For September, children will explore farming, harvest and seasonal themes in the ongoing free drawing classes led by Catinka Knoth at Rockland Public Library. 80 Union St.

Students follow along with Knoth as she demonstrates drawing a variety of motifs. Knoth gears the classes for age 6 and up, including the young at heart. She expects participants to be able to work independently for the most part. Children age 10 and under need adult accompaniment, according to library policy.

Weekly themes for the month will be: Sept. 6, butterflies and monarch butterly migration; Sept. 13, farm scenes of haying and harvest, September gardens; Sept. 20, barnyard animals; Sept. 27, visits to the apple orchard and apple-picking.

Classes are free and open to the public, with all materials provided. The ongoing classes meet every Tuesday from 4 to 5 p.m. For more information, call Jean Young, children's librarian, at 594-0310.
