One morning, I noticed a man with a chainsaw cutting down a large tree in front of some local farm buildings. He was still there in the afternoon, working on the tree stump with his power tool set at an unusual angle. Days later, I passed the place again and noticed the stump had been transformed into a replica of a corncob. The man hadn’t been merely toppling a tree; he had sculpted vertical rows of corn kernels framed by a husk—the agricultural icon of the Midwestern United States.
