Tar is made by placing pine roots in a conical hole in the ground, lined with birch bark. They are then covered by turf, and set on fire. The turf keeps the oxygen out, so the wood doesn’t go up in flames. The sap is boiled out of the roots and runs to the bottom of the hole, where it can be collected as tar.
