Roger Moody, former Camden Town Manager turned author, will present an illustrated talk about his book “Logging Towboats and Boom Jumpers, The Story of O.A. Harkness” Thursday, March 28, at 2 p.m. in the Community Room of Rockland Public Library, 80 Union St.

Orris Albert “O.A.” Harkness was a true mechanical genius. From 1903 to 1951, he contributed significantly to the success of the Penobscot Log Driving Company and the Great Northern Paper Company in Maine’s Penobscot River timberlands by utilizing the developing technologies of the times to move logs efficiently to paper mills. His career began with designing and constructing several log boom tow boats and included designing dozens of  “boom jumpers.” His responsibilities expanded to include oversight of a complex 3000-foot tramway, steam and gasoline-powered Lombard log haulers, a specialized railroad, sophisticated pulpwood conveyors and crawler tractors, all to move harvested logs to and along the waters of the east and west branches of the Penobscot River, initially to sawmills and then to paper mills.

The book includes many photographs of the time, as it explores logging in the Penobscot and Allagash watersheds. It also contains expansive historical information about the many aspects of logging in the first half of the 20th century. After the talk, books will be available for purchase and signing.

Moody’s own history includes an undergraduate education at the University of Maine; a graduate degree from Syracuse University; many years of municipal and school management in Maine; and service for eight years as a Knox County Commissioner.

This event, sponsored by the Friends of the Rockland Library and the library, is free and open to the public. For more information, call 594-0310.
