• Last spring, nine College of the Atlantic students spent 10 weeks in Vichy, France. The students from the United States, Mexico, the Czech Republic and El Salvador were charged with recording their journey in drawings, paintings, photography, words and video. Highlights of their work will be displayed in “Carnets de Voyage: Illustrated Travel Journals” at the college’s Ethel H. Blum Gallery in Bar Habor.

The exhibition opens Monday and runs through Oct. 26. Hours are 9 a.m. to 5 p.m. Monday through Friday.

• The Portland String Quartet opens its 2011-12 season at 2 p.m. Oct. 30 at Woodfords Congregational Church, 202 Woodfords St., Portland, with the premiere of a newly discovered string quartet by Portland native John Knowles Paine. He composed the quartet around 1855. It remained unknown until it was discovered by PSQ violist Julia Lane.

Paine was born in Portland, the son of a local music store owner who also conducted the city band. He studied under Hermann Kotzschmar, and was part of the initial “class” of the American Classical Music Hall of Fame installed in 1998.

Maine historian Earle G. Shettleworth will talk about life in Portland during the mid-19th century, when Paine lived and worked here. The lecture begins at 1 p.m.

Tickets cost $22 ($20 for seniors) and are free for ages 21 and younger.
