TBT Chippers and dippers (cont.): When slash and longleaf pine trees are wounded or chipped, they exude a resinous gum to aid in healing the scar and to prevent insect attack. Our ancestors took notice of this and began systematically chipping trees to collect the gum by means of cups and gutters. Each week, except during the winter months, a V-shaped streak, was cut on the upper side of the face, which is the scarred area covering one-third of the circumference of the tree. Every 2 to 4 weeks the gum which flowed into the cup was collected and taken to a still. This collecting process is called dipping. At the still, the gum is distilled into turpentine and rosin. Turpentine is used in the manufacture of paints, varnishes, shoe polish, leather dressing, oils, greases, linoleum, oilcloth, roofing, and the like. Rosin is used in the manufacture of paper, size, soap, paints, varnishes, chemicals and pharmaceuticals, matches, etc.
