“Using his copper knife, he cuts a segment of bark from a dying birch tree. Laying the birch bark on a flat rock, he scrapes the dry inner part of the bark with his knife, developing a small pile of dry fibers that resemble sawdust. The friction soon turns to heat, smoke, and flame.” — David Pompeani
