Pine trees especially in North Carolina were tapped for sap which was doubly distilled to make turpentine and rosin (aka resin)–hence the name tar heels. The trees were scored with a ledge called a “box” to collect the sap. Large numbers of slaves were used to score the trees, collect and process the sap. Zallen describes this as ...
