjourn to the Rockland Historical Society Museum for lemonade, cookies, and conversation. For more information, email by 5 p.m. July 19.

Bog Nature Talk

The Rockland Public Library presents Marie McNeely, Thursday, July 21, at 6:30 p.m. This event is free and open to all and takes place in the library’s Community Room with limited seating. The event will be simultaneously streamed via Zoom.

Marie McNeely.

Come learn about one of Rockland’s biggest natural climate solutions — the largest peatbog in Midcoast Maine. McNeely, director of partnerships at the Georges River Land Trust, offers a talk on the underappreciated value of peatbogs and acquaint you with the Rockland Bog, a giant sponge that stores carbon and mitigates the effect of climate change. You’ll also learn a little bit about the lore of bogs around the world and about the Rockland Bog’s history.

For more information or for Zoom links, email by 4 p.m. July 21 and identify the event you are interested in attending in the subject line.
