Joe Korn of Oxford looks at a top bar bee hive at the Androscoggin Chamber of Commerce on Sunday afternoon. Korn started keeping bees last summer to pollinate his fruit trees and vegetable garden. He was one of four who came to listen to Christy Hemenway’s presentation of Gold Star Top Bar Hive Kits. “Bees are really quite fascinating,” Korn said as he described seeing the different color of pollen that his bees collect. Hemenway, left, promotes the top bar hives as a more sustainable and healthy method of beekeeping as opposed to conventional equipment.
