Turpentine Tree 

This image shows a longleaf pine tree that has been harvested for turpentine for many years. Visible at the bottom of the tree is the turpentine "box" which was carved into the bottom to catch the sap as it seeped from the tree. Along the trunk are many marks where the tree has been chipping or scarified so that it would produce sap, which could then be distilled into turpentine. On this tree, the marks go quite high, which means a ladder must have been used to harvest the sap. After trees were no longer suitable for turpentine production, they could be burned to produce tar.
